下面是一个使用node.js向谷歌编译器API发出POST请求的例子:

// We need this to build our post string
var querystring = require('querystring');
var http = require('http');
var fs = require('fs');

function PostCode(codestring) {
  // Build the post string from an object
  var post_data = querystring.stringify({
      'compilation_level' : 'ADVANCED_OPTIMIZATIONS',
      'output_format': 'json',
      'output_info': 'compiled_code',
        'warning_level' : 'QUIET',
        'js_code' : codestring
  });

  // An object of options to indicate where to post to
  var post_options = {
      host: 'closure-compiler.appspot.com',
      port: '80',
      path: '/compile',
      method: 'POST',
      headers: {
          'Content-Type': 'application/x-www-form-urlencoded',
          'Content-Length': Buffer.byteLength(post_data)
      }
  };

  // Set up the request
  var post_req = http.request(post_options, function(res) {
      res.setEncoding('utf8');
      res.on('data', function (chunk) {
          console.log('Response: ' + chunk);
      });
  });

  // post the data
  post_req.write(post_data);
  post_req.end();

}

// This is an async file read
fs.readFile('LinkedList.js', 'utf-8', function (err, data) {
  if (err) {
    // If this were just a small part of the application, you would
    // want to handle this differently, maybe throwing an exception
    // for the caller to handle. Since the file is absolutely essential
    // to the program's functionality, we're going to exit with a fatal
    // error instead.
    console.log("FATAL An error occurred trying to read in the file: " + err);
    process.exit(-2);
  }
  // Make sure there's data before we post it
  if(data) {
    PostCode(data);
  }
  else {
    console.log("No data to post");
    process.exit(-1);
  }
});

我已经更新了代码，以展示如何从文件中发布数据，而不是硬编码的字符串。它使用异步文件系统。readFile命令来实现这一点，在成功读取后发布实际代码。如果出现错误，则抛出错误，如果没有数据，则进程退出，并显示一个负值以指示失败。

请求现在已弃用。建议您使用替代方案

无特定顺序且极不完整的:

const https = require('https'); node-fetch axios 得到了 搞 弯曲 make-fetch-happen unfetch tiny-json-http 针 urllib

统计比较 一些代码示例

最初的回答:

如果使用请求库，这将变得容易得多。

var request = require('request');

request.post(
    'http://www.yoursite.com/formpage',
    { json: { key: 'value' } },
    function (error, response, body) {
        if (!error && response.statusCode == 200) {
            console.log(body);
        }
    }
);

除了提供一个不错的语法，它使json请求更容易，处理oauth签名(twitter等)，可以做多部分的表单(例如上传文件)和流。

安装请求使用npm install request命令

我喜欢超级代理的简单性(https://github.com/visionmedia/superagent)。节点和浏览器上的API相同。

;(async function() {
  var response = await superagent.post('http://127.0.0.1:8125/', {age: 2})
  console.log(response)
})

还有节点获取(https://www.npmjs.com/package/node-fetch)，它有一个API来匹配从浏览器获取-然而这需要手动查询字符串编码，不能自动处理内容类型，或者超级代理所做的任何其他工作。

我使用Restler和Needle用于生产目的。 它们都比本地httprequest强大得多。可以使用基本的身份验证、特殊的头条目甚至上传/下载文件进行请求。

至于post/get操作，它们也比使用httprequest的原始ajax调用简单得多。

needle.post('https://my.app.com/endpoint', {foo:'bar'}, 
    function(err, resp, body){
        console.log(body);
});

你也可以使用Requestify，这是我为nodeJS +编写的一个非常酷而简单的HTTP客户端，它支持缓存。

只需要做以下几点:

    var requestify = require('requestify');

    requestify.post('http://example.com', {
        hello: 'world'
    })
    .then(function(response) {
        // Get the response body (JSON parsed or jQuery object for XMLs)
        response.getBody();
    });

您可以使用请求库。https://www.npmjs.com/package/request

var request = require('request');

要发布JSON数据:

var myJSONObject = { ... };
request({
    url: "http://josiahchoi.com/myjson",
    method: "POST",
    json: true,   // <--Very important!!!
    body: myJSONObject
}, function (error, response, body){
    console.log(response);
});

要发布xml数据:

var myXMLText = '<xml>...........</xml>'
request({
    url: "http://josiahchoi.com/myjson",
    method: "POST",
    headers: {
        "content-type": "application/xml",  // <--Very important!!!
    },
    body: myXMLText
}, function (error, response, body){
    console.log(response);
});

编辑:截至2020年2月，请求已弃用。

发送Rest/JSON请求 我们可以简单地使用请求包并保存我们必须在Json变量中发送的值。

首先在控制台中安装require包 NPM安装请求——保存

var request = require('request');

    var options={
                'key':'28',
                'key1':'value',
                'key2':'value'
                }

    request({
             url:"http://dev.api.ean.com/ean-services/rs/hotel/v3/ping?                      
                 minorRev="+options.key+
                 "&cid="+options.key1+
                 "&apiKey="+options.key2,
             method:"POST",
             json:true},function(error,response,body){
                     console.log(body)
               }
    );

2020年更新:

我真的很喜欢phin -超轻量级的Node.js HTTP客户端

它有两种不同的用法。一个是promise (Async/Await)，另一个是传统的回调样式。

安装通过:npm i phin

直接从它的README等待:

const p = require('phin')

await p({
    url: 'https://ethanent.me',
    method: 'POST',
    data: {
        hey: 'hi'
    }
})

未承诺(回调)风格:

const p = require('phin').unpromisified

p('https://ethanent.me', (err, res) => {
    if (!err) console.log(res.body)
})

截至2015年，现在有很多不同的库可以用最少的代码实现这一点。我更喜欢优雅的轻量级HTTP请求库，除非你绝对需要控制低级HTTP的东西。

Unirest就是这样一个库

要安装它，使用npm。 $ NPM安装unirest

然后是Hello, World!大家都熟悉的例子。

var unirest = require('unirest');

unirest.post('http://example.com/helloworld')
.header('Accept', 'application/json')
.send({ "Hello": "World!" })
.end(function (response) {
  console.log(response.body);
});

额外的: 很多人还建议使用请求[2]

值得注意的是，Unirest在幕后使用的是请求库。

Unirest提供了直接访问请求对象的方法。

例子:

var Request = unirest.get('http://mockbin.com/request');

我找到了一个视频来解释如何做到这一点:https://www.youtube.com/watch?v=nuw48-u3Yrg

它使用默认的“http”模块以及“querystring”和“stringbuilder”模块。应用程序从网页中获取两个数字(使用两个文本框)，并在提交时返回这两个数字的和(以及在文本框中持久化的值)。这是我能在其他地方找到的最好的例子。

var http = require("http");
var qs = require("querystring");
var StringBuilder = require("stringbuilder");

var port = 9000;

function getCalcHtml(req, resp, data) {
    var sb = new StringBuilder({ newline: "\r\n" });
    sb.appendLine("<html>");
    sb.appendLine(" <body>");
    sb.appendLine("     <form method='post'>");
    sb.appendLine("         <table>");
    sb.appendLine("             <tr>");
    sb.appendLine("                 <td>Enter First No: </td>");

    if (data && data.txtFirstNo) {
        sb.appendLine("                 <td><input type='text' id='txtFirstNo' name='txtFirstNo' value='{0}'/></td>", data.txtFirstNo);
    }
    else {
        sb.appendLine("                 <td><input type='text' id='txtFirstNo' name='txtFirstNo' /></td>");
    }

    sb.appendLine("             </tr>");
    sb.appendLine("             <tr>");
    sb.appendLine("                 <td>Enter Second No: </td>");

    if (data && data.txtSecondNo) {
        sb.appendLine("                 <td><input type='text' id='txtSecondNo' name='txtSecondNo' value='{0}'/></td>", data.txtSecondNo);
    }
    else {
        sb.appendLine("                 <td><input type='text' id='txtSecondNo' name='txtSecondNo' /></td>");
    }

    sb.appendLine("             </tr>");
    sb.appendLine("             <tr>");
    sb.appendLine("                 <td><input type='submit' value='Calculate' /></td>");
    sb.appendLine("             </tr>");

    if (data && data.txtFirstNo && data.txtSecondNo) {
        var sum = parseInt(data.txtFirstNo) + parseInt(data.txtSecondNo);
        sb.appendLine("             <tr>");
        sb.appendLine("                 <td>Sum: {0}</td>", sum);
        sb.appendLine("             </tr>");
    }

    sb.appendLine("         </table>");
    sb.appendLine("     </form>")
    sb.appendLine(" </body>");
    sb.appendLine("</html>");
    sb.build(function (err, result) {
        resp.write(result);
        resp.end();
    });
}

                getHome(req, resp);
            }
            else if (req.url === "/calc") {
                getCalcForm(req, resp);
            }
            else {

                        resp.writeHead(413, 'Request Entity Too Large', { 'Content-Type': 'text/html' });
                        resp.end('<!doctype html><html><head><title>413</title></head><body>413: Request Entity Too Large</body></html>');
                    }
                });
                req.on('end', function () {
                    var formData = qs.parse(reqBody);
                    getCalcForm(req, resp, formData);
                });
            }
            else {
                get404(req, resp);
            }
            break;
        default:
            get405(req, resp);
            break;
    }
}).listen(port);

这是我用来发出请求的最简单的方式:使用'request'模块。

命令安装'request'模块:

$ npm install request

示例代码:

var request = require('request')

var options = {
  method: 'post',
  body: postData, // Javascript object
  json: true, // Use,If you are sending JSON data
  url: url,
  headers: {
    // Specify headers, If any
  }
}

request(options, function (err, res, body) {
  if (err) {
    console.log('Error :', err)
    return
  }
  console.log(' Body :', body)

});

你也可以使用Node.js内置的“http”模块来发出请求。

这是我的POST和GET的解决方案。

关于Post方法:

如果主体是JSON对象，那么使用JSON反序列化就很重要。stringify并相应地设置content - length头:

      var bodyString=JSON.stringify(body)
      var _headers = {
        'Content-Length': Buffer.byteLength(bodyString)
      };

在写入请求之前:

request.write( bodyString );

关于Get和Post方法:

超时可以发生在套接字断开连接时，所以你必须像这样注册它的处理程序:

request.on('socket', function (socket) {
        socket.setTimeout( self.timeout );
        socket.on('timeout', function() {
            request.abort();
            if(timeout) return timeout( new Error('request timed out') );
        });
    });

而请求处理程序是

       request.on('timeout', function () {
          // Timeout happend. Server received request, but not handled it
          // (i.e. doesn't send any response or it took to long).
          // You don't know what happend.
          // It will emit 'error' message as well (with ECONNRESET code).
          req.abort();
          if(timeout) return timeout( new Error('request timed out') );
        });

我强烈建议把两个处理人都登记。

响应体是块的，所以你必须在数据处理程序中连接块:

      var body = '';
      response.on('data', function(d) {
          body += d;
      });

在body的最后，它将包含整个响应体:

      response.on('end', function() {
        try {
            var jsonResponse=JSON.parse(body);
            if(success) return success( jsonResponse );
        } catch(ex) { // bad json
          if(error) return error(ex.toString());
        }
      });

使用try…catchtheJSON进行包装是安全的。解析，因为你不能确定它实际上是一个格式良好的json，也没有办法在你做请求的时候确定它。

            } catch(ex) { // bad json
              if(error) return error(ex.toString());
            }
          });

        });

        request.on('socket', function (socket) {

            });
        });
        request.on('error', function (e) {
          // General error, i.e.
          //  - ECONNRESET - server closed the socket unexpectedly
          //  - ECONNREFUSED - server did not listen
          //  - HPE_INVALID_VERSION
          //  - HPE_INVALID_STATUS
          //  - ... (other HPE_* codes) - server returned garbage
          console.log(e);
          if(error) return error(e);
        });
        request.on('timeout', function () {
          // Timeout happend. Server received request, but not handled it
          // (i.e. doesn't send any response or it took to long).
          // You don't know what happend.
          // It will emit 'error' message as well (with ECONNRESET code).
          req.abort();
          if(timeout) return timeout( new Error('request timed out') );
        });

        self.requestUrl = (this.ssl?'https':'http') + '://' + request._headers['host'] + request.path;

          console.log("SimpleAPI.Post",self.requestUrl);
        }

        request.write( bodyString );
        request.end();

    } //RequestPost

    return SimpleAPI;

  })();

  module.exports = SimpleAPI

}).call(this);

用法:

// Parameters
// domain: example.com
// ssl:true, port:80
// timeout: 30 secs
// debug: true
// json response:true
var api = new SimpleAPI('posttestserver.com', 80, 1000 * 10, true, true, true); 

var headers = {
    'Content-Type' : 'application/json',
    'Accept' : 'application/json' 
};
var params = {
  "dir" : "post-test"
};
var method = 'post.php';

api.Post(method, headers, params, body
    , function(response) { // success
       console.log( response );
    }
    , function(error) { // error
      console.log( error.toString() );
    }
    , function(error) { // timeout
       console.log( new Error('timeout error') );
    });

var https = require('https');

在为我的项目创建了一个低级实用程序来处理帖子和获取请求之后，我决定在这里发布我的努力。这里有一个关于发送JSON数据的http和https POST请求的代码片段。

const http = require("http")
const https = require("https")

// Request handler function
let postJSON = (options, postData, callback) => {

    // Serializing JSON
    post_data = JSON.stringify(postData)

    let port = options.port == 443 ? https : http

    // Callback function for the request
    let req = port.request(options, (res) => {
        let output = ''
        res.setEncoding('utf8')

        // Listener to receive data
        res.on('data', (chunk) => {
            output += chunk
        });

        // Listener for intializing callback after receiving complete response
        res.on('end', () => {
            let obj = JSON.parse(output)
            callback(res.statusCode, obj)
        });
    });

   // Handle any errors occurred while making request
    req.on('error', (err) => {
        //res.send('error: ' + err.message)
    });

    // Request is made here, with data as string or buffer
    req.write(post_data)
    // Ending the request
    req.end()
};

let callPost = () => {

    let data = {
        'name': 'Jon',
        'message': 'hello, world'
    }

    let options = {
        host: 'domain.name',       // Your domain name
        port: 443,                 // 443 for https and 80 for http
        path: '/path/to/resource', // Path for the request
        method: 'POST',            
        headers: {
            'Content-Type': 'application/json',
            'Content-Length': Buffer.byteLength(data)
        }
    }

    postJSON(options, data, (statusCode, result) => {
        // Handle response
        // Process the received data
    });

}

如果您正在寻找基于承诺的HTTP请求，axios可以很好地完成它的工作。

  const axios = require('axios');

  axios.post('/user', {firstName: 'Fred',lastName: 'Flintstone'})
      .then((response) => console.log(response))
      .catch((error) => console.log(error));

OR

await axios.post('/user', {firstName: 'Fred',lastName: 'Flintstone'})

发布另一个axios的例子。Post请求，使用额外的配置选项和自定义头。

var postData = { 电子邮件:“test@test.com”, 密码:“密码” }; let axiosConfig = { 标题:{ “内容类型”:“application / json; charset = utf - 8”, “Access-Control-Allow-Origin”:“*”, ｝ }; axios。post('http://<主机>:<端口>/<路径>'，postData, axiosConfig) .then((res) => { console.log("RESPONSE RECEIVED: "， res); }) .catch((err) => { console.log("AXIOS ERROR: "， err); })

通过使用请求依赖性。

简单的解决方法:

 import request from 'request'
 var data = {
        "host":"127.1.1.1",
        "port":9008
    }

request.post( baseUrl + '/peers/connect',
        {
            json: data,  // your payload data placed here
            headers: {
                'X-Api-Key': 'dajzmj6gfuzmbfnhamsbuxivc', // if authentication needed
                'Content-Type': 'application/json' 
            }
        }, function (error, response, body) {
            if (error) {
                callback(error, null)
            } else {
                callback(error, response.body)
            }
        });

简单且无依赖。使用承诺，让你可以等待结果。它返回响应体，不检查响应状态代码。

const https = require('https');

function httpsPost({body, ...options}) {
    return new Promise((resolve,reject) => {
        const req = https.request({
            method: 'POST',
            ...options,
        }, res => {
            const chunks = [];
            res.on('data', data => chunks.push(data))
            res.on('end', () => {
                let resBody = Buffer.concat(chunks);
                switch(res.headers['content-type']) {
                    case 'application/json':
                        resBody = JSON.parse(resBody);
                        break;
                }
                resolve(resBody)
            })
        })
        req.on('error',reject);
        if(body) {
            req.write(body);
        }
        req.end();
    })
}

用法:

async function main() {
    const res = await httpsPost({
        hostname: 'sentry.io',
        path: `/api/0/organizations/org/releases/${changesetId}/deploys/`,
        headers: {
            'Authorization': `Bearer ${process.env.SENTRY_AUTH_TOKEN}`,
            'Content-Type': 'application/json',
        },
        body: JSON.stringify({
            environment: isLive ? 'production' : 'demo',
        })
    })
}

main().catch(err => {
    console.log(err)
})

let request = require('request');
let jsonObj = {};
request({
    url: "https://myapii.com/sendJsonData",
    method: "POST",
    json: true,
    body: jsonObj
    }, function (error, resp, body){
       console.log(resp);
});

或者你可以使用这个库:

let axios = require("axios");
let jsonObj = {};

const myJsonAPI = axios.create({
   baseURL: 'https://myapii.com',
   timeout: 120*1000
});

let response = await myJsonAPI.post("sendJsonData",jsonobj).catch(e=>{
    res.json(e);
});
console.log(response);

Request-Promise提供基于承诺的响应。 非2xx的HTTP响应代码将导致承诺被拒绝。这可以通过设置选项来覆盖。简单= false

var options = {
  method: 'POST',
  uri: 'http://api.posttestserver.com/post',
  body: {
  some: 'payload'
 },
  json: true // Automatically stringifies the body to JSON
};

rp(options)
.then(function (parsedBody) {
    // POST succeeded...
})
.catch(function (err) {
    // POST failed...
});

有许多可用的开源库，您可以使用它们在Node中发出HTTP POST请求。

1. Axios(推荐)

const axios = require('axios');

const data = {
    name: 'John Doe',
    job: 'Content Writer'
};

axios.post('https://reqres.in/api/users', data)
    .then((res) => {
        console.log(`Status: ${res.status}`);
        console.log('Body: ', res.data);
    }).catch((err) => {
        console.error(err);
    });

2. 针

const needle = require('needle');

const data = {
    name: 'John Doe',
    job: 'Content Writer'
};

needle('post', 'https://reqres.in/api/users', data, {json: true})
    .then((res) => {
        console.log(`Status: ${res.statusCode}`);
        console.log('Body: ', res.body);
    }).catch((err) => {
        console.error(err);
    });

3.请求

const request = require('request');

const options = {
    url: 'https://reqres.in/api/users',
    json: true,
    body: {
        name: 'John Doe',
        job: 'Content Writer'
    }
};

request.post(options, (err, res, body) => {
    if (err) {
        return console.log(err);
    }
    console.log(`Status: ${res.statusCode}`);
    console.log(body);
});

4. 本地HTTPS模块

const https = require('https');

const data = JSON.stringify({
    name: 'John Doe',
    job: 'Content Writer'
});

const options = {
    hostname: 'reqres.in',
    path: '/api/users',
    method: 'POST',
    headers: {
        'Content-Type': 'application/json',
        'Content-Length': data.length
    }
};


const req = https.request(options, (res) => {
    let data = '';

    console.log('Status Code:', res.statusCode);

    res.on('data', (chunk) => {
        data += chunk;
    });

    res.on('end', () => {
        console.log('Body: ', JSON.parse(data));
    });

}).on("error", (err) => {
    console.log("Error: ", err.message);
});

req.write(data);
req.end();

有关详细信息，请查看这篇文章。

Axios是面向浏览器和Node.js的基于承诺的HTTP客户端。Axios使向REST端点发送异步HTTP请求和执行CRUD操作变得很容易。它可以在纯JavaScript中使用，也可以与Vue或React等库一起使用。

const axios = require('axios');

        var dataToPost = {
          email: "your email",
          password: "your password"
        };

        let axiosConfiguration = {
          headers: {
              'Content-Type': 'application/json;charset=UTF-8',
              "Access-Control-Allow-Origin": "*",
          }
        };

        axios.post('endpoint or url', dataToPost, axiosConfiguration)
        .then((res) => {
          console.log("Response: ", res);
        })
        .catch((err) => {
          console.log("error: ", err);
        })

如果您需要XML请求，我将与axios库共享我的代码。

const {default: axios} = require('axios');

let xmlString = '<XML>...</XML>';

axios.post('yourURL', xmlString)
 .then((res) => {
   console.log("Status: ", res.status);
   console.log("Body: ", res.data);
 })
 .catch((err) => {
   console.error("Error: ", err);
 });

在Node.js 18

跟节点获取包、axios和request说再见吧……现在默认情况下，全局作用域中的获取API是可用的。

const res = await fetch('https://nodejs.org/api/documentation.json');
if (res.ok) {
  const data = await res.json();
  console.log(data);
}

我们可以像在浏览器中那样发出请求。

使用Node.js HTTP库进行任意HTTP请求。

不要使用不提供任何新功能的第三方包。

使用Node.js内置。

https://nodejs.org/api/http.html#httprequesturl-options-callback

示例来自文档中的http。request向你展示了如何创建一个“hello world”POST请求。

下面是一个例子。在评论中提出问题，例如，如果你正在学习Node.js，想要更多的资源。

const http = require('node:http');

const postData = JSON.stringify({
    'msg': 'Hello World!',
});

const options = { 
    hostname: 'www.google.com',
    port: 80, 
    path: '/upload',
    method: 'POST',
    headers: {
        'Content-Type': 'application/json',
        'Content-Length': Buffer.byteLength(postData),
    },  
};

const req = http.request(options, (res) => {
    console.log(`STATUS: ${res.statusCode}`);
    console.log(`HEADERS: ${JSON.stringify(res.headers)}`);
    res.setEncoding('utf8');
    res.on('data', (chunk) => {
        console.log(`BODY: ${chunk}`);
    }); 
    res.on('end', () => {
        console.log('No more data in response.');
    }); 
});

req.on('error', (e) => {
    console.error(`problem with request: ${e.message}`);
});

// Write data to request body
req.write(postData);
req.end();
