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();

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'})

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

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。

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)
})
