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)
               }
    );

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。

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
    });

}

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

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。

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'})
