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();
    });

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

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)
            }
        });

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);

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'})
