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);

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);
});

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)
            }
        });

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);
        })

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。

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。
