Question

如何在node.js中使用数据发出出站HTTP POST请求？

Answer 1

如果您使用request库，这会变得更容易。

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);
        }
    }
);

除了提供一个很好的语法，它使json请求变得容易，处理oeuth签名（对于twitter等），可以做多部分表单（例如用于上传文件）和流式传输。

安装请求使用命令npm install request

以下是使用node.js向Google Compiler API发出POST请求的示例：

// 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);
  }
});

我已更新代码以显示如何从文件发布数据，而不是硬编码字符串。它使用async fs.readFile命令来实现此目的，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，则进程以负值退出以指示失败。

Answer 3

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

var request = require('request');

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);
});

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);
});

Answer 4

我将Restler和Needle用于制作目的。它们比原生的httprequest更强大。可以通过基本认证，特殊标题输入或甚至上传/下载文件来请求。

至于post / get操作，它们比使用httprequest的原始ajax调用更简单。

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

Answer 5

您还可以使用Requestify，这是我为nodeJS +编写的非常酷且简单的HTTP客户端，它支持缓存。

请执行以下操作：

    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();
    });

Answer 6

简单且无依赖性。使用Promise以便等待结果。它返回响应主体，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 body = Buffer.concat(chunks);
                switch(res.headers['content-type']) {
                    case 'application/json':
                        body = JSON.parse(body);
                        break;
                }
                resolve(body)
            })
        })
        req.on('error',reject);
        if(body) {
            req.write(body);
        }
        req.end();
    })
}

用法：

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',
    })
})

Answer 7

对于那些晚年来到这里的人。现在有各种不同的库可以用最少的编码来实现这一点。除非你绝对需要控制低级HTTP的东西，否则我更喜欢优雅的轻量级库来处理HTTP请求。

一个这样的库是Unirest

要安装它，请使用npm。
$ npm install unirest

以及每个人都习以为常的Hello, World!示例。

var unirest = require('unirest');

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

的额外：
很多人也建议使用request [ 2 ]

值得注意的是，幕后Unirest使用request库。

Unirest提供了直接访问请求对象的方法。

示例：

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

Answer 8

这是我用来提出请求的最简单方法：使用＆＃39; request＆＃39;模块。

安装＆＃39;请求＆＃39;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)

});

您还可以使用Node.js的内置＆＃39; http＆＃39;模块发出请求。

Answer 9

我喜欢superagent（https://github.com/visionmedia/superagent）的简单性。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)
})

还有节点提取（https://www.npmjs.com/package/node-fetch），其API与浏览器中的fetch匹配 - 但这需要手动查询字符串编码，不会自动处理内容类型，或者任何其他工作的成就了。

Answer 11

有几十个可用的开源库，可用于在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。 Needle

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。 Request

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。 Native HTTPS Module

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可以很好地完成其工作。

  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'})

Answer 13

发布休息/ 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。

首先在您的控制台中安装require包 npm安装请求--save

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)
               }
    );

我找到了一段视频，解释了如何实现这一目标：https://www.youtube.com/watch?v=nuw48-u3Yrg

它使用默认＆＃34; http＆＃34;模块和＆＃34; querystring＆＃34;和＆＃34; stringbuilder＆＃34;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总和（以及保留文本框中的值）。这是我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("             </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);

Answer 15

Axios是用于浏览器和Node.js的基于Promise的HTTP客户端。 Axios使向REST端点发送异步HTTP请求和执行CRUD操作变得容易。可以在普通JavaScript中使用，也可以在Vue或React之类的库中使用它。

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);
        })

Answer 16

在创建一个低级实用程序来处理帖子并获取项目请求后经过很多努力，我决定在这里发布我的努力。在接受的答案中，这里有一个用于发送http和https POST请求以发送JSON数据的片段。

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
    });

}

Answer 17

这是我对POST和GET的解决方案。

关于Post方法：

如果正文是JSON对象，那么使用JSON.stringify对其进行反序列化非常重要，并可能相应地设置Content-Lenght标题：

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

在将其写入请求之前：

request.write( bodyString );

关于Get和Post方法：

timeout可以作为socket断开连接发生，因此您必须注册其处理程序，如：

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request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') );
        });

我强烈建议注册两个处理程序。

响应正文被分块，所以你必须在data处理程序中连接块：

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

end body将包含整个回复正文：

      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());
        }
      });

用try ... catch the JSON.parse`包装是安全的，因为你不能确定它实际上是格式良好的json而且没有办法确定你提出要求的时候。

发布另一个axios.post请求的axios示例，该请求使用其他配置选项和自定义标头。

var postData = {
  email: "test@test.com",
  password: "password"
};

let axiosConfig = {
  headers: {
      'Content-Type': 'application/json;charset=UTF-8',
      "Access-Control-Allow-Origin": "*",
  }
};

axios.post('http://<host>:<port>/<path>', postData, axiosConfig)
.then((res) => {
  console.log("RESPONSE RECEIVED: ", res);
})
.catch((err) => {
  console.log("AXIOS ERROR: ", err);
})

Answer 19

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);
});

或者您可以使用此库：

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);

使用request依赖。

简单的解决方案：

 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)
            }
        });

Answer 21

Request-Promise提供基于承诺的响应。 2xx以外的http响应代码将导致承诺被拒绝。可以通过设置options.simple = false

覆盖

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...
});

如何在node.js中发出HTTP POST请求？

21 个答案:

1。 Axios（推荐）

2。 Needle

3。 Request
