如何在node.js中发出HTTP POST请求？

Question

如何在node.js中使用数据发出出站HTTP POST请求？

Answer 1

如果您使用请求库,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.

要安装请求使用命令 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.

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);
});

Answer 4

我将Restler和Needle用于生产目的.它们比原生的httprequest强大得多.可以通过基本认证,特殊标题输入或甚至上传/下载文件进行请求.

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

在 Node.js 18 中

拿来

JavaScript 中的 fetch() 方法用于从服务器请求数据。该请求可以是以 JSON 或 XML 形式返回数据的任何类型的 API。

告别node-fetch 包、axios和request ……现在fetch API 默认在全局范围内可用。

app.get('/', (req, res, next) => {
    // Make a post Request.
    fetch('https://jsonplaceholder.typicode.com/posts', {
        method: 'POST',
        body: JSON.stringify({ title: 'foo', body: 'bar', userId: 1 }),
        headers: { 'Content-type': 'application/json; charset=UTF-8' },
    })
        .then((response) => response.json())
        .then((json) => console.log(json))
        .catch(error => {
            console.log(error)
        })
        
    res.send('Fetch API is available on the global scope by default')
})

async在和的帮助下await

app.get('/', async (req, res, next) => {
    const response = await fetch('https://jsonplaceholder.typicode.com/posts', {
        method: 'POST',
        body: JSON.stringify({ title: 'foo', body: 'bar', userId: 1, }),
        headers: { 'Content-type': 'application/json; charset=UTF-8' },
    })

    const posts = await response.json();
    res.send(posts)
})

我们可以像在浏览器中一样发出请求。

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

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.

只需执行以下操作:

    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 8

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.

一个这样的图书馆是Unirest

要安装它,请使用npm.
$ npm install unirest

以及Hello, World!每个人都习以为常的例子.

var unirest = require('unirest');

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

额外:
很多人也建议使用请求 [2]

值得注意的是,幕后Unirest使用了request库.

Unirest提供直接访问请求对象的方法.

例:

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

var https = require('https');


/**
 * HOW TO Make an HTTP Call - POST
 */
// do a POST request
// create the JSON object
jsonObject = JSON.stringify({

Answer 10

这是我用来发出请求的最简单方法:使用'request'模块.

安装'request'模块的命令:

$ 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"http"模块发出请求.

Answer 11

我喜欢superagent的简单性(https://github.com/visionmedia/superagent).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node-fetch(https://www.npmjs.com/package/node-fetch),它有一个与fetch浏览器匹配的API - 但是这需要手动查询字符串编码,不会自动处理内容类型,或者所以任何其他工作都是超级的.

Answer 12

如果您正在寻找基于承诺的HTTP请求,那么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));

要么

await axios.post('/user', {firstName: 'Fred',lastName: 'Flintstone'})

Answer 13

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. 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. 要求

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.本机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();

发布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.

首先通过npm install request --save在控制台中安装require包

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)
               }
    );

Answer 15

我发现了一个视频,解释了如何实现这一目标:https://www.youtube.com/watch？v = nuuw48-u3Yrg

它使用默认的"http"模块以及"querystring"和"stringbuilder"模块.应用程序从网页中获取两个数字(使用两个文本框),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("                 <td><input type='text' id='txtFirstNo' name='txtFirstNo' /></td>");
    }

    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);
    }
    else {
        sb.appendLine("                 <td><input type='text' id='txtSecondNo' name='txtSecondNo' /></td>");
    }

    sb.appendLine("             </tr>");
    sb.appendLine("             <tr>");
    sb.appendLine("                 <td><input type='submit' value='Calculate' /></td>");
    sb.appendLine("             </tr>");

    if (data && data.txtFirstNo && data.txtSecondNo) {
        var sum = parseInt(data.txtFirstNo) + parseInt(data.txtSecondNo);
        sb.appendLine("             <tr>");
        sb.appendLine("                 <td>Sum: {0}</td>", sum);
        sb.appendLine("             </tr>");
    }

    sb.appendLine("         </table>");
    sb.appendLine("     </form>")
    sb.appendLine(" </body>");
    sb.appendLine("</html>");
    sb.build(function (err, result) {
        resp.write(result);
        resp.end();

Answer 16

这是我对POST和 的解决方案GET。

关于Post方法：

如果主体是一个 JSON 对象，那么反序列化它JSON.stringify并可能相应地设置Content-Lenght标头很重要：

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

在将其写入请求之前：

request.write( bodyString );

关于两者Get和Post方法：

该timeout可作为一个socket断开连接，所以你必须注册自己的处理程序，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') );
        });

我强烈建议注册这两个处理程序。

响应正文是分块的，因此您必须在data处理程序中连接块：

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

在end该body将包含整个响应正文：

      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 theJSON.parse`包装是安全的，因为您不能确定它实际上是一个格式良好的 json，并且在您执行请求时无法确定它。

var headers = {
    'Content-Type' : 'application/json',
    'Accept' : 'application/json' 
};
var params = {
  "dir" : "post-test"
};
var method = 'post.php';

api.Post(method, headers, params, body
    , function(response) { // success
       console.log( response );
    }
    , function(error) { // error
      console.log( error.toString() );
    }
    , function(error) { // timeout
       console.log( new Error('timeout error') );
    });

在创建一个低级实用程序来处理帖子并获取项目请求时付出了很多努力之后，我决定在这里发布我的努力。关于已接受的答案，这里是一个用于发出 http 和 https POST 请求以发送 JSON 数据的代码片段。

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
    });

}

Axios 是一个基于 Promise 的 HTTP 客户端，适用于浏览器和 Node.js。Axios 可以轻松地向 REST 端点发送异步 HTTP 请求并执行 CRUD 操作。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);
        })
