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'})

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。

这是我的POST和GET的解决方案。

关于Post方法:

如果主体是JSON对象，那么使用JSON反序列化就很重要。stringify并相应地设置content - length头:

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

在写入请求之前:

request.write( bodyString );

关于Get和Post方法:

超时可以发生在套接字断开连接时，所以你必须像这样注册它的处理程序:

request.on('socket', function (socket) {
        socket.setTimeout( self.timeout );
        socket.on('timeout', function() {
            request.abort();
            if(timeout) return timeout( new Error('request timed out') );
        });
    });

而请求处理程序是

       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') );
        });

我强烈建议把两个处理人都登记。

响应体是块的，所以你必须在数据处理程序中连接块:

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

在body的最后，它将包含整个响应体:

      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());
        }
      });

使用try…catchtheJSON进行包装是安全的。解析，因为你不能确定它实际上是一个格式良好的json，也没有办法在你做请求的时候确定它。

用法:

// Parameters
// domain: example.com
// ssl:true, port:80
// timeout: 30 secs
// debug: true
// json response:true
var api = new SimpleAPI('posttestserver.com', 80, 1000 * 10, true, true, true); 

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') );
    });

如果您需要XML请求，我将与axios库共享我的代码。

const {default: axios} = require('axios');

let xmlString = '<XML>...</XML>';

axios.post('yourURL', xmlString)
 .then((res) => {
   console.log("Status: ", res.status);
   console.log("Body: ", res.data);
 })
 .catch((err) => {
   console.error("Error: ", err);
 });

简单且无依赖。使用承诺，让你可以等待结果。它返回响应体，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 resBody = Buffer.concat(chunks);
                switch(res.headers['content-type']) {
                    case 'application/json':
                        resBody = JSON.parse(resBody);
                        break;
                }
                resolve(resBody)
            })
        })
        req.on('error',reject);
        if(body) {
            req.write(body);
        }
        req.end();
    })
}

用法:

async function main() {
    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',
        })
    })
}

main().catch(err => {
    console.log(err)
})

Request-Promise提供基于承诺的响应。 非2xx的HTTP响应代码将导致承诺被拒绝。这可以通过设置选项来覆盖。简单= false

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...
});
