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);
        })

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'})

var https = require('https');


/**
 * HOW TO Make an HTTP Call - POST
 */
// do a POST request
// create the JSON object
jsonObject = JSON.stringify({
    "message" : "The web of things is approaching, let do some tests to be ready!",
    "name" : "Test message posted with node.js",
    "caption" : "Some tests with node.js",
    "link" : "http://www.youscada.com",
    "description" : "this is a description",
    "picture" : "http://youscada.com/wp-content/uploads/2012/05/logo2.png",
    "actions" : [ {
        "name" : "youSCADA",
        "link" : "http://www.youscada.com"
    } ]
});

// prepare the header
var postheaders = {
    'Content-Type' : 'application/json',
    'Content-Length' : Buffer.byteLength(jsonObject, 'utf8')
};

// the post options
var optionspost = {
    host : 'graph.facebook.com',
    port : 443,
    path : '/youscada/feed?access_token=your_api_key',
    method : 'POST',
    headers : postheaders
};

console.info('Options prepared:');
console.info(optionspost);
console.info('Do the POST call');

// do the POST call
var reqPost = https.request(optionspost, function(res) {
    console.log("statusCode: ", res.statusCode);
    // uncomment it for header details
//  console.log("headers: ", res.headers);

    res.on('data', function(d) {
        console.info('POST result:\n');
        process.stdout.write(d);
        console.info('\n\nPOST completed');
    });
});

// write the json data
reqPost.write(jsonObject);
reqPost.end();
reqPost.on('error', function(e) {
    console.error(e);
});

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。

// 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') );
    });

这是我用来发出请求的最简单的方式:使用'request'模块。

命令安装'request'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)

});

你也可以使用Node.js内置的“http”模块来发出请求。

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...
});
