通过 http.request 发出 post 请求时 req.body 为空 [英] req.body is empty when making a post request via http.request

问题描述

我有一个使用 bodyparser() 的 nodejs 应用程序，这条路线:

I have a nodejs app using bodyparser(), and this route :

app.post('/users', function(req, res){
  res.json(req.body)
})

当我卷曲时

curl -X POST 127.0.0.1:3000/users -d 'name=batman'

服务器发回这个json:

server sends back this json :

{ name: 'batman' }

我的问题是尝试使用 http.request 发出相同请求时，req.body 为空我在做同样的调用，这是我用 node 运行的 test.js 文件:

my problem is when trying to make the same request with http.request, req.body is empty i'm doing the same call though, here is a test.js file that i run with node :

var http = require('http');

var options = {
  host: '127.0.0.1',
  port: 3000,
  path: '/api/users',
  method: 'POST'
};

var request = http.request(options, function (response) {
  var str = '';
  response.on('data', function (chunk) {
    str += chunk;
  });

  response.on('end', function () {
    console.log(str);
  });
});

request.end("name=batman");

请求正文为空 -> {}

为什么?我试过设置 content-length 但没有做任何事情.

why ? i've tried setting content-length but does not do anything.

推荐答案

你需要传递一个 Content-Type 来告诉 bodyParser() 使用哪个解析器.对于常规表单数据，您应该使用 Content-Type: application/x-www-form-urlencoded，因此:

You need to pass a Content-Type to tell bodyParser() which parser to use. For regular form data, you should use Content-Type: application/x-www-form-urlencoded, so:

var options = {
  host: '127.0.0.1',
  port: 3000,
  path: '/api/users',
  method: 'POST',
  'Content-Type': 'application/x-www-form-urlencoded'
};

应该可以.

如果你发现自己在 node 中做了很多客户端 HTTP 请求，我衷心推荐 Mikeal Rogers'request 模块，让这些事情变得轻而易举.

If you find yourself doing a lot of client HTTP requests in node, I heartily recommend Mikeal Rogers' request module, which makes these things a breeze.
