Question

我正在尝试执行以下操作：发送请求。服务器应打印请求正文，然后发送一个小响应。请求的回调应该打印来自服务器的响应。

在某条线上，我做错了什么。我无法弄清楚它是什么。

服务器：

var http = require('http');

var server = http.createServer(function (request, response) {
  var reqBody = '';
  request.on('data', function (chunk) {
        reqBody += chunk;
  });

  request.on('end', function (chunk) {
    response.writeHead(200, {"Content-Type": "text/plain"});
    response.end("<h1>Hello world!</h1>");
    console.log(reqBody);
  });
});

server.listen(8000);

console.log("Server running at http://127.0.0.1:8000/");

请求：

var http = require('http');

var options = {
  host: '127.0.0.1',
  port: 8000,
  path: '/',
  method: 'GET',
  headers: {"Content-Type": "text/plain"}
};

var reqBody = "<h1>Hello!</h1>";

var req = http.request(options, function(res) {
  res.setEncoding('utf8');
  var resBody = '';

  res.on('data', function (chunk) {
    resBody += chunk;
  });

  res.on('end', function (chunk) {
    console.log('response: ' + resBody);
  });

});

req.on('error', function(e) {
  console.log('problem with request: ' + e.message);
});

req.write(reqBody);
req.end();

编辑：我得到的错误

problem with request: socket hang up

问题在于将req.write与GET合并，这是无体的。注释你的请求的倒数第二行，它会没事的。

nodejs socket在发送请求时挂起
