javascript - Node.js 服务器一直在加载，但没有结果。

Question

我一直在努力让我的服务器正常工作，但是当我发送发布数据时，它一直在加载，没有给出任何结果。这是我的 noen.js 文件。

var http = require('http');
var url = require('url');

// Configure our HTTP server to respond with Hello World to all requests.
var server = http.createServer(function (request, response) {
  var queryData = url.parse(request.url, true).query;
  response.writeHead(200, {"Content-Type": "text/plain"});

  if (queryData.name) {
    // user told us their name in the GET request, ex: http://host:8000/?name=Tom
    var exec = require('child_process').exec;
    function puts(error, stdout, stderr) {sys.puts(stdout)}
    exec ("casperjs test.js " + queryData.name + '\n');

  } else {
response.end("Contact Admin - Not Working\n");
  }
});

// Listen on port 8000, IP defaults to 127.0.0.1
server.listen(1213);

谁能帮我解决这个问题？当我去

127.0.0.1:8000/?name=tom 

我没有得到任何响应，页面只是进入了一个漫长的加载循环

没有 response.end 以防 if 为真，那么响应“永不”结束。 写在 if 的底部

response.end("something");

你会得到回应；

获取响应的过程输出:
