HTTP / 1.1 500 Internal Server Error网页正常运行时获取Java

Question

I am tring to work with

HttpResponse httpResponse = httpClient.execute(method, context);

and getting this error

HttpResponseProxy{HTTP/1.1 500 Internal Server Error [Date: Mon, 23 Nov 2015 08:30:11 GMT, 
Server: Apache/2.2.20 (Ubuntu), X-Powered-By: PHP/5.3.6-13ubuntu3.8, Set-Cookie:

pre-check=0, Pragma: no-cache, Keep-Alive: timeout=5, max=100,

The webpage appears as text a web browser and showing a valid Json text (all in one line) but aftet using (f12) i also get an error 500 .

I cant check the server error because its not mine.

I had search for previous error like mine and found : this and this and that one and many more

All of them are offering changing the header have tried changing the header - but it didn't solved my problem.

How do i know which header do i need ? What else could i try to fix it ?

由于我无法发表评论，所以这不是一个实际的答案，但是您可以尝试打开开发工具（Chrome中的f12）并打开“网络”标签，向url请求并查看请求标头（因为您说它可以与浏览器请求一起使用），然后进行比较从Java发出的请求
