HTTP/1.1 500 Internal Server Error Get while webpage works Java

Question

我想和

一起工作

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

并收到此错误

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, 
Connection: Keep-Alive, Transfer-Encoding: chunked, Content-Type: application/json; charset=utf-8]}

该网页在网络浏览器中显示为文本，并显示有效的 Json 文本（全部在一行中）但在船尾使用 (f12) 我也收到错误 500 .

我无法检查服务器错误，因为它不是我的。

我已经搜索过像我这样的以前的错误，发现：this and 和 that one 以及更多

他们都提供改变 header 已尝试更改 header - 但它并没有解决我的问题。

我怎么知道我需要哪个 header？我还能尝试如何修复它？

这不是实际答案，因为我无法发表评论，但您可以尝试打开开发工具（Chrome 中的 f12）并打开网络选项卡，请求 url 并查看请求 headers （因为你说它适用于浏览器请求），并与你从 Java
