java - HTTP/1.1 500 网页运行时出现内部服务器错误 Java

Question

我正在尝试与

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: 
PHPSESSID=gtr71sg82bm9gd9987qeu9gp50; path=/, Expires: Thu, 19 Nov 1981 08:52:00 GMT,

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]}

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)但使用 (f12) 之后我也收到错误 500 。

我无法检查服务器错误，因为它不是我的。

我搜索了之前像我一样的错误并发现:this和 this和 that one还有更多

他们都提供更改标题已尝试更改标题 - 但它没有解决我的问题。

我如何知道我需要哪个 header ？我还能尝试什么来修复它？

这不是一个实际的答案，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，请求网址并查看请求 header (因为您说它适用于浏览器请求) ，并与您从 Java 发出的请求进行比较
