I need to parse the server response from my http post & puts. I originally thought all responses were going to be XML. Now I'm finding out that, for certain calls, the response I'm getting back is JSON. I have no control over the server, so changing this is not an option.
我需要解析来自http post & put的服务器响应。我最初认为所有的响应都是XML。现在我发现，对于某些调用，我得到的响应是JSON。我对服务器没有控制权，所以更改这不是一个选项。
So,I need to decide the best way to detect the data type coming back from the server. My first thought would be to attempt to parse the response as a JSON. If a JSONException is thrown, assume it is XML.
因此，我需要确定检测从服务器返回的数据类型的最佳方式。我的第一个想法是尝试将响应解析为JSON。如果抛出一个JSONException，假设它是XML。
Since I have no control over the server, I'm not sure I can count on the headers being correct.
由于我对服务器没有控制权，所以我不确定我是否可以相信标题是正确的。
Does anyone have any thoughts on the best approach?
有人对最好的方法有什么想法吗?

Just look at the content-type header in the html response. If the server is working properly, that should tell you want type of content you're getting.
看看html响应中的内容类型头。如果服务器运行正常，那么应该告诉您需要的内容类型。

As I had stated in my question, I had no control over the server and could not count on it to be set up correctly and/or be passing the appropriate headers. Otherwise, this would have been the obvious answer.
正如我在我的问题中陈述的那样，我无法控制服务器，不能指望它正确地设置和/或传递适当的头信息。否则，这将是显而易见的答案。
