错误如何“客户端发现响应内容类型为'text / html的'..解释 [英] How can the error 'Client found response content type of 'text/html'.. be interpreted
问题描述
我使用C＃，并通过自动生成的C＃代理对象连接到一个WebService。我打电话的方法，可长时间运行，有时超时。我得到不同的错误回来，有时我得到一个 System.Net.WebException 或 System.Web.Services.Protocols.SoapException 。这些异常有属性我可以查询找到特定类型的错误，从中我可以显示给用户带来了人性化的版本。
I'm using C# and connecting to a WebService via an auto-generated C# proxy object. The method I'm calling can be long running, and sometimes times out. I get different errors back, sometimes I get a System.Net.WebException or a System.Web.Services.Protocols.SoapException. These exceptions have properties I can interrogate to find the specific type of error from which I can display a human-friendly version of to the user.
但有时我只是得到一个出现InvalidOperationException ，它有以下消息。有什么办法，我可以理解，这是不通过字符串事我承认，那种感觉很肮脏挖什么，不是不可知的国际化，错误信息可能回来用不同的语言。
But sometimes I just get an InvalidOperationException, and it has the following Message. Is there any way I can interpret what this is without digging through the string for things I recognize, that feels very dirty, and isn't internationalization agnostic, the error message might come back in a different language.
Client found response content type of 'text/html; charset=utf-8', but expected 'text/xml'.
The request failed with the error message:

编辑：
我周围的web服务器上的方法一个try-catch。我已经调试它，和Web服务器方法返回（后一分钟左右），没有任何异常。我还添加了在Web服务未处理的异常处理程序和一个断点有没有被击中。一旦Web服务的回报，我得到这个错误在客户端，而不是结果，我的预期。
I have a try-catch around the method on the web-server. I have debugged it, and the web-server method returns (after a minute or so) without any exception. I also added an unhandled exception handler in the web service and a breakpoint there wasn't hit. As soon as the web-service returns, I get this error in the client instead of the result I expected.
推荐答案
这是发生的事情，因为在你的Web服务未处理的异常，以及.NET运行时吐出死亡的服务器错误/异常转储页它的HTML黄屏，而不是XML。
This is happening because there is an unhandled exception in your Web service, and the .NET runtime is spitting out its HTML yellow screen of death server error/exception dump page, instead of XML.
由于Web服务的消费者期待文本/ XML头，而是得到了文本/ HTML，它抛出这个错误。
Since the consumer of your Web service was expecting a text/xml header and instead got text/html, it throws that error.
您应该解决您事业超时（可能是一个漫长的SQL查询？）。
You should address the cause of your timeouts (perhaps a lengthy SQL query?).
