响应消息的内容类型application / xml; charset = utf-8与绑定的内容类型（text / xml; charset = utf-8），WCF不匹配

问题描述 投票：1回答：1

我知道这个问题之前曾被问过几次，但是给出的解决方案要么对我不起作用，要么我太无知，无法完全理解如何实施解决方案。

因此，我试图运行的网站运行WCF客户端。每当尝试调用WCF服务（即，任何数据库搜索或编辑）时，它都会出现此错误

内容类型text / html;响应消息的charset = utf-8与绑定的内容类型不匹配（text / xml; charset = utf-8）。如果使用自定义编码器，请确保正确实现IsContentTypeSupported方法。响应的前1024个字节是：'

当我通过未处理的异常发生此错误时，弹出的就是这个

（注意：最后切断的行读取）

[ProtocolException: The content type text/html; charset=utf-8 of the response message does not match the content type of the binding (text/xml; charset=utf-8). If using a custom encoder, be sure that the IsContentTypeSupported method is implemented properly. The first 1024 bytes of the response were: '<!DOCTYPE html>

这是用于网站的web.config文件（我不确定问题是否在这里居中，但我有一种唠叨的怀疑）

现在，从我收集的其他问题，我收到的错误的要点是，而不是从数据库获取xml响应，我得到一个HTML页面错误。

在问这里之前，我一直在从网站主机的技术支持中获得帮助，但此时他们不确定问题是什么（或者至少，我与之交谈的人不确定）我们使用IIS尝试修改系统中的某些设置（没有真正的变化）所以我可以放心地假设该网站在IIS上托管？

非常感谢任何有关此事的帮助。

您收到500错误。这意味着在托管服务的服务器上而不是从调用者抛出错误。我的猜测是发送到服务的错误数据，如null或字符串而不是int，或者不发送服务所需的所有必需位。

要获得更详细的错误，您必须要么

a）在托管服务的服务器上运行相同的请求

例如 - 如果您对服务的调用是http://www.domain.com/service.svc?id=1，请让他们在托管服务的服务器上运行URL并向您发送错误。

b）通过修改服务的web.config来禁用自定义错误以获取实际错误

<configuration>
  <system.webServer>
    <httpErrors errorMode="Detailed" />
  </system.webServer>
  <system.web>
    <customErrors mode="Off" />
    <compilation debug="true" />
  </system.web>
</configuration>
