WCF服务客户端: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 [英] WCF Service Client: The content type text/html; charset=utf-8 of the response message does not match the content type of the binding
问题描述
我有一个 WCF 服务在我的本地 IIS 服务器上运行.我已将它添加为 C# 网站项目的服务引用，它添加得很好并自动生成代理类.
I've got a WCF Service running on my local IIS server. I've added it as a service reference to a C# Website Project and it adds fine and generates the proxy classes automatically.
但是，当我尝试调用任何服务合同时，出现以下错误:
However, when I try and call any of the service contracts, I get the following error:

Exception Details: System.ServiceModel.ProtocolException: The content type text/html; charset=utf-8 of the response message does not match the content type of the binding (application/soap+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: ' function bredir(d,u,r,v,c){var w,h,wd,hd,bi;var b=false;var p=false;var s=[[300,250,false],[250,250,false],[240,400,false],[336,280,false],[180,150,false],[468,60,false],[234,60,false],[88,31,false],[120,90,false],[120,60,false],[120,240,false],[125,125,false],[728,90,false],[160,600,false],[120,600,false],[300,600,false],[300,125,false],[530,300,false],[190,200,false],[470,250,false],[720,300,true],[500,350,true],[550,480,true]];if(typeof(window.innerHeight)=='number'){h=window.innerHeight;w=window.innerWidth;}else if(typeof(document.body.offsetHeight)=='number'){h=document.body.offsetHeight;w=document.body.offsetWidth;}for(var i=0;i
我还有一个控制台应用程序，它也与 WCF 服务通信，并且控制台应用程序能够正常调用方法而不会出现此错误.
I also have a console application which also communicates with the WCF Service and the console app is able to call methods fine without getting this error.
以下是我的配置文件的摘录.

这是我第一次尝试创建 WCF，所以一切都很新.非常感谢任何帮助.
This is my first attempt at creating a WCF so it's all very new. Any help is much appreciated.
推荐答案
尝试浏览到 http://localhost/ScraperService.svc 在托管服务的服务器上的 Web 浏览器中，使用客户端通常在其下运行的相同 Windows 凭据.
Try browsing to http://localhost/ScraperService.svc in the web browser on the server hosting the service, using the same Windows credentials that the client normally runs under.
我想 IIS 正在显示一些描述的 html 错误消息，而不是按预期返回 xml.
I imagine that IIS is displaying an html error message of some description instead of returning xml as expected.
当您有一个执行 Internet 过滤的 http 代理服务器时，也会发生这种情况.我对 ContentKeeper 的体验是它拦截任何 http/https 流量并将其作为非托管内容"阻止——我们得到的只是一条 html 错误消息.为避免这种情况，您可以向 Internet Explorer 添加代理服务器例外规则，以便代理不会拦截到您网站的流量:
This also can occur when you have an http proxy server that performs internet filtering. My experience with ContentKeeper is that it intercepts any http/https traffic and blocks it as "Unmanaged Content" - all we get back is an html error message. To avoid this, you can add proxy server exception rules to Internet Explorer so that the proxy doesn't intercept traffic to your site:
控制面板 > Internet 选项 > 连接 > LAN 设置 > 高级 > 代理设置
Control Panel > Internet Options > Connections > LAN Settings > Advanced > Proxy Settings
