我正在使用一个 wsHttpBinding 服务，该服务从现在开始运行良好。我的 WPF 应用程序（客户端）连接到它，并每 15 秒自动从服务器接收信息。

我注意到有时（偶尔，有些日子没有问题）我的客户会收到以下异常：

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: '<html>
    <head>
        <title>  </title>
        <script type="text/javascript">
        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<s.length;i++){bi=s[i];wd=Math.abs(w-bi[0]);hd=Math.abs(h-bi[1]);if(wd<=2&&hd<=2){b=true;p=bi[2];}}if(b||(w<100&&w!==0)||(h<100&&h!==0)){if(p&&self==parent){self.close();return;}return'/b'+'anner.php?w='+w+'&h='+h+'&d='+d+'&u='+u+'&r='+r+'&view='+v;}else{return c;}}
        </script>
    </head>
    <body onLoad="window.l'.

你知道在哪里解决这个问题吗？

谢谢，卡米尔。

我猜您连接的服务有时会出现问题，并以 html 错误页面进行响应。这可能是 404 页面未找到或 503 服务不可用或 500 内部服务器错误。

这似乎与安全协商有关。您的安全上下文有可能被缓存 - 因此当会话到期时，安全上下文不再有效，但它仍会尝试传递它。您可能需要检查这一点，并且每次都关闭连接。

而且您最终可能不得不实现一个重试例程（您的客户端代码来捕获该通信异常，并且当这种情况发生时，将当前的客户端对象扔掉并创建一个新的对象（类似于重试）。我必须在其中一个中执行此操作我的客户。

我希望这有帮助。

干杯，瓦格纳。
