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)不匹配

Question

我试图使用独立的应用程序使用WCF web服务。我可以使用Internet Explorer查看此服务，也可以在Visual studio服务引用中查看。

这就是我得到的错误

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).

如何更改它以使用正确的内容类型？

这是我的配置文件

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<startup> 
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
</startup>
<system.serviceModel>
    <bindings>
        <basicHttpBinding>
            <binding name="G2WebServiceSoap11Binding" />
        </basicHttpBinding>
        <customBinding>
            <binding name="G2WebServiceSoap12Binding">
                <textMessageEncoding messageVersion="Soap12" />
                <httpTransport />
            </binding>
        </customBinding>
    </bindings>
    <client>
        <endpoint address="http://XXX.XX.XX.XX:XX/janus/services/G2WebService.G2WebServiceHttpSoap11Endpoint/"
            binding="basicHttpBinding" bindingConfiguration="G2WebServiceSoap11Binding"
            contract="G2ServiceReference.G2WebServicePortType"
            name="G2WebServiceHttpSoap11Endpoint" />
        <endpoint address="http://XXX.XX.XX.XX:XX/janus/services/G2WebService.G2WebServiceHttpSoap12Endpoint/"
            binding="customBinding" bindingConfiguration="G2WebServiceSoap12Binding"
            contract="G2ServiceReference.G2WebServicePortType"
            name="G2WebServiceHttpSoap12Endpoint" />
    </client>
</system.serviceModel>

这是堆栈

您的WCF服务有可能返回HTML。在这种情况下，您将希望在服务端设置一个绑定以返回XML。然而，这是不太可能的：如果是这样的话，让我知道，我会做一个更多细节的编辑。

更可能的原因是您的服务抛出了一个错误，该错误返回一个HTML错误页。如果你想了解细节，可以看看这篇博文。

TL；DR：错误页有几种可能的配置。如果您在IIS上驻留，您将希望从WCF服务的web.config文件中删除 部分。如果没有，请提供您的服务托管场景的详细信息，我可以提出一个编辑来匹配他们。

编辑：

看到编辑后，您可以看到返回的完整错误。Apache无法判断您要调用哪个服务，因此会抛出一个错误。一旦您有了正确的endpoint--您被指向了错误的位置--服务就会正常工作。不幸的是，我无法从可用的信息中判断正确的位置，但您的操作（当前null！）或者URL不正确。
