我尝试使用独立应用程序使用 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。

这是我遇到的错误

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

最佳答案

您的 WCF 服务可能正在返回 HTML。在这种情况下，您需要在服务端设置绑定(bind)以返回 XML。但是，这不太可能:如果是这种情况，请告诉我，我会进行编辑并提供更多详细信息。

更可能的原因是您的服务抛出错误，返回 HTML 错误页面。你可以看看this blog post如果您需要详细信息。

长话短说: 错误页面有几种可能的配置。如果您在 IIS 上托管，您需要删除 <httpErrors> WCF 服务的 web.config 部分文件。如果没有，请提供您的服务托管方案的详细信息，我可以进行修改以匹配它们。

编辑:

看到您的编辑后，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。一旦您拥有正确的端点，该服务就会正常工作——您指向了错误的位置。遗憾的是，我无法根据可用信息判断正确 位置是什么，但是您的操作(当前为 null !)或 URL 不正确。

关于c# - 响应消息的内容类型 application/xml;charset=utf-8 与绑定(bind)的内容类型不匹配 (text/xml; charset=utf-8)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/15481092/
