Question

我使用以下代码连接WCF服务。但我得到了以下错误。

内容类型application / soap + xml;服务http://demo.ca/LicenseWebService.svc不支持charset = utf-8。客户端和服务绑定可能不匹配。

代码：

var address = new EndpointAddress("http://demo.ca/LicenseWebService.svc");
var transport = new HttpTransportBindingElement();
transport.KeepAliveEnabled = false;
var binding = new CustomBinding(transport);
factory = new ChannelFactory<LicenseWebIService>(binding, address);
channel = factory.CreateChannel();

WCF服务的Webconfig：

<?xml version="1.0"?>
<configuration>
  <system.web>
    <compilation debug="true" targetFramework="4.5.2"/>
    <httpRuntime targetFramework="4.5"/>
  </system.web>
  <system.serviceModel>
    <behaviors>
        <serviceBehaviors>
        <behavior name="">
          <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true"/>
          <serviceDebug includeExceptionDetailInFaults="false"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true"/>
  </system.serviceModel>
</configuration>

之前我使用的是BasicHttpBinding，它正在运行。

BasicHttpBinding myBinding = new BasicHttpBinding();
myBinding.Name = "BasicHttpBinding_LicenseWebIService";
myBinding.Security.Mode = BasicHttpSecurityMode.None;
myBinding.Security.Transport.ClientCredentialType = HttpClientCredentialType.None;
myBinding.Security.Transport.ProxyCredentialType = HttpProxyCredentialType.None;
myBinding.Security.Message.ClientCredentialType = BasicHttpMessageCredentialType.UserName;
EndpointAddress endPointAddress = new EndpointAddress("http://demo.ca/LicenseWebService.svc");
factory = new ChannelFactory<LicenseWebIService>(myBinding, endPointAddress);
channel = factory.CreateChannel();

BasicHttpBinding代码工作正常。但我需要根据Microsoft Review of my code设置KeepAlive = false;。所以我试图用CustomBinding替换。现在我的误差超过了错误。

有人建议我使用CustomBinding解决上述问题吗？

但是，如果有人能告诉我如何在BasicHtttpBinding中设置KeepAlive = false，那也没关系。

CustomBinding通常至少需要两个元素：transport（你拥有它）和消息编码（你没有它，而WCF试图从传输中猜测它）。尝试明确添加消息编码部分（并且您可以指定编码）：

var address = new EndpointAddress("http://demo.ca/LicenseWebService.svc");
var transport = new HttpTransportBindingElement();
transport.KeepAliveEnabled = false;
var messageEncoding = new TextMessageEncodingBindingElement(MessageVersion.Soap11, System.Text.Encoding.UTF8);
var binding = new CustomBinding(new [] { messageEncoding, transport });
factory = new ChannelFactory<LicenseWebIService>(binding, address);
channel = factory.CreateChannel();

WCF中的CustomBinding中的客户端和服务绑定可能不匹配
