使用soap将字节数组传递给wcf

Question

在这里，当我尝试发送字节数组时，它给了我错误的请求错误。我已经检查了所有消息限制的最大值。全部设置为最大值。 但是，我可以通过将字节数组参数保持为空来将字符串值发送到服务方法。我不知道为什么会在这里发生。我还检查了服务行为配置名称和绑定配置名称（即包含的命名空间），这似乎很好。非常感谢任何帮助。

这是我的客户端代码：

....
ServiceClient ac = new ServiceClient();
string ServiceUrl = "http://localhost:20314/Service.svc";
EndpointAddress address = new EndpointAddress(ServiceUrl);
BasicHttpBinding httpbinding = new BasicHttpBinding();   
using (ChannelFactory<IServiceChannel> factory = new   ChannelFactory<IServiceChannel>(httpbinding))
{
    factory.Endpoint.Address = address;
    using (IServiceChannel oService = factory.CreateChannel())
    {

       using (OperationContextScope scope = new OperationContextScope(oService))
       {

         Guid myToken = new Guid("guid here");                      

         MessageHeader<Guid> mhg = new MessageHeader<Guid>(myToken);                       
         MessageHeader untyped = mhg.GetUntypedHeader("identity", "ns");
         OperationContext.Current.OutgoingMessageHeaders.Add(untyped);
         // here i am getting bad request error                                                               
         var fdt = (oService).GetData(bytearray, value);

         }
    }
}
.......

Answer 1

我在您的配置文件中看到了一些内容。

首先，在您的客户端配置中，您有一个 <services> 部分 - 除非您的客户端还托管服务，否则您不需要在那里。此外，您的 <services> 部分正在使用 wsHttpBinding，但您的客户端正在指定 basicHttpBinding - 客户端和服务绑定需要匹配。

其次，您在客户端为绑定设置了更高的值，但客户端绑定配置对服务器端没有影响。您没有在服务配置中定义明确的端点，因此您将获得具有默认绑定 (basicHttpBinding) 的默认端点，它具有正常的默认值。

您可以在服务配置中为basicHttpBinding 添加默认配置（通过省略name 属性），如下所示：

<bindings>
  <basicHttpBinding>        
    <binding closeTimeout="01:01:00"
             openTimeout="01:01:00" receiveTimeout="01:10:00" sendTimeout="01:01:00"
             allowCookies="false" bypassProxyOnLocal="false" 
             hostNameComparisonMode="StrongWildcard"
             maxBufferSize="2147483647" maxBufferPoolSize="2147483647" 
             maxReceivedMessageSize="2147483647"
             messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered"
             useDefaultWebProxy="true">
      <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647"
                    maxArrayLength="2147483647"
                    maxBytesPerRead="4096" maxNameTableCharCount="2147483647" />
      <security mode="None">
        <transport clientCredentialType="None" proxyCredentialType="None"
                   realm="" />
        <message clientCredentialType="UserName" algorithmSuite="Default" />
      </security>
    </binding>
  </basicHttpBinding>
</bindings>

这与您的 client.config 中的定义相同，但减去了 name 属性。 （另外，为什么您定义了传输和消息安全，但安全模式设置为“无”？）。

另一种选择是在服务配置中显式定义端点并指定要使用的绑定配置。类似于您在客户端配置文件中所做的。假设您有一个名为“BasicHttpBinding_IService”的basicHttpBinding。您的端点将如下所示：

<services>      
  <service name="LocalService.Service" behaviorConfiguration="ServiceBehavior">
    <endpoint address="http://localhost:20314/Service.svc" 
              binding="basicHttpBinding" 
              bindingConfiguration="BasicHttpBinding_IService"
              contract="LocalService.IService" />
  </service>
</services>
