c# - WCF - maxReceivedMessageSize

Question

我在为较大的文件设置 maxReceivedMessageSize 时遇到问题。

我得到:

The maximum message size quota for incoming messages (65536) has been exceeded. To increase the quota, use the MaxReceivedMessageSize property on the appropriate binding element.

这是我的服务器端配置:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <appSettings>
    <add key="HTTPBaseAddress" value="http://localhost:8080/WelcomeMessage/"/>
    <add key="HTTPFileTransferAddress" value="http://localhost:8080/FileTransfer/"/>
  </appSettings>
  <system.web>
    <compilation debug="false" />
  </system.web>
  <system.webServer>
    <modules runAllManagedModulesForAllRequests="true"/>
  </system.webServer>
  <system.serviceModel>
    <services>
      <service name="FS.Services.MessageService" behaviorConfiguration="MyServiceTypeBehaviors">
        <endpoint contract="FS.Interfaces.IMessageService" address="" binding="wsHttpBinding"/>
    </service>
      <service name="FS.Services.FileTransferService" behaviorConfiguration="MyServiceTypeBehaviors">
        <endpoint contract="FS.Interfaces.IFileTransferService" address="" binding="basicHttpBinding" bindingConfiguration="streamedHttpBinding"/>
      </service>
    </services>
    <bindings>
      <basicHttpBinding>
        <binding name="streamedHttpBinding" 
                 messageEncoding="Text" 
                 transferMode="Streamed" 
                 maxReceivedMessageSize="400000000"/>
       </basicHttpBinding>
    </bindings>
    <behaviors>
      <serviceBehaviors>
        <behavior name="MyServiceTypeBehaviors">
          <serviceMetadata httpGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="false" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>
</configuration>

这是我的客户端配置:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.serviceModel>
    <client>
      <endpoint address="" binding="wsHttpBinding" contract="FS.Services.IMessageService"
        name="FS.Services.MessageService" />
      <endpoint address="" binding="basicHttpBinding" bindingConfiguration="streamedHttpBinding"
        contract="FS.Services.IFileTransferService" name="FS.Services.FileTransferService" />
    </client>
    <bindings>
      <basicHttpBinding>
        <binding name="streamedHttpBinding" maxReceivedMessageSize="400000000"
          messageEncoding="Text" transferMode="Streamed"/>
      </basicHttpBinding>
    </bindings>
  </system.serviceModel>
</configuration>

这是我连接客户端的方式:

BasicHttpBinding binding2 = new BasicHttpBinding("streamedHttpBinding");
EndpointAddress endpoint2 = new EndpointAddress("http://localhost:8080/FileTransfer");
ChannelFactory<IFileTransferService> channelFactory2 = new ChannelFactory<IFileTransferService>(binding2, endpoint2);
IFileTransferService proxy2 = channelFactory2.CreateChannel();
((IClientChannel)proxy2).Open();

此外，我还想使用流消息传输最大 500mb 的任何类型的文件。有人可以向我提供支持该功能的配置(或解决方案)吗？

谢谢!

您的客户端配置没有任何<client>将引用服务器的标记，并且您可以将绑定(bind)配置应用到增加的消息大小......

在您的服务器端，您需要定义服务及其端点:

<services>
   <service name="YourNamespace.YourServiceClass">
       <endpoint name="endpoint1"
                 address="http://server:8888/YourService.svc" 
                 binding="basicHttpBinding"
                 bindingConfiguration="lageMessageTransfer"
                 contract="IYourServiceContract" />
   </service>
</services>

在您的客户端端，您需要定义连接到服务端点之一的客户端端点

<client>
   <endpoint name="Default"
             address="http://server:8888/YourService.svc" 
             binding="basicHttpBinding"
             bindingConfiguration="lageMessageTransfer"
             contract="IYourServiceContract" />
</client>

更新:好的，现在我看到您的配置正常 - 但是您的客户端端点连接到哪里？你没有任何 address=定义!

 <client>
    <endpoint name="FS.Services.FileTransferService" 
              address="" 
              binding="basicHttpBinding" 
              bindingConfiguration="streamedHttpBinding"
              contract="FS.Services.IFileTransferService" />
 </client>
