Question

我似乎无法让我的WCF服务接受发送给它的大量数据。

我为客户端配置了maxReceivedMessageSize，可以很好地接收大数据，这不是问题。它正在向服务发送数据。

我尝试配置服务但没有运气。这是我的web.config：

<?xml version="1.0"?>
<configuration>
  <system.web>
    <compilation debug="true"/>
  </system.web>
  <system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior>
          <serviceMetadata httpGetEnabled="true"/>
          <serviceDebug includeExceptionDetailInFaults="false" />
          <serviceDiscovery />
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <services>
      <service name="Service.IService">
        <clear />
        <endpoint binding="basicHttpBinding" bindingConfiguration="MessageSizeBasic" contract="Service.IService" />
      </service>
    </services>
    <bindings>
      <basicHttpBinding>
        <binding name="MessageSizeBasic" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647">
          <readerQuotas maxDepth="32" maxStringContentLength="2147483647"
            maxArrayLength="16348" maxBytesPerRead="4096" maxNameTableCharCount="16384" />
        </binding>
      </basicHttpBinding>
      <webHttpBinding>
        <binding name="MessageSizeWeb" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647" />
      </webHttpBinding>
    </bindings>
  </system.serviceModel>
 <system.webServer>
    <modules runAllManagedModulesForAllRequests="true"/>
  </system.webServer>
</configuration>

从绑定中删除名称将使其适用于所有端点，并应产生所需的结果。如此：

<services>
  <service name="Service.IService">
    <clear />
    <endpoint binding="basicHttpBinding" contract="Service.IService" />
  </service>
</services>
<bindings>
  <basicHttpBinding>
    <binding maxBufferSize="2147483647" maxReceivedMessageSize="2147483647">
      <readerQuotas maxDepth="32" maxStringContentLength="2147483647"
        maxArrayLength="16348" maxBytesPerRead="4096" maxNameTableCharCount="16384" />
    </binding>
  </basicHttpBinding>
  <webHttpBinding>
    <binding maxBufferSize="2147483647" maxReceivedMessageSize="2147483647" />
  </webHttpBinding>
</bindings>

另请注意，我从端点节点中删除了bindingConfiguration属性。否则你会得到一个例外。

服务类的名称是否真的 IService （在Service命名空间中）？您最初可能拥有的是name元素的<service>属性中服务类名称的不匹配。

当使用HTTPS而不是ON绑定时，将其置于与httpsTransport标记的绑定中：

    <binding name="MyServiceBinding">
      <security defaultAlgorithmSuite="Basic256Rsa15" 
                authenticationMode="MutualCertificate" requireDerivedKeys="true" 
                securityHeaderLayout="Lax" includeTimestamp="true" 
                messageProtectionOrder="SignBeforeEncrypt" 
                messageSecurityVersion="WSSecurity10WSTrust13WSSecureConversation13WSSecurityPolicy12BasicSecurityProfile10"
                requireSignatureConfirmation="false">
        <localClientSettings detectReplays="true" />
        <localServiceSettings detectReplays="true" />
        <secureConversationBootstrap keyEntropyMode="CombinedEntropy" />
      </security>
      <textMessageEncoding messageVersion="Soap11WSAddressing10">
        <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" 
                      maxArrayLength="2147483647" maxBytesPerRead="4096" 
                      maxNameTableCharCount="16384"/>
      </textMessageEncoding>
      <httpsTransport maxReceivedMessageSize="2147483647" 
                      maxBufferSize="2147483647" maxBufferPoolSize="2147483647" 
                      requireClientCertificate="false" />
    </binding>
