通过 WCF 服务上传大于 8 MB 的流

Question

我正在尝试使用 REST 配置 (webHttpBinding) 通过 window 服务上传照片（附件流），但出现此异常

这是我使用的绑定配置（我都试过了，错误依旧）

      <webHttpBinding>
        <binding name="maxRequest" maxReceivedMessageSize="2147483647">
          <readerQuotas maxDepth="64" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
          <security mode ="Transport"></security>
        </binding>

       
        <binding name="maxRequestBinding" maxBufferPoolSize="2147483647" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647"  >
          <readerQuotas maxDepth="2000000" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
          <security mode ="Transport">
          </security>
          
        </binding>

        <binding name="BasicHttpBinding_IFileService" closeTimeout="00:01:00"
          openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"
          allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
          maxBufferPoolSize="2147483647" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647"
          transferMode="Buffered" useDefaultWebProxy="true" 
          >
          <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647"
            maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />

          <security mode ="Transport"></security>
        </binding>

我也尝试过此处发布的 IIS 解决方案

https://techcommunity.microsoft.com/t5/iis-support-blog/solution-for-request-entity-too-large-error/ba-p/501134

然而，上述所有方法都不起作用。

这是我的端点行为

      <endpointBehaviors>
        <behavior name="rest">
          <webHttp faultExceptionEnabled="true" helpEnabled="true"/>
          <dataContractSerializer maxItemsInObjectGraph="1365536" />
        </behavior>
      </endpointBehaviors>

这是合同

有关详细信息，图像大小仅为 100KB。

WCF默认传输消息大小为64KB，需要使用MaxReceivedMessageSize设置传输消息大小。

<system.serviceModel>
    <services>

        <service name="ConsoleApp1.RawDataService" behaviorConfiguration="ServiceBehavior">
            <host>
                <baseAddresses>
                    <add baseAddress="http://localhost:8012/ServiceModelSamples/service"/>
                </baseAddresses>
            </host>

            <endpoint address=""
                      binding="webHttpBinding"
                      contract="ConsoleApp1.IReceiveData"
                      behaviorConfiguration="ESEndPointBehavior" bindingConfiguration="RestfullwebHttpBinding"/>
        </service>
    </services>
    <bindings>
        <webHttpBinding>
            <binding name="RestfullwebHttpBinding" maxReceivedMessageSize="2147483647" maxBufferPoolSize="2147483647" maxBufferSize="2147483647">
            </binding>
        </webHttpBinding>
    </bindings>
    
    
    <behaviors>
        <endpointBehaviors>
            <behavior name="ESEndPointBehavior">
                <webHttp helpEnabled="true"/>
            </behavior>
        </endpointBehaviors>

        <serviceBehaviors>
            <behavior name="ServiceBehavior">
                <serviceMetadata/>
                <serviceDebug includeExceptionDetailInFaults="true" />
            </behavior>
        </serviceBehaviors>

    </behaviors>

</system.serviceModel>

您需要将 RestfullwebHttpBinding 应用到端点。

如果问题仍然存在，请随时告诉我。
