WCF (413) 请求实体太大

Question

仅在上传将近 250k 的 byte[] 时出现错误，但使用相同的配置下载相同的 byte[] 数组是 fin。

我研究了 Streaming，但单个参数不起作用，而且这些文件大小很大。我已经能够上传一个 630 字节的简单文本文件，并且工作正常。

Answer 1

我对您目前的配置有疑问。为什么在端点地址中使用绝对服务地址？如果服务托管在 IIS 中，则基地址由 IIS 站点绑定模块提供。

因此我怀疑当前的实时连接没有使用这个端点地址，这导致 MaxReceivedMessageSize 设置失败。我想知道客户端实际使用的服务地址是什么。只有在正确的服务端点地址上应用配置才能生效。
已更新。
好像上面的配置是在客户端，下面的配置是在服务器端。此外，WCF 服务包含多个服务合同。
服务器端的配置没有明确声明服务是如何创建的。配置文件中既没有 Services 部分也没有 ProtocolMapping 部分。像下面的表格。

    <services>
      <service name="ConsoleApp3.TestService">
        <endpoint address="" binding="basicHttpBinding" contract="ConsoleApp3.ITestService" ></endpoint>
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"></endpoint>
      </service>
</services>

还有，

<protocolMapping>
      <add binding="webHttpBinding" scheme="http"/>
</protocolMapping>

即，它使用默认的 Basichttpbinding 来创建服务。无法将设置应用到正确的服务端点。
我建议您在服务器端尝试以下配置。

<system.serviceModel>
    <bindings>
      <basicHttpBinding>
        <binding name="mybinding" maxBufferSize="20000000" maxReceivedMessageSize="2147483647" >
          <readerQuotas maxDepth="2000000" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
        </binding>
      </basicHttpBinding>
    </bindings>
    <behaviors>
      <serviceBehaviors>
        <behavior>
          <serviceMetadata httpGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="true" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
    <protocolMapping>
      <add binding="basicHttpBinding" scheme="http" bindingConfiguration="mybinding"/>
    </protocolMapping>
  </system.serviceModel>

它还可以支持多个服务合同。
如果问题仍然存在，请随时告诉我。
