Question

我读了这篇文章http://www.codeproject.com/Articles/166763/WCF-Streaming-Upload-Download-Files-Over-HTTP来通过WCF上传大文件。

我创建了相同的配置，但即使添加了属性maxReceivedMessageSize ="2147483647"，我也只上传了48kb的文件。当我尝试上传超过48kb的文件时出现错误

远程服务器返回错误：（413）Request Entity Too 大。

我错了或错过了什么？以下是我的配置

服务器配置：

<?xml version="1.0"?>

Web客户端配置：

<system.serviceModel>
    <bindings>
      <basicHttpBinding>
        <binding name="BasicHttpBinding_ITransferService" />
      </basicHttpBinding>
    </bindings>
    <client>
      <endpoint name="BasicHttpBinding_ITransferService" 
          address="http://localhost/transfer/TransferService.svc"
          binding="basicHttpBinding" 
          bindingConfiguration="BasicHttpBinding_ITransferService"
          contract="TransferService.ITransferService" />
    </client>
  </system.serviceModel>

请建议任何解决方案。

提前致谢

现在我已将配置更改为您的建议，但它仍然会引发相同的错误400或413.以下是我的测试项目。我不知道为什么？（环境：Window 7 Pro 64位，IIS7，WCF 4.0）

https://skydrive.live.com/redir?resid=BFE92959302FBAA0!105&authkey=!ANO_URChpql9gKE

我花了两周时间研究，但这也是同样的错误。

请帮帮我。提前谢谢。

嗯，客户端配置必须也定义相同的绑定配置（具有更大的传输大小），并在其端点配置中指定绑定配置！

因此，请将您的客户端配置更改为：

<system.serviceModel>
   <bindings>
      <basicHttpBinding>
        <binding name="TransferService" 
                 closeTimeout="00:10:00"
                 maxBufferPoolSize="2147483647"
                 maxBufferSize="2147483647"
                 maxReceivedMessageSize ="2147483647" 
                 openTimeout="00:10:00" 
                 receiveTimeout="00:10:00" 
                 sendTimeout="00:10:00" 
                 messageEncoding="Text"
                 transferMode="Streamed"
                 >
          <readerQuotas
            maxDepth="2147483647" 
            maxStringContentLength="2147483647"
            maxBytesPerRead="2147483647" 
            maxNameTableCharCount="2147483647" 
            maxArrayLength="2147483647"/>
        </binding>
        </basicHttpBinding>
    </bindings>

    <client>
      <endpoint name="BasicHttpBinding_ITransferService" 
          address="http://localhost/transfer/TransferService.svc"
          binding="basicHttpBinding" 
          bindingConfiguration="TransferService"
          contract="TransferService.ITransferService" />
    </client>
  </system.serviceModel>

然后你应该在客户端和服务器上具有相同的设置，然后这些设置将变得有用！

我检查了你的项目，用这个替换你的webconfig并再次更新服务参考，

  <?xml version="1.0"?>

我面临同样的问题。我在配置文件中使用此代码然后我能够上传25MB文件试试这个

<system.serviceModel>
      <bindings>
           <basicHttpBinding>
