Question

我搜索了很多关于这个问题的信息。有很多解决方案，但没有一个适合我。我尝试使用WCF服务上传图像文件。小图像上传得很好但是一旦尺寸增加就会发出错误。这是我得到的错误

the remote server returned an unexpected response: (413) request entity too large

这是我的web.config（我相信它与web.config有关）

<system.web>
    <compilation debug="true" targetFramework="4.5" />
    <httpRuntime targetFramework="4.5" />
</system.web>
<system.serviceModel>
    <bindings>
        <basicHttpBinding>
            <binding maxBufferPoolSize="2147483647" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647" messageEncoding="Text">

            </binding>
        </basicHttpBinding>
    </bindings>

            </behavior>
        </endpointBehaviors>
        <serviceBehaviors>

            <behavior>
                <!-- To avoid disclosing metadata information, set the values below to false before deployment -->
                <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
                <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
                <serviceDebug includeExceptionDetailInFaults="false" />

            </behavior>

        </serviceBehaviors>
    </behaviors>
    <protocolMapping>
        <add binding="basicHttpsBinding" scheme="https" />
    </protocolMapping>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true">

服务合同：

[OperationContract]
[WebInvoke(Method = "POST", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)]
ResponseBase SaveAlertSettings(AlertSettingInfo alertSettingInfo);

AlertSettingInfo.fileToUpload有base64string，它首先转换为流，然后作为图像文件写入服务器。它适用于小尺寸图像文件。为较大的文件引发错误，如4 mb图像文件。

必须为webHttpBinding

添加绑定

  <webHttpBinding>
    <binding name="webHttpBindingConfig" sendTimeout="05:00:00" hostNameComparisonMode="Exact" maxReceivedMessageSize="2147483647"></binding>
    <binding name="webHttpsBindingConfig" sendTimeout="05:00:00" hostNameComparisonMode="Exact" maxReceivedMessageSize="2147483647">
      <security mode="Transport">
        <transport clientCredentialType="None" />
      </security>
    </binding>
  </webHttpBinding>
