c# - 实体太大错误

Question

我的服务有点问题。它不支持大量数据，我必须为它发送一个 base64 编码的图像。服务配置是这样的:

[OperationContract]
[WebInvoke(Method = "POST", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, UriTemplate = "create", BodyStyle = WebMessageBodyStyle.Bare)]
WSResult<WebService.Model.Order> create(WSOrderCreateParams paramsData);

并且 web.config 具有以下配置:

<system.web>
    <compilation targetFramework="4.5" debug="true" />
    <httpRuntime targetFramework="4.5" maxRequestLength="1000000000"/>
<system.web>
...
<service.serviceModel>
...
  <webHttpBinding>
    <binding name="WebHttpEndpointBinding"
      maxBufferPoolSize="2147483647" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647"
      transferMode="Buffered" useDefaultWebProxy="true">
      <readerQuotas maxDepth="2000000" maxStringContentLength="2147483647" maxArrayLength="2147483647"
        maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
      <security mode="TransportCredentialOnly">
        <transport clientCredentialType="Windows"/>
      </security>
    </binding>
  </webHttpBinding>
...
</service.serviceModel>
...
<services>
  <service name="WebService.ws.Order">
    <endpoint address="" behaviorConfiguration="Web" binding="webHttpBinding" contract="WebService.ws.IOrder"/>
  </service>
</services>

谁能帮帮我？

我已经通过网络配置解决了它。这就是 Web.config 现在的样子:

<system.web>
  <compilation targetFramework="4.5" debug="true" />
  <httpRuntime targetFramework="4.5" maxRequestLength="1000000000"/>
<system.web>
    ...
<service.serviceModel>
  ...
  <webHttpBinding>
    <binding name="WebHttpEndpointBinding"
      maxBufferPoolSize="2147483647" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647"
      transferMode="Buffered" useDefaultWebProxy="true">
      <readerQuotas maxDepth="2000000" maxStringContentLength="2147483647" maxArrayLength="2147483647"
        maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
      <security mode="TransportCredentialOnly">
        <transport clientCredentialType="Windows"/>
      </security>
    </binding>
  </webHttpBinding>
  ...
</service.serviceModel>
    ...
<services>
  <service name="WebService.ws.Order">
    <endpoint address="" bindingConfiguration="WebHttpEndpointBinding" behaviorConfiguration="Web" binding="webHttpBinding" contract="WebService.ws.IOrder"/>
  </service>
</services>
...
<system.webServer>
  <security>
    <requestFiltering>
      <requestLimits maxAllowedContentLength="1073741824" />
    </requestFiltering>
  </security>
  <serverRuntime uploadReadAheadSize="2147483647" />
</system.webServer>

我已经在服务中添加了 bindingConfiguration，就像@kei 说的那样，并且

<serverRuntime uploadReadAheadSize="2147483647" /> 

在 system.webServer。 IIS 的默认池不允许您使用 uploadReadAheadSize，因此您必须继续:IIS 管理器 > 配置编辑器 > 部分:system.webServer/serverRuntime > 解锁部分。这样做，它应该工作:)
