Question

我已经搜遍了所有的解决方案，但似乎没有什么对我有用。上传大于64k的图像时，我收到了错误的400请求。它工作然后突然停止工作。没有代码更改或更改配置文件。还有什么可能影响配置文件设置？这是我的配置文件

Answer 1

在system.serviceModel / services / service中，您将绑定设置为“webHttpBinding”，但是您没有定义bindingConfiguration。问题是您没有在system.serviceModel / bindings中设置webHttpBinding。您设置了basicHttpBinding并将其名称设置为webHttpBinding！所以实际上没有使用这个完整的绑定，因为你的service-element查找默认值（因为你没有定义bindingConfiguration）webHttpBinding，而不是查找名为webHttpBinding的basicHttpBinding！这就是为什么您的上传文件因大于64k的文件而失败的原因。因为这会超过默认配额64k。我希望你理解我:)混合默认绑定名称非常容易出错;）

这个system.serviceModel-Section应该可以工作：

<services>
  <service name="EzFindWCFService.EZFindWebService" 
           behaviorConfiguration="webHttpBehavior" >
    <endpoint address="" 
              binding="webHttpBinding" bindingConfiguration="ConfigWebHttp"
              behaviorConfiguration="EzFindWCFService.EZFindWebServiceAspNetAjaxBehavior"
              contract="EzFindWCFService.EZFindWebService" />
  </service>
</services>

<behaviors>
  <endpointBehaviors>
    <behavior name="EzFindWCFService.EZFindWebServiceAspNetAjaxBehavior">
      <!--<enableWebScript />-->
      <webHttp/>
    </behavior>
  </endpointBehaviors>
  <serviceBehaviors>
    <behavior name="webHttpBehavior">
      <serviceMetadata httpGetEnabled="true" />
      <serviceDebug includeExceptionDetailInFaults="true" />
      <dataContractSerializer maxItemsInObjectGraph="2147483647" />
    </behavior>
  </serviceBehaviors>
</behaviors>

<bindings>
  <webHttpBinding>
    <binding name="ConfigWebHttp"
             openTimeout="00:10:00" closeTimeout="00:10:00" receiveTimeout="00:10:00" sendTimeout="00:05:00"
             maxBufferSize="2147483647" maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647">
      <readerQuotas maxDepth="64" maxStringContentLength="2147483647" maxArrayLength="2147483647" 
                    maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
    </binding>
  </webHttpBinding>
</bindings>

我省略了一些默认设置（例如绑定/安全性）以使配置更加苗条。还有一件事：我要小心设置Int32.MaxValue的所有配额。测试可能没问题，但是在投入生产时请记住将这些值设置下来。
