我已经到处搜索并尝试了所有解决方案，但似乎没有什么对我有用。上传大于 64k 的图像时，我收到错误的 400 请求。它正在工作，然后突然停止工作。也无需更改代码或更改配置文件。还有什么可能影响配置文件设置？这是我的配置文件

在 system.serviceModel/services/service 中，您将绑定设置为“webHttpBinding”，但您没有定义 bindingConfiguration。问题是您没有在 system.serviceModel/bindings 中设置 webHttpBinding。您设置了一个 basicHttpBinding 并将其名称设置为 webHttpBinding！所以实际上这个完整的绑定没有被使用，因为你的服务元素寻找一个默认的（因为你没有定义一个 bindingConfiguration）webHttpBinding 而不是一个名为 webHttpBinding 的 basicHttpBinding！这就是您上传大于 64k 的文件失败的原因。因为这将超过 64k 的默认配额。我希望你能理解我 :) 混合默认绑定名称很容易出错 ;)

更新：

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>

我遗漏了一些默认设置（例如绑定/安全），以使配置更苗条。还有一件事：我会小心地将所有这些配额设置为 Int32.MaxValue。测试可能没问题，但请记住在投入生产时设置这些值。
