推荐答案

必须修改绑定的最大长度设置（不适用于http运行时）

The max length setting has to be modified for your binding (not for http runtime)

 

例如： -

 

< services>

<services>

   &NBSP;  < service name =" DataService">

      <service name="DataService">

   &NBSP; &NBSP;  < endpoint address =" http：// localhost：2881 / DataService.svc" &NBSP; &NBSP; &NBSP;   

        <endpoint address="http://localhost:2881/DataService.svc"         

   &NBSP; &NBSP; &NBSP;结合= QUOT;&的WebHttpBinding QUOT; bindingConfiguration =" higherMessageSize"

         binding="webHttpBinding" bindingConfiguration="higherMessageSize"

   &NBSP; &NBSP; &NBSP; contract =" System.Data.Services.IRequestHandler">

         contract ="System.Data.Services.IRequestHandler">

   &NBSP; &NBSP;  < / endpoint>

        </endpoint>

   &NBSP;  < / service>

      </service>

    < / services>

    </services>

    < bindings>

    <bindings>

   &NBSP;  < webHttpBinding>

      <webHttpBinding>

   &NBSP; &NBSP;  < binding name =" higherMessageSize" MAXBUFFERSIZE = QUOT; 50000000" maxReceivedMessageSize = QUOT; 50000000" />

        <binding name="higherMessageSize" maxBufferSize="50000000" maxReceivedMessageSize="50000000" />

   &NBSP;  < / webHttpBinding>

      </webHttpBinding>

    < / bindings>

    </bindings>
