试试这个（注意 transferMode="StreamedRequest" 很重要）：

<service behaviorConfiguration="Default" name="....">
    <endpoint address="" behaviorConfiguration="Web" binding="webHttpBinding"
      bindingConfiguration="LargeWeb" contract="..." />
    <host>
      <baseAddresses>
        <add baseAddress="..." />
      </baseAddresses>
    </host>
</service>

<webHttpBinding>
    <binding name="LargeWeb"
             maxBufferSize="2147483647"
             maxBufferPoolSize="2147483647"
             maxReceivedMessageSize="2147483647"
             transferMode="StreamedRequest">
      <readerQuotas
            maxDepth="2147483647"
            maxStringContentLength="2147483647"
            maxArrayLength="2147483647"
            maxBytesPerRead="2147483647"
            maxNameTableCharCount="2147483647"/>
    </binding>
  </webHttpBinding>
