WCF 已超过传入消息(65536)的最大消息大小配额。若要增加配额，请使用相应绑定元素上的 MaxReceivedMessageSize 属性。

今天使用WCF从数据库拉取数据时，爆出这个错误，查看Web.config看到里面maxReciveMessageSize已经设置为最大，最后通过在WCF调试器中修改配置文件中的参数，将数修改为最大，重新配置后即可运行成功。
参考博客:WCF请求数据:已超过传入消息(65536)的最大消息大小配额。若要增加配额，请使用相应绑定元素上的 MaxReceivedMessageSize 属性。

如果时客户端的接收出现问题，只需要去客户端的配置文件将配置容量进行设置即可

<bindings>
      <basicHttpBinding>
        <binding name="BasicHttpBinding_IMysqlService"  maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647" maxBufferSize="2147483647"/>
      </basicHttpBinding>
    </bindings>

其中vs自带的WCF调试器路径为：”C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\Common7\IDE\WcfTestClient.exe”

打开程序后，输入我们的服务地址即可看到wcf服务
右击配置文件->绑定，进到编辑中

在这里插入图片描述
3. 将其中的MaxBufferPoolSize MaxBufferSize MaxReceivedMessageSize修改为2147483647即可
4.
