对于：
［未解决］用Python的微信SDK wechat_sdk中parse_data时出错：ValidateSignatureError
折腾了足够长时间，还是失败
最终是：
感觉是该sdk的加密有问题
－》signature计算的有问题
－》导致即使通过调整一些代码
返回给微信端，结果也还是因为加密出错，而报错
现在，去试试，改为明文模式
先去微信端的配置改为明文：
然后再去Flask的服务器的代码中去改为明文：

然后运行后，微信端发送消息，
Flask服务器端对应的log为：

微信可以正常收到回复了：
－》
说明还是那个sdk加密有问题
算了。
暂时就先用明文模式。
以后有空再去折腾那个加密模式。
