推送选择的是JOSN格式数据，安全模式

收到的信息解密后：

{"ToUserName":"gh_xxx","FromUserName":"oatxxx","CreateTime":1645072036,"MsgType":"text","Content":"尽快解决","MsgId":23551769997634820}

响应的JSON为

{ Encrypt: '8CtLJrp006vRIjHgbbe+lRROJDFPPzYO7Xo0dssUOV1e8fxlYKWJeh8EoD2GA0a/8t3D3VDB/1ILWMcq21aHbnfHtxXN+JN4eRz00sYFhZOigs3qhkLSrs250HbLG2j9YRHlawE9EPzO6DZZgu3nnlXerIVci/u0yMF6tKcNMA5hmZriCflBTOqhFrfjt/hTTVym2kB9rOZmdqq3CYa+SEK+A1oYDVpNGr3ujZ+b4K1F4jF+HV6PEAeSMnNnPnAr',
MsgType: 'transfer_customer_service',
ToUserName: 'oatxxx' }

密文内容是(字符串)：
{"CreateTime":1645072036,"FromUserName":"gh_xxx","MsgType":"transfer_customer_service","ToUserName":"oatxxx"}

我猜是回复的结构问题，但不知道正确的回复应该是怎样的

（响应的是JSON格式）
