微信跳转app时，获取到的type为6，微信源码中type值没有6，kCommandSendAuth = 1,
kCommandSendMessageToWX = 2,

kCommandPay = 5,
kCommandLaunchMiniProgram = 19,
kCommandOpenBusinessView = 26,
kCommandJointPay = 27,

kCommandSendTdiAuth = 31,
只有这几个值，导致回调onReq(req: wxopensdk.BaseReq)方法不执行

"wxopensdk_request": {

"__type__": 6,

"message": {

"wx_media_message_description": "",

"wx_media_message_message_ext": "65913,undefined,goods",

"wx_media_message_title": ""

}

}
