wx.requestPayment 部分机型有时候无法发起微信支付，没有回调？Some models of wx.requestPayment sometimes fail to initiate WeChat payment, and there is no callback?
wx.requestPayment 这个方法调用的时候出现部分机型有时候无法唤起支付，success fail complete 都没回调，好像根本没调用这个方法似得。
fail success complete 都没回调结果
wx.requestPayment When this method is called, some models sometimes fail to call up payment, and success fail complete is not called back, as if this method was not called at all. After this problem occurs in some models, it is normal to re open the applet for a period of time, but it will still occur again. When debugging the real machine, the information such as noncestr, package, signtype, paysign, etc. that have problems should be copied and requested in the developer tool wx.requestPayment Method test, can normally call up payment, generate payment data should be no problem. Failure success complete
