good afternoon, ladies and gentlemen. I would like to ask WeChat Mini Programs how to identify the QR code picture in a certain page. It is said that it is OK to preview wx.previewImage , but the option that pops up after trying to press the picture does not identify the QR code in the picture. What should I do? Is it possible that WeChat Mini Programs can"t be recognized at all?
coincidentally, I have made similar requirements. Let me tell you my test results:
1. Use wx.previewImage to identify ordinary QR codes. Wechat of Android version supports it, while IOS version does not support
2 and Mini Program QR codes. With wx.previewImage , both Android and IOS versions are perfectly identified
provides a bypass solution: boot and let the user jump to an environment other than Mini Program.
for example, open a customer service session and let the user take the initiative to send a message and send a QR code for the user. The QR code in this environment is recognizable.
PS: has seen some rickshaw Mini Program do this before, but now he can't find it.
it seems that Mini Program cannot identify the QR code by pressing as long as Wechat. The developer also intended to have this requirement before, but after checking around, he found that there was really no such function
Don't think about it, it is not supported at present.
without
Mini Program, many functions are not allowed to be done now, not even virtual support for reward.

Mini Program can't recognize other QR codes except Mini Program's QR code. As said upstairs, he can only guide
