in the place where the res.data is obtained through ACCESS_TOKEN (where the pile of garbled codes above), pay attention to adding:
responseType:'arraybuffer',
after success obtains res.data
self.imgUrl=wx.arrayBufferToBase64 (res.data);
what Wechat gives you is the binary data of the picture
you save this data as a picture on the server, and then you return the url, of this picture to Mini Program to display
you base64 this data, then give it to Mini Program, and then display
data:image/png;base64, picture base64 data ".
I solved it after referring to this link. I'm more excited. Share it. https://codeshelper.com/a/11.
can you be more detailed?
look at the data section, it seems to be a picture, because there are a lot of indescribable characters in the picture, so what you see is garbled.
it's like opening a picture in notepad, okay?
can I give a URL or http request header?
