onChooseAvatarThe method must be this.avatarUrl = 'data:image/jpeg;base64,' + wx.getFileSystemManager().readFileSync(res.detail.avatarUrl,'base64')converted to base64 storage.
The avatar obtained by the applet developer tool is http, and the path to the mobile phone is wxfile://tmp_, which imagewill not be displayed in the label. So here it is converted to base64 to store data
