Take the WeChat service account as an example. After entering the web page, call the phone's camera, then take a photo and upload it to the server. The process is actually very simple, but there is a problem.
I hope that the photos taken will not be kept in the photo album of the mobile phone, but completely deleted. They are only available on the server, sf.

Delete after uploading
To take a photo and upload it, you actually have to go through: take a photo and save the photo. Then upload the photo you just saved. If you don’t want to leave traces on your phone, you can delete it after uploading.
