An example of ajax that uploads an image to the background and reads it,

You can upload images in either of the following ways:

1. fileReader can parse the image into a base64 format, which is simple and rude.

2. canvas can re-draw an image. You can first put the blob of the obtained image into the canvas, regenerate the image with a width and transparency, and then convert it to the corresponding type and upload it to the background, currently, png and jpeg formats are supported.

The example of uploading images to the backend and reading the above ajax is all the content shared by Alibaba Cloud. I hope you can give us a reference and support for the customer's house.
