Upload cloud files to WeChat temporary server

My idea is this. input the official number to upload a. jpg file to the temporary server, return mediaID, and display the image to the user. I have found a lot of materials and want to upload local images. it cannot be a Url. Is there a solution? I returned a message like this. input the official number to upload my .jpg to the temporary server, return mediaID, and display the image to the user.

I have found a lot of materials and want to upload local images. it cannot be a Url. Is there a solution?

The message I returned is not multi-text. if you have any idea, please help me. thank you!

If your public account is authenticated, you can call the material management interface.

Can't you save it first?

The built-in api must upload images as local images (however, since they submit images locally, they must still use ajax and so on. you can try to simulate the process on the client and manually send packets)
However, the server slice is only three days old. why do you need to put all your images there?
