A tag to download attachment, need to add token, how to do?

as detailed in the title:

current requirements:
for the company"s business, its resources are authorized, such as files and pictures uploaded to the system.

now you need to download the file through a hyperlink on the page, but to download it this way, it is not allowed to pass because it is not recognized by the backend without token.

I have tried to splice token directly after the href attribute, but I still don"t seem to have the permission to download (I don"t know how the backend obtains this token), but even if it can be downloaded, still has some drawbacks. If others open the control and find this link, they will get the token. Won"t it be leaked?

how to solve this problem?

token itself is used for encryption. The backend returns the token to you, and you get the token stitching. Other people know that token can't understand what that string is.

fetch/xmlhttprequest turn to blob to regenerate into a local attachment link to download.

how was the problem of landlord finally solved? now I also encounter the same problem

if it's token, you've already got it on the page.
then you go straight (as follows) 

<a href='wwww.xxxxx.com/?token=asdczlkxcjklfjsdk'>

just splice it.

if it becomes random, you can use token as a variable and bind it to the a tag, which can be changed at any time.

normally, this is a get request. If you make a request like this directly, your backend can take out the parameters in the url and process them to determine whether you should download

.

Js dynamically acquires token, and dynamically splices

when clicking .

Previous: Use document.execCommand ('InsertUnorderedList') to format the outer tag

Next: RequireJS-use r.js to achieve module, project compression and merge, so far I only achieve js compression, can I compress html files?
