Problem with clicking on the link to download

The backend is written in php.

<code><a href="../CollectionjobAgent
/CollectionJobDashboard/doDownload/
./uploads/collectionjob/0_21111.txt"></a></code>

The interface in the controller is "../CollectionjobAgent/CollectionJobDashboard/doDownload",
Now the backend hopes to get the string ./uploads/collectionjob/0_21111.txt, but it can only read it because of '/' After taking uploads, the collectionjob/0_21111.txt behind is gone. I would like to ask if there is a way to solve this problem.

Just use the query string method.

<a href="../CollectionjobAgent
/CollectionJobDashboard/doDownload?path=./uploads/collectionjob/0_21111.txt"></a>

But due to '/', only uploads can be read. Why?
