[FIXED] Redirecting in Flask with path from url

Issue

I am running into a problem trying to redirect in Flask using the following:

 @views.route('/dash_monitoring/<path:url>')
 @login_required
 def monitoring_page(url):
     return redirect("/home/dash_monitoring/{}".format(url))

The url in <path:url> is in the format https://somesite.com/detail/?id=2102603 but when I try to print it in the function, it prints https://somesite.com/detail only without the id part,so it obviously redirects to /home/dash_monitoring/https://somesite.com/detail instead of /home/dash_monitoring/https://somesite.com/detail/?id=2102603.

What should I do so it keeps the id part and redirects to the right url?

Solution

You can use request.url and imply string manipulation:

@views.route('/dash_monitoring/<path:url>')
@login_required
def monitoring_page(url):
    parsed_path = request.url.split('/dash_monitoring/')[1]
    #return the parsed path
    return redirect("/home/dash_monitoring/{}".format(parsed_path))

Alternatively, you can iterate through request.args for creating query string and construct path with args

@views.route('/dash_monitoring/<path:url>')
@login_required
def monitoring_page(url):
    query_string = ''
    for arg,value in request.args.items():
        query_string+=f"{arg}={value}&"
    query_string=query_string[:-1] # to remove & at the end
    path=f"{path}?{query_string}"
    #return the parsed path
    return redirect(f"/home/dash_monitoring/{path}")

I hope this helps :)
