Trailing slash in Flask route

Question

Take for example the following two routes.

app = Flask(__name__)

@app.route(\"/somewhere\")
def no_trailing_slash():
    #case one

@app.route(\"/someplace/         


        

Answer 1

You are on the right tracking with using strict_slashes, which you can configure on the Flask app itself. This will set the strict_slashes flag to False for every route that is created

app = Flask('my_app')
app.url_map.strict_slashes = False

Then you can use before_request to detect the trailing / for a redirect. Using before_request will allow you to not require special logic to be applied to each route individually

@app.before_request
def clear_trailing():
    from flask import redirect, request

    rp = request.path 
    if rp != '/' and rp.endswith('/'):
        return redirect(rp[:-1])
