Python: How to get multiple variables from a URL in Flask?

Question

I am trying to get a few arguments from a URL in Flask. After reading this SO answer, I thought I could do it like this:

@app.route('/api/v1/getQ/', methods=['GET'])
def getQ(request):
    print request.args.get('a')
    print request.args.get('b')
    return "lalala"

But when I visit /api/v1/getQ/a=1&b=2, I get TypeError: getQ() takes exactly 1 argument (0 given). I tried other urls like /api/v1/getQ/?a=1&b=2and /api/v1/getQ?a=1&b=2, but to no avail.

Does anyone know what I'm doing wrong here? All tips are welcome!
