How do you access the query string in Flask routes?

from flask import request@app.route('/data')def data():    # here we want to get the value of user (i.e. ?user=some-value)    user = request.args.get('user')

The full URL is available as request.url, and the query string is available as request.query_string.decode().

Here's an example:

from flask import request@app.route('/adhoc_test/')def adhoc_test():    return request.query_string

To access an individual known param passed in the query string, you can use request.args.get('param'). This is the "right" way to do it, as far as I know.

ETA: Before you go further, you should ask yourself why you want the query string. I've never had to pull in the raw string - Flask has mechanisms for accessing it in an abstracted way. You should use those unless you have a compelling reason not to.

I came here looking for the query string, not how to get values from the query string.

request.query_string returns the URL parameters as raw byte string (Ref 1).

Example of using request.query_string:

from flask import Flask, requestapp = Flask(__name__)@app.route('/data', methods=['GET'])def get_query_string():    return request.query_stringif __name__ == '__main__':    app.run(debug=True)

Output:
