Get Query String As Function Parameters On Flask

Is there a way to get query string as function parameters on flask? For example, the request will be like this. http://localhost:5000/user?age=15&gender=Male And hope the code

Solution 1:

If you are willing to write a decorator, anything is possible:

from functools import wraps

defextract_args(*names, **names_and_processors):
    user_args = ([{"key": name} for name in names] +
        [{"key": key, "type": processor}
            for (key, processor) in names_and_processors.items()])

    defdecorator(f):
        @wraps(f)defwrapper(*args, **kwargs):
            final_args, final_kwargs = args_from_request(user_args, args, kwargs)
            return f(*final_args, **final_kwargs)
        return wrapper
    return decorator iflen(names) < 1ornotcallable(names[0]) else decorator(names[0])

defargs_from_request(to_extract, provided_args, provided_kwargs):
    # Ignoring provided_* here - ideally, you'd merge them# in whatever way makes the most sense for your application
    results = {}
    for arg in to_extract:
        result[arg["key"]] = request.args.get(**arg)
    return provided_args, results

Usage:

@app.route("/somewhere")
@extract_args("gender", age=int)
def somewhere(gender, age):
    return jsonify(gender=gender, age=age)

Solution 2:

Flask views themselves do not have obligatory args. You can write:

from flask import request

@app.route("/user")
def getUser():
    age = request.args.get('age')
    gender = request.args.get('gender')
