Get multiple request params of the same name

Question

My problem is that with the given code:

from flask import Flask, request

app = Flask(__name__)

@app.route(\"/\")
def hello():
    return str(request.values         


        

Answer 1

Another option is to use a flat json structure with request.args. Because sometimes you simply do not know the parameter beforehand and you cannot use .getlist().

arguments = request.args.to_dict(flat=False)

# Get a specific parameter
params = arguments.get('param')
print(params)

# Get all the parameters that have more than one value
for field, values in arguments.items():
    if len(values) > 1:
        print(values)
