Getting Flask Request Data

Bit of a noob with Flask, sorry.

My application is collecting the value from a drop down then POSTing that string to my flask function. I can (sort of) get at the data by using:

@app.route("/lookupmember", methods=["POST"])
def lookupmember():
    member = request.data
    print(member)
    return member

Interestingly though when I print the value of "member" out there in the python function I see something like:

127.0.0.1 - - [19/Oct/2018 18:15:31] "POST /lookupmember HTTP/1.1" 200 - b'john doe'

Whats the b' before the name 'john doe'?

When I console.log the same value after passing it back in the Ajax caller only the name is printed in the browser console.

I reckon the b' part might be a key or identifier applied by flask? If so, it seems reasonable that there would be a way to use that to parse to get to just the name?

If member is of type bytes, then you should convert it to a string using the decode() function. Then convert that result to JSON so that you can read it in your browser using the jsonify function:

@app.route("/lookupmember", methods=["POST"])
def lookupmember():
    member = request.data
    print(member)
    return jsonify(member.decode("utf-8"))
