[Python] How to make a simple POST function with flask?

I made a local service to learn flask and trying to write some get/post functions. I have no problem with GET but POST just confused me a bit. What I want to do is when some user send his name as POST request service will return as "Hello name". I made some research but everything I saw was so complicated and full of json. I do not want to use json because I just send a string and return a string. Can you guys just help me with that and tell me how can I test that post request on curl? Thanks in advance!

Edit: I tried to write my data in json format as

data = { "name" : " "}


and tried to post like

@app.route("/f",methods=['POST'])
def f():
request_data = request.get_json()
myName = request_data['name']
return (str(myName))


but did not work.
