POST request is not being directed to POST route in Flask

Question

I am developing a web app with Flask.
I have two routes:

@app.route("/<random_id>", methods = ['GET'])
def random_url(random_id):
    return "GET"

@app.route("/<random_id>", methods = ['POST'])
def random_url_post(random_id):
    return "POST"

When I access it with GET, I received "GET" but when I tried with POST request, it failed:

root@ubuntu:~# curl http://localhost:1337/a
GET
root@ubuntu:~# curl -xPOST http://localhost:1337/a
curl: (5) Could not resolve proxy: POST
curl: (5) Could not resolve proxy: POST

What can be a reason for that?

Answer 1

-x is a proxy arg. You should use -X in uppercase
