405 when submitting form to Flask app

Question

I'm trying to create a webpage in html in which a user have to input a url into a textfield.

<form name="submitURL" method ="post">
<input type="text" name="url_target">
<button type="submit">submit</button>

When the user press the submit button a python script should intercept the data inserted by the user and pass it to another function inside this script.

Python script:

from flask import Flask, render_template, request

app = Flask(__name__)

@app.route('/')
def indhtml() :
   return render_template('index.html')

@app.route('/index.html', methods = ['POST'])
def result():
    result = request.form('url_target')
    link = result.link
    print (link)
    return

if __name__ == '__main__' :
    app.run(debug = True)

the first render is fine and i can see the index.html page, but when i insert something in the textfield appears the error HTTP 405.

Do you have any suggestion for that? :( Thanks!

您的函数result()返回任何内容。

You forgot action="{{ url_for('result') }}" in your <form> tag, so you are submitting the form to the same page, which is not accepting POST requests.

Additionally, request.form is dict-like, so you need [] and not () to access it. link = result.link is going to fail too because there is no way that link attribute exists on the string you get from request.form ...
