플라스크의 URL로 리디렉션

플라스크의 URL로 리디렉션

---

저는 Python과 Flask를 처음 사용하고 Response.redirect있으며 C #에서 와 같은 작업을 수행하려고합니다 . 즉, 특정 URL로 리디렉션-어떻게해야합니까?

내 코드는 다음과 같습니다.

import os
from flask import Flask

app = Flask(__name__)

@app.route('/')
def hello():
    return 'Hello World!'

if __name__ == '__main__':
    # Bind to PORT if defined, otherwise default to 5000.
    port = int(os.environ.get('PORT', 5000))
    app.run(host='0.0.0.0', port=port)

---

리디렉션을 반환해야합니다.

import os
from flask import Flask,redirect

app = Flask(__name__)

@app.route('/')
def hello():
    return redirect("http://www.example.com", code=302)

if __name__ == '__main__':
    # Bind to PORT if defined, otherwise default to 5000.
    port = int(os.environ.get('PORT', 5000))
    app.run(host='0.0.0.0', port=port)

플라스크 문서에 대한 설명서를 참조하십시오 . 코드의 기본값은 302이므로 code=302생략하거나 다른 리디렉션 코드 (301, 302, 303, 305 및 307 중 하나)로 대체 할 수 있습니다.

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import os
from flask import Flask, redirect, url_for

app = Flask(__name__)

@app.route('/')
def hello():
    return redirect(url_for('foo'))

@app.route('/foo')
def foo():
    return 'Hello Foo!'

if __name__ == '__main__':
    # Bind to PORT if defined, otherwise default to 5000.
    port = int(os.environ.get('PORT', 5000))
    app.run(host='0.0.0.0', port=port)

로부터 플라스크 API 문서 (V 0.10.) :

플라스크. 리디렉션 ( location, code=302, Response=None)

Returns a response object (a WSGI application) that, if called, redirects the client to the target location. Supported codes are 301, 302, 303, 305, and 307. 300 is not supported because it’s not a real redirect and 304 because it’s the answer for a request with a request with defined If-Modified-Since headers.

New in version 0.6: The location can now be a unicode string that is encoded using the iri_to_uri() function.

Parameters:

• location – the location the response should redirect to.
• code – the redirect status code. defaults to 302.
• Response (class) – a Response class to use when instantiating a response. The default is werkzeug.wrappers.Response if unspecified.

I believe that this question deserves an updated: just take a look on the other approaches and make the comparisons.

Here is how you do redirection (3xx) from one url to another in Flask (0.12.2):

#!/usr/bin/env python

from flask import Flask, redirect

app = Flask(__name__)

@app.route("/")
def index():
    return redirect('/you_were_redirected')

@app.route("/you_were_redirected")
def redirected():
    return "You were redirected. Congrats :)!"

if __name__ == "__main__":
    app.run(host="0.0.0.0",port=8000,debug=True)

For other official references, here.

flask.redirect(location, code=302)

Docs can be found here.

Flask includes the redirect function for redirecting to any url. Futhermore, you can abort a request early with an error code with abort:

from flask import abort, Flask, redirect, url_for

app = Flask(__name__)

@app.route('/')
def hello():
    return redirect(url_for('hello'))

@app.route('/hello'):
def world:
    abort(401)

By default a black and white error page is shown for each error code.

The redirect method takes by default the code 302. A list for http status codes here.

---

For this you can simply use the redirect function that is included in flask

from flask import Flask, redirect

app = Flask(__name__)

@app.route('/')
def hello():
    return redirect("www.exampleURL.com", code = 302)

if __name__ == "__main__":
    app.run()

Another useful tip(as you're new to flask), is to add app.debug = True after initializing the flask object as the debugger output helps a lot while figuring out what's wrong.
