我认为这个问题值得更新。只要和其他方法比较一下。

以下是如何在Flask(0.12.2)中从一个url重定向到另一个url:

#!/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)

你可以这样用:

import os
from flask import Flask

app = Flask(__name__)

@app.route('/')
def hello():
     # Redirect from here, replace your custom site url "www.google.com"
    return redirect("https://www.google.com", code=200)

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)

从Flask API文档(v. 2.0.x):

flask.redirect(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.

这很容易，如果你只是想重定向到一个url没有任何状态码或类似的东西，你可以简单地说

from flask import Flask, redirect

app = Flask(__name__)

@app.route('/')
def redirect_to_link():
    # return redirect method, NOTE: replace google.com with the link u want
    return redirect('https://google.com')

这里是Flask Docs的链接，可以获得更多的解释

为此，您可以简单地使用flask中包含的重定向函数

from flask import Flask, redirect

app = Flask(__name__)

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

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

另一个有用的技巧(因为你是flask的新手)是在初始化flask对象后添加app.debug = True，因为调试器输出在找出错误时很有帮助。

#!/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)
