我想做的是类似于回应。重定向作为在c# -即:重定向到一个特定的URL -我怎么去做这个?
这是我的代码:
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)
当前回答
#!/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)
请查看文档中的示例。

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.
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。
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
flask.redirect(location, code=302)
文档可以在这里找到。
#!/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)
