Flask redirect with same url and different host?

Question

I'm using flask as web server.

Currently, I have a request: http://host-a.com/test1/?a=1&b=2 and I want to redirect to http://host-b.com/test1/?a=1&b=2 and get the response.

Now, I have a lot of such url as test1, test2 and so on. I just want to redirect the host. How to deal with it?

edited: There are many urls need to be redirected, while there are also many urls can't be redirected.

For example: http://host-a.com/test1/?a=1&b=2 need, but http://host-a.com/real1/?a=1&b=2 can't

@YuvalPruss No, you don't understand the problem. There are many urls need to be redirect. — mickeyandkaka, Mar 21 '17 at 08:38

So perhaps this will help you:

from flask import Flask, redirect
app = Flask(__name__)

@app.route('/', defaults={'path': ''})
@app.route('/<path:path>')
def catch_all(path):
    new_path = 'http://host-b.com/' + path
    return redirect(new_path, code=302)

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

Let me try it~. – mickeyandkaka Mar 21 '17 at 08:44
What I do is: 1 get the url, 2 replace the host, 3 get the cookies, 4 send get using requets and get response content. It seems that your code should be worked. Thank you! – mickeyandkaka Mar 21 '17 at 10:08
I don't think this method will forward the parameters a=1 & b=2 – tomcheney Jul 11 '18 at 09:40
You should have a proxy like nginx and handle these redirections over there. – dtc Jan 30 '23 at 17:31
