本文实例讲述了python flask框架实现重定向功能。分享给大家供大家参考，具体如下：

flask 重定向:

from flask import *app = Flask(__name__)@app.route('/')def index():  return redirect(url_for('login'))@app.route('/login')def login():    return render_template('login.html')if __name__ == '__main__':  app.run(host='0.0.0.0',port=6001,debug=True)[oracle@node01 ~]$ curl 192.168.137.1:6001<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN"><title>Redirecting...</title><h1>Redirecting...</h1><p>You should be redirected automatically to target URL: <a href="/login" rel="external nofollow" rel="external nofollow" >/login</a>. If not click the link.[oracle@node01 ~]$use Net::SMTP;use LWP::UserAgent;use HTTP::Cookies;use HTTP::Headers;use HTTP::Response;use Encode;use Switch;use File::Temp qw/tempfile/;use HTTP::Date qw(time2iso str2time time2iso time2isoz);use Data::Dumper;my $CurrTime = time2iso(time());my $ua = LWP::UserAgent->new;$ua->timeout(10);$ua->env_proxy;my $now     = time();$ua->agent('Mozilla/5.0');my $cookie_jar = HTTP::Cookies->new(  file      => 'lwp_cookies.txt',  autosave    => 1,  ignore_discard => 1);$ua->cookie_jar($cookie_jar);my $response = $ua->get("http://127.0.0.1:6001/");if ($response->is_success) {  print encode("gbk",decode("utf8",Dumper($response)));  $r=$response->content;  $str=encode("gbk",decode("utf8","$r"));  print $str."/n";}

perl 演示:
