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";
}
