怎么在python中利用flask框架实现一个重定向功能

本篇文章为大家展示了怎么在python中利用flask框架实现一个重定向功能，内容简明扼要并且容易理解，绝对能使你眼前一亮，通过这篇文章的详细介绍希望你能有所收获。

flask 重定向:

fromflaskimport*
app=Flask(__name__)
@app.route('/')
defindex():
returnredirect(url_for('login'))
@app.route('/login')
deflogin():
returnrender_template('login.html')
if__name__=='__main__':
app.run(host='0.0.0.0',port=6001,debug=True)
[oracle@node01~]$curl192.168.137.1:6001
<!DOCTYPEHTMLPUBLIC"-//W3C//DTDHTML3.2Final//EN">
<title>Redirecting...</title>
<h2>Redirecting...</h2>
<p>YoushouldberedirectedautomaticallytotargetURL:<ahref="/login"rel="externalnofollow"rel="externalnofollow">/login</a>.Ifnotclickthelink.[oracle@node01~]$
useNet::SMTP;
useLWP::UserAgent;
useHTTP::Cookies;
useHTTP::Headers;
useHTTP::Response;
useEncode;
useSwitch;
useFile::Tempqw/tempfile/;
useHTTP::Dateqw(time2isostr2timetime2isotime2isoz);
useData::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($response->is_success){
printencode("gbk",decode("utf8",Dumper($response)));
$r=$response->content;
$str=encode("gbk",decode("utf8","$r"));
print$str."\n";
}

perl 演示:
