flask页面跳转，两种方法你知道吗

    今天给大家说说flask页面跳转的方法，话不多说直接上代码：

1，redirect()

from flask import Flask

from flask import make_response, request, render_template,redirect,url_for

import setting,json

app = Flask(__name__)

app.config.from_object(setting)

@app.route('/')

def index():

    return render_template("index.html")

users=[]

@app.route('/register',methods = ["Post","Get"])

def register():

    if request.method == "POST":

        username = request.form.get("username")

        password = request.form.get("password")

        repassword = request.form.get("repassword")

        if password == repassword:

            user = {"username":username,"password":password}

            users.append(user)

            print(users)

            return redirect('/') #两次响应 1、302 + location:/ 2、根据location返回需要的值

        else:

            return '密码不一致'

    else:

        return render_template("register.html")

if __name__ == '__main__':

    app.run(host='127.0.0.1', port=5000)

2，url_for() 通过endpoing在route路由中设置别名来进行跳转

from flask import Flask

from flask import make_response, request, render_template,redirect,url_for

import setting,json

app = Flask(__name__)

app.config.from_object(setting)

@app.route('/',endpoint='index')

def index():

    return render_template("index.html")

users=[]

@app.route('/register',methods = ["Post","Get"])

def register():

    if request.method == "POST":

        username = request.form.get("username")

        password = request.form.get("password")

        repassword = request.form.get("repassword")

        if password == repassword:

            user = {"username":username,"password":password}

            users.append(user)

            print(users)

            return redirect(url_for('index')) # url_for

        else:

            return '密码不一致'

    else:

        return render_template("register.html")

@app.route('/test')

def test():

    url = url_for('index')  #路径反向解析

    print(url) #打印出来是'/'

    return 'test'

if __name__ == '__main__':

    app.run(host='127.0.0.1', port=5000)
