  • Flask入门之开发简单登陆界面

    涉及知识点:

    • render_template()
    • redirect():注意def的函数不要使用这个Python关键字
    • url_for():可以传参数给动态路由
    • 动态路由
     1 # Sample.py
     2 
     3 from flask import Flask, render_template, url_for, request, redirect
     4 
     5 app = Flask(__name__)
     6 
     7 @app.route('/')
     8 def hello_world():
     9     return 'hello,world'
    10 
    11 @app.route('/user/<username>', methods=['POST', 'GET'])
    12 def user(username):
    13     return 'Hello,%s' % username
    14 
    15 @app.route('/user/login')
    16 def login():
    17     return render_template('login.html')
    18 
    19 @app.route('/user/redirect', methods=['POST'])
    20 def redirect_to_new_url():
    21     username = request.form['username']
    22     return redirect(url_for('user',username=username))
    23 
    24 if __name__ == '__main__':
    25     app.run(debug=True)

    / template/

     1 #login.html
     2 <!DOCTYPE html>
     3 <html lang="en">
     4 <head>
     5     <meta charset="UTF-8">
     6     <title>请登陆会员账号</title>
     7 </head>
     8 <body>
     9     <h2>请登陆您的会员账号</h2>
    10     <form action='{{ url_for('.redirect_to_new_url') }}' method="POST">
    11         <table>
    12             <tr>
    13                 <td>会员名:</td>
    14                 <td><input type="text" name='username' placeholder="Username" value="BIKMIN"></td>
    15             </tr>
    16             <tr>
    17                 <td>密码:</td>
    18                 <td><input type="password" name='password' placeholder="Password"></td>
    19             </tr>
    20             <tr>
    21                 <td><input type="submit" value="登陆"></td>
    22             </tr>
    23         </table>
    24     </form>
    25 </body>
    26 </html>

     测试运行
