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)
