篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了11.3相关的知识,希望对你有一定的参考价值。

  1. 新建Flask项目。
  2. 设置调试模式。
  3. 理解Flask项目主程序。
  4. 使用装饰器,设置路径与函数之间的关系。
  5. 使用Flask中render_template,用不同的路径,返回首页、登录员、注册页。
  6. 用视图函数反转得到URL,url_for(‘login’),完成导航里的链接。
    flask代码:
    from flask import Flask,render_template
    
    app = Flask(__name__)
    
    
    @app.route(\'/\')
    def shouye():
        return render_template(\'shouye.html\')
    @app.route(\'/tt\')
    def tt():
        return render_template(\'tt.html\')
    @app.route(\'/zhuce\')
    def zhuce():
        return render_template(\'zhuce.html\')
    
    if __name__ == \'__main__\':
        app.run(debug=True)

     

  7. 首页代码:
    <!DOCTYPE html>
    <html lang="en">
    <head>
        <meta charset="UTF-8">
        <title>网易考拉</title>

            .li{
                background-color: blanchedalmond ;

            .ziti{
                font-family: "Adobe 仿宋 Std R";font-size: small;
            }
            .zix{
                font-family: "Adobe 黑体 Std R";font-size: medium;
            }
