篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了开始Flask项目相关的知识,希望对你有一定的参考价值。
- 新建Flask项目。
- 设置调试模式。
- 理解Flask项目主程序。
- 使用装饰器,设置路径与函数之间的关系。
- 使用Flask中render_template,用不同的路径,返回首页、登录员、注册页。
- 用视图函数反转得到URL,{{url_for(‘login’)}},完成导航条里的链接
from flask import Flask,render_template app = Flask(__name__) @app.route(\'/\') def sy(): return render_template(\'sy.html\') @app.route(\'/dl/\') def dl(): return render_template(\'dl.html\') @app.route(\'/zc/\') def zc(): return render_template(\'zc.html\') if __name__ == \'__main__\': app.run(debug=True)
反转:
