开始Flask项目

  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：

    <!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>首页</title>
    <link rel="stylesheet" type="text/css" href="../static/css/base.css">
     <link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">
    <script src="../static/js/base.js"></script>

            <button type="button" class="btn btn-default navbar-btn">导航栏</button>
             </form>
            <ul class="nav navbar-nav navbar-right" id="myBody">
           <li ><img class="tupian" id="myOnOff" onclick="myswitch()" src="../static/image/sun.png"></li>
                <li><a href="{{ url_for('sy') }}"><span class="glyphicon glyphicon-user"></span> 首页</a></li>
