加载静态文件,父模板的继承和扩展

1.用url_for加载静态文件

    <script src="{{ url_for('static',filename='js/login.js') }}"></script>
    flask 从static文件夹开始寻找
    可用于加载css, js, image文件

2.继承和扩展

    把一些公共的代码放在父模板中，避免每个模板写同样的内容。base.html
    子模板继承父模板
          {% extends 'base.html’ %}
    3.父模板提前定义好子模板可以实现一些自己需求的位置及名称。block
        <title>{% block title %}{% endblock %}-MIS问答平台</title>
        {% block head %}{% endblock %}
        {% block main %}{% endblock %}
   4. 子模板中写代码实现自己的需求。block
          {% block title %}登录{% endblock %}

首页、登录页、注册页都按上述步骤改写。

from flask import Flask,render_template

app = Flask(__name__)

@app.route('/')
def shouye():
    return render_template('base.html') #跳转首页
@app.route('/denglu/')
def gg():
    return render_template('denglu.html') #跳转登录
@app.route('/zhuche/')
def login():
    return render_template('zhuce.html')#跳转注册

@app.route('/tupian/')
def hh():
    return render_template('22c.html') #跳转图片库
if __name__ == '__main__':
    app.run(debug=True)
