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
    1. <script src="{{ url_for('static',filename='js/login.js') }}"></script>
    2. flask 从static文件夹开始寻找
    3. 可用于加载css, js, image文件
  2. 继承和扩展
    1. 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
    2. 子模板继承父模板
      1.   {% 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
      1. <title>{% block title %}{% endblock %}-MIS问答平台</title>
      2. {% block head %}{% endblock %}
      3. {% block main %}{% endblock %}
    4. 子模板中写代码实现自己的需求。block
      1.   {% block title %}登录{% endblock %}
  3. 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__)#初始化一个Flask对象，需要传递一个参数__name__

#@app.route('/')      #这是一个装饰器，在函数上面，其作用是做一个URL与视图函数的映射，
                      #http://127.0.0.1:5000/ 去执行hello world（）这个函数
#def hello_world():
    #return 'Hello World!'

@app.route('/')
def index():
    return render_template('1101.html')

@app.route('/shouye/')
def shouye():
    return render_template('shouye.html')

@app.route('/register/')
def register():
    return render_template('31.html')

@app.route('/login/')
def login():
    return render_template('1031.html')

if __name__=='__main__':#当前这个文件作为主程序运行，就会执行这段，作为模板
    app.run(debug=True)            #启动一个web服务器，来监听并接受用户的请求
