[Flask]学习Flask第三天笔记总结

 from flask import Flask,render_template,request

 from others import checkLogin

 app = Flask(__name__)

 #从templates里引用index.html

 #return render_template("index.html")

 @app.route('/')

 def index():

     return '''<form action="/login" method="post">

                 <input type="text" name="username" value=""><br >

                 <input type="text" name="password" value="">

                 <input type="submit" value="submit">

                 </form>

            '''

 @app.route('/login',methods=['GET','POST'])

 def login():

     if request.method == 'POST':

         #checkLogin是自己写的使用mysql返回账号密码正确性,返回True/False

         #request.form['username'] 从表单获取username的值,password同

         #获取get参数的是 request.args.get['keyword']获取keyword参数值

         if checkLogin(request.form['username'],request.form['password']):

             return 'Hello '+request.form['username']

         else:return 'Fail'

 if __name__ == '__main__':

     #debug显示信息,host绑定ip,port 绑定端口

     app.run(debug=True)

引用模板,并在模板显示信息

 from flask import Flask,render_template,request

 app = Flask(__name__)

 @app.route('/user/<name>')

 def index(name):

     return render_template('user.html',username=name)

模板 user.html

  <ul>

      {% if username %}

          <li>{{ username }}</li>

      {% endif %}

  </ul>

用之前写的爬行wooyun镜像站实例(部分代码)记录:

 from flask import Flask,render_template,request

 from wooyun import wooyunfilter

 app = Flask(__name__)

 @app.route('/',methods=['GET'])

 def index():

     return render_template('index.html')

 @app.route('/search',methods=['GET'])

 def search():

     keyword = request.args.get('keyword')

     title = keyword

     obj = wooyunfilter(keyword,'')

     a = obj.search()

     pageZip = zip(a[0],a[1],a[2],a[3])

     return render_template('wooyun.html',title=title,zip=pageZip)

 if __name__ == '__main__':

     app.run(debug=True)

wooyun.html主要代码:

 <ul>

        {% for hrefs,times,titles,types in zip %}

        <li><strong>{{ times }}</strong><a href="{{ url_for('apear',next=hrefs) }}" target="_blank">{{ '   '+titles }}</a><span>{{ '   '+types }}</span></li>

        {% endfor %}

 </ul>
