[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>
