 1 from flask import Flask,render_template,request
2 from others import checkLogin
3 app = Flask(__name__)
4
5 #从templates里引用index.html
6 #return render_template("index.html")
7 @app.route('/')
8 def index():
9 return '''<form action="/login" method="post">
10 <input type="text" name="username" value=""><br >
11 <input type="text" name="password" value="">
12 <input type="submit" value="submit">
13 </form>
14 '''
15
16 @app.route('/login',methods=['GET','POST'])
17 def login():
18 if request.method == 'POST':
19 #checkLogin是自己写的使用mysql返回账号密码正确性,返回True/False
20 #request.form['username'] 从表单获取username的值,password同
21 #获取get参数的是 request.args.get['keyword']获取keyword参数值
22 if checkLogin(request.form['username'],request.form['password']):
23 return 'Hello '+request.form['username']
24 else:return 'Fail'
25
26 if __name__ == '__main__':
27 #debug显示信息,host绑定ip,port 绑定端口
28 app.run(debug=True)

 

引用模板,并在模板显示信息

1 from flask import Flask,render_template,request
2 app = Flask(__name__)
3
4 @app.route('/user/<name>')
5 def index(name):
6 return render_template('user.html',username=name)

模板 user.html

1  <ul>
2 {% if username %}
3 <li>{{ username }}</li>
4 {% endif %}
5 </ul>

用之前写的爬行wooyun镜像站实例(部分代码)记录:

 1 from flask import Flask,render_template,request
2 from wooyun import wooyunfilter
3 app = Flask(__name__)
4
5
6 @app.route('/',methods=['GET'])
7 def index():
8 return render_template('index.html')
9
10 @app.route('/search',methods=['GET'])
11 def search():
12 keyword = request.args.get('keyword')
13 title = keyword
14 obj = wooyunfilter(keyword,'')
15 a = obj.search()
16 pageZip = zip(a[0],a[1],a[2],a[3])
17 return render_template('wooyun.html',title=title,zip=pageZip)
18
19 if __name__ == '__main__':
20 app.run(debug=True)

wooyun.html主要代码:

1 <ul>
2 {% for hrefs,times,titles,types in zip %}
3 <li><strong>{{ times }}</strong><a href="{{ url_for('apear',next=hrefs) }}" target="_blank">{{ ' '+titles }}</a><span>{{ ' '+types }}</span></li>
4 {% endfor %}
5
6 </ul>
