[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>
