python-Flask搭建简易登录界面

使用Flask框架搭建一个简易的登录界面，登录成功获取token数据

1 搭建简易登录界面

代码如下

from flask import Flask, jsonify
from flask import  request
import time, hashlibapp = Flask(__name__)login_html = '''
<html> 
<head>
<title>Login Page</title>
</head>
<body>
<form action="/doLogin" method="post">Account:<input type="text" name="account"><br>PassWord:<input type="text" name="password"><br>
<input type="submit" value="Submit">
<input type="reset" value="reset">
</form>
</body>
</html>
'''@app.route('/', methods=['GET', 'POST'])
def login_index():return login_html@app.route('/doLogin', methods=['POST'])
def do_login():if request.method == 'POST':account = request.form['account']password = request.form['password']if account == 'freePHP' and password == '123456':timestamp = time.time()prev_str = account + password +str(timestamp)token = hashlib.md5(prev_str.encode(encoding='UTF-8')).hexdigest()json_data = [{'token': token, 'user_id':101}];return jsonify({'data':json_data, 'result':True, 'errorMsg':''})else:return jsonify({'data':[], 'result':True, 'errorMsg':'Account and password is not matched'})if __name__ ==  '__main__':app.run(debug=True)

启动

浏览器访问http://127.0.0.1:5000

登录账户密码正确，获取token

登录账户密码输入错误：

后续操作：登录界面连接上数据库，判断是否能登录等一系列操作

注意点

问题：在进行提交密码时遇到Not Found，经查询是登录路由编写错误

改为：@app.route('/doLogin', methods=['POST'])
