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, hashlib
app = 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'])查看资料：flask 不能访问/login_the requested url was not found on the server. if -CSDN博客
flask - The requested URL was not found on the server. If you entered the URL manually please check your spelling and try again - Stack Overflow
