python实现Flask POST Demo
数据处理逻辑
from flask import Flask, requestapp = Flask(__name__)@app.route('/', methods=['POST'])
def index():username = request.form['username']password = request.form['password']if username == "Jhon" and password == "1":return f"<html><body>Welcome {username}</body></html>"else:return f"<html><body>Welcome!</body></html>"if __name__ == '__main__':app.run(debug=True)
前端代码
<!DOCTYPE html>
<html lang="en">
<head><meta charset="UTF-8"><title>GET and POST</title>
</head>
<body><form action = "http://localhost:5000" method = "post"><table><tr><td>Name</td><td><input type ="text" name ="username"></td></tr><tr><td>Password</td><td><input type ="password" name ="password"></td></tr><tr><td><input type = "submit"></td></tr></table></form>
</body>
</html>
两个文件在同目录下，运行py文件即可。
