在过去的一个小时里，我一直在尝试使请求标签在烧瓶中工作..
这是我在 server.py 中的代码：
@app.route('/login', methods=['post'])
def receive_data():
user = request.form['username']
password = request.form['password']
return f'<h1>name:{user} password:{password}</h1>'
在index.html中它：
<form action="{{ url_for('receive_data'}}" method="POST">
<label>Name</label>
<input type="text" placeholder="name" name="username">
<label>Password</label>
<input type="text" placeholder="password" name="password">
<button type="submit">Ok</button>
</form>
I also tried the request.form.get('username')but it returns none
确保导入
requestfrom flask import Flask, request
呵呵是server.py:
from flask import Flask, request, render_template
app = Flask(__name__)
@app.route('/')
def index():
return render_template('index.html')
@app.route('/login', methods=['POST'])
def receive_data():
user = request.form.get('username')
password = request.form.get('password')
if user and password:
return f'<h1>Name: {user}, Password: {password}</h1>'
else:
return '<h1>Missing username or password</h1>', 400
if __name__ == '__main__':
app.run(debug=True)
这是HTML：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Login Page</title>
</head>
<body>
<form action="{{ url_for('receive_data') }}" method="POST">
<label for="username">Name:</label>
<input type="text" id="username" name="username" placeholder="Enter your name">
<br>
<label for="password">Password:</label>
<input type="password" id="password" name="password" placeholder="Enter your password">
<br>
<button type="submit">Login</button>
</form>
</body>
</html>
不要忘记安装 Flask 😇！
pip install Flask
