我正在构建一个 Web 应用程序并尝试使用 redirect() 函数链接两个 html。但是，当我单击“提交”按钮时，login.html 不会重定向到 success.html（即浏览器仍在 login.html 中）下面是我的python代码：from flask import Flask, redirect, url_for, render_template, request, abortapp = Flask(__name__)@app.route('/')def index(): return render_template('login.html')@app.route('/login',methods = ['POST', 'GET'])def login(): if request.method == 'POST': if request.form['username'] == 'admin': return redirect(url_for('success')) else: abort(401) else: return redirect(url_for('index'))@app.route('/success', methods = ['POST', 'GET'])def success(): return 'logged in successfully'if __name__ == '__main__': app.run(debug = True)还有 html 代码：<html> <body> <form action = "login" method = "post"> <p>Enter Name:</p> <p><input type = "text" name = "username" /></p> <p><input type = "submit" value = "submit" /></p> </form> </body></html>

您的字段名称在 html 和视图函数中不匹配。更改name = "nm"为name = "username"：
<html>
<body>
<form action = "login" method = "post">
<p>Enter Name:</p>
<p><input type = "text" name = "username" /></p>
<p><input type = "submit" value = "submit" /></p>
</form>
</body>
</html>
