数据库login.py和register.py错误显示404文件未找到并且不起作用

问题描述 投票：0回答：1

我想连接到数据库并进行正常的登录和注册过程

  • 注册的详细信息应存储在 data.db 中，并且可以通过登录进行检索以用于登录目的，这就是我想要的，但由于我对所有数据库和内容都是新手，所以有点难

This is Directories for all

这是我的注册 html -

这是我的register.py 文件

from flask import Flask, render_template, request, jsonify
import sqlite3

app = Flask(__name__)

@app.route('/signup/Register/register', methods=['GET', 'POST'])
def register():
    if request.method == 'POST':
        username = request.form['username']
        email = request.form['email']
        password = request.form['password']

        conn = sqlite3.connect('../users.db')
        cursor = conn.cursor()

        try:
            cursor.execute('INSERT INTO users (username, email, password) VALUES (?, ?, ?)', (username, email, password))
            conn.commit()
            conn.close()
            return jsonify({'success': True, 'message': 'Registration successful'})
        except sqlite3.IntegrityError:
            conn.close()
            return jsonify({'success': False, 'message': 'Username or email already exists'})
    else:
        return render_template('signup/Register/index_signup.html')

if __name__ == '__main__':
    app.run(debug=True)

和login.py文件

from flask import Flask, request, jsonify, redirect
import sqlite3

app = Flask(__name__)

@app.route('/login', methods=['POST'])
def login():
    email = request.form['email']
    password = request.form['password']

    conn = sqlite3.connect('users.db')
    cursor = conn.cursor()

    cursor.execute('SELECT * FROM users WHERE email=? AND password=?', (email, password))
    user = cursor.fetchone()

    conn.close()

    if user:
        # Redirect to a success page
        return redirect('/success')
    else:
        # Redirect to a failure page
        return redirect('/failure')

if __name__ == '__main__':
    app.run(debug=True)

我尝试运行python文件，在询问GPT后它给出了404文件未找到的错误，它说很可能是@app.route(/register)，问题出在哪里，但我是flask的新手，不知道是什么这个

你需要了解路由、url等基本概念

我建议查看flask官方文档中的教程。 （https://flask.palletsprojects.com/en/3.0.x/tutorial/）

我会处理您想要做的事情，例如通过提交表单进行经典用户注册和登录。

这不是您问题的直接答案。 然而，它最终会得到回报。 不要认为阅读文档是浪费时间！！
