我是编程新手，我正在学习本教程：https://www.youtube.com/watch?v=SUC1aTu092w&ab_channel=edureka%21|我试图使用flask和MySQLdb创建一个登录系统，我遇到了这个问题，我很困惑。数据库没有问题，我已经检查过多次了。我正在使用VS代码。错误：werkzeug.routing.BuildError:无法为端点“配置文件”生成url。你是说“索引”吗

在python中，间距是至关重要的。从w/@app.route开始的每一行都应该从最左边开始。我还修复了您的配置文件路径名称


from flask import Flask, render_template, request, redirect, session,  url_for
from flask_mysqldb import MySQL
import MySQLdb

app = Flask(__name__)
app.secret_key = "123456789"

app.config["MYSQL_HOST"] = "localhost"
app.config["MYSQL_USER"] = "root"
app.config["MYSQL_PASSWORD"] = "Root123"
app.config["MYSQL_DB"] = "login"

db = MySQL(app)


@app.route('/', methods=['GET', 'POST'])
def index():
    if request.method == 'POST':
        if 'username' in request.form and 'password' in request.form:
            username = request.form['username']
            password = request.form['password']
            cursor = db.connection.cursor(MySQLdb.cursors.DictCursor)
            cursor.execute("SELECT * FROM logininfo WHERE email= %s AND password= %s", (username,password))
            info = cursor.fetchone()
            if info is not None:
                if info['email'] == username and info['password'] == password:
                    session['loginsuccess'] = True
                    return redirect(url_for('profile'))
            else:
                return redirect(url_for('index'))

    return render_template("login.html")

    
@app.route('/new')
def new_user():
    if request.method == "POST":
        if "one" in request.form and "two" in request.form and "three" in request.form:
            username = request.form['one']
            email = request.form['two']
            password = request.form['three']
            cur = db.connection.cursor(MySQLdb.cursors.DictCursor)
            cur.execute("INSERT INTO login.logininfo(name, password, email)VALUES(%s, %s, %s)", (username, password, email))
            db.connection.commit()
            return redirect(url_for('index'))
    return render_template("register.html")


@app.route('/profile')
def profile():
    if session['loginsuccess'] == True:
        return render_template("profile.html")


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

首先，您没有指定错误，这在这里非常重要。至少我能看到你有这个问题：

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

您必须使用：

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