Question

我正在尝试创建一个用户注册页面来练习Flask。我设法使所有工作正常进行，但是我唯一遇到的问题是数据库。每当我在注册页面中输入虚拟文本并按提交时，都会出现此错误：

MySQLdb._exceptions.OperationalError: (1045, "Access denied for user 'root'@'localhost' (using password: YES)")

我尝试了类似的解决方案，但无济于事。我尝试过刷新特权等，但我真的不太明白这是怎么回事。

到目前为止，这是我的代码：

from flask import Flask
from flask import render_template
from flask import flash
from flask import redirect
from flask import url_for
from flask import session
from flask import logging
from flask import request
from flask_mysqldb import MySQL
from wtforms import Form, StringField, TextAreaField, PasswordField, validators
from passlib.hash import sha256_crypt

app = Flask(__name__)

# Config MySQL
app.config['MYSQL_HOST'] = 'localhost'
app.config['MYSQL_USER'] = 'root'
app.config['MYSQL_PASSWORD'] = 'localhost'
app.config['MYSQL_DB'] = 'localhost'
app.config['MYSQL_CURSORCLASS'] = 'DictCursor'

# init MYSQL
mysql = MySQL(app)


@app.route('/')
def index():
    return render_template('home.html')


@app.route('/home')
def home():
    return render_template('home.html')


class RegisterForm(Form):
    name = StringField('Name', [validators.Length(min=1, max=50)])
    username = StringField('Username', [validators.Length(min=4, max=25)])
    email = StringField('Email', [validators.Length(min=6, max=50)])
    reason_for_joining = StringField('Why Do You Want To Join?', [
        validators.Length(min=50, max=280)
    ])
    password = PasswordField('Password', [validators.DataRequired(), validators.EqualTo(
        'confirm', message='Passwords do not match.')])
    confirm = PasswordField('Confirm Password')


@app.route('/register', methods=['GET', 'POST'])
def register():
    form = RegisterForm(request.form)
    if request.method == 'POST' and form.validate():
        name = form.name.data
        email = form.email.data
        username = form.username.data
        reason_for_joining = form.reason_for_joining.data
        password = sha256_crypt.encrypt(str(form.password.data))

        # Create cursor
        cur = mysql.connection.cursor()

        # Run query
        cur.execute("INSERT INTO users(name, email, username, reason_for_joining, password) VALUES(%s, %s, %s, %s)",
                    (name, email, username, reason_for_joining, password))

        # Commit to DB
        mysql.connection.commit()

        # Close connection
        cur.close()

        # Message that shows if user registered successfully
        flash("Your registration will be reviewed.", "success")

        redirect(url_for("index"))
        return render_template('register.html', form=form)
    return render_template('register.html', form=form)


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

这是我得到的回溯错误： https://imgur.com/psKFYbU

如果遇到错误，例如错误1044（42000）：尝试创建数据库时，拒绝用户'your_name'@'localhost'对数据库'menagerie'的访问，这意味着您的用户帐户没有必要的访问权限这样做的特权。与管理员讨论此问题，或参阅第6.2节“Access Control and Account Management”。
