Mysql 错误（1045，“拒绝用户访问”&“x27；用户”&“x27”；172.27.0.3&“x27；（使用密码：是）”）

在尝试使用docker连接mysql时，我得到了以下日志。我如何解决这个问题

Docker编写文件 设置.py

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'default_schema',
        "USER": 'admin',
        "PASSWORD": "test",
        'HOST': 'db',
        'PORT': '3307',
    }
}

不确定，但这可能会回答您的问题：如果凭据正确，mysql.user表中是否存在提到的主机“172.27.0.3”？我的文章解释了其他原因

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'default_schema',
        "USER": 'admin',
        "PASSWORD": "test",
        'HOST': 'db',
        'PORT': '3307',
    }
}
