注意：TypeError: connect() argument 3 must be str, not int
说明必须是字符串，就是setting.py文件中数据库必须为字符串
出现这个错误是因为’PASSWORD’: 123456, ‘POST’: 3306,设置成这样，应该设置成如下，解决!
DATABASES = {
‘default’: {
‘ENGINE’: ‘django.db.backends.mysql’,
‘NAME’: ‘test01’, # 数据库名
‘USER’: ‘root’,
‘PASSWORD’: ‘123456’,
‘HOST’: ‘localhost’,
‘POST’: ‘3306’,
}
}
