解决redis ResponseError: [PROXY] unsupported command select

>>> from django_redis import get_redis_connection

>>> r.set('test', 1)

今天redis 加入认证机制，并采用proxy链接，先看django的caches 配置：

CACHES = {
     
    "default": {
     
        "BACKEND": "django_redis.cache.RedisCache",
        "LOCATION": "redis://ip:6379/0",
        "OPTIONS": {
     
            "CLIENT_CLASS": "django_redis.client.DefaultClient",
            "PASSWORD": "pwd",
        }
    }
}

当我将 LOCATION 的 redis库配置为0库时，不会报错，当配置为1~15库时就会报错，所以总结为proxy做了redis后面所有库的整合，默认就是0库。
