我最终实现这一点的方式是通过 PowerShell 调用 StackExchange.Redis 库,因此您需要在方便的地方拥有该 DLL 的副本。在我的部署过程中,我可以访问连接字符串,因此该函数会剥离主机和端口以连接到服务器。这无需打开非 SSL 端口即可工作,并且连接字符串允许管理员访问缓存:
function FlushCache($RedisConnString)
{
# Extract the Host/Port from the start of the connection string (ignore the remainder)
# e.g. MyUrl.net:6380,password=abc123,ssl=True,abortConnect=False
$hostAndPort = $RedisConnString.Substring(0, $RedisConnString.IndexOf(","))
# Split the Host and Port e.g. "MyUrl.net:6380" --> ["MyUrl.net", "6380"]
$RedisCacheHost, $RedisCachePort = $hostAndPort.split(':')
Write-Host "Flushing cache on host - $RedisCacheHost - Port $RedisCachePort" -ForegroundColor Yellow
# Add the Redis type from the assembly
$asm = [System.Reflection.Assembly]::LoadFile("StackExchange.Redis.dll")
# Open a connection
[object]$redis_cache = [StackExchange.Redis.ConnectionMultiplexer]::Connect("$RedisConnString,allowAdmin=true",$null)
# Flush the cache
$redisServer = $redis_cache.GetServer($RedisCacheHost, $RedisCachePort,$null)
$redisServer.FlushAllDatabases()
# Dispose connection
$redis_cache.Dispose()
Write-Host "Cache flush done" -ForegroundColor Yellow
}
