为什么启用保持活动时ioredis客户端超时?

[英]Why does ioredis client timeout when keep-alive is enabled?

I have been getting the following error, when my script stays idle for sometime.当我的脚本闲置一段时间时,我收到以下错误。 I cannot understand the reason for this.我无法理解这样做的原因。

    error: [ioredis] Unhandled error event: 
error: Error: read ECONNRESET
    at TCP.onStreamRead (internal/stream_base_commons.js:111:27) 
error: [ioredis] Unhandled error event
error: Error: read ETIMEDOUT
    at TCP.onStreamRead (internal/stream_base_commons.js:111:27) 

I initialize my redis client as :我将我的 redis 客户端初始化为:

let redis = require("ioredis");
redis = Promise.promisifyAll(redis);

const redis = new redis({
   host: "my hostname",
   port: 6379,
   password: "some password"
});

and I am using ioredis client .我正在使用ioredis 客户端

Does anyone know the reason for this?有谁知道这是什么原因? The keep-alive is already enabled by default as suggested here https://github.com/luin/ioredis/blob/master/API.md按照此处的建议,默认情况下已启用保持活动状态https://github.com/luin/ioredis/blob/master/API.md

I want the client to never timeout and reconnect if the timeout occurs.我希望客户端永远不会超时并在超时发生时重新连接。 I am using Redis service by azure.我正在使用 azure 的 Redis 服务。

We have an entire document that covers this topic: Troubleshoot Azure Cache for Redis timeouts我们有一个涵盖此主题的完整文档: 对 Azure Redis 缓存超时进行故障排除

If using the StackExchange.Redis Client the best practice of using the following pattern is suggested:如果使用 StackExchange.Redis 客户端,建议使用以下模式的最佳实践:

private static Lazy<ConnectionMultiplexer> lazyConnection = new Lazy<ConnectionMultiplexer>(() =>
{
return ConnectionMultiplexer.Connect("cachename.redis.cache.windows.net,abortConnect=false,ssl=true,password=...");
});
public static ConnectionMultiplexer Connection
   {
get
{
return lazyConnection.Value;
}
}

In the case of ioredis, you can set a client property: [options.lazyConnect]在ioredis的情况下,你可以设置一个客户端属性: [options.lazyConnect]

You will also want to look at any retry methods available with your client.您还需要查看客户端可用的任何重试方法。 I hope this helps.我希望这有帮助。
