Question

我正在尝试使用nodejs作为运行时从AWS SAM应用程序访问Redis缓存。 Redis服务器正在运行，我可以使用终端进行连接。当sam应用程序尝试访问Redis时，它显示以下错误消息

error: Redis connection to 127.0.0.1:6379 failed - connect ECONNREFUSED 127.0.0.1:6379
at Object._errnoException (util.js:1022:11)
    at _exceptionWithHostPort (util.js:1044:20)
    at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1198:14)

我试图在redis配置文件/usr/local/etc/redis.conf中将bind选项更改为0.0.0.0，protectedMode更改为no，但是仍然面临相同的问题。

import redis, {RedisClient} from 'redis';

export default class LocalCache {
    private  client: RedisClient;
    constructor(host?: string, port?: number ) {
        this.client = redis.createClient(6379, '127.0.0.1');
        this.client.on('connect', function() {
            console.info('Redis client connected');
        });
    }

    public close() {
        return this.client.quit();
    }

    public read(key: string): Promise<string | null> {
        return new Promise ((resolve, reject) => {
            this.client.get(key, (err, res) => {
                if(err){
                    reject(err);
                }
                resolve(res);
            });
        });
    }

    public write(key: string, value: string, time?: number | string, 
           expiryMode?: 'ex' | 'px'): Promise<string|null> {
        return new Promise ((resolve, reject) => {
            if (time) {
                expiryMode = expiryMode || 'ex';
                this.client.set(key, value, expiryMode, 30)
                resolve('success');
            }
            this.client.set(key, value);
            resolve('success');
        });
    }
}

当我在本地运行SAM应用程序时，我希望sam应用程序应该能够访问本地Redis，并允许我在缓存中获取和设置值。
