简单的 redis 分布式锁

## 安装

```bash

npm i -S @wenye123/redis-lock

```

## 使用例子

```javascript

import redisLock from "@wenye123/redis-lock";

import Redis from "ioredis";

const redis = new Redis({

  host: "127.0.0.1",

  port: 6379,

});

const rlock = new redisLock({

  client: redis,

  keyPrefix: "bm:",

});

const lockName = "tlock";

// 获取锁标志，null则表示获取失败

const identifier = await rlock.acquireLock(lockName);

// 释放锁

await rlock.releaseLock(lockName, identifier as string);

const sename = "tsename";

// 获取信号量

const identifier = await rlock.acquireSemaphore(sename, 1);

// 刷新信号量

await rlock.refreshSemaphore(sename, identifier as string);

// 释放信号量

await rlock.releaseSemaphore(sename, identifier as string);

```
