[大数据]nodejs redis client api

?由于mac redis client无法进行快速批量删除，故想通过脚本来执行批量删除。

?一、安装依赖

npm install ioredis mocha

二、脚本

test.js

const Redis = require('ioredis');

const redis = new Redis({
	port: 6379, // Redis port
	host: 'xxxx.redis.rds.aliyuncs.com', // Redis host
	family: 6, // 4 (IPv4) or 6 (IPv6)
	password: 'xxxx',
	db: 0
});

describe('', async () => {
	it.skip('设置key', async () => {
		try {
			await redis.set('foo', 'bar'); // returns promise which resolves to string, "OK"
		} catch (error) {
			await console.error(error);
		}
	});

	it.skip('查询指定key', async () => {
		try {
			var result = await redis.get('USER_REMAINING_-1103');
			await console.log(`GET USER_REMAINING_-1103:${result}`); // Promise resolves to "bar"
		} catch (error) {
			await console.error(error);
		}
	});
	it('删除 USER_REMAINING_', async () => {
		try {
			for (let index = 1209; index < 1309; index++) {
				var result = await redis.del(`USER_REMAINING_-${index}`);
				await console.log(`DEL USER_REMAINING_-${index}:${result}:${result}`); // Promise resolves to "bar"
			}
		} catch (error) {
			await console.error(error);
		}
	});

	it('删除 GIFT_TOTAL_NUM_', async () => {
		try {
			for (let index = 1; index < 6; index++) {
				var result = await redis.del(`GIFT_TOTAL_NUM_${index}`);
				await console.log(`DEL GIFT_TOTAL_NUM_${index}:${result}`); // Promise resolves to "bar"
			}
		} catch (error) {
			await console.error(error);
		}
	});

	it('删除 GIFT_SEND_DAY_NUM_', async () => {
		try {
			for (let index = 1; index < 6; index++) {
				var result = await redis.del(`GIFT_SEND_DAY_NUM_${index}`);
				await console.log(`DEL GIFT_SEND_DAY_NUM_${index}:${result}`); // Promise resolves to "bar"
			}
		} catch (error) {
			await console.error(error);
		}
	});
});

?三、执行结果
