go mod init github.com/k6io/xk6-redis
需要push github
package redis

go get -u github.com/k6io/xk6/cmd/xk6
xk6 build v0.29.0 --with github.com/k6io/xk6-redis
说明：我们构建的时候也可以指定本地代码位置（类似nginx 模块的构建）
xk6 build v0.29.0 \
--with github.com/k6io/xk6-redis="/absolute/path/to/xk6-redis"
import redis from ‘k6/x/redis‘;
?
const client = new redis.Client({
addr: ‘localhost:6379‘,
password: ‘‘,
db: 0,
});
?
export default function () {
client.set(‘mykey‘, ‘myvalue‘, 0);
console.log(`mykey => ${client.get(‘mykey‘)}`);
}
