How to add query function to redis in Node.js

An example

For a new module, we need to install the redis module in our project before it can be used.

Command

cnpm install redis

Create a new redis.js file with the following code:

//引入redis
var redis = require("redis");
//创建redis客户端
var client = redis.createClient("6379", "127.0.0.1");
//连接错误处理
client.on("error", function (error) {
  console.log(error);
});
//redis验证 （如果redis没有开启验证，此配置可以不写）
client.auth("123456");
//查找

client.select("15", function (error) {
  if (error) {
    console.log(error);
  } else {
    client.set("node_redis_key", JSON.stringify({ "name": "wolfy", age: 28 }), function (error, res) {
      if (error) {
        console.log(error);
      } else {
        console.log(res);
      };
      //操作完成，关闭redis连接
      client.end(true);

    });
  };
});
