How Node.js operates redis to add query function

An example

The installation of the redis server will not be introduced here, the focus is not here. Those who are interested can install it themselves.

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);

    });
  };
});
