我正在使用 Redis 并使用模块 Redis 从 nodejs 咨询它。
当我执行 client.multi() 并且 redis 服务器关闭时,回调不会发送错误并且 nodejs 应用程序终止。这是错误
/Users/a/db/node_modules/redis/index.js:151
throw callback_err;
^
TypeError: Cannot read property 'length' of undefined
at Command.callback (/Users/a/db/node_modules/redis/index.js:1098:35)

at Socket.EventEmitter.emit (events.js:95:17)

这是我的代码:构造函数类
var redis = require('redis');
var client;
function Redis(){
client = redis.createClient();
client.on("error", function (err) {
console.log("Error " + err);
});
}
Redis.prototype.multi = function(commands,callback){
var err = null;
client.multi(commands).exec(function (error, res) {
if(error){
process.nextTick(function(){
callback(error,null)
})
}else{
process.nextTick(function(){
callback(null,res)
})
}
});
}
