请教一下各位大大怎样获取到用户的输入。 具体的需求是：我目前使用adbkit来获取连接到服务器的手机，需要在同一个线程中开启一个服务并监听用户的输入，如果用户输入‘get’，我就返回目前已有的手机信息给它，不知道应该怎样实现？ 现在的代码如下：
#!/usr/bin/env node var adb = require(‘adbkit’); var client = adb.createClient(); var cellphones = require("./CellPhones"); var JsonCellList = {“cellphone” : []};
client.trackDevices() .then(function(tracker) { tracker.on(‘add’, function(device) { console.log(‘Device %s was plugged in’, device.id); var time = new Date().getTime(); var item = { “id” : device.id, “type” : device.type, “timestamp” : time, “status” : 0 }; JsonCellList.cellphone.push(item); cellphones.setCells(JsonCellList); console.log(cellphones.getCells()); }); tracker.on(‘remove’, function(device) { console.log(‘Device %s was unplugged’, device.id); delId = device.id; for(i in JsonCellList.cellphone) { if(JsonCellList.cellphone[i].id == delId) JsonCellList.cellphone.splice(i,1); } cellphones.setCells(JsonCellList); console.log(cellphones.getCells()); }); tracker.on(‘end’, function() { console.log(‘Tracking stopped’); }); }) .catch(function(err) { console.error(‘Something went wrong:’, err.stack); });
