Question

使用Meteor-react框架为汽车租赁停车场创建了一个应用程序（iOS）。我想跟踪使用GPS移动的司机。这样我就能发现他的结账状态。我需要在办理登机手续后计算停车位和司机位置之间的距离，以便我可以向驾驶员发送推送消息，看他是否即将结账。在进行基于GPS的结账的实际开发之前，需要一个建议是否真的可行？什么是利弊？

现在我正在通过npm包＆＃34; gps-tracking＆＃34;这是一个GPS听众。

我在/server/gps.js

中添加了代码

var gps = require("gps-tracking");
var options = {
'debug'                 : true, //We don't want to debug info 
 automatically. We are going to log everything manually so you can 
 check what happens everywhere
'port'                  : 8000,
'device_adapter'        : "TK103"
}

var server = gps.server(options,function(device,connection){
console.log(options);
console.log(device);
console.log(connection);
device.on("connected",function(data){
    console.log("I'm a new device connected");
    return data;

});
device.on("login_request",function(device_id,msg_parts){

    console.log('Hey! I want to start transmiting my position. Please accept me. My name is '+device_id);

    this.login_authorized(true); 

    console.log("Ok, "+device_id+", you're accepted!");

});
device.on("ping",function(data){
    //this = device
    console.log("I'm here: "+data.latitude+", "+data.longitude+" ("+this.getUID()+")");

    //Look what informations the device sends to you (maybe velocity, gas level, etc)
    //console.log(data);
    return data;

});
device.on("alarm",function(alarm_code,alarm_data,msg_data){
    console.log("Help! Something happend: "+alarm_code+" 
("+alarm_data.msg+")");
}); 
//Also, you can listen on the native connection object
connection.on('data',function(data){
    //echo raw data package
    //console.log(data.toString()); 
})
});

提前致谢！
