NodeJS HTTP请求未按顺序执行

如何解决《NodeJSHTTP请求未按顺序执行》经验,为你挑选了0个好方法。

第一篇文章,但感谢所有人的所有信息!

关于这个问题.我有一些代码,我试图迭代JSON文件并对数组中的每个对象执行HTTP Get Request.问题似乎出现在我执行http get请求时,它不是按顺序执行,也不是完成.它在我的API大约6-9次调用后挂起.

示例JSON:

    [
  {
    "Name": "ActClgStpt",
    "Address": 326,
    "Slot": 1
  },
  {
    "Name": "ActHtgStpt",
    "Address": 324,
    "Slot": 1
  },
  {
    "Name": "AdvanceCool",
    "Address": 21,
    "Slot": 1
  }
]

迭代JSON:

    sedona.jsonInputAddress('Unit1GWRenton', logMe);

function logMe() {
    for(var i in config)
    {

        var name = config[i].Name;
        var address = config[i].Address;
        var slot = config[i].Slot;
        console.log(name + " " + address + " " + slot);
        sedona.collectValues("192.168.101.14", 2001, config[i].Name, config[i].Address, config[i].Slot,function(){console.log("Done")})
    }


}

我在API调用的每个循环上执行的函数的副本.我有一个回调设置,但我认为我可能没有正确设置它:

collectValues:function(site,port,name,address,slot,callback){

    /* Build Scrape Constructor */
    var url = 'http://' + (site) + ':' + (port) + '/twave/app/' + (address);

    /* Slice out Unit # */
    unitNumber = port.toString().slice(2, 4);

    /* Create slotid */
    var slotmaker = "slot" + (slot);

    /* Get ISO Timestamp */
    var dt = new Date();
    var isoDate = dt.toISOString();
    isoTime = isoDate.slice(0,19).replace('T', ' ').concat('.000000+00:00');

    /* Make API Call */
    request.get({
        agent: false,
        url: url,
        json: true
    }, function response (error, response, body) {
        if (!error && response.statusCode === 200) {

            // Grab Point Name
            pointname = name;

            // Grab Point Value
            var value = body.slots;
            var slot = value[slotmaker];
            slotvalue = slot.value;

            // Testing Logs
            console.log(isoTime + " " +pointname + " " + slotvalue);

            callback()



        }
    });



}

你认为我可以在代码中改进的任何东西都会很棒.在Node上每天都在学习!
