读取多个 JSON API 页面并解析数据

Question

Objective：从预报API中收集JSON数据，然后读取JSON precipIntensity 属性在指定的天数内，此代码从三开始。由于这需要许多步骤才能连贯地遵循，请尝试理解所有代码。

My main issue is trying to name the JSON code pages that return then put them into another context to read the precipIntensity property.

概述： 返回日期获取 UNIX 时间，然后为每个预测日请求一个 API。然后 API 被放入一个数组中。该数组放在一个 for() 循环中以请求每个 JSON 脚本...（现在该怎么办？我希望能够读取每个或计算一些东西，但我不知道如何请求格式化代码。我可以做剩下的部分）。 JSON 的样本可以在我的其他相关 post... （我发现API服务器帮我存储了数据...解决了）自 2015 年 5 月 1 日起编辑：

    //Get the back dated times and current in UNIX, 
   //later make a lookup that gives datediff from current date and user's date and adjust index i condition to equal exact days.
            var totalPrecipSinceDate;
            var threeDayAPITimes = [];

            for (var i = 0; i <= 2; i++) //place user userData-1 where i <= input
        {
            var myDate = new Date(); //
            var epoch = myDate.getTime(); //1318023197289 number of ms since epoch
            var unixEpoch = Math.round(epoch/1000)
            threeDayAPITimes[i] = Math.round(unixEpoch - (86400 * i));
                /*
                var epoch = (DateTime.UtcNow - new DateTime(1970, 1, 1)).TotalSeconds;
                threeDayAPITimes[i] = Math.round(epoch - (86400 * i));
                */
        }
        //Plan to convert UNIX dates to display

        //List of locations: LATITUDE,LONGITUDE
        var locations = ["46.3494,-85.5083"]

        var currentAPIKey ="privateAPIKey"; //gets an APIkey from user from forecaster input.

 var listAPIs = "";

$.each(threeDayAPITimes, function(i, time) {
    var darkForecastAPI= "https://api.forecast.io/forecast/" + currentAPIKey + "/" + locations + "," + time;
    $.getJSON(darkForecastAPI, {
        tags: "WxAPI[" + i + "]",  //Is this tag the name of each JSON page? I tried to index it incase this is how to refer to the JSON formatted code from the APIs.
        tagmode: "any",
        format: "json"
    }, function(result) {
        // Process the result object
    });
    });
  //Process result in foreach loop   
         var eachPrecipSum = 0;
    if(result.currently.precipIntensity >=0 && result.currently.precipType == "rain")
        {
            $.each(result, function() {
              eachPrecipSum += (this.currently.precipIntensity);
              totalPrecipSinceDate += eachPrecipSum ;
        });

        }       
            alert(eachPrecipSum );

Answer 1

你的循环应该是这样的：

$.each(threeDayAPITimes, function(i, time) {
    var darkForecastAPI= "https://api.forecast.io/forecast/" + currentAPIKey + "/" + locations + "," + time;
    $.getJSON(darkForecastAPI, {
        tags: "WxAPI[" + i + "]",  //Is this tag the name of each JSON page? I tried to index it incase this is how to refer to the JSON formatted code from the APIs.
        tagmode: "any",
        format: "json"
    }, function(result) {
        // Process the result object
    });
}
