Для L oop продолжает выполнение, четная длина указана в node js

Question

Я использую API Tibco, чтобы получить какой-либо статус сервиса (запущен или остановлен). Мне нужны определенные значения из полученных json. Я использовал для l oop, но это продолжает цикл больше, чем его длина. Может кто-нибудь, пожалуйста, посоветуйте.

Ниже приведен код

var async = require('async');
var fetch = require('node-fetch');
const HttpsProxyAgent = require('https-proxy-agent');

var API_PORT = "8079";
var ALL_DOMAIN_API = "/bw/v1/browse/domains?full=false&status=true";
var URLS = {
    cit1: "http://x.x.x.x",
    cit2: "http://y.y.y.y"
};

exports.getdomainstatus = function (req, res) {
    if (!req.body.env || !URLS[req.body.env]) {
        res.status(500).json({ error: "Enviroment details not found...!" });
        return;
    }

    var url = URLS[req.body.env] + ":" + API_PORT + ALL_DOMAIN_API;
    //console.log(req.body.env);
    //console.log("+++++++++++++++++++++++++++++++++++++++")
    console.log(url);
    fetch(url, {
        method: 'GET',
        agent: new HttpsProxyAgent('http://a.a.0.0:50683')
    }).then(resRaw => {
        return resRaw.text();
    }).then(resJson => {
        if (!resJson || !resJson.length) {
            res.status(200).json({ domainstatus: [] });
            return;
        }

        resJson = JSON.parse(resJson);
        //console.log(resJson);

        var domainstatus = [];
        async.eachLimit(resJson, 1, (domain, callback) => {
            if (!domain || !domain.name) {
                callback();
                return;
            }

            var statusurl = URLS[req.body.env] + ":" + API_PORT + "/bw/v1/browse/apps?domain=" + domain.name + "&full=false&status=true";
            //console.log(statusurl);
            fetch(statusurl, {
                method: 'GET',
                agent: new HttpsProxyAgent('http://0.0.0.0:0000')
            }).then(resRaw => {
                return resRaw.text();
            }).then(itemJson => {
                if (!itemJson || !itemJson.length) {
                    callback();
                    return;
                }

                itemJson = JSON.parse(itemJson);

                if (!itemJson || !itemJson[0]) {
                    callback();
                    return;
                }
                // console.log("/////////////////////////////////////")
                // //console.log(itemJson)

                // console.log("===================")
                console.log(itemJson.length)
                //Here I get Output as 9

                console.log("+++++++++++++++++++++++++++++++++")

                for (let i = 0; i < itemJson.length; i++) {
                    //itemJson = itemJson[0];
                    console.log(itemJson[i].name)
                    //Here I get correct output
                    var temp = {
                        owner: itemJson[i].owner,
                        name: itemJson[i].name,
                        date: itemJson[i].date,
                        description: itemJson[i].description,
                        status: itemJson[i].state,
                        domainName: itemJson[i].domainName,
                    }
                    console.log("--------")
                    console.log(i)
                    console.log(temp)
                    //domainstatus.push(temp);
                    //temp.status(200).json({ domainstatus: domainstatus });


                }

                callback();
            }).catch(err => {
                callback();
            });
        }, () => {
            console.log("All Completed...!")

        });
    }).catch(err => {
        res.status(500).json({ error: err });
    });
} 

Я тоже пробовал foreach, но тщетно. Это как-то связано с asyn c .eachLimit. Я попытался использовать второй параметр eachLimit как 1 вместо 10, но тот же результат. пожалуйста, найдите следующий вывод. после 0 до 9 (элемент Json .lenth) он снова начинается с 0 до 9 и повторяется снова.

Answer 1

У вас есть двойной l oop, asyn c .eachLimit уже зацикливается на вашем json, и каждая такая итерация, также имеет для него, это двойной l oop, удалите либо внутри и оставайтесь с asyn c .eachLimit или оставайтесь с for без использования asyn c .eachLimit. (лучше, конечно, использовать asyn c, а затем циклически переключаться с)
