Question

我向API发出了一些请求。它来自游戏。首先我要求获得一个身份证，然后使用该身份证我得到一个现场比赛，而我所取出的是每个人正在玩的角色以及玩家的名字。我在Python中做了这个作为我的第一个脚本，但说实话，我对NodeJS中的方法感到困惑。

问题的根源在于我正在做一个嵌套循环。它打印整个数据加上每个人都玩10次的冠军。

这是请求代码的一部分：

// SUMMONER ID TO FETCH DATA
request.get(`https://lan.api.pvp.net/api/lol/lan/v1.4/summoner/by-name/ronalxo?api_key=${riotKey}`, (err, resp, body) => {
    let parseBody = JSON.parse(body);

    let summonerID = parseBody.ronalxo.id;

    // LIVE GAME
    request.get(`https://lan.api.pvp.net/observer-mode/rest/consumer/getSpectatorGameInfo/LA1/${summonerID}?api_key=${riotKey}`, (err, resp, body) => {
        let parseBodyGameInfo = JSON.parse(body);
        let idsSeen = [];
        let championBeingPlayed = [];

        for (let t in parseBodyGameInfo.participants) {
            championBeingPlayed.push(parseBodyGameInfo.participants[t].championId);
        }

        //console.log(championBeingPlayed);

        // CHAMPION TO COMPARE ID WITH KEY AND SEE IF IT MATCHES THEN DISPLAY THE CHAMPION NAME
        // THIS IS A NESTED REQUEST
        request.get(`https://global.api.pvp.net/api/lol/static-data/lan/v1.2/champion?api_key=${riotKey}`, (err, resp, body) => {
        let parsechampionIds = JSON.parse(body);

            for (let x in parsechampionIds.data) {
                if (parsechampionIds.data.hasOwnProperty(x)) { // LOOKS FOR ID OF CHARACTER
                    let championId = parsechampionIds.data[x].id;

                    if (championBeingPlayed.indexOf(championId) !== -1 ) { // THE ID FROM ABOVE GETS MATCHED WITH OTHER IDS HERE TO DISPLAY OTHER DATA
                        for (var i in parseBodyGameInfo.participants) { // CHECKS FOR PARTICIPANTS ON MATCH
                            if (parseBodyGameInfo.participants[i].teamId === 100) { // CHECKS THE ID OF THE TEAM THAT THE PLAYER BELONGS TO
                                if (idsSeen.indexOf(parseBodyGameInfo.participants[i].teamId) === -1 ) { // CHECKS IF TEAM ID IS IN ARRAY
                                    console.log(`***** BLUE TEAM *****`); // I PUT THIS HERE SO IT DISPLAYS ONLY ONCE, NOT 10 TIMES
                                }

                                console.log(`${parseBodyGameInfo.participants[i].summonerName} playing ${parsechampionIds.data[x].name}`);
                            }
                            idsSeen.push(parseBodyGameInfo.participants[i].teamId); 
                        }
                    }
                }
            }

        });
    });
});

输出是这样的：

Anrez playing Thresh
I AM MIZUKAGE  playing Thresh
EriickX playing Thresh
xDBanned playing Thresh
yayobuenavibra playing Thresh
Anrez playing Cho'Gath
I AM MIZUKAGE  playing Cho'Gath
EriickX playing Cho'Gath
xDBanned playing Cho'Gath
yayobuenavibra playing Cho'Gath
Anrez playing Xin Zhao
I AM MIZUKAGE  playing Xin Zhao
EriickX playing Xin Zhao
xDBanned playing Xin Zhao
yayobuenavibra playing Xin Zhao

正如你所看到的，它打印同一个冠军5次，因为有10个，它被打印10次。显然，这不是我希望它拥有的行为。我希望输出如下：

Anrez playing 
I AM MIZUKAGE  playing Xin zhao
EriickX playing Thresh
xDBanned playing Cho gath
yayobuenavibra playing Tristana
Anrez playing Miss Fortune

哪个是字符的名称，所以，我想知道将 for loop 放在哪里（除了我应该做的好的重构）。

似乎缺少检查以匹配 championId 的外部 for 循环的 championId 。尝试添加以下if语句：

let tlsum =
    match sum tl with
    | None -> (* figure this part out *)
    | Some n -> (* figure this part out *)

您可以在this plunker中看到演示 - 控制台语句在浏览器控制台中可见。

来自循环的数据正在显示我需要的次数
