无法从API访问特定的JSON数据 [英] Cannot access specific JSON data from API

问题描述

我正在尝试从API中获取数据- https://sportsbook.draftkings.com/api/odds/v1/leagues/3/offers/gamelines.json .和 https://www.fantasylabs.com/api/sportevents/3/2019_06_17

I am trying to fetch data from API - https://sportsbook.draftkings.com/api/odds/v1/leagues/3/offers/gamelines.json. and https://www.fantasylabs.com/api/sportevents/3/2019_06_17

我已经使用forkJoin连接了2个API

I have jointed 2 API using forkJoin

从API- https://sportsbook. draftkings.com/api/odds/v1/leagues/3/offers/gamelines.json 我成功访问了行列.但是，在检索数据时，它会提取名称为line的所有数据.我只想访问每个游戏的第一行.例如，对于第一个游戏的"line": "+3.5000".然后"line": "+46.0000"第二局，依此类推

From API- https://sportsbook.draftkings.com/api/odds/v1/leagues/3/offers/gamelines.json I am successful in accessing line column. But while retrieving data it fetches all data where name is line. I just want to access 1st occurence of line for each game. For eg "line": "+3.5000" for 1st game. Then "line": "+46.0000" for second game and so on

我还发现很难访问两支球队的赔率美国数据.例如，对于第一游戏的数据，我感兴趣的是第一游戏的"oddsAmerican": "+148"和"oddsAmerican": "-182"

I am also finding it difficult to access oddsAmerican data for both the teams. For eg in 1st game data I am interested in fetching are "oddsAmerican": "+148" and "oddsAmerican": "-182" for 1st game

这是我的代码

推荐答案

要获取line和oddsAmerican的首次出现，可以执行以下操作:

To get the first occurrence of line and oddsAmerican, you can do like this:

ngOnInit() {

    const character = this.http.get('https://sportsbook.draftkings.com/api/odds/v1/leagues/3/offers/gamelines.json').pipe(map((re: any) => re.events));
    const characterHomeworld = this.http.get('https://www.fantasylabs.com/api/sportevents/3/2019_06_17');

    this.firstLinePerGame = new Array<string>();
    this.oddsAmericans = new Array<string>();

    forkJoin([character, characterHomeworld]).subscribe(([draftkingsResp, fantasylabsResp]) => {      

      this.allhomeTeamName = draftkingsResp.map(r => r.homeTeamName);
      this.allawayTeamName = draftkingsResp.map(r => r.awayTeamName);
      this.allline = draftkingsResp.map(r=>r.offers).flat().map(r => r.outcomes).flat().map(o => o.line);
      this.allline = this.allline.filter(l => !!l);
      this.createAllArray();      

      draftkingsResp.forEach(r => {

        if(r.offers && r.offers.length) {

          if(r.offers.length === 3) {
            const firstGame = r.offers[0].outcomes[0];
            this.firstLinePerGame.push(firstGame.line);

            const secondGame = r.offers[2].outcomes[0];
            this.firstLinePerGame.push(secondGame.line);

            this.oddsAmericans.push(r.offers[1].outcomes[0].oddsAmerican)
            this.oddsAmericans.push(r.offers[1].outcomes[1].oddsAmerican)

          } else if(r.offers.length === 1) {

            const firstGame = r.offers[0].outcomes[0];
            this.firstLinePerGame.push(firstGame.line);

          } else if(r.offers.length === 2) {
            console.log('******************')
          }
        }
      })      

      console.log(this.firstLinePerGame.filter(l => l));
      console.log(this.oddsAmericans);
    });
  }
