如何使用Retrofit2和ArrayList進行解析？

Question

我嘗試解析數據，但是我的問題是我的json響應不是以[]開頭。 我使用這個網站（ http://www.jsonschema2pojo.org/ ）來幫助我，但是如果沒有[]，它將無法正常工作...

我的接口API.java

String BASE_URL = "https://statsapi.web.nhl.com/api/v1/people/";

@Headers("Content-Type: application/json")
@GET("8472382/stats?stats=statsSingleSeason&season=20172018")
Call<Players> getData();

這是我要解析的響應：

{
   "stats":[
      {
         "type":{
            "displayName":"statsSingleSeason"
         },
         "splits":[
            {
               "season":"20172018",
               "stat":{
                  "timeOnIce":"1711:02",
                  "assists":10,
                  "goals":3,
                  "pim":21,
                  "shots":93,
                  "games":81,
                  "hits":84,
                  "powerPlayGoals":0,
                  "powerPlayPoints":0,
                  "powerPlayTimeOnIce":"06:17",
                  "evenTimeOnIce":"1442:16",
                  "penaltyMinutes":"21",
                  "faceOffPct":0.0,
                  "shotPct":3.2,
                  "gameWinningGoals":0,
                  "overTimeGoals":0,
                  "shortHandedGoals":0,
                  "shortHandedPoints":0,
                  "shortHandedTimeOnIce":"262:29",
                  "blocked":188,
                  "plusMinus":-9,
                  "points":13,
                  "shifts":2292,
                  "timeOnIcePerGame":"21:07",
                  "evenTimeOnIcePerGame":"17:48",
                  "shortHandedTimeOnIcePerGame":"03:14",
                  "powerPlayTimeOnIcePerGame":"00:04"
               }
            }
         ]
      }
   ]
}

Answer 1

嘗試這個：

String BASE_URL = "https://statsapi.web.nhl.com/api/v1/people/";
    @Headers("Content-Type: application/json")
    @GET("8472382.json")
    Call<Stats> getData();

這些是在stackoverflow上發布的JSON的模型，但是您應該注意Json的URL，因為我嘗試了它，它顯示了另一個json結構。

在不同的Java文件中創建每個模型，然后添加public 。

class Stats {

    private List<Stat> stats;

    public List<Stat> getStats() {
        return stats;
    }

    public void setStats(List<Stat> stats) {
        this.stats = stats;
    }
}

public class Stat {

    private StatType type;
    private List<Split> splits;

    public StatType getType() {
        return type;
    }

    public void setType(StatType type) {
        this.type = type;
    }

    public List<Split> getSplits() {
        return splits;
    }

    public void setSplits(List<Split> splits) {
        this.splits = splits;
    }
}

class StatType {

    private String displayName;

    public String getDisplayName() {
        return displayName;
    }

    public void setDisplayName(String displayName) {
        this.displayName = displayName;
    }
}

class Split {
    private String season;
    StatDetail StatObject;


    // Getter Methods

    public String getSeason() {
        return season;
    }

    public StatDetail getStat() {
        return StatObject;
    }

    // Setter Methods

    public void setSeason(String season) {
        this.season = season;
    }

    public void setStat(StatDetail statObject) {
        this.StatObject = statObject;
    }
