没有从改造 api 调用中得到正确的响应

Question

我正在使用改造 API 来获取数据，为此，我根据需要创建了 POJO classes。

这是我的 POJO classes，1. 报告

@SerializedName("success")
@Expose
private Boolean success;
@SerializedName("data")
@Expose
private List<Datum> data = null;

public Boolean getSuccess() {
    return success;
}

public void setSuccess(Boolean success) {
    this.success = success;
}

public List<Datum> getData() {
    return data;
}

public void setData(List<Datum> data) {
    this.data = data;
}

基准

 @SerializedName("_id")
 @Expose
 private String id;
 @SerializedName("seq")
 @Expose
 private Integer seq;
 @SerializedName("imei")
 @Expose

 public Integer getV() {
     return v;

 public void setV(Integer v) {
     this.v = v;
 }

以下是我尝试使用 Report class.

以 Datum list 形式获取数据的方法

这是 activity 代码...

Call<Report> call = RetrofitClient
                    .getInstance()
                    .getApi()
                    .getAlltheReports(reportModel);


            call.enqueue(new Callback<Report>() {
                @Override
                public void onResponse(Call<Report> call, Response<Report> response) {

                    Log.d("responseBodyyyyyyyyy", String.valueOf(response.body()));

                    Report example = response.body();

                    if (example != null) {
                        Log.d("gettingNull", "DATA");

                        List<Datum> data = response.body().getData();
                        Log.d("dataaaaaaaaaaaaaaaa", String.valueOf(data));


                    } else {
                        Log.d("gettingNull", "Null");
                    }
                }

                @Override
                public void onFailure(Call<Report> call, Throwable t) {
                    Log.d("error", String.valueOf(t));
                }
            });

其中，改装调用reportModel只不过是JSON数据。

供参考，

ReportModel:

ReportModelJson reportModel = new ReportModelJson("353081090133664", "Asia/Kolkata", "02-06-2022", "02-10-2022");

我正在这样发布 API 电话：-

@POST("getonlyselect")
Call<Report> getAlltheReports(
        @Body ReportModelJson ReportModelJson
);

这是我试图获取数据，但我没有得到正确的响应，而是得到 packagename@xxxx。

供参考：

com.example.abcd.Screens.Models.Datum@42df5e8

我得到的回复是这样的：-

{
"success": true,
"data": [
    {
        "_id": "61fed1d527824e063e318124",
        "seq": 21,
        "imei": "353081090133664",
        "lat": "22.472927",
        "lon": "70.080795",
        "etype": "stop",
        "nos": "5",
        "rssi": "-51",
        "hac": "1.5",
        "spd": "2",
        "btv": "12.34",
        "address": "abcd",
        "dt": "1644089809000",
        "erpm": "N",
        "thpos": "N",
        "erntm": "N",
        "fgrl": "N",
        "dtml": "N",
        "flvl": "N",
        "ftype": "N",
        "eot": "N",
        "ect": "N",
        "odm": "N",
        "date": "2022-02-05T19:36:53.087Z",
        "__v": 0
    }
]

}

请帮我找出解决办法。

Answer 1

据我了解你的代码，改造 API 调用中没有任何错误，你从 API 获得的打印值有错误。

正如我在您的代码中看到的，您已使用以下代码打印从 API 获得的数据。

List<Datum> data = response.body().getData();
 Log.d("dataaaaaaaaaaaaaaaa", String.valueOf(data));

此外，Data 是您尝试使用 Log.d 打印的数组。所以如果你想打印你的数据，你可以设置 for 循环来打印每个对象数据，如下所示。

List<Datum> data = response.body().getData();
for(int l=0; l<data.size(); l++)
{
  Log.d("dataaaaaaaaaaaaaaaa", data.get(l)._id())
 }

希望这能帮助您解决问题。
