我的Android Java REST API代码与另一个使用JSON对象层次结构(又名List-bracket-object1-bracket object2)的REST API完美配合。现在我转到了一个简化的API(googlemaps时区 - 只有一个带有5个字段的简单对象),但我无法弄清楚如何将google数据放入我的对象中。
我收到状态码200,我可以在我的logcat中看到googlemaps输出/ JSON,但我的对象为null。我读了这篇文章" 0 Retrofit 2:response.body()为null,但状态代码为200 2"我相信我有同样的问题,但我不知道如何调整我的对象模型来修复它。这是我的东西......
1 - 我正在点击的API / URL: https://maps.googleapis.com/maps/api/timezone/json?location=39.6034810,-119.6822510×tamp=1331161200&key=xxxxxx
2 - API / URL返回的内容(来自我的LogCat)
D/OkHttp: {
D/OkHttp: "dstOffset" : 0,
D/OkHttp: "rawOffset" : -28800,
D/OkHttp: "status" : "OK",
D/OkHttp: "timeZoneId" : "America/Los_Angeles",
D/OkHttp: "timeZoneName" : "Pacific Standard Time"
D/OkHttp: }
3 - Logcat显示对象为空
Log.e(" main ", " apt " + response.body().getResults());
E/ main: apt null
4 - 调用例程
ApiInterface apiService = ApiClient.getClient(1).create(ApiInterface.class);
Call<ApiTimes> call = apiService.getTime(location,epoch,GOOG_TZ_KEY);
call.enqueue(new Callback<ApiTimes>() {
@Override
public void onResponse(Call<ApiTimes> call, Response<ApiTimes> response) {
int statusCode = response.code();
Log.e(" main ", " apt " + response.body().getResults());
}
@Override
public void onFailure(Call<ApiTimes> call, Throwable t) {
Log.e(" getFS ", t.toString());
}
});
5 - 对象。
public class ApiTime {
@SerializedName("apitime")
private ApiTime apitime;
@SerializedName("dstOffset")
@Expose
private Long dstOffset;
@SerializedName("rawOffset")
@Expose
private Long rawOffset;
@SerializedName("status")
@Expose
private String status;
@SerializedName("timeZoneId")
@Expose
private String timeZoneId;
@SerializedName("timeZoneName")
@Expose
private String timeZoneName;
public ApiTime(Long dstOffset, Long rawOffset, String status, String timeZoneId, String timeZoneName) {
this.dstOffset = dstOffset ;
this.rawOffset = rawOffset ;
this.status = status ;
this.timeZoneId = timeZoneId ;
this.timeZoneName = timeZoneName ;
}
public ApiTime getResults() {
return apitime;
}
public void setResults(ApiTime apitimes) {
this.apitime = apitime;
}
public Long getDstOffset() {
return dstOffset;
}
public void setDstOffset(Long dstOffset) {
this.dstOffset = dstOffset;
}
public Long getRawOffset() {
return rawOffset;
}
public void setRawOffset(Long rawOffset) {
this.rawOffset = rawOffset;
}
public String getStatus() {
return status;
}
public void setStatus(String status) {
this.status = status;
}
public String getTimeZoneId() {
return timeZoneId;
}
public void setTimeZoneId(String timeZoneId) {
this.timeZoneId = timeZoneId;
}
public String getTimeZoneName() {
return timeZoneName;
}
public void setTimeZoneName(String timeZoneName) {
this.timeZoneName = timeZoneName;
}
@Override
public String toString() {
return "ApiTime{" +
"dstOffset=" + dstOffset +
", rawOffset=" + rawOffset +
", status='" + status + '\'' +
", timeZoneId='" + timeZoneId + '\'' +
", timeZoneName='" + timeZoneName + '\'' +
'}';
}
}
6 - 以下是两个调用例程:
public class ApiClient {
public static final String URL0 = blah blah
public static final String URL1 = "https://maps.googleapis.com/maps/api/timezone/";
private static Retrofit retrofit = null;
public static String BASE_URL = "www.google.com";
public static Retrofit getClient(int url) {
BASE_URL = URL0;
if (url == 1){
BASE_URL = URL1;
}
//The following block of code generates OkHttpClient loggging to LogCat.
//Only use if debugging.
OkHttpClient.Builder client = new OkHttpClient.Builder();
HttpLoggingInterceptor loggingInterceptor = new HttpLoggingInterceptor();
loggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
client.addInterceptor(loggingInterceptor);
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(BASE_URL)
.client(client.build())
.addConverterFactory(GsonConverterFactory.create())
.build();
//Retrofit retrofit = new Retrofit.Builder()
// .baseUrl(BASE_URL)
// .addConverterFactory(GsonConverterFactory.create())
// .build();
return retrofit;
}
}
public interface ApiInterface {
@GET("json")
Call<ApiTimes> getTime(@Query("location") String location, @Query("timestamp") String timestamp, @Query("key") String key);
}
答案 0 :(得分:1)
您似乎应该使用ApiTime
代替ApiTimes
我在日志中的json中看不到@SerializedName("apitimes")
public interface ApiInterface {
@GET("json")
Call<ApiTime> getTime(@Query("location") String location, @Query("timestamp") String timestamp, @Query("key") String key);
}
-
ApiInterface apiService = ApiClient.getClient(1).create(ApiInterface.class);
Call<ApiTime> call = apiService.getTime(location, epoch, GOOG_TZ_KEY);
call.enqueue(new Callback<ApiTime>() {
@Override
public void onResponse(Call<ApiTime> call, Response<ApiTime> response) {
int statusCode = response.code();
Log.e("main", "apt " + response.body());
}
@Override
public void onFailure(Call<ApiTime> call, Throwable t) {
Log.e("getFS ", t.toString());
}
});
-
public class ApiTime {
@SerializedName("dstOffset")
private Long dstOffset;
@SerializedName("rawOffset")
private Long rawOffset;
@SerializedName("status")
private String status;
@SerializedName("timeZoneId")
private String timeZoneId;
@SerializedName("timeZoneName")
private String timeZoneName;
// getters here
}
