鑑於以下JSON響應:獲取GsonConverterFactory來解析某些字段?
{
"status":true,
"doc":[
{
"_id":"9374",
"t_id":"5678",
"name":"Do calculus homework",
"description":"Finish all assigned homework from chapters 1 and 2",

}
我與Retrofit2一起用這個。我的服務類看起來是這樣的:
private HavocService(String baseUrl) {
//So network calls are async
RxJavaCallAdapterFactory rxAdapter = RxJavaCallAdapterFactory.createWithScheduler(Schedulers.io());
HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
OkHttpClient client = new OkHttpClient.Builder().addInterceptor(interceptor).build();
final Retrofit retrofit = new Retrofit.Builder()
.baseUrl(baseUrl)
.client(client)
.addCallAdapterFactory(rxAdapter)
.addConverterFactory(GsonConverterFactory.create())
.build();
mHavocApi = retrofit.create(HavocAPI.class);
}
,我實際處理中獲得的RX任務數據:
rxHelper.manageSubscription(HavocService.getInstance().getHavocAPI().getAllTasks(userId)
.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.compose(RxTiPresenterUtils.deliverLatestToView(this))
.subscribe(mListOfTasks -> {
this.mListOfTasks = mListOfTasks;
getView().setTaskList(mListOfTasks);
}, throwable -> {
LogUtil.e("Error with something.");
})
);
我如何告訴我GSONConverterFactory開始在"doc"
陣列解析?我並不在乎第一個"status"
字段。
我問,因爲我得到以下錯誤:java.lang.IllegalStateException: Expected BEGIN_ARRAY but was BEGIN_OBJECT at line 1 column 2 path $
。我很確定這是因爲GSON試圖解析第一個項目而不是"doc"
陣列。
我感謝任何和所有的幫助!
編輯
這裏是HavocAPI (我只關心getAllTasks()
現在的工作。)
public interface HavocAPI {
/**
* Creates a new Task
*
* @return status of whether or not the transaction was successful and the task that was created
*/
@Headers({"Accept: application/json", "Content-Type: application/json"})
@POST("task/create/")
Observable<List<Object>> createNewTask();
/**
* Deletes a specified Task using the taskId
*
* @param taskID of the task
* @return status of transaction
*/
@Headers({"Accept: application/json", "Content-Type: application/json"})
@POST("task/delete/{task_id}/")
Observable<Boolean> deleteTask(@Path("task_id") String taskID);
/**
* Updates a Task
*
* @return status of whether or not the transaction was successful and the task that was updated
*/
@Headers({"Accept: application/json", "Content-Type: application/json"})
@POST("task/update/")
Observable<List<Object>> updateTask();
/**
* Gets all Tasks by a specified User
*
* @param userId of the user
* @return list of all Tasks from the specified User
*/
@Headers({"Accept: application/json", "Content-Type: application/json"})
@GET("task/read/{user_id}/")
Observable<List<Task>> getAllTasks(@Path("user_id") String userId);
}
您需要向我們展示您的'HavocAPI'接口和您的getAllTasks api的返回類型模型。這個問題很可能與模型有關。 –
我的歉意。我不認爲這是必要的。我已經更新了OP。 – Nxt3
