Question

我正在尝试从android应用程序中的api获取数据。我正在使用Kotlin，Retrofit2，rxjava，viewmodel和dagger。这不会在api上进行任何调用，也不会引发任何错误。

这是我的JSON，将在成功调用后收到。

{"data":[{"uid":"bf167b90-e8a0-41b6-aac2-71d305a3f41a",
         "title":"category 1",
         "image":""}],
 "status":{"code":105,"msg":"categories data"}}

这是我的数据类

@Entity(tableName="categories")
data class Category(@PrimaryKey(autoGenerate = true) var id: Long?,
            @ColumnInfo(name = "remote_id") var remoteID: String,
            @ColumnInfo(name = "title") var title:String,
            @ColumnInfo(name = "parent") var parent: String,
            @ColumnInfo(name = "status") var status: String,
            @ColumnInfo(name = "created_at") var createdAt: String,
            @ColumnInfo(name = "created_by") var createdBy: String) {
constructor():this(null,"","","","","",
        "")
}

data class CategoryResult(val status: Status, val data: 
List<CategoryJSON>)

data class Status(val code:String, val msg:String)

data class CategoryJSON(val uid: String, val title: String, val 
image:String)

这是我的服务接口代码。

interface PMAPI {
   @GET("category")
   fun getCategories(): Observable<CategoryResult>

   @GET("category")
   fun getTasks(): Observable<List<Task>>
}

@Provides
@Singleton
fun provideHttpCache(application: Application): Cache {
    val cacheSize = 10 * 1024 * 1024
    return Cache(application.cacheDir, cacheSize.toLong())
}

@Provides
@Singleton
fun provideGson(): Gson {
    val gsonBuilder = GsonBuilder()
    gsonBuilder.setFieldNamingPolicy(FieldNamingPolicy.LOWER_CASE_WITH_UNDERSCORES)
    return gsonBuilder.create()
}

@Provides
@Singleton
fun provideOkhttpClient(cache: Cache): OkHttpClient {
    val interceptor = HttpLoggingInterceptor()
    interceptor.setLevel(HttpLoggingInterceptor.Level.BODY)
    val client = OkHttpClient.Builder()
    client.cache(cache)
    client.addInterceptor(interceptor)
    return client.build()
}

@Provides
@Singleton
fun provideRetrofit(gson: Gson, okHttpClient: OkHttpClient): Retrofit {
    return Retrofit.Builder()
            .addConverterFactory(GsonConverterFactory.create(gson))
            .addCallAdapterFactory(RxJava2CallAdapterFactory.create())
            .baseUrl(mBaseUrl)
            .client(okHttpClient)
            .build()
}

@Provides
@Singleton
fun providePMAPI(retrofit: Retrofit): PMAPI {
    return retrofit.create(PMAPI::class.java)
}

存储库

     fun getCategoriesFromApi(): Observable<List<Category>> {
    Log.d("Category Repository", "Getting Categories from Api")

    var categoryResult = api.getCategories()
    var categories = mutableListOf<Category>()

    categoryResult.doOnNext {

               Log.d("Category Repository","Dispatching categories from API...")


              it.data.forEach {
                  var category = Category()
                  category.remoteID = it.uid
                  category.title = it.title
                  categories.add(category)
              }
              storeProjectsInDb(categories)

           }
    return Observable.fromArray(categories)

}

android应用未调用api
