改装2不执行请求

我的应用程序需要连接到 使用 . 所以我创建了下一个API模型:

interface IGitHubApi {
    @GET("login/oauth/access_token")
    fun getAccessToken(
        @Query("client_id") clientId: String = GitHub.CLIENT_ID,
        @Query("client_secret") clientSecret: String = GitHub.CLIENT_SECRET,
        @Query("code") code: String
    ): Single<String>
}

我知道我可以提供一个类来描述JSON结构和 格森

在我为 改装2 :

@Component(modules = [GitHubApiModule::class])
interface IGitHubApiComponent {
    fun getGitHubService(): IGitHubApi
}

@Module
class GitHubApiModule {

    @Provides
    fun provideGitHubApi(retrofit: Retrofit): IGitHubApi {
        return retrofit.create(IGitHubApi::class.java)
    }

    @Provides
    fun provideRetrofit(gsonConverterFactory: GsonConverterFactory,
                        rxJava2CallAdapterFactory: RxJava2CallAdapterFactory): Retrofit {
        return Retrofit.Builder()
            .baseUrl(GitHub.BASE_URL)
            .addConverterFactory(gsonConverterFactory)
            .addCallAdapterFactory(rxJava2CallAdapterFactory)
            .build()
    }

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

    @Provides
    fun provideGsonConverterFactory(gson: Gson): GsonConverterFactory {
        return GsonConverterFactory.create(gson)
    }

    @Provides
    fun provideRxJava2CallAdapterFactory(): RxJava2CallAdapterFactory {
        return RxJava2CallAdapterFactory.create()
    }
}

并连接 匕首2

class AccountViewModel(app: Application) : AndroidViewModel(app) {

    var label: ObservableField<String> = ObservableField()
    var isLoading: ObservableBoolean = ObservableBoolean(true)
    var progress: ObservableInt = ObservableInt(0)
    private var gitHubApi: IGitHubApi = DaggerIGitHubApiComponent.create().getGitHubService()

    private fun getErrorMsg(app: Application, hasAccount: Boolean): String {
        return if (hasAccount) {
            app.getString(R.string.err_account_update_failed)
        } else {
            app.getString(R.string.err_account_creation_failed)
        }
    }

    fun createOrUpdateAccount(authorizationCode: String?) {
        val app = getApplication<App>()
        val accountType = app.getString(R.string.account_type_git)
        val accountManager = AccountManager.get(app.applicationContext)
        val accounts = accountManager.getAccountsByType(accountType)

        label.set(app.getString(R.string.msg_account_creating))

        if (authorizationCode == null) {
            val msg = getErrorMsg(app, accounts.isNotEmpty())
            label.set(msg)

            return //Break operation
        }

        gitHubApi.getAccessToken(code = authorizationCode)
            .subscribeOn(Schedulers.io())
            .observeOn(AndroidSchedulers.mainThread())
            .subscribeBy(
                onSuccess = {
                    label.set(it)
                    progress.set(100)
                    isLoading.set(false)
                },
                onError = {
                    Log.e("AccountViewModel", it.message?: "Could not retrieve an access token.", it)
                    val msg = getErrorMsg(app, accounts.isNotEmpty())
                    label.set(msg)
                }
            )
            .dispose()
    }
}

Creating an account... 这意味着 onSuccess 和 onError 没有调用方法。

我做错了什么?它必须呼叫 至少没有任何相关的错误 LogCat .

我已经签入调试器应用程序检索授权代码,它不是 null .
