我正在开发一个 Kotlin 多平台应用程序，我使用 Ktor 来进行网络调用，并使用 SqlDelite 来管理本地数据源。
因此，当您创建 KMM 项目时，我尝试实现与构建 Android Studio 相同的结构。
我的问题是我用来异步连接的 api，我需要传递两个标头才能在其中进行身份验证。我尝试在我的 HttpClient 中使用标头，并在我的客户端的 get 方法中使用参数。
我不知道这是正确的方法，还是看起来不是。
关于我的后端设置有以下类：
UnsplashApi.kt
class UnsplashApi(private val client: HttpClient = ktorClient) {
suspend fun getPets(): List<UnsplashPhoto> = client.get(UNSPLASH_URL){
parameter("query", "cats")
parameter("page", 1)
parameter("per_page", 10)
}
//TODO("Actualizar el endpoint para incorporar la funcionalidad de buscar por nombre")
suspend fun getPetsByName(pet: String): List<UnsplashPhoto> = client.get(UNSPLASH_URL){
headers{
append(HttpHeaders.Accept, "v1")
append("Authorization:","Client-ID $CLIENT_ID")
}
parameter("query", pet)
parameter("page", 1)
parameter("per_page", 10)
}
}
internal val kotlinxSerializer = KotlinxSerializer(
Json(
JsonConfiguration(isLenient = true, ignoreUnknownKeys = true)
)
)
internal val ktorClient = HttpClient {
defaultRequest {
header("Authorization:", "Client-ID $CLIENT_ID")
header("Accept-Version:","v1")
}
install(JsonFeature) {
serializer = kotlinxSerializer
}
install(Logging) {
logger = Logger.DEFAULT
level = LogLevel.ALL
}
}
PetsRepository.kt
internal expect fun cache(): PetsDatabase
class PetsRepository(
private val api: UnsplashApi,
private val queries: PetsDBQueries = cache().petsDBQueries
) {
constructor() : this(api = UnsplashApi())
/**
* If [force] is set to true, attempt to load data from remote api.
* If remote api is not available. throw [RefreshDataException]
*
* If [force] is set to false, attempt to load data from local cache.
* If local cache is not available, propagate the exception encountered
*/
fun fetchMembersAsFlow(force: Boolean): Flow<List<Pets>> {
return if (force) getMembersFromRemote() as Flow<List<Pets>> else getMembersFromCache()
}
private fun cacheMembers(pets: List<Pets>) {
queries.deleteAll()
pets.forEach { pet ->
queries.insertPet(
pet.id,
pet.description,
pet.url,
pet.email
)
}
}
/**
* Retorna un Flow con una lista de Pets, y guardando en la BD local
* los pets recuperados de la llamada de red.
*/
private fun getMembersFromRemote(): Flow<List<UnsplashPhoto>> {
println("Getting members from remote")
return flow {
val unsplashPhotos = api.getPets()
Log.d("info", "size pets llamada de red: ${unsplashPhotos.size}")
Log.d("info", "pets $unsplashPhotos")
//TODO(""Convert UnplashPhoto o Pets")
var pets : List<Pets> = unsplashPhotos.map {
Pets(it.id!!.toLong(), it.description!!, it.urls.full, it.user.name)
}
cacheMembers(pets)
emit(api.getPets())
}
.catch { error(RefreshDataException()) }
.flowOn(applicationDispatcher)
}
private fun getMembersFromCache(): Flow<List<Pets>> {
println("Getting members from cache")
fun loadMembers() = queries.selectAll()
.executeAsList()
.map { Pets(id = it.id, description = it.description, url = it.url, email = it.emailUser) }
return flow { emit(loadMembers()) }
.catch { error(RefreshDataException()) }
.flowOn(applicationDispatcher)
}
}
关于我的 androidApp 文件夹分类：
PetsViewModel.kt
class PetsViewModel(
private val repository: PetsRepository
) : ViewModel() {
private val _pets = MutableLiveData<List<Pets>>()
val pets: LiveData<List<Pets>> = _pets
private val _error = MutableLiveData<Throwable>()
val error: LiveData<Throwable> = _error
private val _isRefreshing = MutableLiveData<Boolean>()
val isRefreshing: LiveData<Boolean> = _isRefreshing
init {
loadPets()
}
fun loadPets(force: Boolean = false) {
viewModelScope.launch {
repository.fetchMembersAsFlow(force)
.onStart {
_isRefreshing.value = true
}.onCompletion {
_isRefreshing.value = false
}.catch {
_error.value = it
Log.d("info", "STACKTRACE: ${it.stackTrace.contentToString()} + ${it.cause}")
}.collect {
_pets.value = it
}
}
}
}
宠物适配器.kt
class PatsAdapter(var pets: List<Pets>) : RecyclerView.Adapter<PatsAdapter.MemberViewHolder>() {
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): MemberViewHolder {
val itemView =
LayoutInflater.from(parent.context).inflate(R.layout.list_item_member, parent, false)
return MemberViewHolder(itemView)
}
override fun getItemCount() = pets.size
override fun onBindViewHolder(holder: MemberViewHolder, position: Int) {
holder.bind(pets[position])
}
class MemberViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
fun bind(pet: Pets) {
Picasso.get().load(pet.url).into(itemView.memberAvatar)
itemView.tvItemDescription.text = pet.description
itemView.tvItemAutor.text = pet.email
}
}
}
MainActivity.kt
class MainActivity : AppCompatActivity() {
private val repository by lazy {
(application as Application).membersRepository
}
private val viewModel by lazy { PetsViewModel(repository) }
private lateinit var adapter: PatsAdapter
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(layout.activity_main)
platformMessage.text = createPlatformMessage()
setupRecyclerView()
viewModel.pets.observe(this, Observer {
if (it.isEmpty()) {
Toast.makeText(this, R.string.empty_cache, Toast.LENGTH_LONG).show()
} else {
showData(it)
}
})
viewModel.error.observe(this, Observer {
showError(it)
})
viewModel.isRefreshing.observe(this, Observer {
pullToRefresh.isRefreshing = it
})
pullToRefresh.setOnRefreshListener {
viewModel.loadPets(force = true)
}
}
private fun showData(pets: List<Pets>) {
adapter.pets = pets
adapter.notifyDataSetChanged()
}
private fun showError(error: Throwable) {
val errorMessage = when (error) {
is RefreshDataException -> getString(string.refresh_data_error)
else -> getString(string.unknown_error)
}
Toast.makeText(this, errorMessage, Toast.LENGTH_LONG).show()
}
private fun setupRecyclerView() {
membersRecyclerView.layoutManager = LinearLayoutManager(this)
adapter = PatsAdapter(emptyList())
membersRecyclerView.adapter = adapter
}
}
应用程序.kt
class Application : Application() {
val membersRepository by lazy { PetsRepository() }
override fun onCreate() {
super.onCreate()
appContext = this
if (BuildConfig.DEBUG) {
Timber.plant(Timber.DebugTree())
}
}
}
我不包括 sqlDelite 的部分，因为与这个问题的主要目标无关，这是 Api.kt 类的结构，其中 Ktor 用于建立网络连接。

像这样更改我的 api.kt 类后：
class UnsplashApi(private val client: HttpClient = ktorClient) {
suspend fun getPets(): List<UnsplashPhoto> = client.get(UNSPLASH_URL){
//parameter("client_id", CLIENT_ID)
parameter("query", "cats")
parameter("page", 1)
parameter("per_page", 10)
}
//TODO("Actualizar el endpoint para incorporar la funcionalidad de buscar por nombre")
suspend fun getPetsByName(pet: String): List<UnsplashPhoto> = client.get(UNSPLASH_URL){
parameter("query", pet)
parameter("page", 1)
parameter("per_page", 10)
}
}
internal const val UNSPLASH_URL = "https://api.unsplash.com/search/photos"
private const val CLIENT_ID : String = ....
internal val kotlinxSerializer = KotlinxSerializer(
Json(
JsonConfiguration(isLenient = true, ignoreUnknownKeys = true)
)
)
internal val ktorClient = HttpClient {
defaultRequest {
header("Accept-Version","v1")
header("Authorization", "Client-ID $CLIENT_ID")
}
install(JsonFeature) {
serializer = kotlinxSerializer
}
install(Logging) {
logger = Logger.DEFAULT

}
}
我开始在 logcat 中得到这个：
