I expect the response body to return a value when the status code is not successful because when I try it on Postman it actually gave me a message or one of the attributes of the JSON Array. But, when I try to store the response body into a variable, it always returns null. I don't know why
Here's the ApiService
@POST("register")
fun registerAkun(
@Body registrasiAkun: RegistrasiBodyRequest
): Call<RegistrasiResponse>
Here's the method inside RemoteDataSource
override fun registrasiAkun(registrasiAkun: RegistrasiBodyRequest): LiveData<ApiResponse<RegistrasiResponse>> {
val result = MutableLiveData<ApiResponse<RegistrasiResponse>>()
result.postValue(ApiResponse.Loading)
EspressoIdlingResource.increment()
val client = apiService.registerAkun(registrasiAkun)
client.enqueue(object : Callback<RegistrasiResponse> {
override fun onResponse(
call: Call<RegistrasiResponse>,
response: Response<RegistrasiResponse>
) {
val data = response.body()
Log.d("RemoteDataSource0", "$data")
if (response.isSuccessful) {
result.postValue(data?.let {
ApiResponse.Success(data)
})
} else {
data?.let {
result.postValue(ApiResponse.Error(it.message.toString()))
} ?: run {
Log.d("RemoteDataSource", "$data dan $response")
}
}
}
override fun onFailure(call: Call<RegistrasiResponse>, t: Throwable) {
Log.d("RemoteDataSourceFailure", t.message.toString())
result.postValue(ApiResponse.Error(t.message.toString()))
}
})
return result
}
Model:
data class RegistrasiResponse(
@SerializedName("message")
val message: String? = null,
@SerializedName("customer")
val customer: CustomerResponse? = null
)
data class CustomerResponse(
@field:SerializedName("nama_customer")
val namaCustomer: String?,
@field:SerializedName("id_customer")
val idCustomer: Int?,
@field:SerializedName("email_customer")
val emailCustomer: String?
)
And here's the Log

I/okhttp.OkHttpClient: <-- END HTTP (39-byte body)

And here's what I expect or these
Whenever the response is successful, it returns this
RegistrasiResponse(message=Registrasi Sukses, customer=CustomerResponse(namaCustomer=aaaaaa, idCustomer=50, emailCustomer=aaaaa@mail.com))
CodePudding user response:
You should obtain the body from errorBody()
instead of body()
for case !isSuccessful
.
EDIT:
You may need an object to hold the message
. e.g.
data class ErrorResponse(
val message: String? = null
)
and inside onResponse()
will looks like this
if (response.isSuccessful) {
result.postValue(response.body()?.let {
ApiResponse.Success(it)
})
} else {
response.errorBody()?.string()?.let {
val error = Gson().fromJson(it, ErrorResponse::class.java)
result.postValue(ApiResponse.Error(error.message.orEmpty()))
} ?: run {
Log.d("RemoteDataSource", "${response.errorBody()?.string()} dan $response")
}
}
CodePudding user response:
Finally found the solution to get the message string by converting it
response.errorBody()?.let { errorBody ->
try {
val jsonObject = JSONObject(errorBody.string())
val error = jsonObject.getString("message")
result.postValue(ApiResponse.Error(error))
} catch (e: Exception) {
result.postValue(ApiResponse.Error("${e.message}"))
}
}
