Parse model from data object-CodePudding

My API returns a response that looks like this:

{
    status: number,
    message?: string,
    data?: T,
}

So in a retrofit service I have to wrap all return values in this response class:

data class Response<T>(val status: Int, val message: String?, val data: T?)

interface MyService {
    @GET("user")
    suspend fun getUser(id: String): Response<User>
}

Now the question: How can make it return a class without wrapping a return value?

suspend fun getUser(id: String): User

CodePudding user response：

The way you are making the interface you'll have to make multiple functions return multiple return objects. Try Making a Generic Response interface and then Handle the response in your code. Make your interface like this :

@GET
suspend fun getUser(@Url endpoint: String,id: String): Call<ResponseBody>

Then in your Response Function Use it like :

override fun onResponse(call : Call<ResponseBody>,response: Response<ResponseBody>) {
        //Parse your object here
        String responseBody = response.body().string();
        JSONObject json = new JSONObject(responseBody);
        val responseObject : User = Gson().fromJson(
                    json.optJSONObject("data")?.toString(),
                    User::class.java)
    }

make sure to implement Gson in your app gradle.

You can adapt return types using Retrofit's CallAdapter and CallAdapter.Factory. Knowing this should help you find some code examples online, which you can adapt to your specific use case.
