kotlin - 无法在 kotlin 中将 AsyncTask 转换为 Retrofit2

Question

我正在尝试将以下代码(java)转换为在kotlin中使用retrofit2发布请求，但是，我发现retrofit2文档很难理解。我尝试使用@POST 并发送请求但失败。如果您能给我一些提示或示例，那将是一个很大的帮助。我很乐意听到像您这样的专业人士的意见!

这是我要发送的请求类型

curl -X POST https://api.a3rt.recruit-tech.co.jp/talk/v1/smalltalk \
-F "apikey=AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA" \
-F "query=test"

以下是我要转换为retrofit2的实际代码

public class TalkAysncTask extends AsyncTask<String, String, String> {

    private static final String API_KEY = YOUR API KEY;
    private static final String API_URL = 
        "https://api.a3rt.recruit-tech.co.jp/talk/v1/smalltalk";

    interface Callback{
        void onReturn(String s);
    }

    private Callback callback;

    TalkAysncTask(Context context){
        callback = (Callback) context;
    }

    @Override
    protected String doInBackground(String... params) {

        RequestBody body = new FormBody.Builder()
                .add("apikey", API_KEY)
                .add("query", params[0])
                .build();

        Request request = new Request.Builder()
                .url(API_URL)
                .post(body)
                .build();

        OkHttpClient client = new OkHttpClient.Builder()
                .build();

        try{
            Response response = client.newCall(request).execute();

            return response.body().string();
        }catch (IOException e){
            e.printStackTrace();
        }

        return null;
    }

    @Override
    protected void onPostExecute(String s) {
        Log.d("debug", s);
        callback.onReturn(s);
    }
}

我也想知道如何获得以下类型的响应

{
    status: 200,
    message: "ok",
    results: [{
        perplexity: 2.3688167429546714,
        reply: "tested"
    }],
}

我尝试使用以下代码但没有成功

interface AiClient {
    @FormUrlEncoded
    @POST("/talk/v1/smalltalk")
    fun request(@Field("apikey") apiKey: String,
                @Field("query") query: String?): Call<ApiResponse>

    companion object {
        fun create(): AiClient {
            val retrofit = retrofit2.Retrofit.Builder()
                    .baseUrl("https://api.a3rt.recruit-tech.co.jp")
                    .addConverterFactory(GsonConverterFactory.create())
                    .build()
            return retrofit.create(AiClient::class.java)
        }
    }
}

创建模型类:

class ApiResponse(var status:Int, var message:String, var results:MutableList<Results>){
class Results(var perplexity:Double,var reply:String)
}

更改您的 AiClient:

interface  AiClient {
@FormUrlEncoded
@POST("talk/v1/smalltalk")
fun request(@Field("apikey") apiKey: String,
            @Field("query") query: String?): retrofit2.Call<ApiResponse>

companion object {
    fun create(): AiClient {
        val retrofit = retrofit2.Retrofit.Builder()
                .baseUrl("https://api.a3rt.recruit-tech.co.jp/")
                .addConverterFactory(GsonConverterFactory.create())
                .build()
        return retrofit.create(AiClient::class.java)
    }
}
}

调用 Api:

AiClient.create().request("yourkey","yourquery").enqueue(object :Callback<ApiResponse> {
        override fun onFailure(call: Call<ApiResponse>?, t: Throwable?) {
        }

        override fun onResponse(call: Call<ApiResponse>, response: Response<ApiResponse>) {
            if (response.isSuccessful){
                var result=response.body()
                if (result!=null){
                    result.message
                }


            }

        }
    })
}
