通过Retrofit2 POST请求在JSONObject中获取JSONObject

implementation 'com.squareup.retrofit2:retrofit:2.x.x'
implementation 'com.squareup.retrofit2:converter-gson:2.x.x'

public interface ApiService {
    @POST("your_api_endpoint")
    Call<JSONObject> postData(@Body JSONObject requestBody);
}

// 创建Retrofit实例
Retrofit retrofit = new Retrofit.Builder()
        .baseUrl("your_base_url")
        .addConverterFactory(GsonConverterFactory.create())
        .build();

// 创建ApiService实例
ApiService apiService = retrofit.create(ApiService.class);

// 创建请求体JSONObject
JSONObject requestBody = new JSONObject();
try {
    requestBody.put("key1", "value1");
    requestBody.put("key2", "value2");
} catch (JSONException e) {
    e.printStackTrace();
}

// 发起POST请求
Call<JSONObject> call = apiService.postData(requestBody);
call.enqueue(new Callback<JSONObject>() {
    @Override
    public void onResponse(Call<JSONObject> call, Response<JSONObject> response) {
        if (response.isSuccessful()) {
            JSONObject result = response.body();
            // 在这里处理返回的JSONObject
        } else {
            // 请求失败
        }
    }

    @Override
    public void onFailure(Call<JSONObject> call, Throwable t) {
        // 请求失败
    }
});
