在Android中获得400 HTTP响应的响应正文？

public interface ApiService {
    @GET("your/endpoint")
    Call<ResponseBody> getResponse();
}

Retrofit retrofit = new Retrofit.Builder()
        .baseUrl("https://your-api-url.com/")
        .addConverterFactory(GsonConverterFactory.create())
        .build();

ApiService apiService = retrofit.create(ApiService.class);

Call<ResponseBody> call = apiService.getResponse();

call.enqueue(new Callback<ResponseBody>() {
    @Override
    public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
        if (response.code() == 400) {
            try {
                String errorResponseBody = response.errorBody().string();
                // 处理响应正文
            } catch (IOException e) {
                e.printStackTrace();
            }
        } else {
            // 处理其他状态码
        }
    }

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