Retrofit2 POST请求，数据响应中的空值

public class ResponseData {
    @SerializedName("name")
    @Nullable
    private String name;

    // 其他属性...

    public String getName() {
        return name;
    }

    // 其他getter和setter方法...
}

public interface ApiService {
    @POST("api/endpoint")
    Call<ResponseData> postData(@Body RequestBody requestBody);
}

// 创建Retrofit实例
Retrofit retrofit = new Retrofit.Builder()
        .baseUrl("https://api.example.com/")
        .addConverterFactory(GsonConverterFactory.create())
        .build();

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

// 创建请求体
RequestBody requestBody = new MultipartBody.Builder()
        .setType(MultipartBody.FORM)
        .addFormDataPart("param1", "value1")
        .build();

// 发起POST请求
Call<ResponseData> call = apiService.postData(requestBody);
call.enqueue(new Callback<ResponseData>() {
    @Override
    public void onResponse(Call<ResponseData> call, Response<ResponseData> response) {
        if (response.isSuccessful()) {
            ResponseData responseData = response.body();
            if (responseData != null) {
                String name = responseData.getName();
                if (name != null && !name.isEmpty()) {
                    // 处理非空值
                } else {
                    // 处理空值
                }
            }
        } else {
            // 处理请求失败的情况
        }
    }

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