Question

我的服务器返回简单的Json结果，如下所示，

{"message":"Upload Success.!"}

我正在尝试将结果导入Retrofit Model类

public class MyResponse {
    @SerializedName("message")
    String message;
}

我的界面类在这里

public interface MyService {

    @Multipart
    @POST("/")
    public retrofit2.Call<MyResponse> saveFile(@Part("filename") String fileName, @Part("photo") RequestBody photo);
}

这是我尝试获取结果的方式

Gson gson = new GsonBuilder()
                            .setLenient()
                            .create();

Retrofit retrofit = new Retrofit.Builder().baseUrl("http://xxxxxxx.com/fileupload.php/").addConverterFactory(GsonConverterFactory.create(gson)).build();

MyService service = retrofit.create(MyService.class);

retrofit2.Call<MyResponse> call = service.saveFile(filename, requestbody);

retrofit2.Response<MyResponse> response = call.execute();

但我无法将结果绑定到MyResponse类

结果

我想我在这里犯了一个小错误。有人能识别出来吗？

Answer 1

根据改进文档，您的基本网址应仅包含您案例中网址的第一部分：基本网址应为"http://xxxxxxx.com/ 并在帖子中添加其他部分，如@POST("fileupload.php/")。试一试也许它会对你有用。

谢谢！

Answer 2

请检查PostMan中的响应，如果在邮递员中你收到的回复与你说的相同，那么这意味着在你的应用程序中你得到错误响应，这是字符串格式，这就是你得到这种类型不匹配异常的原因。
