改造Android基本和简单的问题 [英] Retrofit Android basic and simple issue

问题描述

我的服务器返回如下简单的 Json 结果，

My server returns simple Json result like below,

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

我正在尝试将结果放入 Retrofit Model 类

I am trying to get the result into Retrofit Model class

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

我的接口类在这里

public interface MyService {

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

这就是我尝试获取结果的方式

this is how i try to fetch the result

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

But i cannot bind the result to the MyResponse class

结果吧

我想我在这里犯了一个小错误.有人可以识别吗?

I guess I'm doing small mistake here. can someone identify that please ?

推荐答案

根据改造文档，在您的情况下，您的基本 url 应该只包含 url 的第一部分:基本网址应该是 "http://xxxxxxx.com/并像这样在 Post 中添加另一部分 @POST("fileupload.php/").试一试也许它对你有用.

According to retrofit documentation your base url should only consist the first part of url in your case: Base url should be "http://xxxxxxx.com/ and add the other part in Post like this @POST("fileupload.php/"). Give it a try maybe it will work for you.

谢谢！
