我有如下JSON文件http://sawbo-illinois.org/mobileApp.php . 我已将对象创建为:
public class Video {
public List<all> all;
public List<String>Language;
public List<String>Country;
public List<String>Topic;
public class all{
public String id;
public String Country;
public String Language;
public String Topic;
public String Title;
public String Video;
public String Videolight;
public String Description;
public String Image;
}
}
但是当我像这样跟着的时候,我得到了改造失败的回应。我的问题在哪里?
我的完整代码是:
改造界面:
public interface ServiceAPI {
@GET("mobileApp.php")
Call<Video> getVideoDetails();
}
可能回调和转换过程:
Retrofit retrofit = new Retrofit.Builder()
.baseUrl("http://sawbo-illinois.org/")
.addConverterFactory(GsonConverterFactory.create())
.build();
ServiceAPI service = retrofit.create(ServiceAPI.class);
final Call<Video> call = service.getVideoDetails();
if (response.code() == 200) {
String result = response.body().string();
Gson gson = new Gson();
pojo = gson.fromJson(result, PojoClass.class);
}
我认为您需要在baseUrl的末尾添加斜杠(/),如下所示:
使用如下界面创建调用:
public interface ApiWebServices {
@GET()
Call<Video> getVideoDetails(@Url String url);
}
然后像上面一样进行API调用
Call<Video> call = service.getVideoDetails("http://sawbo-illinois.org/mobileApp.php");
call.enque(..);
如果服务器响应是JSON文档,那么代码就可以工作。当前的响应是一个HTML文档,如果在web浏览器中查看它,会造成混淆(web浏览器和登录到OkHttpClient实例的内容相同):

您应该只修复mobile eApp.php
脚本并删除所有与JSON结构无关的内容。如果响应Content-Type
标头设置为JSON MIME类型会很好:什么是正确的JSON内容类型?。
