改装：预计BEGIN_OBJECT，但是STRING

我有这样的JSON文件http://sawbo-illinois.org/mobileApp.php。我创建的对象为：改装：预计BEGIN_OBJECT，但是STRING

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; 
    } 
}

但我得到改造失败响应回电话，因为我跟着这个样子。我的问题在哪里？

我完整的代码是：

改造接口：

public interface ServiceAPI { 

    @GET("mobileApp.php") 
    Call<Video> getVideoDetails(); 
}

可能回调和转换过程：在

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();

你是如何解析json？共享代码 – AwaisMajeed

与转换器-GSON作为这样的：'改造改型=新Retrofit.Builder（） .baseUrl（ “http://sawbo-illinois.org”） .addConverterFactory（GsonConverterFactory.create（）） .build（）; ServiceAPI服务= retrofit.create（ServiceAPI.class）; final致电

as this ????这是哪里？ – AwaisMajeed

您的代码会工作的API调用，如果服务器响应将是一个JSON文件。响应目前是一个HTML文件，使混乱，如果查看它的网络浏览器（同样的内容是双向的网络浏览器，并记录在一个OkHttpClient实例）：

您应该只是修复mobileApp.php脚本并删除所有与JSON结构无关的内容。如果响应Content-Type标题将被设置为JSON MIME类型：What is the correct JSON content type?将会很好。

谢谢你的帮助。 – Mahsa

我认为你需要添加斜杠（/）baseUrl这样结束：

这样创建界面您的来电：

public interface ApiWebServices { 
    @GET() 
    Call<Video> getVideoDetails(@Url String url); 
}

然后让就像你上面

Call<Video> call = service.getVideoDetails("http://sawbo-illinois.org/mobileApp.php"); 
call.enque(..);

我分享了完整的代码，我按照你的说法进行了操作，但在这种情况下没有查询。 – Mahsa

@Mahsa当没有端点时，您可以在您的Retrofit调用参数中传递整个url。 –

感谢您的回应，我已按照您的指南进行操作，但仍得到相同的错误“期望的BEGIN_OBJECT，但在第3行第1列路径处为STRING”。服务器有可能发生错误吗？我不熟悉服务器开发。 – Mahsa

if (response.code() == 200) {   
    String result = response.body().string(); 
    Gson gson = new Gson(); 
    pojo = gson.fromJson(result, PojoClass.class); 
}
