改裝：預計BEGIN_OBJECT，但是STRING

我有這樣的JSON文件http://sawbo-illinois.org/mobileApp.php。我創建的對象爲：改裝：預計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; 
    } 
}

但我得到改造失敗響應回電話，因爲我跟着這個樣子。我的問題在哪裏？

我完整的代碼是：

改造接口：

public interface ServiceAPI { 

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

可能回調和轉換過程：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？共享代碼 – AwaisMajeed

與轉換器-GSON作爲這樣的：'改造改型=新Retrofit.Builder（） .baseUrl（「http://sawbo-illinois.org」） .addConverterFactory（GsonConverterFactory.create（）） .build（）; ServiceAPI服務= retrofit.create（ServiceAPI.class）; final致電

as this ????這是哪裏？ – AwaisMajeed

您的代碼會工作的API調用，如果服務器響應將是一個JSON文件。響應目前是一個HTML文件，使混亂，如果查看它的網絡瀏覽器（同樣的內容是雙向的網絡瀏覽器，並記錄在一個OkHttpClient實例）：

您應該只是修復mobileApp.php腳本並刪除所有與JSON結構無關的內容。如果響應Content-Type標題將被設置爲JSON MIME類型：What is the correct JSON content type?將會很好。

謝謝你的幫助。 – Mahsa

我認爲你需要添加斜槓（/）baseUrl這樣結束：

這樣創建界面您的來電：

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

然後讓就像你上面

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

我分享了完整的代碼，我按照你的說法進行了操作，但在這種情況下沒有查詢。 – Mahsa

@Mahsa當沒有端點時，您可以在您的Retrofit調用參數中傳遞整個url。 –

感謝您的迴應，我已按照您的指南進行操作，但仍得到相同的錯誤「期望的BEGIN_OBJECT，但在第3行第1列路徑處爲STRING」。服務器有可能發生錯誤嗎？我不熟悉服務器開發。 – Mahsa

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