改造响应失败

Question

我想了解每一个我的回答是失败的时候，我是如何工作的改进，但即使使用GitHub的API，但仍然是我的响应失败了，我做错了什么 我很困惑

链接

http://api.openweathermap.org/data/2.5/weather?q=Spakane,Us&appid=api_key 

接口类

@GET("data/2.5/weather") 
Call<List<Weather>> getWeatherData(@Query("q") String cityName,@Query("appid") String apikey); 

MainActivity

private final String BASE_URL = "http://api.openweathermap.org/"; 

Retrofit retrofit = new Retrofit.Builder() 
       .baseUrl(BASE_URL) 
       .addConverterFactory(GsonConverterFactory.create()) 
       .build(); 

     RestApi api = retrofit.create(RestApi.class); 


     final Call<List<Weather>> weather = api.getWeatherData("rawalpindi",API_KEY); 

     final ProgressDialog pg = new ProgressDialog(this); 
     pg.setTitle("Downloading"); 
     pg.setMessage("Please Wait ....."); 
     pg.show(); 

     weather.enqueue(new Callback<List<Weather>>() { 
      @Override 
      public void onResponse(Call<List<Weather>> call, Response<List<Weather>> response) { 

       pg.dismiss(); 

       Log.d(TAG, "onResponse: "+response.isSuccessful()); 

       Log.d(TAG, "onResponse: "+response.body().get(0).getClouds()); 

      } 

      @Override 
      public void onFailure(Call<List<Weather>> call, Throwable t) { 

       Log.d(TAG, "onFailure: Failed :("); 
       Log.d(TAG, "onResponseFailed: "+call.request().url()); 
       pg.dismiss(); 
      } 
     }); 

登录

D/MainActivity: onFailure: Failed :(
D/MainActivity: onResponseFailed: http://api.openweathermap.org/data/2.5/weather?q=rawalpindi&appid=api_key 

抛出消息

Expected BEGIN_ARRAY but was BEGIN_OBJECT at line 1 column 2 path $ 

Answer 1

您的回答不是清单，只是一个对象。使用拦截器来查看响应。

作为示例，从Call<List<Weather>>您应该只使用Call<Weather>。

Answer 2

打印抛出错误，如 “Log.e（TAG， ”NET_ERROR：“ + t.toString（））;”。这可能是网络问题。
