我要做一个基于Android studio的多城市切换+短时预警天气预报app，我的天气API是在https://www.seniverse.com/products这个网站中获取的，其中我的密钥（私钥）是SH8NroqLlNNwwg323，但是我运行之后没有获取到实时数据，我要怎么做，请给我完整代码及完善步骤
这个是我的接口ApiService代码
package com.example.myapplication.network;
import retrofit2.Call;
import retrofit2.http.GET;
import retrofit2.http.Query;
public interface ApiService {
// 心知天气API基础地址
String BASE_URL = "https://api.seniverse.com/v3/";
// 图片中的API密钥（公钥+私钥）
String PUBLIC_KEY = "PVKLD84OHMbGx9iQG";
String PRIVATE_KEY = "SH8NroqLINNwg323";
/**
* 获取实时天气
* @param location 城市名称/ID（如：beijing、101010100）
* @param language 语言（zh-Hans=中文）
* @param unit 单位（c=摄氏度）
* @param key 公钥
* @return 实时天气响应
*/
@GET("weather/now.json")
Call<RealTimeResponse> getRealTimeWeather(
@Query("location") String location,
@Query("language") String language,
@Query("unit") String unit,
@Query("key") String key
);
/**
* 获取7天预报
* @param location 城市名称/ID
* @param language 语言
* @param unit 单位
* @param key 公钥
* @return 7天预报响应
*/
@GET("weather/daily.json")
Call<DailyForecastResponse> get7DayForecast(
@Query("location") String location,
@Query("language") String language,
@Query("unit") String unit,
@Query("key") String key,
@Query("start") int start, // 开始天数（0=今天）
@Query("days") int days // 预报天数（7=7天）
);
// 实时天气响应模型
class RealTimeResponse {
private Results[] results;
public Results[] getResults() { return results; }
public static class Results {
private Location location;
private Now now;
private String last_update;
public Location getLocation() { return location; }
public Now getNow() { return now; }
public String getLast_update() { return last_update; }
}
public static class Location {
private String id;
private String name;
private String country;
private String path;
public String getId() { return id; }
public String getName() { return name; }
public String getCountry() { return country; }
public String getPath() { return path; }
}
public static class Now {
private String text;
private String code;
private String temperature;
private String humidity;
private String wind_direction;
private String wind_speed;
private String wind_scale;
public String getText() { return text; }
public String getCode() { return code; }
public String getTemperature() { return temperature; }
public String getHumidity() { return humidity; }
public String getWind_direction() { return wind_direction; }
public String getWind_speed() { return wind_speed; }
public String getWind_scale() { return wind_scale; }
}
}
// 7天预报响应模型
class DailyForecastResponse {
private Results[] results;
public Results[] getResults() { return results; }
public static class Results {
private Location location;
private Daily[] daily;
private String last_update;
public Location getLocation() { return location; }
public Daily[] getDaily() { return daily; }
public String getLast_update() { return last_update; }
}
public static class Location {
private String id;
private String name;
public String getId() { return id; }
public String getName() { return name; }
}
public static class Daily {
private String date;
private String text_day;
private String code_day;
private String text_night;
private String code_night;
private String high;
private String low;
private String wind_direction;
private String wind_scale;
public String getDate() { return date; }
public String getText_day() { return text_day; }
public String getCode_day() { return code_day; }
public String getText_night() { return text_night; }
public String getCode_night() { return code_night; }
public String getHigh() { return high; }
public String getLow() { return low; }
public String getWind_direction() { return wind_direction; }
public String getWind_scale() { return wind_scale; }
}
}
}
这个是我的RetrofitClient类代码
package com.example.myapplication.network;
import retrofit2.Retrofit;
import retrofit2.converter.gson.GsonConverterFactory;
public class RetrofitClient {
private static RetrofitClient instance;
private final ApiService apiService;
private RetrofitClient() {
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(ApiService.BASE_URL)
.addConverterFactory(GsonConverterFactory.create())
.build();
apiService = retrofit.create(ApiService.class);
}
public static synchronized RetrofitClient getInstance() {
if (instance == null) {
instance = new RetrofitClient();
}
return instance;
}
public ApiService getApiService() {
return apiService;
}
}
