直接在我的浏览器中输入(删除了appId)
http://api.openweathermap.org/data/2.5/weather?q=37421&appid=xxxx
我得到了这个预期的回应
{“coord”:{“lon”:73,“lat”:31.32},“weather”:[{“id”:800,“main”:“Clear”,“description”:“晴朗的天空” “图标”: “01N”}], “基”: “站”, “主”:{ “温度”:286.471, “压力”:1007.05, “湿度”:86, “temp_min”:286.471,“temp_max “:286.471,” sea_level “:1028.03,” grnd_level “:1007.05},” 风 “:{” 速度 “:3.01,” DEG “:252.003},” 云 “:{” 所有 “:0},” DT” :1516458282,“sys”:{“message”:0.0035,“country”:“PK”,“sunrise”:1516413964,“sunset”:1516451547},“id”:1179400,“name”:“Chak 247 RB Miani ”, “鳕鱼”:200}
我想要的只是纬度和经度坐标。
这是我的模特
public class CoordObject {
private String lat;
private String lon;
public CoordObject(
String lat,
String lon({
this.lat =lat;
this.lon =lon;
}
public String getLat(){
return lat;
}
public String getLon(){
return lon;
}
}
和我的界面
public interface OwmInterface {
@GET("/data/2.5/weather")
Call<CoordObject> getCoord(@Query("q") String zipCode,
@Query("appid") String appId);
}
和我的活动
final String BASE_URL = "https://api.openweathermap.org/";
final String API_KEY_OWM = "xxxx";
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(BASE_URL)
.addConverterFactory(GsonConverterFactory.create())
.build();
OwmInterface request = retrofit.create(OwmInterface.class);
Call<CoordObject> call = request.getCoord(
"37421",
API_KEY_OWM
);
call.enqueue(new Callback<CoordObject>() {
@Override
public void onResponse(Call<CoordObject> call, Response<CoordObject> response){
CoordObject coordObjectResponse = response.body();
Toast.makeText(MainActivity.this, coordObjectResponse.getLat(), Toast.LENGTH_LONG).show();
Toast.makeText(MainActivity.this, coordObjectResponse.getLon(), Toast.LENGTH_LONG).show();
}
@Override
public void onFailure(Call<CoordObject> call, Throwable t) {
Toast.makeText(MainActivity.this, "failed" +t, Toast.LENGTH_SHORT).show();
}
});
我得到了回复但是祝酒词显示为空。
答案 0 :(得分:1)
根目录中有一个包含CoordObject
的对象
您应该再创建一个类:
public class RootObject {
private CoordObject coord;
public RootObject(CoordObject coord){
this.coord = coord
}
public CoordObject getCoordinates(){
return coord;
}
}
现在您的界面应该返回RootObject
:
@GET("/data/2.5/weather")
Call<RootObject> getCoord(@Query("q") String zipCode,
@Query("appid") String appId);
同时检查lat
和lon
是否来自double
,而不是String
。
