POST请求和GET请求差不多，主要它多了许多的参数，于是我们用的最多的也是通过Map把值传递进去，这个和GET直接在后面追加参数的方式不同！
public class WeatherRetrofitPost {
interface WeatherInteface {
String HOST = "http://op.juhe.cn/onebox/weather/";
@POST("query")
Call<JSONObject> postJSONObject(@QueryMap Map<String,String> map);
}
public static void doPost(Map<String,String> map,Callback<JSONObject> callback) {
Retrofit build = new Retrofit.Builder().baseUrl(WeatherInteface.HOST).addConverterFactory(JsonConverterFactory.create()).build();
WeatherInteface inteface = build.create(WeatherInteface.class);
inteface.postJSONObject(map).enqueue(callback);
}
}
然后在主页请求
private void doPost() {
Map<String,String> map = new HashMap<>();
map.put("cityname","北京");
map.put("key", "11c39e939a9a32caa5613f9d0e3cf598");
WeatherRetrofitPost.doPost(map, new Callback<JSONObject>() {
@Override
public void onResponse(Call<JSONObject> call,Response<JSONObject> response) {
tvMsg.setText(response.body().toString());
}
@Override
public void onFailure(Call<JSONObject> call, Throwable t) {}
});
}
