调用第三方接口

利用OkHttp调用第三方天气接口

1.获取第三方接口api

private final String WEATHER_API_URL = "https://cn.apihz.cn/api/tianqi/tqybbaiducn.php?id="+id+"&key="+id+"&sheng=省份&place=城市";

2.创建OkHttpclient对象

private final OkHttpClient client = new OkHttpClient();

3.返回结果

public Map<String, String> getWeatherAnePm() throws Exception {
    Map<String, String> weatherAndPm = new HashMap<>();
    // 天气请求
    Request request = new Request.Builder().url(WEATHER_API_URL).build();
    try (Response response = client.newCall(request).execute()) {
        if (response.isSuccessful()) {
            ObjectMapper objectMapper = new ObjectMapper();
            JsonNode jsonNode = objectMapper.readTree(response.body().string());
            String weather = String.valueOf(jsonNode.get("result").get("now").get("temp"));
            weatherAndPm.put("weather", weather);
        } else {
            weatherAndPm.put("weather", "天气超时");
        }
    }
