百度提供天气预报查询接口API,可以根据经纬度/城市名查询天气情况。
根据经纬度/城市名查询天气的结果
http://api.map.baidu.com/telematics/v3/weather?location=北京&output=json&ak=yourkey
百度ak申请地址:http://lbsyun.baidu.com/apiconsole/key
AK申请到以后,就可以直接用这个接口了。
参数类型 | 参数名称 | 是否必须 | 具体描述 |
---|---|---|---|
String | ak | true | 开发者密钥 |
String | sn | false | 若用户所用ak的校验方式为sn校验时该参数必须。 |
String | location | true | 输入城市名或经纬度,城市名称如:北京,经纬度格式为lng,lat坐标如: location=116.305145,39.982368;城市天气预报中间"|"分 隔,location=116.305145,39.982368| 122.305145,36.982368|…. |
String | output | false | 输出的数据格式,默认为xml格式,当output设置为’json’时,输出的为json格式的数据; |
String | coord_type | false | 请求参数坐标类型,默认为gcj02经纬度坐标。允许的值为bd09ll、bd09mc、gcj02、wgs84。bd09ll表示百度经纬度坐标,bd09mc表示百度墨卡托坐标,gcj02表示经过国测局加密的坐标。wgs84表示gps获取的坐标。 |

2.在网页上查看数据接口的数据
XML格式的数据:
1 <?xml version="1.0" encoding="utf-8" ?> 2 <CityWeatherResponse> 3 <status>success</status> 4 <date>2014-05-03</date> 5 <results> 6 7 <currentCity>北京</currentCity> 8 <weather_data> 9 <date>周六(今天, 实时:22℃)</date> 10 <dayPictureUrl>http://api.map.baidu.com/images/weather/day/leizhenyu.png</dayPictureUrl> 11 <nightPictureUrl>http://api.map.baidu.com/images/weather/night/duoyun.png</nightPictureUrl> 12 <weather>雷阵雨转多云</weather> 13 <wind>北风5-6级</wind> 14 <temperature>24 ~ 11℃</temperature> 15 <date>周日</date> 16 <dayPictureUrl>http://api.map.baidu.com/images/weather/day/duoyun.png</dayPictureUrl> 17 <nightPictureUrl>http://api.map.baidu.com/images/weather/night/qing.png</nightPictureUrl> 18 <weather>多云转晴</weather> 19 <wind>北风4-5级</wind> 20 <temperature>19 ~ 8℃</temperature> 21 <date>周一</date> 22 <dayPictureUrl>http://api.map.baidu.com/images/weather/day/qing.png</dayPictureUrl> 23 <nightPictureUrl>http://api.map.baidu.com/images/weather/night/qing.png</nightPictureUrl> 24 <weather>晴</weather> 25 <wind>微风</wind> 26 <temperature>21 ~ 9℃</temperature> 27 <date>周二</date> 28 <dayPictureUrl>http://api.map.baidu.com/images/weather/day/duoyun.png</dayPictureUrl> 29 <nightPictureUrl>http://api.map.baidu.com/images/weather/night/qing.png</nightPictureUrl> 30 <weather>多云转晴</weather> 31 <wind>微风</wind> 32 <temperature>21 ~ 10℃</temperature> 33 </weather_data> 34 </results> 35 </CityWeatherResponse>

下面用一个demo来获取天气的数据(以获取json为例 就不解析了):
1 public class MainActivity extends Activity { 2 3 private TextView showTextView; 4 5 private AsyncHttpClient mAsyncHttpClient; 6 7 private String Url = "你的百度天气接口"; 8 9 @Override 10 protected void onCreate(Bundle savedInstanceState) { 11 super.onCreate(savedInstanceState); 12 setContentView(R.layout.activity_main); 13 14 showTextView = (TextView) findViewById(R.id.showTextView); 15 16 mAsyncHttpClient = new AsyncHttpClient(); 17 18 mAsyncHttpClient.get(Url, null, new JsonHttpResponseHandler() { 19 20 @Override 21 public void onSuccess(JSONObject result) { 22 super.onSuccess(result); 23 24 showTextView.setText(result.toString()); 25 } 26 27 @Override 28 public void onFinish() { 29 // TODO Auto-generated method stub 30 super.onFinish(); 31 } 32 33 }); 34 35 } 36 }
