google 天气预报API

http://www.cnblogs.com/ylligang/articles/2304434.html

Google Weather API 只支持美国地区使用邮政编码进行查询,例如:
http://www.google.com/ig/api?hl=zh-cn&weather=94043
(94043 为 山景城, 美国加州 的邮政编码)
而除了美国以外的地区需要使用经纬度坐标作为参数才能执行 Google Weather API, 例如:
http://www.google.com/ig/api?hl=zh-cn&weather=,,,30670000,104019996
(30670000,104019996 为 成都, 中国大陆 的经纬度坐标)

当然,也可能通行城市名称的汉语拼音来查询,例如:以下是北京的天气

http://www.google.com/ig/api?weather=Beijing

要其它地区的经纬度坐标,可以通过 Google API 提供的国家代码列表及相应的城市经纬度坐标列表可以查询到,以下是 Google API 提供的查询参数:
http://www.google.com/ig/countries?output=xml&hl=zh-cn
(查询 Google 所支持的所有国家的代码,并以 zh-cn 简体中文显示)
http://www.google.com/ig/cities?output=xml&hl=zh-cn&country=cn

Google开放了一套天气预报API，还是很好用的。

使用邮政编码(美国)
http://www.google.com/ig/api?hl=zh-cn&weather=94043(加州山景城)

使用经度纬度坐标
http://www.google.com/ig/api?hl=zh-cn&weather=,,,30670000,104019996(成都)

使用通行城市名称
http://www.google.com/ig/api?weather=Beijing&hl=zh-cn(北京)
http://www.google.com/ig/api?weather=Osaka&hl=zh-cn(大阪)
或
http://www.google.com/ig/api?weather=Beijing&hl=zh(北京)
http://www.google.com/ig/api?weather=Osaka&hl=ja(大阪)

可以查找到哪些国家和城市呢？谷歌也提供了接口。返回的类型也可以根据output参数来指定。
查找国家  http://www.google.com/ig/countries?output=xml&hl=zh-cn (返回xml)
查找城市  http://www.google.com/ig/cities?hl=zh-cn&country=cn (返回json)

有了这些数据，在自己的应用里加入天气预报就不难了。

android 通过Google Weather Api 获取天气预报

 

获取天气的链接地址

根据经纬度获取：http://www.google.com/ig/api?weather=,,,31174165,121433841

【如中山的经纬度是：22.516997123628076,113.39263916015625 必须都乘以1000000才能作为参数】

int a=(int)22.516997123628076*1000000;int b=(int)113.39263916015625*1000000;String strUrl ="http://www.google.com/ig/api?hl=zh-cn&weather=,,,"+a+","+b;System.out.println(strUrl);

复制代码

根据地名获取：http://www.google.com/ig/api?hl=zh-cn&weather=Beijing

                        String strData ="";                        String strUrl ="http://www.google.com/ig/api?hl=zh-cn&weather=ZhongShan";                        strData = getResponse(strUrl);                                                // 天气预报的xml存储在sd卡中new FileUnit().write(strData, "weather.xml");                        // SAX解析xmltry {                            SAXParserFactory spf = SAXParserFactory.newInstance();                            SAXParser sp = spf.newSAXParser();                            SAXReader saxReader =new SAXReader();                                                        InputSource is =new InputSource();                            is.setByteStream(new ByteArrayInputStream(strData.getBytes()));                            sp.parse(is, saxReader);                                                        weatherList=saxReader.getWeathList();                                                    } catch (Exception e) {                            e.printStackTrace();                        }                                                                        //显示天气预报                        showWeather();

复制代码

根据地址 获得xml的String

   protected String getResponse(String queryURL) {        URL url;        try {            url =new URL(queryURL.replace("", "%20"));            URLConnection urlconn = url.openConnection();            urlconn.connect();            InputStream is = urlconn.getInputStream();            BufferedInputStream bis =new BufferedInputStream(is);            ByteArrayBuffer buf =new ByteArrayBuffer(50);            int read_data =-1;            while ((read_data = bis.read()) !=-1) {                buf.append(read_data);            }            // String resp = buf.toString();            String resp = EncodingUtils.getString(buf.toByteArray(), "GBK");            return resp;        } catch (MalformedURLException e) {            // TODO Auto-generated catch block            e.printStackTrace();            return"";        } catch (IOException e) {            // TODO Auto-generated catch block            e.printStackTrace();            return"";        }    }
