天气代码高级使用方法:
如果您会HTML语言,您还可以在iframe代码中的url后面加参数,如:
chengshi_321.html?c0=F9DC68&c1=white&c2=FEFCE0&t1=red&bg=white&w=178&h=250&text=no
其中 c0 表示 表格第一行背景颜色,c1,c2表示表格其他行间隔的背景颜色,t1表示 标题颜色,bg 表示页面北京颜色,w表示表格宽度 h 表示表格高度
当 text=yes 时,将会出现滚动的天气文字,建议您自己调试看看,如:
chengshi_321.html??c0=red&c1=FF9900&bg=F4FFF4&w=178&h=20&text=yes
注意:颜色请不要加 # 符号,如 #FF9900 请写成 FF9900 |

http://minisite.qq.com/Weather/news_new.h tml" allowTransparency="true"></iframe>
效果:
说明:这种适合于在网页的边栏插入。但一个缺点是,上面的4个城市是既定的,无法改成别的。插 入时,选好网页上的位置,直接将左栏的源代码全部拷进去就行了

效果:
说明:这种也适合于在网页的边栏插入。上面的城市可以自定,比如厦门可改成别的。定制的方法是修改我代码中标红的数字,从1开始代表“香港”开始,每个数字都代表一个城市,厦门是287,具体要哪个城市自己找一下罢。

自己从网页中偷取天气数据
主要用到Pattern类和Matcher类在java.util.regex.包下面。
首先在网页上取得所有数据
HttpURLConnection conn = null;
String outstr = "";
try {
String strUrl = "http://www.wopos.com/MainSet/WeatherSet.aspx?city="+address;
URL url = new URL(strUrl);
conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("GET");
BufferedReader br = new BufferedReader(new InputStreamReader(conn.
getInputStream(), "GBK"));
String line = "";
while ((line = br.readLine()) != null) {
outstr = outstr + line;
}
br.close();
} catch (Exception ex) {
ex.printStackTrace(System.out);
} finally {
if (conn != null) {
conn.disconnect();
}
}
然后分析数据
try{
Pattern p = Pattern.compile("<span id=\"Label\\d\" style=\"display:inline-block;\"><font size=\"\\d\">[\u4e00-\u9fa5]*\\d*[℃]*[~]*[.]*[-]*\\d*[℃]*[-]*\\d*[.]*\\d*[:]*[\u4e00-\u9fa5]*</font></span>");
Matcher m = p.matcher(outstr);
while (m.find()) {
String s = m.group();
// System.out.println("s=" + s);
if(s!=null){
hm.put(s.substring(10, 16), s);
}
}
}catch(Exception ex){
ex.printStackTrace(System.out);
}
完整的例子为
public class WoWeatherInit {
Weather weather = new Weather();
SimpleDateFormat df=new SimpleDateFormat("yyyy-MM-dd");
String time=df.format(date);
public void getWeatherInit() {
//开始分析返回的xml
HttpURLConnection conn = null;
String outstr = "";
String outstrtest = "";
ObjectInputStream input = null;
HashMap hm = new HashMap();
HashMap hm1 = new HashMap();
try {
String strUrl = "http://www.wopos.com/MainSet/WeatherSet.aspx?city="+address;
URL url = new URL(strUrl);
conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("GET");
BufferedReader br = new BufferedReader(new InputStreamReader(conn.
getInputStream(), "GBK"));
String line = "";
while ((line = br.readLine()) != null) {
outstr = outstr + line;
}
br.close();
} catch (Exception ex) {
ex.printStackTrace(System.out);
} finally {
if (conn != null) {
conn.disconnect();
}
}
if(outstr == null){
System.out.println("null");
}
try{
Pattern p = Pattern.compile("<span id=\"Label\\d\" style=\"display:inline-block;\"><font size=\"\\d\">[\u4e00-\u9fa5]*\\d*[℃]*[~]*[.]*[-]*\\d*[℃]*[-]*\\d*[.]*\\d*[:]*[\u4e00-\u9fa5]*</font></span>");
Matcher m = p.matcher(outstr);
while (m.find()) {
String s = m.group();
// System.out.println("s=" + s);
if(s!=null){
hm.put(s.substring(10, 16), s);
}
}
}catch(Exception ex){
ex.printStackTrace(System.out);
}
String sAddress = getAddress(hm);
String sDate = getDate(hm);
String sTianQi = getTianQi(hm);
String sWenDu = getWenDu(hm);
String sWind = getWind(hm);
}
//获取地址
public String getAddress(HashMap hm){
String sValue = "";
try {
String sText = (String)hm.get("Label5");
String sFont = "<font size=\"2\">";
int iBegin = sText.indexOf(sFont);
int iEnd = sText.indexOf("</font>");
sValue = sText.substring(iBegin+sFont.length(), iEnd);
} catch (Exception ex) {
ex.printStackTrace(System.out);
sValue="";
} finally{
return sValue;
}
}
//获取天气
public String getTianQi(HashMap hm){
String sValue = "";
try {
String sText = (String)hm.get("Label1");
String sFont = "<font size=\"2\">";
int iBegin = sText.indexOf(sFont);
int iEnd = sText.indexOf("</font>");
sValue = sText.substring(iBegin+sFont.length(), iEnd);
} catch (Exception ex) {
ex.printStackTrace(System.out);
sValue="";
} finally{
return sValue;
}
}
// 获取日期
public String getDate(HashMap hm){
String sValue = "";
try {
String sText = (String)hm.get("Label7");
String sFont = "<font size=\"2\">";
int iBegin = sText.indexOf(sFont);
int iEnd = sText.indexOf("</font>");
sValue = sText.substring(iBegin+sFont.length(), iEnd);
} catch (Exception ex) {
ex.printStackTrace(System.out);
sValue="";
} finally{
return sValue;
}
}
//获取温度
public String getWenDu(HashMap hm){
String sValue = "";
try {
String sText = (String)hm.get("Label2");
String sFont = "<font size=\"2\">";
int iBegin = sText.indexOf(sFont);
int iEnd = sText.indexOf("</font>");
sValue = sText.substring(iBegin+sFont.length(), iEnd);
} catch (Exception ex) {
ex.printStackTrace(System.out);
sValue="";
} finally{
return sValue;
}
}
// 获取风力
public static String getWind(HashMap hm){
String sValue = "";
try {
String sText = (String)hm.get("Label3");
String sFont = "<font size=\"2\">";
int iBegin = sText.indexOf("<font size=\"2\">");
int iEnd = sText.indexOf("</font>");
sValue = sText.substring(iBegin+sFont.length(), iEnd);
} catch (Exception ex) {
ex.printStackTrace(System.out);
}
return sValue;
}
}
