得到一个给定url的内容

因为论坛上好多人问这个问题，我会，呵呵，就发给大家看一下！  

public static String getHtml(String tempurl,String code){    

try{   URL url = new URL(tempurl);    

HttpURLConnection conn = (HttpURLConnection)url.openConnection();    

conn.connect();   

 InputStream is = conn.getInputStream();    

BufferedReader br = new BufferedReader(new InputStreamReader(is,code));    String line="";   

StringBuffer resultBuffer = new StringBuffer();   

while((line = br.readLine())!=null){     

resultBuffer.append(line);    

}    

br.close();    

is.close();    

conn.disconnect();   

return resultBuffer.toString();  

}  

catch(Exception e){}  

return null; 

}

其中，tempurl为指定的url地址，

code是指定url页面的页面编码
