JAVA：獲得網頁下載文件內容

 

//urlString爲文件的下載路徑，如http://abc.com/asd.mp3

 

public static String getBuffer(String urlString) throws Exception {
        StringBuffer sb = new StringBuffer();  //存放下載的文件序列 
        String line = null; 
        BufferedReader buffer = null; 
         
               // 創建一個URL對象 
        URL url = new URL(urlString); 
               // 創建一個Http連接 
        HttpURLConnection urlConn = (HttpURLConnection) url.openConnection(); 
        // 使用IO流讀取數據 
        buffer = new BufferedReader(new InputStreamReader(urlConn.getInputStream())); 
            while ((line = buffer.readLine()) != null) { 
                    sb.append(line); 
                    sb.append("\n");
                    } 
        buffer.close(); 
        return sb.toString();
    }
