JAVA实现手机短信验证码

手机短信验证码接口来自于网易云手机短信接口

       for (int j = 0; j < len; j++) {
           buf.append(HEX_DIGITS[(bytes[j] >> 4) & 0x0f]);
           buf.append(HEX_DIGITS[bytes[j] & 0x0f]);

           '6', '7', '8', '9', 'a', 'b', 'c', 'd', 'e', 'f' };
}

以下代码为截取main方法中输入的字符串（只获取到有效的短信验证码）

String line=EntityUtils.toString(response.getEntity(), "utf-8");
	        Integer dex=line.lastIndexOf(':');
	        String str=line.substring(dex+2,dex+8 );
	        //System.out.println("8888:"+str);
			return (str);
