HTML代碼就不寫了，JS如下：vailidationCode是獲取驗(yàn)證碼按鈕的ID。phone是手機(jī)號(hào)碼的ID，手機(jī)號(hào)碼只是簡(jiǎn)單的驗(yàn)證了，如果是要更精確，使用正則，其中的url的sendSms是后臺(tái)的springMVC的路徑。

$("#validationCode").click(function(){
var phone = $("#phone").val();
if($("#phone").val() && $("#phone").val().length == 11){
$.ajax({
cache : false,
url : "sendSms",
data : {phone : phone}
});
updateButtonStatus();
}else {
alert("請(qǐng)輸入合法的手機(jī)號(hào)");
}
});
var countdown=60;
function updateButtonStatus(){
var phone = $("#validationCode");
if (countdown == 0) {
phone.attr("disabled","false");
phone.val("免費(fèi)獲取驗(yàn)證碼");
countdown = 60;
return;
} else {
phone.attr("disabled","true");
phone.val("重新發(fā)送(" + countdown + ")");
countdown--;
}
setTimeout(function() {
updateButtonStatus() }
,1000)
}

后端代碼

@RequestMapping(value = "/sendSms")
@ResponseBody
public String sendSMS(@RequestParam("phone") String phone, HttpServletRequest request){
StringBuilder code = new StringBuilder();
Random random = new Random();
// 生成6位驗(yàn)證碼
for (int i = 0; i < 6; i++) {
code.append(String.valueOf(random.nextInt(10)));
}
HttpSession session = request.getSession();
session.setAttribute(VALIDATE_PHONE, phone);
session.setAttribute(VALIDATE_PHONE_CODE, code.toString());
session.setAttribute(SEND_CODE_TIME, new Date().getTime());
String smsText = "您的驗(yàn)證碼是:"+code;
SMSUtil.send(phone,smsText);
return "success";
}

其中的SMSUtil是封裝的上面的短信接口的發(fā)送類。參考如下，其中的API_KEY改成自己的。

public class SMSUtil {
static String httpUrl = "http://apis.baidu.com/kingtto_media/106sms/106sms";
final static String API_KEY = "xxxx";
public static String send(String phone,String content) {
BufferedReader reader = null;
String result = null;
StringBuffer sbf = new StringBuffer();
try {
String httpArg = "mobile="+phone+"&content="+URLEncoder.encode(content,"UTF-8")+"&tag=2";
httpUrl = httpUrl + "?" + httpArg ;
URL url = new URL(httpUrl);
HttpURLConnection connection = (HttpURLConnection) url
.openConnection();
connection.setRequestMethod("GET");
// 填入apikey到HTTP header
connection.setRequestProperty("apikey",API_KEY);
connection.connect();
InputStream is = connection.getInputStream();
reader = new BufferedReader(new InputStreamReader(is, "UTF-8"));
String strRead = null;
while ((strRead = reader.readLine()) != null) {
sbf.append(strRead);
sbf.append("\r\n");
}
reader.close();
result = sbf.toString();
} catch (Exception e) {
e.printStackTrace();
}
return result;
}
}

前臺(tái)的表單提交前還需要使用ajax做一下表單的驗(yàn)證，驗(yàn)證一下驗(yàn)證碼是否正確：

@RequestMapping("/validate")
@ResponseBody
protected String validate(HttpServletRequest request,@RequestParam("phone") String inputPhone,@RequestParam ("code") String inputCode){
HttpSession session = request.getSession();
String code = (String) session.getAttribute(VALIDATE_PHONE_CODE);
String phone = (String) session.getAttribute(VALIDATE_PHONE);
if(phone.equals(inputPhone) && code.equalsIgnoreCase(inputCode)){
return "success";
}else{
return "failure";
}
}
