最近遇到用户注册时，需要调用短信接口，发送验证码，做了个调用淘宝短信接口的例子首先需要对短信接口内容进行封装：
public class SendMsg2Util {private static String url="http://gw./router/rest";private static String appkey="xxxxxxxx";private static String secret="xxxxxxxx";public void sendMsg(String name,String phone,String vcode) throws ApiException{TaobaoClient client = new DefaultTaobaoClient(url, appkey, secret);AlibabaAliqinFcSmsNumSendRequest req = new AlibabaAliqinFcSmsNumSendRequest();req.setExtend("XXX");req.setSmsType("normal");req.setSmsFreeSignName("注册验证");req.setSmsParamString("{\"name\":\""+name+"\",\"code\":\""+vcode+"\"}");req.setRecNum(phone);req.setSmsTemplateCode("SMS_11415328");AlibabaAliqinFcSmsNumSendResponse rsp = client.execute(req);System.out.println(phone+"]验证码："+vcode+">"+rsp.getMsg());}public void sendMsg(String name,String phone) throws ApiException{TaobaoClient client = new DefaultTaobaoClient(url, appkey, secret);AlibabaAliqinFcSmsNumSendRequest req = new AlibabaAliqinFcSmsNumSendRequest();req.setExtend("XXX");req.setSmsType("normal");req.setSmsFreeSignName("变更验证");req.setSmsParamString("{\"name\":\""+name+"\",\"phone\":\""+phone+"\"}");req.setRecNum(phone);req.setSmsTemplateCode("SMS_11535513");AlibabaAliqinFcSmsNumSendResponse rsp = client.execute(req);System.out.println(rsp.getBody());}public String sendVlidMsg(String name,String phone,String vcode) throws ApiException{TaobaoClient client = new DefaultTaobaoClient(url, appkey, secret);AlibabaAliqinFcSmsNumSendRequest req = new AlibabaAliqinFcSmsNumSendRequest();req.setExtend("XXX");req.setSmsType("normal");req.setSmsFreeSignName("XXX");req.setSmsParamString("{\"name\":\""+name+"\",\"code\":\""+vcode+"\"}");req.setRecNum(phone);req.setSmsTemplateCode("SMS_52125325");AlibabaAliqinFcSmsNumSendResponse rsp = client.execute(req);if(rsp.getErrorCode()==null ||rsp.getErrorCode().equals("0")){return "0";}else{return rsp.getMsg();}}public String createRandomVcode(){//验证码String vcode = "";for (int i = 0; i < 6; i++) {vcode = vcode + (int)(Math.random() * 9);}return vcode;}}
以上是发送短信的工具类，接下来前台发送请求：
<button type="button" class="vcode-btn" id="vcode-btn">获取验证码</button>//这些是格式设置，不做参考<div class="input_row" style="display: none;" id="vcode_div"><label for="name"><span class="iconfont icon-radiobutton2 medium_size"></span></label><div class="input_row_bd"><input id="vcode" type="text" placeholder="输入验证码" /></div><div class="input_row_ft"><i class="weui-icon-warn"id="code_icon"></i></div></div>$("#vcode-btn").click(function() {$("#vcode_div").show();$.ajax({type : "post",dataType : "text",url : "getValidPhoneCode.do",data : {length : 4,phone : phone,},success : function(result) {var rsObj = typeof result === "object" ? result : $.parseJSON(result);if (rsObj.status == 0) {var step = 59;$('#vcode-btn').html('重发60');var _res = setInterval(function(){ $("#vcode-btn").attr("disabled", true);//设置disabled属性$('#vcode-btn').html('重发'+step);step-=1;if(step <= 0){$("#vcode-btn").removeAttr("disabled"); //移除disabled属性$('#vcode-btn').html('获取验证码');clearInterval(_res);//清除setInterval}},1000);}else{alert(rsObj.responseDescription);}}})})
前台发送请求后，后台对请求作出反应
@RequestMapping("/getValidPhoneCode.do")@ResponseBodypublic void getValidPhoneCode(HttpServletRequest request,HttpServletResponse response) {ResponseHeader resData = new ResponseHeader();resData.setStatus(-1);int length = requestUtil.getIntValue(request, "length");String phone = requestUtil.getStringValue(request, "phone");//此处工具类随机生成按照需要的位数生成的验证码；String phonecode = EncodeUtilTools.getRanomNumCode(length);request.getSession().setAttribute(phone, phonecode);SendMsg2Util sendmsg=new SendMsg2Util();String rs="0";//resData.setStatus(0);try {rs=sendmsg.sendVlidMsg(name, phone, phonecode);if(rs.equals("0")){resData.setStatus(0);}else{resData.setResponseDescription(rs);}} catch (ApiException e) {resData.setResponseDescription("短信接口异常，请稍后再试");}System.out.println(phone+"]验证码："+phonecode+"_"+rs);ResponseUtil.responseJson(response, resData);return;}/*** 生成随机数字* @param 编码长度* @return String*/public static String getRanomNumCode(int length) {Random random = new Random();String result = "";for (int i = 0; i < length; i++) {result += random.nextInt(10);}return result;}
以上就完成的短信的发送功能，接下来就是对验证码进行验证
$.ajax({url : DOMAIN_URL + "/wechat/getCheckSesCode.do",data : {code : vcode,key : localphone,},type : "post",dataType : "text",success : function(result) {var rsObj = typeof result === "object" ? result : $.parseJSON(result);if (rsObj.status == 0) {//此处验证码正确，给出操作}else{//验证码错误，给出相应的操作}}});
前台发出请求验证验证码是否正确，后台对其作出响应
/*** 检验手机校验的code是否正确* @param request* @param response*/@RequestMapping("/getCheckSesCode.do")@ResponseBodypublic void getCheckSesCode(HttpServletRequest request,HttpServletResponse response) {ResponseHeader resData = new ResponseHeader();resData.setStatus(-1);String key = requestUtil.getStringValue(request, "key");String code = requestUtil.getStringValue(request, "code");if(key!=null &&code!=null){String scode=(String) request.getSession().getAttribute(key);if(scode.equals(code)){resData.setStatus(0);}}ResponseUtil.responseJson(response, resData);return;}/*** 获得String类型请求参数* * @param request* @param name* @return*/public String getStringValue(HttpServletRequest request, String name) {return StringUtil.isEmpty(name) ? null : request.getParameter(name);}
通过以上步骤，就完成了发送验证码以及对验证码进行验证的功能
