获取验证码

		        </div>
      
                       <button type="submit" id="submit" tabindex="4">登 录</button>
<script type="text/javascript">
    //点击获取验证码按钮
        $(\'.action-get-verifycode\').click(function(e){
		e.preventDefault();
        var el = document.getElementById(\'username\') ;
        var elp = document.getElementById(\'password\') ;
        if(this.hasClass(\'disabled\')) return false;
        sendVerify(this,\'username\' + \'=\' + el.value + \'&password\' + \'=\' + elp.value);
});

	function sendVerify(el,data) {
    var url = el.href;
    var textCont = el.getElement(\'span span\');
	el.addClass(\'disabled\');
 	// $(el).find(\'span\').attr(\'disabled\',true);
 	// $(el).attr(\'disabled\',true);
    textCont.innerHTML = el.innerText + \'(<i>0</i> )\';
    var ttt = textCont.getElement(\'i\');
    var cd = new countdown(textCont.getElement(\'i\'), {
        start: 60,
        secondOnly: true,
        callback: function(e) {
            el.removeClass(\'disabled\');
            textCont.innerHTML = \'重发验证码\';
        }
    });
    Query.send(url, el, data, function(rs) {
        if(rs.success) {
            cd.stop();
            el.removeClass(\'disabled\');
            textCont.innerHTML = \'重发验证码\';
        }else{
            cd.stop();
        	el.removeClass(\'disabled\');
            textCont.innerHTML = \'获取验证码\';
        }
    });
}

5.验证用户名，密码，短信发送次数等，然后 调用方法：

//随机取6位字符数
public function randomkeys($length){
$key = \’\’;
$pattern = \’1234567890\’; //字符池
for($i=0;$i<$length;$i++){
$key .= $pattern{mt_rand(0,9)}; //生成php随机数
}
return $key;
}

//设置session保存时间

public function start_session($expire = 0) {
if ($expire == 0) {
$expire = ini_get(\’session.gc_maxlifetime\’);
} else{
ini_set(\’session.gc_maxlifetime\’, $expire);
}
session_start();
setcookie(session_name(), session_id(), time() + $expire, “/”);
}

从前台传入用户名和密码，判断是否正确
function actionSetVcode(){

	//判断是否填写用户名
	if($_POST[\'username\']){
		$p[\'username\']=$_POST[\'username\'];
	}else{
		$msg = "无效用户名!";
		echo json_encode(array(\'success\'=>false,\'msg\'=>$msg));
		exit;
	}

	$m=FLEA::getSingleton(\'Model_Acm_User\');//加载用户的数据库

	//判断用户名和密码是否一致
	$str = " SELECT passwd from acm_userdb where userName=\'{$p[\'username\']}\'";
	$passwd = $m->findBySql($str);

	if($passwd[0][\'passwd\']!=$_POST[\'password\']){
		$msg = "用户名和密码不一致!";
		echo json_encode(array(\'success\'=>false,\'msg\'=>$msg));
		exit;
	}

	//判断用户是否绑定手机号
	$sql = "SELECT phone from acm_userdb where userName=\'{$p[\'username\']}\'";
	$rs = $m->findBySql($sql);

	if(!$rs[0][\'phone\'] && $p[\'username\']!=\'admin\'){
		$msg = "对应用户可能没绑定手机号!";
		echo json_encode(array(\'success\'=>false,\'msg\'=>$msg));
		exit;
	}

	$_SESSION[\'count\'] = isset($_SESSION[\'count\'])?$_SESSION[\'count\']:0;
	if($_SESSION[\'count\']>=3){
		$msg = "今日发送次数已用完";
		echo json_encode(array(\'success\'=>false,\'msg\'=>$msg));
		exit;
	}

    if( time() - $_SESSION[\'lastmodify\'] < 120 ){
                $msg = \'2分钟发送一次,还没到两分钟则不进行发送\';
                echo json_encode(array(\'success\'=>false,\'msg\'=>$msg));
	    exit;
        }




    $vcode = $this->randomkeys(6);//取得随机6位数验证码

    $mobile = $rs[0][\'phone\'];
    $time_sess = 3600 * 3;//设置验证码有效时间
	$this->start_session($time_sess);

    $_SESSION[\'VcodeforLogin\'] = $vcode;
    $_SESSION[\'mobileforLogin\'] = $mobile;
    $_SESSION[\'username\'] = $_POST[\'username\'];
    $_SESSION[\'password\'] = $_POST[\'password\'];
    $_SESSION[\'count\'] ++;
    $_SESSION[\'lastmodify\'] = time();

    $content = "您的验证码是：".$vcode."。请不要把验证码泄露给其他人。";

$Sms = FLEA::getSingleton(\'Controller_Org_Sms\');//加载api控制器接口
$result = $Sms->sendSms(array(\'to\'=>$mobile ,\'content\'=>$content));//调用sendSms方法，$mobile是发送给谁，$content是发送的内容，

    $result =  json_decode($result,1);

    $arr = array(\'success\'=>true);
	echo json_encode($arr);exit;//
}

6.点击登录，传用户名，密码，填写的验证码和发送的验证码是否一致；
//确定按钮点击后效果
$(\’#form_login\’).submit(function(){

		var verify = $(\'#verify\').val();
		var username = $(\'#username\').val();
		var password = $(\'#password\').val()；


			//填写验证码
		var url = "?controller=Login&action=loginIndex";
		var param = {
				\'username\':username,
				\'password\':password,
				\'verify\':verify
		};
		$(\'#submit\').attr(\'disabled\',true);
		$.ajax({
	            type: "POST",
	            url: url,
	            data: param,
	            dataType: \'json\',
	            async: false,//同步操作
	            success:function(json){
	            	console.log(json);
		            if(json.success==false){
		                showError(json.msg);
		                setTimeout(function(){
							$(\'#submit\').attr(\'disabled\',false);
							$(\'#submit\').text(\'登 录\');

						}, 500);
		        		return false;

		            }else{
		                showMsg(\'登陆成功\');
		            }
	           },

	        });
	        var urls = "?controller=Main&action=Index";
		setTimeout(function(){window.location.href=urls;}, 500);

	        return false;

		$(\'#submit\').attr(\'disabled\',true);
		$(\'#submit\').text(\'登录中…\');
		$(this).ajaxSubmit({
			\'data\':{\'is_ajax\':true},
			success:function(t,b,f){
				var json = eval("("+t+")");
				if(json.success==true){
					showMsg(\'登陆成功\');
					setTimeout(function(){window.location.href=json.href;}, 500);
				}else{
					showError(json.msg);
					setTimeout(function(){
						$(\'#submit\').attr(\'disabled\',false);
						$(\'#submit\').text(\'登 录\');
					}, 500);
				}
			}
		});
		
		return false;
	});
