thinkphp实现短信验证注册

前言

小太阳项目最先做的模块,用户管理模块。业主端该模块分为三个功能:注册登录、个人信息修改、认证。
注册时需要用到短信验证码,本文记录一下思路和具体实现。
短信验证平台使用云片,短信验证码的生成使用thinkphp。

思路

1、用户输入手机号,请求获取短信验证码。
2、thinkphp生成短信验证码,存储,同时和其他参数一起发送请求给云片。
3、云片发送短信验证码到指定手机号。
4、用户输入短信验证码。
5、thinkphp根据验证码是否正确、验证码是否过期两个条件判断是否验证通过。

代码实现

验证接口

接口地址:https://sms.yunpian.com/v1/sms/send.json
使用postman,输入三个必须的参数apikeymobiletext

php发起http/https请求

使用php的curl函数发起https请求,带入参数apikeymobiletext

// 获取短信验证码
public function getSMSCode(){

// create curl resource
$ch = curl_init();

// set url
$url = 'https://sms.yunpian.com/v1/sms/send.json';
curl_setopt($ch, CURLOPT_URL, $url);

// set param
$paramArr = array(
'apikey' => '******',
'mobile' => '******',
'text' => '【小太阳】您的验证码是1234'
);
$param = '';
foreach ($paramArr as $key => $value) {
$param .= urlencode($key).'='.urlencode($value).'&';
}
$param = substr($param, 0, strlen($param)-1);

curl_setopt($ch, CURLOPT_POSTFIELDS, $param);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_POST, 1);

//curl默认不支持https协议,设置不验证协议
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);

//return the transfer as a string
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

// $output contains the output string
$output = curl_exec($ch);

// close curl resource to free up system resources
curl_close($ch);

echo $output;
}

生成随机短信验证码

默认生成四位的随机短信验证码。

1
2
3
4
5
6
// 生成短信验证码
public function createSMSCode($length = 4){
$min = pow(10 , ($length - 1));
$max = pow(10, $length) - 1;
return rand($min, $max);
}

整合

在数据库新建表sun_smscode:

1
2
3
4
5
6
7
8
9
DROP TABLE IF EXISTS `sun_smscode`;
CREATE TABLE `sun_smscode` (
`id` int(8) NOT NULL AUTO_INCREMENT,
`mobile` varchar(11) NOT NULL,
`code` int(4) NOT NULL,
`create_at` datetime NOT NULL,
`update_at` datetime NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM AUTO_INCREMENT=3 DEFAULT CHARSET=utf8;

echo json_encode($result,JSON_UNESCAPED_UNICODE);

}
}

验证短信验证码

验证短信验证码时间是否过期,验证短信验证码是否正确。

$period = floor(($nowTime-$smsCodeTime)/60); //60s

}else{

}
}

改进

为了防止短信轰炸,在请求获取短信验证码时,需要加入图片验证码。

thinkphp提供了生成图片验证码的函数,下面我们来实现验证码的生成、刷新和验证。

生成和刷新图片验证码

11
// 获取图片验证码,刷新图片验证码
public function getPicCode(){
$config = array(
'fontSize'=>30, // 验证码字体大小
'length'=>4, // 验证码位数
'useNoise'=>false, // 关闭验证码杂点
'expire'=>600
);
$Verify = new \Think\Verify($config);
$Verify->entry(2333);//2333是验证码标志
}

假设,该函数的对应url为http://localhost/owner-bd/index.php/Home/CheckCode/getPicCode,那么,图片验证码的地址就是这个url,放入页面图片标签的src属性即可。

验证图片验证码

// 验证验证码是否正确
public function checkPicCode($code){
$verify = new \Think\Verify();
if($verify->check($code, 2333)){
$result = array(
'code' => '0',
'ext' => '验证通过'
);
echo json_encode($result,JSON_UNESCAPED_UNICODE);
}else{
$result = array(
'code' => '1',
'ext' => '验证码错误,请重新输入'
);
echo json_encode($result,JSON_UNESCAPED_UNICODE);
};
}

以上方法,我们利用了thinkphp提供的check方法,实现起来很简单。但是,如果想要得到验证细节,就没有办法了。比如,验证码错误,可能验证码超时,可能因为输入验证码错误,可能因为验证码已经使用过等等。必要的时候,可以重写thinkphp的验证码类,或者重写thinkphp的check方法。

跑通前后端

后端修改

验证图片验证码函数,改为被调用函数:

1

3
4
5
6

8
public function checkPicCode($picCode){
$verify = new \Think\Verify();
if($verify->check($picCode, 2333)){
return true;
}else{
return false;
};
}

在获取短信验证码函数的最顶部,添加调用图片验证码函数,只有通过验证,才发送请求给云片。

$result = array(
'code' => '1',
'ext' => '验证码错误,请重新输入'
);
echo json_encode($result,JSON_UNESCAPED_UNICODE);
return;
}
/*省略*/
}

});
}

// 刷新图片验证码
$scope.refresh = function(){
$scope.picCodeUrl = '/owner-bd/index.php/Home/CheckCode/getPicCode?'+Math.random();
}

});

优化

以上代码,安全性不是很好,我们可以利用工具绕过前端验证。为了避免这个问题,可以在checkPicCode和checkSMSCode函数中添加session值来标记。

1
2
$_SESSION['checkPicCode'] = true;
$_SESSION['checkSMSCode'] = true;

在最后一步,向数据库中添加用户时,先验证一下两个session值是否都为true,都为true时再添加。

成果

后记

以后也许有用的代码:

1
2
echo json_encode($_SESSION);// 打印出session中的数据
echo session_id();// 打印当前session的id
