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apikey
、mobile
和text
。
php发起http/https请求
使用php的curl函数发起https请求,带入参数apikey
、mobile
和text
。
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41
| public function getSMSCode(){
$ch = curl_init();
$url = 'https://sms.yunpian.com/v1/sms/send.json'; curl_setopt($ch, CURLOPT_URL, $url);
$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($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$output = curl_exec($ch);
curl_close($ch);
echo $output; }
|
生成随机短信验证码
默认生成四位的随机短信验证码。
1 2 3 4 5 6
| public function createSMSCode($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;
|
thinkphp代码:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79
| public function getSMSCode(){
$ch = curl_init();
$url = 'https://sms.yunpian.com/v1/sms/send.json'; curl_setopt($ch, CURLOPT_URL, $url);
$mobile = $_POST['mobile']; $code = $this->createSMSCode(); $paramArr = array( 'apikey' => '******', 'mobile' => $mobile, 'text' => '【小太阳】您的验证码是'.$code ); $param = ''; foreach ($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($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$output = curl_exec($ch);
curl_close($ch); $outputArr = json_decode($output, true);
if($outputArr['code'] == '0'){ $data['mobile'] = $mobile; $data['code'] = $code;
$smscode = D('smscode'); $smscodeObj = $smscode->where("mobile='$mobile'")->find(); if($smscodeObj){ $data['update_at'] = date('Y-m-d H:i:s'); $success = $smscode->where("mobile='$mobile'")->save($data); if($success !== false){ $result = array( 'code' => '0', 'ext' => '修改成功', 'obj' => $smscodeObj ); } echo json_encode($result,JSON_UNESCAPED_UNICODE); }else{ $data['create_at'] = date('Y-m-d H:i:s'); $data['update_at'] = $data['create_at']; if($smscode->create($data)){ $id = $smscode->add(); if($id){ $smscode_temp = $smscode->where("id='$id'")->find(); $result = array( 'code'=> '0', 'ext'=> '创建成功', 'obj'=>$smscode_temp ); 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。
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51
| public function checkSMSCode(){ $mobile = $_POST['mobile']; $code = $_POST['code']; $nowTimeStr = date('Y-m-d H:i:s');
$smscode = D('smscode'); $smscodeObj = $smscode->where("mobile='$mobile'")->find(); if($smscodeObj){ $smsCodeTimeStr = $smscodeObj['update_at']; $recordCode = $smscodeObj['code']; $flag = $this->checkTime($nowTimeStr, $smsCodeTimeStr); if(!$flag){ $result = array( 'code' => '1', 'ext' => '验证码过期,请刷新后重新获取' ); echo json_encode($result,JSON_UNESCAPED_UNICODE); return; }
if($code != $recordCode){ $result = array( 'code' => '2', 'ext' => '验证码错误,请重新输入' ); echo json_encode($result,JSON_UNESCAPED_UNICODE); return; }
$result = array( 'code' => '0', 'ext' => '验证通过' ); echo json_encode($result,JSON_UNESCAPED_UNICODE); } }
public function checkTime($nowTimeStr,$smsCodeTimeStr){ $nowTime = strtotime($nowTimeStr); $smsCodeTime = strtotime($smsCodeTimeStr); $period = floor(($nowTime-$smsCodeTime)/60); if($period>=0 && $period<=20){ return true; }else{ return false; } }

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
1 2 3 4 5 6 7 8 9 10 11
| public function getPicCode(){ $config = array( 'fontSize'=>30, 'length'=>4, 'useNoise'=>false, 'expire'=>600 ); $Verify = new \Think\Verify($config); $Verify->entry(2333); }
|
假设,该函数的对应url为http://localhost/owner-bd/index.php/Home/CheckCode/getPicCode
,那么,图片验证码的地址就是这个url,放入页面图片标签的src属性即可。
验证图片验证码
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17
| public function checkPicCode($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 2 3 4 5 6 7 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。
1 2 3 4 5 6 7 8 9 10 11 12 13
| public function getSMSCode(){ $picCode = $_POST['picCode']; if(!$this->checkPicCode($picCode)){ $result = array( 'code' => '1', 'ext' => '验证码错误,请重新输入' ); echo json_encode($result,JSON_UNESCAPED_UNICODE); return; } }
|

$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); echo session_id();
|
