Thinkphp implements SMS verification registration function_php example

Foreword

SMS verification codes are often required when registering. This article records the ideas and specific implementation.

The SMS verification platform uses Yunpian, and the SMS verification code is generated using thinkphp.

Thoughts

1. The user enters the mobile phone number and requests to obtain the SMS verification code.

2. thinkphp generates the SMS verification code, stores it, and sends the request to Yunpian together with other parameters.

3. Yunpian sends a text message verification code to the designated mobile phone number.

4. The user enters the SMS verification code.

5. thinkphp determines whether the verification is passed based on two conditions: whether the verification code is correct and whether the verification code has expired.

Code implementation

Verification interface

Interface address: https://sms.yunpian.com/v1/sms/send.json.

Use postman and enter the three necessary parameters apikey, mobile and text.

php initiates http/https request

Use PHP's curl function to initiate an https request and bring in the parameters apikey, mobile and text.

// 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;
}

Generate random SMS verification code

A four-digit random SMS verification code is generated by default.

// 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);
}

Integration

Create a new table sun_smscode in the database:

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：
// 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
$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); //不验证证书下同
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($ch); 
//$outputJson = json_decode($output);
$outputArr = json_decode($output, true);
//echo $outputJson->code;
//echo $outputArr['code'];
if($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);
}
}
}
}
}

Verification SMS verification code

Verify whether the SMS verification code has expired and whether the SMS verification code is correct.

// 验证短信验证码是否有效
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);
}
}
// 验证验证码时间是否过期
public function checkTime($nowTimeStr,$smsCodeTimeStr){
//$nowTimeStr = '2016-10-15 14:39:59';
//$smsCodeTimeStr = '2016-10-15 14:30:00';
$nowTime = strtotime($nowTimeStr);
$smsCodeTime = strtotime($smsCodeTimeStr);
$period = floor(($nowTime-$smsCodeTime)/60); //60s
if($period>=0 && $period<=20){
return true;
}else{
return false;
}
}

Improvements

In order to prevent SMS bombing, when requesting to obtain the SMS verification code, you need to add the image verification code.

thinkphp provides a function to generate image verification codes. Let’s implement the generation, refresh and verification of verification codes.

Generate and refresh image verification codes

// 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
}

Assume that the corresponding url of this function is http://localhost/owner-bd/index.php/Home/CheckCode/getPicCode. Then, the address of the image verification code is this url. Just put it in the src attribute of the page image tag. .

Verification picture verification code

// 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);
};
}

For the above method, we used the check method provided by thinkphp, which is very simple to implement. However, if you want to get verification details, there is no way. For example, if the verification code is wrong, the verification code may have timed out, the verification code may have been entered incorrectly, the verification code may have been used, etc. When necessary, you can rewrite thinkphp's verification code class, or rewrite thinkphp's check method.

Complete front-end and back-end

Backend modification

Verify the image verification code function, changed to the called function:

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

At the top of the function to get the SMS verification code, add the function to call the image verification code. Only after passing the verification will the request be sent to Yunpian.

// 获取短信验证码
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;
}
/*省略*/
}

$scope.refresh = function(){

}
});

Optimization

The security of the above code is not very good. We can use tools to bypass front-end verification. In order to avoid this problem, you can add session value to mark in the checkPicCode and checkSMSCode functions.

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

In the last step, when adding a user to the database, first verify whether both session values ​​are true, and then add them when both are true.

Achievements

Postscript

Code that may be useful in the future:

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

The above is the Thinkphp implementation of SMS verification registration introduced by the editor. I hope it will be helpful to you.
