Usually when registering with a mobile phone number, you need to send a SMS verification code, and you also need to verify your mobile phone when changing passwords and other sensitive operations. Send SMS verification code. To send SMS messages in the project code, you usually need to call the SMS sending interface of the third-party SMS provider.

You can put the interface address and appkey in the configuration file. Encapsulate a function sendmsg for sending text messages. You can use the curl request method in PHP (curl function library in PHP) to send the request.

if (!function_exists('sendmsg')) {
    function sendmsg($phone, $msg){
        //从配置文件读取接口信息
        $gateway = config('msg.gateway');
        $appkey = config('msg.appkey');
        //准备请求地址
        $url = $gateway . "?appkey=" . $appkey . "&mobile=" . $phone . "&content=" . $msg;
        //发送请求 比如get方式  https请求
        $res = curl_request($url, false, [], true);
 
        if (!$res) {
            return "请求发送失败";
        }
        //请求发送成功，返回值json格式字符串
        $arr = json_decode($res, true);
        if ($arr['code'] == 10000) {
            return true;
        }
        return $arr['msg'];
    }
}

Define a sendcode method in the controller. When the front desk clicks to send the verification code, it sends an ajax request. This method receives the mobile phone number of the registered user at the front desk and calls the sendmsg function to implement the verification code SMS sending function.

 //ajax请求发送注册验证码
    public function sendcode($phone)
    {
        //参数验证
        if (empty($phone)) {
            return ['code' => 10002, 'msg' => '参数错误'];
        }
        //短信内容  您用于注册的验证码为：****，如非本人操作，请忽略。
        $code = mt_rand(1000, 9999);
        $msg = "您用于注册的验证码为：{$code}，如非本人操作，请忽略。";
        //发送短信
        $res = sendmsg($phone, $msg);
        if ($res === true) {
            //发送成功，存储验证码到session 用于后续验证码的校验
            session('register_code_' . $phone, $code);
            return ['code' => 10000, 'msg' => '发送成功', 'data' => $code];
        }
        return ['code' => 10001, 'msg' => $res];
    }
