php implements sending text messages

In this article, we will reveal the operation of using PHP to send SMS verification codes. Do you think that when you used to register an account on a mobile app, when you clicked to send the verification code, it would take a few seconds? With a beep, the verification code is sent to your phone. Do you think it’s amazing?

1. Since we need to write the login and registration API interface in our business, we learned about the front-end and back-end interaction process of mobile phone number registration;

( 1) The user operates the client and clicks to send the verification code, (then the client sends an ajax request, and the button is in 60s silent time)

(2) The back-end logic layer accepts the passed mobile phone number and verifies whether the format is Legal, enter the database to match whether it exists

(3) Generate a verification code, store it in the session, and then send curl to the third-party SMS interface link

(4) Configure the third-party SMS platform, Send verification code information to the user with the specified mobile phone number

2. Today we mainly explain the configuration of the third-party platform and the logic of background processing;

3. The selected third-party platform is: (You can also choose other platforms, the principles are almost similar)

(1) Saidi Cloud Communication (https://www.mysubmail.com)

(2) Register, real-name authentication, enter products and services, create a new template, and its template syntax can be viewed in its supporting documentation

(3) Go to " Create/Manage AppIdD" column, create and enable the project, and then generate the default "APPID" and "APPKEY"

Backend logic development:

Core: Create verification code -> Encapsulate POST request function -> Send verification code to third-party platform -> Then forward it to the user’s mobile phone by the third party

* Since Sina blog does not support markdown, only the core code and the places where you have stepped on the big pits are posted:

)

private function sendMessage()
 {
        $appId = "xxxxx";
        $appKey = "36426a9xxxxxxxxxxxx7bed8583a3c";
        $code = $this->makeCode(6);

        $data = [
            "appid" => $appId,
            "to" => $this->phone,
            "project" => "FoJ494",
            "vars" => '{"code":' . $code . ',"time":"60"}',
            "signature" => $appKey,
        ];

        $res = $this->httpRequest($data);

        var_dump($res);
}

)

private function httpRequest($data)
{
    $curl = curl_init();
    curl_setopt($curl, CURLOPT_URL, $this->RequestUrl);
    curl_setopt($curl, CURLOPT_HEADER, 0);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);

    if (isset($data)) {
        curl_setopt($curl, CURLOPT_POST, 1);
        curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
    }

    $res = curl_exec($curl);
    var_dump(curl_error($curl)); //打印请求错误
    curl_close($curl);
    return $res;
}

'SSL certificate problem: unable to get local issuer certificate' , then don't worry, continue the operation according to the official channels:

, continue to report errors! !

 curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, true); 
   curl_setopt($curl, CURLOPT_CAINFO, dirname(__FILE__) . '/cacert.pem'); 
   curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 2);
