今天我們用到了新的 PHP 方法

curl

可以輸入網址當成是一次網頁請求完成 POST 或 傳遞 GET 參數 的任務，甚至可以拿來當爬蟲取得資料

如果是取得該連結的頁面原始碼

<?php
$url = "輸入連結";
$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$output = curl_exec($ch);
curl_close($ch);

echo $output; // 把網頁內容印出來

如果是打 GET 參數過去

<?php
$url = "http://example.com/";
$data_array = array("acc"=>"F", "pwd"=>"123");
$url = $url . http_build_query($data_array); 
// 組出 http://sample.com/?acc=F&pwd=123

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$output = curl_exec($ch);
curl_close($ch);

echo $output; // 把網頁內容印出來

如果是打 POST 過去

<?php
$url = "http://example.com/";
$data_array = array("username"=>"Falcon", "password"=>"123456");
$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($post_data)); 
$output = curl_exec($ch); 
curl_close($ch);

echo $output; // 把網頁內容印出來

來看簡訊王的 API 文件

https://www.kotsms.com.tw/index.php?selectpage=pagenews&kind=4&viewnum=238

看起來很簡單只要有網址打 GET 參數過去，就成功發送囉！還可以直接用網頁來測試，那直接來看物件設計吧：

<?php
/**
 * 串接簡訊王 API 用來發送簡訊
 * https://www.kotsms.com.tw/
 */
class SMS {
    
    private $content;
    private $phoneNumber;
    private $username;
    private $password;
    private $responseUrl = ''; // optional

    function __construct($username, $password){
        $this->username = $username;
        $this->password = base64_decode($password);
    }

    function setContent($content){
        $this->content = $content;
    }

    function setPhoneNumber($phoneNumber){
        $this->phoneNumber = $phoneNumber;
    }

    function setResponseUrl($responseUrl){
        $this->responseUrl = $responseUrl;
    }

    function send(){
        if ( $this->content=='' || !preg_match('/^09([0-9]{8})$/', $this->phoneNumber) || $this->username=='' || $this->password=='' ){
            return 'ERROR Params.';
        }

        $data = array(
            'username' =>$this->username,
            'apikey'   =>$this->password,
            'dstaddr'  =>$this->phoneNumber,
            'response' =>$this->responseUrl,
            'smbody'   =>iconv("UTF-8","big5//TRANSLIT",$this->content));

        $querystring = http_build_query($data);
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, "http://api.kotsms.com.tw/kotsmsapi-1.php?".$querystring);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        $result = curl_exec($ch);
        curl_close($ch);

        $this->phoneNumber = '';
        $this->content = '';
        
        return $result;
    }
}

記得 composer dump 把 SMS 加入函式庫

使用上也不難 在 Config 開好參數 SMS_USERNAME 與 SMS_PASSWORD
填好 $content 與目標 $phoneNumber 電話號碼即可

$SMS = new SMS(Config::SMS_USERNAME, Config::SMS_PASSWORD);
$SMS->setContent($content);
$SMS->setPhoneNumber($phoneNumber);
$SMS->send();
