使用Curl通过PHP发送SMS

<?php
// 设置API密钥
$secretId = "your_secret_id";
$secretKey = "your_secret_key";

// 设置短信参数
$phoneNumber = "your_phone_number";
$templateId = "your_template_id";
$params = array(
    "param1" => "value1",
    "param2" => "value2"
);

// 构造请求参数
$timestamp = time();
$random = mt_rand(100000, 999999);
$sign = md5("secretId=".$secretId."&secretKey=".$secretKey."&timestamp=".$timestamp."&random=".$random);
$data = array(
    "secretId" => $secretId,
    "timestamp" => $timestamp,
    "random" => $random,
    "sign" => $sign,
    "phoneNumber" => $phoneNumber,
    "templateId" => $templateId,
    "params" => $params
);

// 发送请求
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://sms.tencentcloudapi.com/");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($ch);
curl_close($ch);

// 处理响应结果
$response = json_decode($result, true);
if ($response["Response"]["Error"]) {
    echo "短信发送失败：" . $response["Response"]["Error"]["Message"];
} else {
    echo "短信发送成功";
}
?>
