php语法如何调用华为云短信接口实现短信发送

$params = array(
  "from" => "<签名名称>", //短信签名，从控制台中获取
  "to" => "<手机号码>", //接收短信的手机号码
  "templateId" => "<模板ID>", //短信模板ID，从控制台中获取
  "templateParas" => array("<参数1>", "<参数2>") //短信模板替换参数，具体参数值由模板定义
);

function sendSms($accessKeyId, $accessKeySecret, $params) {
  $url = "https://api..myhuaweicloud.com/sms/batchSendSms/v1"; //API接口地址
  $headers = array(
    "Content-type: application/json;charset=utf-8", //请求Body数据格式
    "X-WSSE: xxxxxx"  //使用API密钥认证
  );
  $accessKey = base64_encode($accessKeyId . ':' . $accessKeySecret);
  array_push($headers, "Authorization: WSSE realm="SDP",profile="UsernameToken",type="Appkey"",
  //使用API密钥认证，请将参数替换为实际值
  "X-WSSE: UsernameToken Username="{$accessKeyId}",PasswordDigest="{$accessKey}",Nonce="xxxxxxxxxxx",Created="xxxxxxxxxxx"");
  $params_str = json_encode($params); //参数转化为json格式
  $ch = curl_init($url); //初始化curl
  curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
  curl_setopt($ch, CURLOPT_POSTFIELDS,$params_str); //请求Body部分
  curl_setopt($ch, CURLOPT_RETURNTRANSFER,true);
  curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
  $result = curl_exec($ch);
  curl_close($ch);
  return $result;
}
