秒滴短信验证码发送PHP接口实例代码，很精简

登陆秒滴官网后可以获得相关信息

看精简的发送代码，就两个函数实现发送

date_default_timezone_set("Asia/Shanghai");
//http post
function curl_post($postUrl,$data,$header = array()){
	$ch = curl_init();
	curl_setopt($ch, CURLOPT_URL,$postUrl);
	curl_setopt($ch, CURLOPT_HEADER, 0);
	curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
	curl_setopt($ch, CURLOPT_POST, 1);
	curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
	if(strpos($postUrl,"https") !== false){
		curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
		curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
	}
	if(count($header)>0){
		curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
	}
	$data = curl_exec($ch);
	curl_close($ch);
	return $data;
}

//发送用户注册的验证码
function sendsmscode($tel,$code){
	$sms = array(
		"url"	=> "https://api.miaodiyun.com/20150822/industrySMS/sendSMS",//固定、无需修改
		"sid"	=> "53c412f78a7143a585014578a4000000", //对应官网后台的 ACCOUNT SID
		"token"	=> "8b7c4094d39c4141aa41a91fd8000000", //对应官网后台的 AUTH TOKEN
	);
	$timespan = date("YmdHis");
	$sign = md5("{$sms['sid']}{$sms['token']}{$timespan}");
	$data = array(
		"accountSid"	=>$sms['sid'],
		"templateid"	=>"318247587",
		"param"			=>"{$code},2",//验证码、时长(分)
		"to"			=>$tel,
		"timestamp"		=>$timespan,
		"sig"			=>$sign,
		"respDataType"	=>"JSON",
	);
	$fields_string = "";
    foreach ($data as $key => $value) {
        $fields_string .= $key . '=' . $value . '&';
    }
    rtrim($fields_string, '&');

	$header = array(
		"Content-type: application/x-www-form-urlencoded",
		"Accept: application/json"
	);
	$json = curl_post($sms['url'],$fields_string,$header);
	if(strpos($json,"{")!==false){
		$json = substr($json,strpos($json,"{"));
	}
	return json_decode($json,true);
}

$x = sendsmscode("18221228706","8652");
header("Content-type:text/html;charset=utf-8");
var_dump($x);

正确后返回

array(5) { ["respCode"]=> string(5) "00000" ["respDesc"]=> string(15) "请求成功。" ["failCount"]=> string(1) "0" ["failList"]=> array(0) { } ["smsId"]=> string(32) "a395adf8c1874ef59baa0959637845d0" }
