Twilio 如何在php中通过CURL使用twillo notify API发送批量消息？

我想在php中使用CURL使用twillio notify API发送批量消息，我正在尝试以下代码：

$data = [];
    $data['ToBinding'] =  array("binding_type"=>"sms", "address"=>"+12013318779");
    $data['Body'] ="test";
    $ch = curl_init("https://notify.twilio.com/v1/Services/ISXXXXXXXXXXXXXXXXXX/Notifications");
    curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");    
    curl_setopt($ch, CURLOPT_USERPWD,'XXXXXXXXXXXXXXXXXXX:XXXXXXXXXXXXXXXXXXX');
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/x-www-form-urlencoded')); 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    $resultData = curl_exec($ch);

我认为我对

CURLOPT_POSTFIELDS

做了一些错误，但我尝试了每一件事来改变这一点，但每次我都得到以下回应：

{"code": 20001,
"message": "At least one parameter among Identity, Tag, and ToBinding must be specified",
"more_info": "https://www.twilio.com/docs/errors/20001",
"status": 400}

你们能帮帮我吗

ToBinding

要求将数据编码为JSON。请尝试以下操作：

$data['ToBinding'] =  json_encode(array("binding_type"=>"sms", "address"=>"+12013318779"));

希望有帮助
