jsで作ったblobをphpに送信

JavaScript

Posted at 2019-11-24

blob => {
   const xhr = new XMLHttpRequest();
   const formData = new FormData();
   formData.append('audio', blob, 'input.wav');

   xhr.open('POST', '/upload.php', true);
   xhr.send(formData);
}

これだけ

xhr.setRequestHeader('Content-Type', 'multipart/form-data; charset=utf-8; boundary=' + Math.random().toString().substr(2));

これをつけるとbinaryにならず送信できない
