通过Ajax传递Blob以生成文件

尝试将文件上传为表单数据

audioRecorder.exportWAV(function(blob) {      var url = (window.URL || window.webkitURL).createObjectURL(blob);      console.log(url);      var filename = <?php echo $filename;?>;      var data = new FormData();      data.append('file', blob);      $.ajax({        url :  "lib/vocal_render.php",        type: 'POST',        data: data,        contentType: false,        processdata: false,        success: function(data) {          alert("boa!");        }, error: function() {          alert("not so boa!");        }      });});

。

<?phpif(isset($_FILES['file']) and !$_FILES['file']['error']){    $fname = "11" . ".wav";    move_uploaded_file($_FILES['file']['tmp_name'], "../ext/wav/testes/" . $fname);}?>
