将Chrome中记录的WAV文件保存到服务器

客户端Javascript函数上传WAV Blob：

function upload(blob) {  var xhr=new XMLHttpRequest();  xhr.onload=function(e) {      if(this.readyState === 4) {          console.log("Server returned: ",e.target.responseText);      }  };  var fd=new FormData();  fd.append("that_random_filename.wav",blob);  xhr.open("POST","<url>",true);  xhr.send(fd);}

PHP文件

upload_wav.php

<?php// get the temporary name that PHP gave to the uploaded file$tmp_filename=$_FILES["that_random_filename.wav"]["tmp_name"];// rename the temporary file (because PHP deletes the file as soon as it's done with it)rename($tmp_filename,"/tmp/uploaded_audio.wav");?>

之后，您可以播放文件

/tmp/uploaded_audio.wav

但要记住！

/tmp/uploaded_audio.wav

www-data

chmod("/tmp/uploaded_audio.wav",0755);

到PHP的末尾（在PHP end标签之前

?>

希望这可以帮助。
