警告 move_uploaded_file()：无法在 php 中移动音频文件

Question

我有使用 Recorder.js 的简单 Record Wave 脚本

现在问题是

1. 记录没问题

2. 减少到我的记录还可以

3. 从blob下载记录文件没问题

4. 上传记录文件（这里是问题）

5. 操作系统 ( windows 10 & appserv )

我的上传.php

  <?php

    print $_FILES["audio_data"]["tmp_name"]; //this will print out the received name, temp name, type, size, etc.

    //check if upload folder exist or not

    if(!is_dir("uploads")){

        $res = mkdir("uploads",0777); 

    }

    $size = $_FILES['audio_data']['size']; //the size in bytes

    $input = $_FILES['audio_data']['tmp_name']; //temporary name that PHP gave to the uploaded file

    $output = $_FILES['audio_data']['name'].".wav"; //letting the client control the filename is a rather bad idea

    //move the file from temp name to local folder using $output name

    move_uploaded_file($input, $output)

    ?>

我的 js 文件的一部分

function createDownloadLink(blob) {

    var url = URL.createObjectURL(blob);

    var au = document.createElement('audio');

    var li = document.createElement('li');

    var link = document.createElement('a');

    //name of .wav file to use during upload and download (without extendion)

    var filename = new Date().toISOString();

    //add controls to the <audio> element

    au.controls = true;

    au.src = url;

    //save to disk link

    link.href = url;

    link.download = filename+".wav"; //download forces the browser to donwload the file using the  filename

    link.innerHTML = "Save to disk";

    //add the new audio element to li

    li.appendChild(au);

    //add the filename to the li

    li.appendChild(document.createTextNode(filename+".wav "))

    //add the save to disk link to li

    li.appendChild(link);

您正在使用输出目录作为文件名，因此会引发错误。由于您的上传目录是上传。试着更新一下：$output&nbsp;="uploads/".$_FILES['audio_data']['name'].".wav";
