Codeigniter 3 中的文件上传

Question

我尝试使用 codeigniter 上传 wav 文件。但是我收到了这个错误信息；
The filetype you are attempting to upload is not allowed.

代码如下：

    $config['upload_path'] = getwdir() . 'voices/';
    $config['allowed_types'] = 'wav|mp3';
    $config['max_size'] = 2800000;
    $config['file_name'] = rand();
    $this->upload->initialize($config);
    var_dump($config);
    if ($this->upload->do_upload('file')) {
        var_dump('uploaded');
    }else{
        var_dump($this->upload->display_errors());
    }

var_dump($_FILES['file']);

  array (size=1)
 'file' => 
    array (size=5)
      'name' => string 'blob' (length=4)
      'type' => string 'audio/wav' (length=9)
      'tmp_name' => string '/tmp/phpe2SQi5' (length=14)
      'error' => int 0
      'size' => int 98348

使用具有这些配置值的上传库时：

$config['upload_path'] = 'uploads/';
$config['allowed_types'] = 'wav';
$config['max_size'] = '1000000';
$this->load->library('upload', $config).

如果您尝试上传 .wav 文件（已在 firefox 7.0.1 中测试）。会报错'The filetype you are attempting to upload is not allowed.'.

This can be solved by replacing line 68 in application/config/mimes.php

'wav' => 'audio/x-wav'
 with:
'wav' => array('audio/wav', 'audio/wave', 'audio/x-wav'),

好的，如果您已经尝试过，那么试试这个：

您可以尝试查看 system/libraries/Upload.php 第 199 行：

$this->_file_mime_type($_FILES[$field]);

改为

$this->_file_mime_type($_FILES[$field]); var_dump($this->file_type); die();

然后上传您的 .wmv 文件。它会显示类似 application/octet-stream 之类的内容。将其添加到您的 mimes.php.
