wp_handle_upload 不接受有效的 mime 类型

Question

我已经尝试了至少 3 种解决方法来让我的 .vcf 文件在 wordpress 中的 wp_handle_upload 函数期间被接受。

1. 添加过滤器和扩展：我尝试了几种类型，包括“text/x-vcard”、“application/vcard”、“text/anytext”。 mime 类型的过滤器添加工作了一段时间，然后再次停止工作。

   add_filter('upload_mimes', array('Daisy', 'daisy_mime_types'), 1, 1);
   public static function daisy_mime_types($mime_types){
     $mime_types['vcf'] = 'text/*'; //Adding .vcf extension
     return $mime_types;
   }  
   

2. 我将 mime 类型作为数组添加到 wp_handle_upload 参数中。

   $vcard_upload = wp_handle_upload( $_FILES["vcard"], array('test_form' => false, 'mimes' => array('vcf' => 'text/*')) );
   

3. 我使用了插件 WP Add Mime Types。

无论采用何种方法，我都会收到以下错误：“抱歉，出于安全原因，不允许使用此文件类型。”但是，如果我使用 WP Media Handler，我可以上传文件，以便通过其他渠道接受 mime 类型。

确认时，mime 类型在可接受的 mime 类型列表中：

    print_r(get_allowed_mime_types())
   ` Array

Answer 1

我认为这可能与在您的 Web 服务器配置中定义 mime 类型的方式有关。我对 ogg（视频文件 .ogv）也有同样的问题，行：

$mime_types['ogv'] = 'video/ogg';

在本地主机上工作正常，但客户端的服务器却不行，最后我发现我必须多写一行：

$mime_types['ogv'] = 'application/ogg';

所以我建议要么检查您的服务器配置，要么（如果不可能的话）盲目检查其他 mime 类型，例如：

$mime_types['vcf'] = 'application/vcf';
