Php 解释为文档但使用MIME类型应用程序/csv传输的资源

我有一个下载CSV文件的按钮。 该文件似乎下载良好，但我得到以下警告。 此警告似乎只出现在chrome中

解释为文档但使用MIME类型应用程序/csv传输的资源：

这是我设置CSV标题的地方

/**
* Set the PHP mime header
*
* This will overwrite any previous headers
*
* @param string $header any custom headers that need to be set
*
* @return void
* @access public
*/
function setHeader($header='')
{
    if ($header) {
        // set custom headers
        header($header);
    } else {
        header('Content-Type: application/csv');
        header('Content-Disposition: attachment; filename="'.$this->_filename.'";');

        //This is known that Internet Explorer has problems with SSL connection (https).
        //http://support.microsoft.com/default.aspx?scid=kb;en-us;812935
        //http://support.microsoft.com/default.aspx?scid=kb;en-us;316431
        // do not send no cache header in https for IE

        // get protocol information
        $url_info = parse_url(current_url());
        $protocol = (isset($url_info['scheme'])) ? $url_info['scheme'] : NULL;
        $using_ie6_8 = isset ($_SERVER['HTTP_USER_AGENT']) ? preg_match('/(MSIE\s[0-8]+\.)/', $_SERVER['HTTP_USER_AGENT']) : FALSE;
        if (!is_null($protocol) && $protocol == 'https' && $using_ie6_8) {
            header('Cache-Control: private, max-age=0, must-revalidate');
            header('Pragma: private');
            header('Expires: '.gmdate('D, d M Y H:i:s', time()-3600).' GMT');

        }

    }

}//end setHeader()

如果您在

中有下载csv文件的链接，请在

中添加“下载”属性，如果您希望这样做，请确保您的目标浏览器支持按钮属性（并非所有浏览器都支持）！
