IE 11下载文件中文乱码解决(go/php)

IE 11下载文件的时候发现乱码.

网上查了下资料，了解了一下，主要是user-agent变了，不再是MSIE，面是rv:11.0这样，所以只要服务端判断出是IE 11，处理跟MSIE一样。

GO:

func setDownloadFileName(w http.ResponseWriter, fileName, agent string) {

    if strings.Contains(agent, "MSIE") {

        fileName = url.QueryEscape(fileName)

        fileName = strings.Replace(fileName, "+", "%20", -1)

    }

    if strings.Contains(agent, "rv:") && strings.Contains(agent, "Gecko") {

        fileName = url.QueryEscape(fileName)

        fileName = strings.Replace(fileName, "+", "%20", -1)

    }

    w.Header().Set("Content-Disposition", "attachment;filename=\""+fileName+"\"")

}

PHP:

$ua = isset ( $_SERVER ["HTTP_USER_AGENT"] ) ? $_SERVER ["HTTP_USER_AGENT"] : '';<span style="white-space:pre"></span>if (preg_match ( "/MSIE/", $ua )) {<span style="white-space:pre"></span>$file_name = rawurlencode ( $file_name );<span style="white-space:pre"></span>header ( 'Content-Disposition: attachment; filename="' . $file_name . '"' );} else if (preg_match ( "/Firefox/", $ua )) {<span style="white-space:pre"></span>header ( 'Content-Disposition: attachment; filename*="utf8\'\'' . $file_name . '"' );} elseif (stripos ( $ua, 'rv:' ) > 0 && stripos ( $ua, 'Gecko' ) > 0) {<span style="white-space:pre"></span>$file_name = rawurlencode ( $file_name );<span style="white-space:pre"></span>header ( 'Content-Disposition: attachment; filename="' . $file_name . '"' );} else {<span style="white-space:pre"></span>header ( 'Content-Disposition: attachment; filename="' . $file_name . '"' );}
