是否可以从 http 标头中找到文件名
通常在下载文件时,假设使用 QNetworkAccessManager,文件名不会出现在链接的末尾.在这种情况下如何获得正确的文件名.即使链接不包含名称提示,firefox 也会始终使用正确的名称和扩展名下载文件.我们可以使用 mime 类型获得扩展的提示,但文件名呢?
Usually when downloading files, suppose using QNetworkAccessManager, the filename is not present at the end of link. How to get proper file names in that case. Even if link doesn't contain a hint of name, firefox always downloads the file with its proper name and extension. We can get a hint of extention using mime-types but what about file names.
推荐答案
是的.这是 Content-Disposition: 附件;filename=<文件名.ext>
标头.强烈建议将内容类型设置为 application/octet-stream
,这样浏览器及其插件就不会试图打开它.
Yes. It's the Content-Disposition: attachment; filename=<file name.ext>
header. There's a strong suggestion to set the content type to application/octet-stream
so browsers and their plugins are not tempted to open it instead.
