我能使用CURL获取HTTP/2标头吗？

现在我curl -I用来检索标题.

在即将采用的浏览器采用HTTP/2时,网站会采用不同的方式为HPACK提供标头,这会使我对curl命令的使用无效吗？

我相信这取决于卷曲版本.在curl 7.36.x IIRC中添加了HTTP/2？并非所有的发行版都有这个版本？

这是针对https://google.com的 HTTP/2卷曲7.41.0

curl --http2 -I -v https://google.com
* Rebuilt URL to: https://google.com/
*   Trying 173.194.123.1...
* Connected to google.com (173.194.123.1) port 443 (#0)
* ALPN, offering h2-14, http/1.1

* ALPN, server accepted to use h2-14
* Server certificate:

编辑:更正,卷曲--http2需要编译为nghttp2工作https://nghttp2.org/
