curl 支持 HTTP2

curl 命令支持 HTTP2

执行以下命令：

sudo apt-get install -y tmux curl vim wget htop git

首先使用 curl 请求 https://nghttp2.org （使用了 http2）。但是结果却是返回了 HTTP1.1 响应：

$ curl -I https://nghttp2.org/  HTTP/1.1 200 OK Date: Fri, 04 Dec 2015 00:00:06 GMT Content-Type: text/html Content-Length: 6680 Last-Modified: Thu, 26 Nov 2015 15:28:33 GMT Etag: "56572521-1a18" Accept-Ranges: bytes X-Backend-Header-Rtt: 0.000642 Server: nghttpx nghttp2/1.5.1-DEV Via: 1.1 nghttpx strict-transport-security: max-age=31536000

如果使用 http2 ，会给我们返回一个协议不支持的错误。

$ curl --http2 -I https://nghttp2.org/ # Unsupported protocol error

安装 nghttp2

安装 nghttp2 ad 工具（http2 的 C 库支持）：

# Get build requirements # Some of these are used for the Python bindings # this package also installs sudo apt-get install g++ make binutils autoconf automake autotools-dev libtool pkg-config /   zlib1g-dev libcunit1-dev libssl-dev libxml2-dev libev-dev libevent-dev libjansson-dev /   libjemalloc-dev cython python3-dev python-setuptools  # Build nghttp2 from source git clone https://github.com/tatsuhiro-t/nghttp2.git cd nghttp2 autoreconf -i automake autoconf ./configure make sudo make install

更新到最新的 curl 版本：

cd ~ sudo apt-get build-dep curl wget http://curl.haxx.se/download/curl-7.46.0.tar.bz2 tar -xvjf curl-7.46.0.tar.bz2 cd curl-7.46.0 ./configure --with-nghttp2=/usr/local --with-ssl make sudo make install sudo ldconfig

通过 ldconfig 命令使得 curl 命令可以正常工作，但是你也可以尝试如下命令：

# Try this out first curl --http2 -I nghttp2.org  # If you get errors, try setting this constant # to tell curl where to find shared libraries LD_LIBRARY_PATH=/usr/local/lib /usr/local/bin/curl --http2 -I nghttp2.org

测试 curl

LD_LIBRARY_PATH=/usr/local/lib /usr/local/bin/curl --http2 -k -I -H "Host: example.com" https://localhost > HTTP/2.0 200 > server:nginx/1.9.7 > date:Fri, 04 Dec 2015 02:20:54 GMT > content-type:text/html > content-length:12 > last-modified:Fri, 04 Dec 2015 02:11:11 GMT > etag:"5660f63f-c" > accept-ranges:bytes
