让 curl 支持 HTTP2 我们需要安装 nghttp2（http2 的 C 语言库）

源码安装

安装 nghttp2

git clone https://github.com/tatsuhiro-t/nghttp2.git

cd nghttp2

autoreconf -i

automake

autoconf

./configure

make

sudo make install

编译 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

sudo make && make install

编译时注意观察

HTTP2 support: enabled (nghttp2)

echo '/usr/local/lib' > /etc/ld.so.conf.d/local.conf

ldconfig

验证

curl --version
