curl 支持 http2

讓 curl 支持 HTTP2 咱們須要安裝 nghttp2（http2 的 C 語言庫）

源碼安裝

安裝 nghttp2

git clone https://github.com/tatsuhiro-t/nghttp2.git
cd nghttp2
autoreconf -i
automake
autoconf
./configure
make
sudo make install

編譯 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

編譯時注意觀察
HTTP2 support: enabled (nghttp2)

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

驗證

curl --version
