# HTTP3 (and QUIC)
|

[HTTP/3 Explained](https://daniel.haxx.se/http3-explained/) - the online free
|

book describing the protocols involved.

[QUIC implementation](https://github.com/curl/curl/wiki/QUIC-implementation) -
|

the wiki page describing the plan for how to support QUIC and HTTP/3 in curl
|
||
|
|
and libcurl.

## QUIC libraries
|
||
|
|
|
||
|
|
QUIC libraries we're experiementing with:
|
||
|
|
|
||
|
|
[ngtcp2](https://github.com/ngtcp2/ngtcp2)
|
||
|
|
|
||
|
|
[quiche](https://github.com/cloudflare/quiche)
|
||
|
|
|
||
|
|
## Experimental!
|
||
|
|
|
||
|
|
HTTP/3 and QUIC support in curl is considered **EXPERIMENTAL** until further
|
||
|
|
notice. It needs to be enabled at build-time.
|
||
|
|
|
||
|
|
Further development and tweaking of the HTTP/3 support in curl will happen in
|
||
|
|
in the master branch using pull-requests, just like ordinary changes.

# ngtcp2 version
|
||
|
|
|
||
|
|
## Build
|
||
|
|
|
||
|
|
Build (patched) OpenSSL
|
||
|
|
|
||
|
|
% git clone --depth 1 -b openssl-quic-draft-23 https://github.com/tatsuhiro-t/openssl
|
||
|
|
% cd openssl
|
||
|
|
% ./config enable-tls1_3 --prefix=<somewhere1>
|
||
|
|
% make
|
||
|
|
% make install_sw
|
||
|
|
|
||
|
|
Build nghttp3
|
||
|
|
|
||
|
|
% cd ..
|
||
|
|
% git clone https://github.com/ngtcp2/nghttp3
|
||
|
|
% cd nghttp3
|
||
|
|
% autoreconf -i
|
||
|
|
% ./configure --prefix=<somewhere2> --enable-lib-only
|
||
|
|
% make
|
||
|
|
% make install
|
||
|
|
|
||
|
|
Build ngtcp2
|
||
|
|
|
||
|
|
% cd ..
|
||
|
|
% git clone https://github.com/ngtcp2/ngtcp2
|
||
|
|
% cd ngtcp2
|
||
|
|
% autoreconf -i
|
||
|
|
% ./configure PKG_CONFIG_PATH=<somewhere1>/lib/pkgconfig:<somewhere2>/lib/pkgconfig LDFLAGS="-Wl,-rpath,<somewhere1>/lib" --prefix=<somewhere3>
|
||
|
|
% make
|
||
|
|
% make install
|
||
|
|
|
||
|
|
Build curl
|
||
|
|
|
||
|
|
% cd ..
|
||
|
|
% git clone https://github.com/curl/curl
|
||
|
|
% cd curl
|
||
|
|
% ./buildconf
|
||
|
|
% LDFLAGS="-Wl,-rpath,<somewhere1>/lib" ./configure --with-ssl=<somewhere1> --with-nghttp3=<somewhere2> --with-ngtcp2=<somewhere3>

# quiche version
|
||
|
|
|
||
|
|
## build
|
||
|
|
|
||
|
|
Clone quiche and BoringSSL:
|
||
|
|
|
||
|
|
% git clone --recursive https://github.com/cloudflare/quiche
|
||
|
|
|
||
|
|
Build BoringSSL (it needs to be built manually so it can be reused with curl):
|
||
|
|
|
||
|
|
% cd quiche/deps/boringssl
|
||
|
|
% mkdir build
|
||
|
|
% cd build
|
||
|
|
% cmake -DCMAKE_POSITION_INDEPENDENT_CODE=on ..
|
||
|
|
% make
|
||
|
|
% cd ..
|
||
|
|
% mkdir -p .openssl/lib
|
||
|
|
% cp build/crypto/libcrypto.a build/ssl/libssl.a .openssl/lib
|
||
|
|
% ln -s $PWD/include .openssl
|
||
|
|
|
||
|
|
Build quiche:
|
||
|
|
|
||
|
|
% cd ../..
|
||
|
|
% QUICHE_BSSL_PATH=$PWD/deps/boringssl cargo build --release --features pkg-config-meta
|
||
|
|
|
||
|
|
Clone and build curl:
|
||
|
|
|
||
|
|
% cd ..
|
||
|
|
% git clone https://github.com/curl/curl
|
||
|
|
% cd curl
|
||
|
|
% ./buildconf
|
||
|
|
% ./configure LDFLAGS="-Wl,-rpath,$PWD/../quiche/target/release" --with-ssl=$PWD/../quiche/deps/boringssl/.openssl --with-quiche=$PWD/../quiche/target/release
|
||
|
|
% make
|
||
|
|
|
||
|
|
## Run
|
||
|
|
|
||
|
|
Use HTTP/3 directly:
|
||
|
|
|
||
|
|
curl --http3 https://nghttp2.org:8443/
|
||
|
|
|
||
|
|
Upgrade via Alt-Svc:
|
||
|
|
|
||
|
|
curl --alt-svc altsvc.cache https://quic.aiortc.org/
|
||
|
|
|
||
|
|
