h3get

A dead simple curl-like HTTP/3 client tool I use for debugging HTTP/3 servers. It can be set to explicitly use IPv4 or IPv6.

Note

This program uses a modified version of the quic-go library to allow for explicitly setting the network string for the ListenUDP function through the QUIC_GO_CLIENT_NETWORK_TYPE environment variable.

Build

Dependencies

• Git
• Go 1.21 or later

Instructions

Clone the repository and enter it:

git clone https://github.com/nixigaj/h3get
cd h3get

Build the binary:

Usage

To specify URL, use the --url or -u flag.

To specify explicit usage of IPv4 or IPv6, use the --ipv4 or -4, and --ipv6 or -6 flags.

To specify timeout for request in seconds, use the --timeout or -t flag.

To use curl as user agent, use the --curl or -c flag.

To print usage use the --help or -h flag.
