This was just something I had to setup again recently and I thought I'd post it this time around. This snippet allows for any website utilizing .htaccess to be a go-get repository by redirecting traffic from go get commands (contains go-get=1 in the request) to GitLab or another git repository hosting website. So for example, rather than importing my projects from "gitlab.com/spirited/projectname", I'd use my domain "spirited.io/projectname". That allows me to either redirect human traffic to the project page on my website or redirect go import traffic to the actual repo.

.htaccess

# BEGIN GolangRedirect
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{QUERY_STRING} (^|&)go-get=1($|&)
RewriteRule . /goimport.php [L]
</IfModule>
# END GolangRedirect

goimport.php

<?php 
   $importpath = rtrim(strtok($_SERVER["REQUEST_URI"],'?'), '/');
   $domain     = 'spirited.io';
   $githublink = 'https://gitlab.com/spirited';
   $goImport   = $domain . $importpath . ' git ' . $githublink . $importpath . '.git';
?>
