Shortcode tests unavailable (network error)

[queensferryme]

I import the official hugo example site (https://github.com/gohugoio/hugoBasicExample) for testing this theme. However, content/post/rich-content.md result in an issue, presumably related to networking.

This file contains hugo shortcodes for instagram, twitter etc., and these services are sofar unaccessible from China mainland.

Using proxies (with proxychains4) doesn't help on my computer. Hence, this file content/post/rich-content.md is temporarily removed from exampleSite, waiting for future resolvement.

proxychains4 works well on my computer, please check your network

As mentioned by the author of proxychains-ng:

proxychains hooks to dynamically loaded libc.

1. go doesn't even use libc, it uses its own syscall wrappers
2. go doesn't use dynamic linking, it uses static linking

so there's no way we could use this technique with go. the only way to hook into go binaries would be by using ptrace to hook the system calls themselves, which is hairy and platform-dependent - i.e. it means it would be a lot more work to produce and maintain.
so i fear it is out of scope for this utility.

A possible alternative would be using graftcp.

Golang does not use libc, so proxychains-ng won't work. Turns out the solution is actually simple: set env vars like HTTP_PROXY and HTTPS_PROXY etc.
