feat(full_url_for): utilize hexo-util module

[SukkaW]

What does it do?

hexojs/hexo-util#84

Returns a url with the config.url prefixed.

Use Case 1

link[canonical] tag, which is one of a best practice for SEO, needs an absolute url of current page.

According to the test carried out by theme NexT team:

{{ page.permalink }} works on every page exclude index and archive page.
{{ url }} is everywhere.

A full_url_for(page.path) can be used in this case.

Use Case 2

Use url to share the post at social media, which is similar to the first case:

• Sina Weibo http://service.weibo.com/share/share.php?appkey=&title=[title]&url=[url]&pic=[site logo]&searchPic=false&style=simple
• Twitter https://twitter.com/intent/tweet?text=[title]&url=[url]
• Facebook https://www.facebook.com/sharer/sharer.php?u=[url]
• Telegram https://t.me/share/url?url=[url]&text=[title]

Absolute urls are needed for [url] and [site logo], and full_url_for(page.path) & full_url_for(${site_logo_url}) can be used.

Use Case 3

All examples of structured data (Image, Page path...) and open-graph use absolute urls. If they are best practices, then full_url_for helper can be used.

How to test

git clone -b full_url_for https://github.com/sukkaw/hexo.git
cd hexo
npm install
npm test

Screenshots
