URL编码总结

阮一峰老师写过一篇《关于URL编码》，不过该篇文章较为久远，且现在浏览器升级迭代迅速，文中不少案例需要进行修正。

一、问题的由来

URL就是网址，只要上网，就一定会用到。

通常，URL只能使用英文字母、阿拉伯数字和某些标点符号，不能使用其他文字和符号。比如，世界上有英文字母的网址“http://www.abc.com”，但是没有希腊字母的网址“http://www.aβγ.com”（读作阿尔法-贝塔-伽玛.com）。这是因为网络标准RFC 1738做了硬性规定：

Stuff I wish I'd known sooner about service workers

I recently had several days of extremely frustrating experiences with service workers. Here are a few things I've since learned which would have made my life much easier but which isn't particularly obvious from most of the blog posts and videos I've seen.

I'll add to this list over time – suggested additions welcome in the comments or via twitter.com/rich_harris.

Use Canary for development instead of Chrome stable

~~Chrome 51 has some pretty wild behaviour related to console.log in service workers. Canary doesn't, and it has a load of really good service worker related stuff in devtools.~~

	# A modification of https://gist.github.com/1064640/ to include a white-list of URLs
	#
	# Despite the W3C guidance suggesting that a list of origins can be passed as part of
	# Access-Control-Allow-Origin headers, several browsers (well, at least Firefox)
	# don't seem to play nicely with this.
