Sometimes $cookies.set is not consistent with `document.cookie=`

[lifubang]

When we use document.cookie='email=lifubang@acmcoder.com', the value of document.cookie is email=lifubang@acmcoder.com; But when we use this.$cookies.set('email', 'lifubang@acmcoder.com'), the value of document.cookie is email=lifubang%40acmcoder.com.

It's ok when we just use cookie in front-end, but the back-end will get an inconsistent cookie value when we use vue-cookies to replace document.cookie= in front-end, it would cause the back-end to upgrade their code.

The cookie value string can use encodeURIComponent() to ensure that the string does not contain any commas, semicolons, or whitespace (which are disallowed in cookie values).

encodeURIComponent/decodeURIComponent escape sequences (e.g. comma, quotes, [], : , ; etc)

back-end transcoding

Java Example:

URLDecoder.decode("lifubang%40acmcoder.com", "utf-8");

PHP Example:

urldecode("lifubang%40acmcoder.com")

The cookie value string can use encodeURIComponent() to ensure that the string does not contain any commas, semicolons, or whitespace (which are disallowed in cookie values).

I think the operation document.cookie=*** will handle these cases by itself. You can try it in chrome console window.

back-end transcoding

Yes, back-end can decode it correctly. My thought is that we should not force the back-end to change the code when I use vue-cookies to replace document.cookie=.

I agree with @lifubang in that I am having issues with this as well.

I don't mind if the value is encoded in the cookie storage, but the decode does not work for me when I get cookies back. When I use Vue.$cookies.get() it returns the escaped strings for me, so the functionality is ruined.

My understanding is that the cookie stores a standard string and handles all required escaping itself as well.

but the decode does not work for me when I get cookies back

Yes, we may hit this issues when we read the cookie created by the back-end. So I update the commit of the #67 .

当cookie含有 ASCII 特殊符号时，encodeURIComponent会对key or value 进行编码，这样会导致接下来的请求后端cookies校验无法通过，希望不要对@&=+$#这些特殊符号进行编译。
