How to decode golang url.QueryEscape data in javascript?
问题
我在JS端有一个经过url.QueryEscape处理的字符串。
url.QueryEscape将空格替换为+号。但在decodeURIComponent中，它们并不会被转换回空格。我应该手动将所有的+号替换为空格吗？正确的解码方法是什么？
英文:
I have a string in JS side which is url.QueryEscaped.
Spaces were replaced with + sign by url.QueryEscape. They don't get converted back to space in decodeURIComponent. Should I manually do a string replace all + with space? What is the right way to decode it?

一种简单的方法是在解码之前将所有的+字符替换为空格。例如：
decodeURIComponent("%2f+%2b".replace(/\+/g, " "))
将正确地将字符串解码为"/ +"。请注意，在解码之前执行替换是必要的，因为字符串中可能存在编码的+字符。
英文:
One simple method is to replace all the + characters with spaces prior to decoding. For example:
decodeURIComponent("%2f+%2b".replace(/\+/g, " "))
will correctly decode the string to "/ +". Note that it is necessary to perform the replacement prior to decoding, since there could be encoded + characters in the string.

如果你控制Go端，可以使用url.PathEscape，然后你可以简单地使用decodeURIComponent，不需要任何额外的东西。
英文:
If you control Go side, use url.PathEscape and then you can simply use decodeURIComponent without anything extra.
