将json字符串转换为URL编码字符串（Rails）

Question

我如何转换此json var

email = {"email":"name@gmail.com"}

进入这个编码的字符串？

%7B%22email%22%3A%22name%40gmail.com%22%7D

Answer 1

当然，您可以使用显示here

的uri库

[2] pry(main)> require 'uri'
=> true
[3] pry(main)> URI.encode('{"email":"name@gmail.com"}')
=> "%7B%22email%22:%22name@gmail.com%22%7D"

Answer 2

使用 CGI.escape ，而不是URI.encode / escape。 URI.encode不会转义JSON数组的括号。

emails = '{"list_1":[{"Jim":"jim@gmail.com"},{"Joe":"joe@gmail.com"}]}'
> URI::encode(emails)
=> "%7B%22list_1%22:[%7B%22Jim%22:%22jim@gmail.com%22%7D,%7B%22Joe%22:%22joe@gmail.com%22%7D]%7D"
> CGI.escape(emails)
=> "%7B%22list_1%22%3A%5B%7B%22Jim%22%3A%22jim%40gmail.com%22%7D%2C%7B%22Joe%22%3A%22joe%40gmail.com%22%7D%5D%7D"
