API ngxescape_uri does not work as desired

guanglinlv

I need to encode some string using URL style %XX encoding. but ngxescape_uri doest encode the comma character.

eg:

./bin/resty -e 'ngx.say(ngx.escape_uri([[{"name":"value","hello":"world"}]]))'

%7B%22name%22%3A%22value%22,%22hello%22%3A%22world%22%7D

it's unexpected to me, is there any limitation on this API.

then i have to write a simple implement by myself.

url.lua

local _M = {}
function _M.escape (str)
str = string.gsub (str, "\n", "\r\n")
str = string.gsub (str, "([^%w ])",
function (c) return string.format ("%%%02X", string.byte(c)) end)
str = string.gsub (str, " ", "+")
return str
end
function _M.unescape (s)
s = string.gsub(s, "+", " ")
s = string.gsub(s, "%%(%x%x)", function (h)
return string.char(tonumber(h, 16))
end)
return s
end
return _M

./bin/resty -e 'local url = "" "url" ngx.say(url.escape([[{"name":"value","hello":"world"}]]))'

%7B%22name%22%3A%22value%22%2C%22hello%22%3A%22world%22%7D

Thanks.
