A simple example code for doing by hand:
# index.php (sorry for php here but i was lazy)
# <?php
# $value = 'something from somewhere';
# setcookie("TestCookie", $value);
# ?>
import httpClient
var client = newHttpClient()
# our "login", index.php just sets a cookie
let resp = client.get("http://127.0.0.1:80/ttt/index.php";)
# server sends a cookie useing "Set-Cookie" in its http headers
let cookie = resp.headers["Set-Cookie"]
echo "the cookie: ", cookie
#
# here store the cookie in a file/or load it
#
# now every request we do should contain the cookie
# we set this with "Cookie"
client.headers["Cookie"] = cookie
client.get("http://127.0.0.1:80/ttt/index.php";)
Run
A module that handles stuff for you:
[https://nim-lang.org/1.0.6/cookies.html](https://nim-lang.org/1.0.6/cookies.html)
and last but not least, example code that i use in my small asyncHttpTools
library for handle cookies:
import cookies
export cookies
import strtabs
export strtabs
import cgi # for decodeData
import uri # for encodeQuery
import asynchttpserver
type
Cookie* = StringTableRef
proc parseCookies*(request: Request): Cookie =
## Parses a cookie transmitted by the browser to the server
if request.headers.hasKey("Cookie"):
return parseCookies(request.headers["Cookie"])
else:
return newStringTable()
proc addCookie*(headers: var HttpHeaders, data: StringTableRef) =
## adds cookies to the HttpHeaders.
# format(expires.utc, "ddd',' dd MMM yyyy HH:mm:ss 'GMT'")
headers["Set-Cookie"] = @[] # @[line
var lines: seq[string] = @[]
for key, val in data:
lines.add key & "=" & val.encodeUrl & ";"
headers["Set-Cookie"] = lines
proc decodeData*(data: string): StringTableRef =
## Decodes form data into a StringTable
## TODO dublicated keys are not supported
result = newStringTable()
for key, val in decodeData(data):
result[$key] = $val
proc encodeData*(tab: StringTableRef, usePlus = false; omitEq = true):
string =
## Encodes a StringTable into a form data string
var dat: seq[(string, string)] = @[]
for key, val in tab:
dat.add( (key, val) )
return encodeQuery(dat)
Run
