How to get a cookie value in google apps script? - json

Question

I'm having difficulty parsing a JSON string with nested arrays. here is an example of the JSON
const allHeaders = {"Strict-Transport-Security":"max-age=31536000","Timing-Allow-Origin":"*","s_ip":"1.5.295.221","Server":"Asia","Vary":"Accept-Encoding","x-application-context":"shop-buyer-s.7001","s_group":"buyer-sessio","Content-Language":"zh-CN","Access-Control-Allow-Headers":"Origin, x-ua, x-umidtoken, x-csrf-token, X-Requested-With, Content-Type, Accept","Set-Cookie":["hms_cid=80dcf576-a581-4d43-8302-1605fe36565c; Domain=.hms.zn; Expires=Sun, 09-Jul-2023 04:39:13 GMT; Path=/","hms_sid=112120422020a413958ddf33139b516b; Domain=.hms.zn; Path=/; HttpOnly","_tb_token_=e8eafb9bebe63; Domain=.hms.zn; Path=/; HttpOnly"],"Transfer-Encoding":"chunked","object-status":"ttl=2592000,age=42,gip=121.43.99.68","Connection":["keep-alive","Transfer-Encoding"],"s_tag":"285873024335988|0^|^^","s_tid":"21410a7016573415536295456ef332","eagleeye-traceid":"21410a7016573415536295456ef332","s_v":"4.0.2.0","Content-Encoding":"gzip","P3P":"CP='CURa ADMa DEVa PSAo PSDo OUR BUS UNI PUR INT DEM STA PRE COM NAV OTC NOI DSP COR'","Date":"Sat, 09 Jul 2022 04:39:13 GMT","Access-Control-Max-Age":"3600","s_ucode":"Asia:CENTER","Access-Control-Allow-Methods":"POST, GET, OPTIONS, DELETE","Content-Type":"text/html;charset=UTF-8","s_status":"STATUS_NOT_EXISTED"}
I need to get the number hms_sid=
exmple: 112120422020a413958ddf33139b516b
I'm trying
const sid = allHeaders['Set-Cookie']

Answer 1

It is unlikely that hms_sid would always appear as the second tuple in the cookie list. Use Array.filter() to locate it, then get the first matching cookie and extract the value with String.match(), testing for missing values, like this:
function test() {
console.log(getCookieTokenValue_(allHeaders, 'hms_sid'));
}
function getCookieTokenValue_(headers, token) {
const tokenRegex = new RegExp('\\b' + token + '=(\\w+)');
const cookies = headers['Set-Cookie'];
const tokens = cookies.filter(cookie => cookie.match(tokenRegex));
return tokens.length ? tokens[0].match(tokenRegex)[1] : null;
}

Answer 2

I'm pretty sure google apps script is just javascript so here's my code:
let cookie = allHeaders['Set-Cookie'][1];
let tokens = cookie.split(";");
let sidString = tokens[0].split("=");
let sid = sidString[1];
Here is how I did it:
Given:
const allHeaders = {
"Strict-Transport-Security": "max-age=31536000",
"Timing-Allow-Origin": "*",
"s_ip": "1.5.295.221",
"Server": "Asia",
"Vary": "Accept-Encoding",
"x-application-context": "shop-buyer-s.7001",
"s_group": "buyer-sessio",
"Content-Language": "zh-CN",
"Access-Control-Allow-Headers": "Origin, x-ua, x-umidtoken, x-csrf-token, X-Requested-With, Content-Type, Accept",
"Set-Cookie": ["hms_cid=80dcf576-a581-4d43-8302-1605fe36565c; Domain=.hms.zn; Expires=Sun, 09-Jul-2023 04:39:13 GMT; Path=/", "hms_sid=112120422020a413958ddf33139b516b; Domain=.hms.zn; Path=/; HttpOnly", "_tb_token_=e8eafb9bebe63; Domain=.hms.zn; Path=/; HttpOnly"],
"Transfer-Encoding": "chunked",
"object-status": "ttl=2592000,age=42,gip=121.43.99.68",
"Connection": ["keep-alive", "Transfer-Encoding"],
"s_tag": "285873024335988|0^|^^",
"s_tid": "21410a7016573415536295456ef332",
"eagleeye-traceid": "21410a7016573415536295456ef332",
"s_v": "4.0.2.0",
"Content-Encoding": "gzip",
"P3P": "CP='CURa ADMa DEVa PSAo PSDo OUR BUS UNI PUR INT DEM STA PRE COM NAV OTC NOI DSP COR'",
"Date": "Sat, 09 Jul 2022 04:39:13 GMT",
"Access-Control-Max-Age": "3600",
"s_ucode": "Asia:CENTER",
"Access-Control-Allow-Methods": "POST, GET, OPTIONS, DELETE",
"Content-Type": "text/html;charset=UTF-8",
"s_status": "STATUS_NOT_EXISTED"
}
I pulled the cookie the same that you did:
let cookie = allHeaders['Set-Cookie'];
The issue with this is that it returns:
[
'hms_cid=80dcf576-a581-4d43-8302-1605fe36565c; Domain=.hms.zn; Expires=Sun, 09-Jul-2023 04:39:13 GMT; Path=/',
'hms_sid=112120422020a413958ddf33139b516b; Domain=.hms.zn; Path=/; HttpOnly',
'_tb_token_=e8eafb9bebe63; Domain=.hms.zn; Path=/; HttpOnly'
]
Using typeof I was able to determine this is an Object type.
let cookie = allHeaders['Set-Cookie'];
console.log(typeof(cookie));
object
Since this is an Object I enumerated the keys:
console.log(Object.keys(cookie));
[ '0', '1', '2' ]
Now I'm able to match the comma separated values with an object key. This means I can get only the cookie value with the info I need:
let cookie = allHeaders['Set-Cookie'][1];
Which outputs:
hms_sid=112120422020a413958ddf33139b516b; Domain=.hms.zn; Path=/; HttpOnly
After that I checked the type of the object again with typeof to find out it's a String so I used .split(";") string function to tokenize the string:
[
'hms_sid=112120422020a413958ddf33139b516b',
' Domain=.hms.zn',
' Path=/',
' HttpOnly'
]
we only care about the first token and we want to tokenize that again by =:
let sidString = tokens[0].split("=");
[ 'hms_sid', '112120422020a413958ddf33139b516b' ]
And there we have it, we can get the value with sidString[1]
