How to get Authorization Bearer Token with curl or other unix tool - linux

Question

I have a problem with getting Authorization Bearer Token value with unix tool like curl from site.
The problem is that I don't know how to get only this value 7FA733D2E75A962D1FED6D26989550BD. The value is different every time when i make a request (I mean it is not constant value).
I have necessary information for this request and when i try with some browser with cookie manager and put by hand cookie value it is work and get valid token.
Cookie value is:
mac=00%3A1A%3A79%3A40%3A07%3AFF
stb_lang=en
timezone=Europe%2FParis
Request URL is:
http://livegopanel.club:8080/portal.php?type=stb&action=handshake&token=&JsHttpRequest=1-xml
If I try to automate this job from linux console I am not able to get this token.
When I capture the tcp flow with wireshark get following information from process of getting valid token.
This is the request to site:
GET /portal.php?type=stb&action=handshake&token=&JsHttpRequest=1-xml HTTP/1.1
Accept: */*
User-Agent: Mozilla/5.0 (QtEmbedded; U; Linux; C) AppleWebKit/533.3 (KHTML, like Gecko) MAG200 stbapp ver: 4 rev: 2721 Mobile Safari/533.3

Cookie: mac=00%3A1A%3A79%3A40%3A07%3AFF; stb_lang=en; timezone=Europe%2FParis

And this is the response from site:

{"js":{"token":"7FA733D2E75A962D1FED6D26989550BD"}}
I try many variation with curl but not able to get the value. How to build the curl request or have is other way (script written on bash, perl, etc.) to do this?

If you have jq installed:
curl -s http://livegopanel.club:8080/portal.php\?type\=stb\&action\=handshake\&token\=\&JsHttpRequest\=1-xml | jq -r '.js.token'
jq is a swiss army knife for JSON, if you're going to be working with JSON on the command line, I recommend getting acquainted with jq. You can use https://jqplay.org to test your jq filters live.
Otherwise using sed:
curl -s http://livegopanel.club:8080/portal.php\?type\=stb\&action\=handshake\&token\=\&JsHttpRequest\=1-xml | sed 's/.*token":"\(.*\)".*/\1/g'
