token refresh callback access token in Box using oauth2.0 using ruby - ruby

Question

I'm new to Box Api and ruby. I am trying trying refreshing token, but I'm not sure about what is token_refresh_callback in the below code
client = Boxr::Client.new('zX3UjFwNerOy5PSWc2WI8aJgMHtAjs8T',
refresh_token: 'dvfzfCQoIcRi7r4Yeuar7mZnaghGWexXlX89sBaRy1hS9e5wFroVVOEM6bs0DwPQ',
client_id: 'kplh54vfeagt6jmi4kddg4xdswwvrw8y',
client_secret: 'sOsm9ZZ8L8svwrn9FsdulLQVwDizKueU',
&token_refresh_callback)
Also, once my access token is expired, does this method revoke the token?
Thanks for the help!

Using the Access and Refresh Tokens
The access_token is the actual string needed to make API requests.Each access_token is valid for 1 hour.In order to get a new, valid token, you can use the accompanying refresh_token.Each refresh_token is valid for one use in 60 days.Every time you get a new access_token by using a refresh_token,
we reset your timer for the 60 day period and hand you a new refresh_token.
This means that as long as your users use your application once every 60 days, their login is valid forever.
In box_api_controller.rb file
def make_request
#Check access token expire or not.
check_access_token_expire = check_access_token_expire_dt
if check_access_token_expire.split("-")[0] == "access_token"
#Create client by passing Token
#box_client = Boxr::Client.new(check_access_token_expire.split("-")[1])
cookies[:token] = check_access_token_expire.split("-")[1]
else
if check_access_token_expire.split("-")[0] == "refresh_token"
#Call method
create_post_req_url("refresh_token","refresh_token",check_access_token_expire.split("-")[1])
else
# kick off authorization flow
parameters = "response_type=code&client_id=<your client id>&redirect_uri=<your application url>/handle_user_decision/&state=security_token"
url = "https://account.box.com/api/oauth2/authorize?#{parameters}"
redirect_to url
end
end
end
After authorized the client id, get code in response
def handle_user_decision
# kick off authorization flow
#Get authorization code
code_url = Rack::Utils.parse_query URI(request.original_url).query
code = code_url["code"]
#Call method
create_post_req_url("authorization_code","code", code)
end
Create Post Url
def create_post_req_url(grant_type,header, code)
#Set oauth2 url
uri = URI.parse("https://api.box.com//oauth2//token")
#Passing parameter
data = "grant_type=#{grant_type}&#{header}=#{code}&client_id=<your client id>&client_secret=<your client secret key>"
#Set header
headers = {"Content-Type" => "application/x-www-form-urlencoded"}
#Get http request
http = Net::HTTP.new(uri.host,uri.port)
http.use_ssl = true
http.verify_mode = OpenSSL::SSL::VERIFY_NONE
#Do post the URL
response = http.post(uri.path,data.to_s,headers)
#Check response
if response.code != "200"
flash[:alert] ="：#{response.code} #{JSON.parse(response.body)}"
else
#flash[:alert] ="#{response.body.to_json}"
parsed = JSON.parse(response.body) # returns a hash
token = parsed["access_token"]
cookies[:token] = nil
cookies[:token] = token
if grant_type == "authorization_code"
#Insert BOX access token details
user = "<your drive user name>"
insert_access_token(user, token, parsed["refresh_token"], Time.now)
else
if grant_type == "refresh_token"
#Update BOX access token
updt_access_token(user, token, code, parsed["refresh_token"], Time.now)
end
end
redirect_to box_api_index_path
end
end
Check access token expire or not
def check_access_token_expire_dt
#access_token_time = BoxApiAccessToken.getaccesstokentime
if !#access_token_time.blank?
#access_token_time.each do |token_details |
if token_details.access_token_dt != nil
if token_details.new_access_token_dt.to_datetime.new_offset(Rational(9, 24)).strftime('%Y/%m/%d %H:%M') < Time.now.to_datetime.new_offset(Rational(9, 24)).strftime('%Y/%m/%d %H:%M')
check_access_token_expire_dt = "refresh_token-#{token_details.refresh_access_token}"
return check_access_token_expire_dt
else
check_access_token_expire_dt = "access_token-#{token_details.access_token}"
return check_access_token_expire_dt
end
else
check_access_token_expire_dt = "new_token-req_new_token"
return check_access_token_expire_dt
end
end
else
check_access_token_expire_dt = "new_token-req_new_token"
return check_access_token_expire_dt
end
end
In Model
def insert_access_token(user,access_token,refresh_access_token,access_token_dt)
#box_access_token = BoxApiAccessToken.new(
:user => user,
:access_token => access_token,
:refresh_access_token => refresh_access_token,
:access_token_dt => access_token_dt)
#Save User Device Data
#box_access_token.save
end
#Update access_token,refresh_access_token,access_token_dt details in DB
def updt_access_token(user,access_token, refresh_access_token,new_refresh_access_token,access_token_dt)
##box_access_token_updt = BoxApiAccessToken.find_refresh_access_token(refresh_access_token)
#box_access_token_updt = BoxApiAccessToken.find_by_refresh_access_token(refresh_access_token)

I just want to want to request an access token and then after it expires refresh it using refresh token and cycle. How do you think i can do it?
