# Note: Requires Chilkat v9.5.0.64 or greater.

# This requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

# In the example linked here: PayPal OAuth2 Token,
# we fetched a PayPal access token and saved it to a JSON file.
# We also recorded the current date/time.
# Load this JSON file and compare the current date/time with the fetch date/time
# and the "expires_in" value to see if the token is expired.

json = chilkat.CkJsonObject()
success = json.LoadFile("qa_data/tokens/paypal.json")
if (success != True):
    print("Failed to load access key json file.")
    sys.exit()

# Get the current date/time.
dateTime = chilkat.CkDateTime()
bLocalTime = False
dtNow = dateTime.GetAsUnixTime(bLocalTime)

# Get the access token create date/time
dtCreate = json.IntOf("tokenCreateTimeUtc")

# Find out how many seconds have elapsed.
numSeconds = dtNow - dtCreate

# Get the expires_in value from the JSON.
expires_in = json.IntOf("expires_in")

print("token age (in seconds) = " + str(numSeconds))
print("expires_in = " + str(expires_in))

# If the token expired, or if it will expire in 5 minutes or less,
# get another token.
if (numSeconds < (expires_in - 300)):
    print("The token is not yet expired.  No need to fetch another.")
    sys.exit()

print("Time to fetch a new access token...")

# Get another token..
# See the example at Get PayPal OAuth2 Token
# to get another token..
