Chilkat .NET Downloads

Chilkat .NET Assemblies

Chilkat for .NET Core

Chilkat for Mono

// 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.

Chilkat.JsonObject json = new Chilkat.JsonObject();
bool success = json.LoadFile("qa_data/tokens/paypal.json");
if (success != true) {
    Debug.WriteLine("Failed to load access key json file.");
    return;
}

// Get the current date/time.
Chilkat.CkDateTime dateTime = new Chilkat.CkDateTime();
bool bLocalTime = false;
int dtNow = dateTime.GetAsUnixTime(bLocalTime);

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

// Find out how many seconds have elapsed.
int numSeconds = dtNow - dtCreate;

// Get the expires_in value from the JSON.
int expires_in = json.IntOf("expires_in");

Debug.WriteLine("token age (in seconds) = " + Convert.ToString(numSeconds));
Debug.WriteLine("expires_in = " + Convert.ToString(expires_in));

// If the token expired, or if it will expire in 5 minutes or less,
// get another token.
if (numSeconds < (expires_in - 300)) {
    Debug.WriteLine("The token is not yet expired.  No need to fetch another.");
    return;
}

Debug.WriteLine("Time to fetch a new access token...");

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