(PHP Extension) GeoOp OAuth2 Authorisation Code Grant (Public App)Demonstrates how to get an access token for a GeoOp Third-Party Public Application using the Authorisation Code Grant flow. Note: This example requires Chilkat v9.5.0.63 or greater.
<?php // The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number. // For example, if using Chilkat v9.5.0.48, then include as shown here: include("chilkat_9_5_0.php"); // Note: This example requires Chilkat v9.5.0.63 or greater. // It requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. $oauth2 = new CkOAuth2(); // This should match the Site URL configured for your GeoOp Application, such as "http://localhost:3017/" $oauth2->put_ListenPort(3017); $oauth2->put_AuthorizationEndpoint('https://login.geoop.com/oauth2/code'); $oauth2->put_TokenEndpoint('https://login.geoop.com/oauth2/token'); // Replace the client ID with an actual value. $oauth2->put_ClientId('GEOOP-CLIENT-ID'); // The ClientSecret should remain empty for a GeoOp public application $oauth2->put_ClientSecret(''); // We need a few special settings for GeoOp $oauth2->put_Scope('default'); $oauth2->put_CodeChallenge(false); // Setting LocalHost equal to "none" prevents the "redirect_uri" query param from being sent in the initial HTTP request. // Note: The GeoOp Application should still have a redirect URL specified as "http://localhost:3017/", where the port // number matches the ListenPort above. $oauth2->put_LocalHost('none'); // Begin the OAuth2 three-legged flow.

The OAuth2 flow has completed, the background thread exited, and the successful JSON response is available in AccessTokenResponse property. // 4: Completed with Access Denied. The OAuth2 flow has completed, the background thread exited, and the error JSON is available in AccessTokenResponse property. // 5: Failed Prior to Completion.
