(PHP ActiveX) OAuth2 using a SOCKS Proxy (for a Desktop Application)Demonstrates how to send OAuth2 communications through a SOCKS proxy for a desktop application. The technique is the same for all OAuth2 applications. This one happens to demonstrate for Microsoft Graph.
<?php // This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. // To use a SOCKS proxy with OAuth2, create a Chilkat socket object and specify the details for the // SOCKS proxy server (SOCKS4 or SOCKS5). // For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Socket') $socket = new COM("Chilkat.Socket"); // Use your SOCKS proxy server domain or IP address. $socket->SocksHostname = 'mysocksproxyserver.com'; // Change this to the listening port of your SOCKS proxy server (if necessary) $socket->SocksPort = 1080; $socket->SocksUsername = 'myProxyLogin'; $socket->SocksPassword = 'myProxyPassword'; // Set the SOCKS version to 4 or 5 based on the version // of the SOCKS proxy server: $socket->SocksVersion = 5; // Note: SOCKS4 servers only support usernames without passwords. // SOCKS5 servers support full login/password authentication. // For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.OAuth2') $oauth2 = new COM("Chilkat.OAuth2"); // We don't need to connect the socket beforehand. // Just tell oauth2 to use the socket which has the SOCKS proxy properties. $success = $oauth2->UseConnection($socket); // This should be the port in the localhost callback URL for your app. // The callback URL would look like "http://localhost:3017/" if the port number is 3017. $oauth2->ListenPort = 3017; $oauth2->AuthorizationEndpoint = 'https://login.microsoftonline.com/common/oauth2/v2.0/authorize'; $oauth2->TokenEndpoint = 'https://login.microsoftonline.com/common/oauth2/v2.0/token'; // Replace these with actual values. $oauth2->ClientId = 'MICROSOFT-GRAPH-CLIENT-ID'; // This is your app password: $oauth2->ClientSecret = 'MICROSOFT-GRAPH-CLIENT-SECRET'; $oauth2->CodeChallenge = 0; // Provide a SPACE separated list of scopes. // See https://developer.microsoft.com/en-us/graph/docs/authorization/permission_scopes // Important: To get a refresh token in the final response, you have to ask for "offline_access" scope $oauth2->Scope = 'openid profile offline_access user.readwrite mail.readwrite mail.send files.readwrite'; // Begin the OAuth2 three-legged flow. This returns a URL that should be loaded in a browser. $url = $oauth2->startAuth(); if ($oauth2->LastMethodSuccess != 1) { print $oauth2->LastErrorText . "\n"; exit; } // At this point, your application should load the URL in a browser. // For example, // in C#: System.Diagnostics.Process.Start(url); // in Java: Desktop.getDesktop().browse(new URI(url)); // in VBScript: Set wsh=WScript.CreateObject("WScript.Shell") // wsh.Run url // in Xojo: ShowURL(url) (see http://docs.xojo.com/index.php/ShowURL) // in Dataflex: Runprogram Background "c:\Program Files\Internet Explorer\iexplore.exe" sUrl // The Microsoft account owner would interactively accept or deny the authorization request. // Add the code to load the url in a web browser here... // Add the code to load the url in a web browser here... // Add the code to load the url in a web browser here... // Now wait for the authorization. // We'll wait for a max of 30 seconds. $numMsWaited = 0; while (($numMsWaited < 30000) and ($oauth2->AuthFlowState < 3)) { $oauth2->SleepMs(100); $numMsWaited = $numMsWaited + 100; } // If there was no response from the browser within 30 seconds, then // the AuthFlowState will be equal to 1 or 2. // 1: Waiting for Redirect. The OAuth2 background thread is waiting to receive the redirect HTTP request from the browser. // 2: Waiting for Final Response. The OAuth2 background thread is waiting for the final access token response. // In that case, cancel the background task started in the call to StartAuth. if ($oauth2->AuthFlowState < 3) { $oauth2->Cancel(); print 'No response from the browser!' . "\n"; exit; } // Check the AuthFlowState to see if authorization was granted, denied, or if some error occurred // The possible AuthFlowState values are: // 3: Completed with Success. The OAuth2 flow has completed, the background thread exited, and the successful JSON response is available in AccessTokenResponse property. // 4: Completed with Access Denied. The OAuth2 flow has completed, the background thread exited, and the error JSON is available in AccessTokenResponse property. // 5: Failed Prior to Completion. The OAuth2 flow failed to complete, the background thread exited, and the error information is available in the FailureInfo property. if ($oauth2->AuthFlowState == 5) { print 'OAuth2 failed to complete.' . "\n"; print $oauth2->FailureInfo . "\n"; exit; } if ($oauth2->AuthFlowState == 4) { print 'OAuth2 authorization was denied.' . "\n"; print $oauth2->AccessTokenResponse . "\n"; exit; } if ($oauth2->AuthFlowState != 3) { print 'Unexpected AuthFlowState:' . $oauth2->AuthFlowState . "\n"; exit; } print 'OAuth2 authorization granted!' . "\n"; print 'Access Token = ' . $oauth2->AccessToken .
