(.NET Core C#) Wish for Merchants -- Get OAuth2 Access Token for Desktop AppDemonstrates how to get a Wish for Merchants OAuth2 access token from a desktop application or script.
// This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. // This example is for desktop applicatons (it is not for code that runs on a web server). // You'll need to add a line (or a few lines of code) to popup a web browser that navigates to a URL. // This is explained in the comments below. // This is the way to initially obtain the OAuth2 access token. Afterwards it can be // repeatedly refreshed without user interaction, as shown in this example: Refresh Wish OAuth2 Access Token. Chilkat.OAuth2 oauth2 = new Chilkat.OAuth2(); bool success; // Wish OAuth2 does not allow a localhost callback URI such as "http://localhost:<portNumber>/" // For a desktop app, you must provide a script on your web server to redirect to "http://localhost/<portNumber>" // It can be written in C#, PHP, or whatever desired. It must include the query string in the redirection. // For example, in PHP your script would look like this: // <?php // header( 'Location: http://localhost:3017?' . $_SERVER['QUERY_STRING'] ); // ?> oauth2.AppCallbackUrl = "https://yourwebserver.com/OAuth2.php"; oauth2.ListenPort = 3017; oauth2.AuthorizationEndpoint = "https://merchant.wish.com/v3/oauth/authorize"; oauth2.TokenEndpoint = "https://merchant.wish.com/api/v3/oauth/access_token"; oauth2.UncommonOptions = "EXCHANGE_CODE_FOR_TOKEN_USING_GET"; // Replace these with actual values. oauth2.ClientId = "WISH-CLIENT-ID"; oauth2.ClientSecret = "WISH-CLIENT-SECRET"; oauth2.Scope = ""; // Begin the OAuth2 three-legged flow. This returns a URL that should be loaded in a browser. string url = oauth2.StartAuth(); if (oauth2.LastMethodSuccess != true) { Debug.WriteLine(oauth2.LastErrorText); return; } Debug.WriteLine("url = " + url); // 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 Wish 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 60 seconds. int numMsWaited = 0; while ((numMsWaited < 60000) && (oauth2.AuthFlowState < 3)) { oauth2.SleepMs(100); numMsWaited = numMsWaited + 100; } // If there was no response from the browser within 60 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(); Debug.WriteLine("No response from the browser!"); return; } // 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) { Debug.WriteLine("OAuth2 failed to complete."); Debug.WriteLine(oauth2.FailureInfo); return; } if (oauth2.AuthFlowState == 4) { Debug.WriteLine("OAuth2 authorization was denied."); Debug.WriteLine(oauth2.AccessTokenResponse); return; } if (oauth2.AuthFlowState != 3) { Debug.WriteLine("Unexpected AuthFlowState:" + Convert.ToString(oauth2.AuthFlowState)); return; } // Save the full JSON access token response to a file. Chilkat.StringBuilder sbJson = new Chilkat.StringBuilder(); sbJson.Append(oauth2.AccessTokenResponse); sbJson.WriteFile("qa_data/tokens/wish.json","utf-8",false); // The full JSON received looks like this: // { // "message": "", // "code": 0, // "data": { // "access_token": "15af1c191c1243b029bc1660b5c08ce7", // "scopes": [ // "epc:read", // "epc:write", // "fbs:read", // "fbs:write", // "fbw:read", // "fbw:write", // "infractions:read", // "infractions:write", // "insurance:read", // "insurance:write", // "loans:read", // "loans:write", // "merchant:read", // "merchant:write", // "notifications:read", // "notifications:write", // "orders:read", // "orders:write", // "payments:read", // "payments:write", // "penalties:read", // "penalties:write", // "product_boost:read", // "product_boost:write", // "products:read", // "products:write", // "ratings:read", // "ratings:write", // "returns:read", // "returns:write", // "tickets:read", // "tickets:write" // ], // "merchant_id": "5eb3f605178f5be2c784fa02", // "expiry_time": "2020-12-17T16:55:09.594+00:00", // "refresh_token": "55a38e44df674a1e859891624b2c4c23" // } // } Debug.WriteLine("OAuth2 authorization granted!"); Debug.WriteLine("Access Token = " + oauth2.AccessToken); |
