(Swift) Auth0 Server-to-Server Access Token (Client Credentials flow)Demonstrates how to obtain an Auth0 access token using client credentials (client_id and client_secret). This is just a matter of duplicating this CURL command: curl --request POST --url 'https://chilkat.auth0.com/oauth/token' \ --header 'content-type: application/json' \ --data '{"grant_type":"client_credentials","client_id": "xxxx","client_secret": "xxxx","audience": "https://api.example.com/geocoding/v1/"}' Note: This example requires Chilkat v11.0.0 or greater.
func chilkatTest() { var success: Bool = false // This example assumes the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. // We want to duplicate this curl command: // // curl --request POST // --url 'https://chilkat.auth0.com/oauth/token' \ // --header 'content-type: application/json' \ // --data '{"grant_type":"client_credentials","client_id": "my_client_id","client_secret": "my_client_secret","audience": "https://api.example.com/geocoding/v1/"}' // Build the JSON body of the request. let json = CkoJsonObject()! json.update("grant_type", value: "client_credentials") json.update("client_id", value: "AUTH0-CLIENT-ID") json.update("client_secret", value: "AUTH0-CLIENT-SECRET") json.update("audience", value: "https://api.example.com/geocoding/v1/") // IMPORTANT: You would use your own url. You would not use "chilkat.auth0.com". // Instead you would use "your_name.auth0.com" let http = CkoHttp()! let resp = CkoHttpResponse()! success = http.httpJson("POST", url: "https://chilkat.auth0.com/oauth/token", json: json, contentType: "application/json", response: resp) if success == false { print("\(http.lastErrorText!)") return } // A 200 response status code indicates success. In the success case, the response body // contains the JSON access token, such as: // { // "access_token": "eyJz93a...k4laUWw", // "token_type":"Bearer", // "expires_in":86400 // } // print("response status code = \(resp.statusCode.intValue)") // The repsonse is JSON if successful and also JSON for errors. let jsonResp = CkoJsonObject()! jsonResp.emitCompact = false jsonResp.load(resp.bodyStr) if resp.statusCode.intValue != 200 { // The response body contains error information in JSON format. print("\(jsonResp.emit()!)") // An example of an error response: // { // "error": "access_denied", // "error_description": "Client is not authorized to access \"https://api.example.com/geocoding/v1/\". You might probably want to create a \"client-grant\" associated to this API. See: https://auth0.com/docs/api/v2#!/Client_Grants/post_client_grants" // } return } print("Success!") print("\(jsonResp.emit()!)") // A successful JSON response body looks like this: // { // "access_token": "eyJz93a...k4laUWw", // "token_type":"Bearer", // "expires_in":86400 // } } |
