It strives to +directly map the requests and responses of those specifications, while following +the idiomatic style of the implementation language.

Just run: + + pod try AppAuth + +Follow the instructions in [Example/README.md](Example/README.md) to configure +with your own OAuth client (you need to update 3 configuration points with your +client info to try the demo). + +## Setup + +If you use [CocoaPods](https://guides.cocoapods.org/using/getting-started.html), +simply add: + + pod 'AppAuth' + +To your `Podfile` and run `pod install`. Otherwise, add `AppAuth.xcodeproj` +into your workspace. + +## Auth Flow + +AppAuth supports both manual interaction with the Authorization Server +where you need to perform your own token exchanges, as well as convenience +methods that perform some of this logic for you. This example uses the +convenience method which returns either an `OIDAuthState` object, or an error. + +`OIDAuthState` is a class that keeps track of the authorization and token +requests and responses, and provides a convenience method to call an API with +fresh tokens. This is the only object that you need to serialize to retain the +authorization state of the session. + +### Configuration + +You can configure AppAuth by specifying the endpoints directly: + +```objc +NSURL *authorizationEndpoint = + [NSURL URLWithString:@"https://accounts.google.com/o/oauth2/v2/auth"]; +NSURL *tokenEndpoint = + [NSURL URLWithString:@"https://www.googleapis.com/oauth2/v4/token"]; + +OIDServiceConfiguration *configuration = + [[OIDServiceConfiguration alloc] + initWithAuthorizationEndpoint:authorizationEndpoint + tokenEndpoint:tokenEndpoint]; + +// perform the auth request... +``` + +Or through discovery: + +```objc +NSURL *issuer = [NSURL URLWithString:@"https://accounts.google.com"]; + +[OIDAuthorizationService discoverServiceConfigurationForIssuer:issuer + completion:^(OIDServiceConfiguration *_Nullable configuration, + NSError *_Nullable error) { + + if (!configuration) { + NSLog(@"Error retrieving discovery document: %@", + [error localizedDescription]); + return; + } + + // perform the auth request... +}]; +``` + +### Authorizing – iOS + +First you need to have a property in your AppDelegate to hold the session, in +order to continue the authorization flow from the redirect. + +```objc +// property of the app's AppDelegate +@property(nonatomic, strong, nullable) + id currentAuthorizationFlow; +``` + +And your main class, a property to store the auth state: + +```objc +// property of the containing class +@property(nonatomic, strong, nullable) OIDAuthState *authState; +``` + +Then, initiate the authorization request. By using the +`authStateByPresentingAuthorizationRequest` convenience method, the token +exchange will be performed automatically, and everything will be protected with +PKCE (if the server supports it). AppAuth also allows you to perform these +requests manually. See the `authNoCodeExchange` method in the included Example +app for a demonstration. + +```objc +// builds authentication request +OIDAuthorizationRequest *request = + [[OIDAuthorizationRequest alloc] initWithConfiguration:configuration + clientId:kClientID + scopes:@[OIDScopeOpenID, + OIDScopeProfile] + redirectURL:KRedirectURI + responseType:OIDResponseTypeCode + additionalParameters:nil]; + +// performs authentication request +AppDelegate *appDelegate = + (AppDelegate *)[UIApplication sharedApplication].delegate; +appDelegate.currentAuthorizationFlow = + [OIDAuthState authStateByPresentingAuthorizationRequest:request + presentingViewController:self + callback:^(OIDAuthState *_Nullable authState, + NSError *_Nullable error) { + if (authState) { + NSLog(@"Got authorization tokens. Access token: %@", + authState.lastTokenResponse.accessToken); + [self setAuthState:authState]; + } else { + NSLog(@"Authorization error: %@", [error localizedDescription]); + [self setAuthState:nil]; + } +}]; +``` + +*Handling the Redirect* + +The authorization response URL is returned to the app via the iOS openURL +app delegate method, so you need to pipe this through to the current +authorization session (created in the previous session). + +```objc +- (BOOL)application:(UIApplication *)app + openURL:(NSURL *)url + options:(NSDictionary *)options { + // Sends the URL to the current authorization flow (if any) which will + // process it if it relates to an authorization response. + if ([_currentAuthorizationFlow resumeAuthorizationFlowWithURL:url]) { + _currentAuthorizationFlow = nil; + return YES; + } + + // Your additional URL handling (if any) goes here. + + return NO; +} +``` + +### Authorizing – MacOS + +On macOS, the most popular way to get the authorization response redirect is to +start a local HTTP server on the loopback interface (limited to incoming +requests from the user's machine only). When the authorization is complete, the +user is redirected to that local server, and the authorization response can be +processed by the app. AppAuth takes care of managing the local HTTP server +lifecycle for you. + +> #### :bulb: Alternative: Custom URI Schemes +> Custom URI schemes are also supported on macOS, but some browsers display +> an interstitial which reduces the usability. For an example on using custom +> URI schemes with macOS, See `Example-Mac`. + +To receive the authorization response using a local HTTP server, first you need +to have an instance variable in your main class to retain the HTTP redirect +handler. + +```objc +OIDRedirectHTTPHandler *_redirectHTTPHandler; +``` + +Then, as the port used by the local HTTP server varies, you need to start it +before building the authorization request in order to get the exact redirect +URI to use. + +```objc +static NSString *const kSuccessURLString = + @"http://openid.github.io/AppAuth-iOS/redirect/"; +NSURL *successURL = [NSURL URLWithString:kSuccessURLString]; + +// Starts a loopback HTTP redirect listener to receive the code. This needs to be started first, +// as the exact redirect URI (including port) must be passed in the authorization request. +_redirectHTTPHandler = [[OIDRedirectHTTPHandler alloc] initWithSuccessURL:successURL]; +NSURL *redirectURI = [_redirectHTTPHandler startHTTPListener:nil]; +``` + +Then, initiate the authorization request. By using the +`authStateByPresentingAuthorizationRequest` convenience method, the token +exchange will be performed automatically, and everything will be protected with +PKCE (if the server supports it). By assigning the return value to the +`OIDRedirectHTTPHandler`'s `currentAuthorizationFlow`, the authorization will +continue automatically once the user makes their choice. + +```objc +// builds authentication request +OIDAuthorizationRequest *request = + [[OIDAuthorizationRequest alloc] initWithConfiguration:configuration + clientId:kClientID + clientSecret:kClientSecret + scopes:@[ OIDScopeOpenID ] + redirectURL:redirectURI + responseType:OIDResponseTypeCode + additionalParameters:nil]; +// performs authentication request +__weak __typeof(self) weakSelf = self; +_redirectHTTPHandler.currentAuthorizationFlow = + [OIDAuthState authStateByPresentingAuthorizationRequest:request + callback:^(OIDAuthState *_Nullable authState, + NSError *_Nullable error) { + // Brings this app to the foreground. + [[NSRunningApplication currentApplication] + activateWithOptions:(NSApplicationActivateAllWindows | + NSApplicationActivateIgnoringOtherApps)]; + + // Processes the authorization response. + if (authState) { + NSLog(@"Got authorization tokens. Access token: %@", + authState.lastTokenResponse.accessToken); + } else { + NSLog(@"Authorization error: %@", error.localizedDescription); + } + [weakSelf setAuthState:authState]; +}]; +``` + +### Making API Calls + +AppAuth gives you the raw token information, if you need it. However we +recommend that users of the `OIDAuthState` convenience wrapper use the provided +`performActionWithFreshTokens:` method to perform their API calls to avoid +needing to worry about token freshness. + +```objc +[_authState performActionWithFreshTokens:^(NSString *_Nonnull accessToken, + NSString *_Nonnull idToken, + NSError *_Nullable error) { + if (error) { + NSLog(@"Error fetching fresh tokens: %@", [error localizedDescription]); + return; + } + + // perform your API request using the tokens +}]; +``` + +## API Documentation + +Browse the [API documentation] +(http://openid.github.io/AppAuth-iOS/docs/latest/annotated.html). + +## Included Samples + +You can try out the iOS sample included in the source distribution by opening +`Example/Example.xcworkspace`.

The key differentiator is +the use of the user's default browser for the authorization, which is more +secure, more usable (the user's session can be reused) and follows modern OAuth +[best practices for native apps](https://tools.ietf.org/html/draft-ietf-oauth-native-apps). +Compatibility methods for GTMOAuth2 are offered allowing you to migrate +from GTMOAuth2 to GTMAppAuth preserving previously serialized authorizations +(so users shouldn't need to re-authenticate). + +## Setup + +If you use [CocoaPods](https://guides.cocoapods.org/using/getting-started.html), +simply add: + + pod 'GTMAppAuth' + +To your `Podfile` and run `pod install`. + +## Usage + +### Configuration + +To configure GTMAppAuth with the OAuth endpoints for Google, you can use the +convenience method: + +```objc +OIDServiceConfiguration *configuration = + [GTMAppAuthFetcherAuthorization configurationForGoogle]; +``` + +Alternatively, you can configure GTMAppAuth by specifying the endpoints +directly: + +```objc +NSURL *authorizationEndpoint = + [NSURL URLWithString:@"https://accounts.google.com/o/oauth2/v2/auth"]; +NSURL *tokenEndpoint = + [NSURL URLWithString:@"https://www.googleapis.com/oauth2/v4/token"]; + +OIDServiceConfiguration *configuration = + [[OIDServiceConfiguration alloc] + initWithAuthorizationEndpoint:authorizationEndpoint + tokenEndpoint:tokenEndpoint]; + +// perform the auth request... +``` + +Or through discovery: + +```objc +NSURL *issuer = [NSURL URLWithString:@"https://accounts.google.com"]; + +[OIDAuthorizationService discoverServiceConfigurationForIssuer:issuer + completion:^(OIDServiceConfiguration *_Nullable configuration, + NSError *_Nullable error) { + if (!configuration) { + NSLog(@"Error retrieving discovery document: %@", + [error localizedDescription]); + return; + } + + // perform the auth request... +}]; +``` + +### Authorizing + +First, you need to have a way for your UIApplicationDelegate to continue the +authorization flow session from the incoming redirect URI. Typically you could +store the in-progress OIDAuthorizationFlowSession instance in a property: + +```objc +// property of the app's UIApplicationDelegate +@property(nonatomic, nullable) + id currentAuthorizationFlow; +``` + +And in a location accessible by all controllers that need authorization, a +property to store the authorization state: + +```objc +// property of the containing class +@property(nonatomic, nullable) GTMAppAuthFetcherAuthorization *authorization; +``` + +Then, initiate the authorization request. By using the +`authStateByPresentingAuthorizationRequest` method, the OAuth token +exchange will be performed automatically, and everything will be protected with +PKCE (if the server supports it). + +```objc +// builds authentication request +OIDAuthorizationRequest *request = + [[OIDAuthorizationRequest alloc] initWithConfiguration:configuration + clientId:kClientID + clientSecret:kClientSecret + scopes:@[OIDScopeOpenID, OIDScopeProfile] + redirectURL:redirectURI + responseType:OIDResponseTypeCode + additionalParameters:nil]; +// performs authentication request +self.appDelegate.currentAuthorizationFlow = + [OIDAuthState authStateByPresentingAuthorizationRequest:request + callback:^(OIDAuthState *_Nullable authState, + NSError *_Nullable error) { + if (authState) { + // Creates the GTMAppAuthFetcherAuthorization from the OIDAuthState. + GTMAppAuthFetcherAuthorization *authorization = + [[GTMAppAuthFetcherAuthorization alloc] initWithAuthState:authState]; + + self.authorization = authorization; + NSLog(@"Got authorization tokens.

In the +folder run `pod install`, then open the `xcworkspace` file. + +Be sure to follow the instructions in +[Example-iOS/README.md](Example-iOS/README.md) or +[Example-macOS/README.md](Example-macOS/README.md) to configure your own OAuth +client ID for use with the example. + +## Differences with GTMOAuth2 + +### Authorization Method + +GTMAppAuth uses the browser to present the authorization request, while +GTMOAuth2 uses an embedded web-view. Migrating to GTMAppAuth will require you +to change how you authorize the user. Follow the instructions above to get the +authorization. You can then create a `GTMAppAuthFetcherAuthorization` object +with the `initWithAuthState:authState` initializer. + +Once you have the `GTMAppAuthFetcherAuthorization` you can continue to make REST +calls as before. + +### Error Handling + +GTMAppAuth's error handling is also different. There are no notifications, +instead you need to inspect NSError in the callback. If the error domain is +`OIDOAuthTokenErrorDomain`, it indicates an authorization error, you should +clear your authorization state and consider prompting the user to authorize +again. Other errors are generally considered transient, meaning that you should +retry the request after a delay. + +### Serialization + +The serialization format is different between GTMOAuth2 and GTMAppAuth, though +we have methods to help you migrate from one to the other without losing any +data. + +## Migrating from GTMOAuth2 + +### OAuth Client Registration + +Typically, GTMOAuth2 clients are registered with Google as type "Other". This is +correct for macOS, but on iOS clients should be registered with the type "iOS". + +If you're migrating an iOS client, in the *same project as your existing client*, +[register a new iOS client](https://console.developers.google.com/apis/credentials?project=_) +to be used with GTMAppAuth. + +### Changing your Authorization Flows + +Both GTMOAuth2 and GTMAppAuth support the `GTMFetcherAuthorizationProtocol` +allowing you to use the authorization with the session fetcher. Where you +previously had a property like `GTMOAuth2Authentication *authorization` change the +type to reference the protocol instead, i.e.: +`id authorization`. This allows you to switch +the authorization implementation under the hood to GTMAppAuth. + +Then, follow the instructions above to replace authorization request +(where you ask the user to grant access) with the GTMAppAuth approach. If you +created a new OAuth client, use that for these requests. + +### Serialization & Migrating Existing Grants + +GTMAppAuth has a different way to serialize the authorization. Change how you +serialize your `authorization` object using the new methods, e.g.: + +```objc +// Serialize to Keychain +[GTMAppAuthFetcherAuthorization saveAuthorization:(GTMAppAuthFetcherAuthorization *)authorization + toKeychainForName:kNewKeychainName]; +``` + +Be sure to use a *new* name for the keychain. Don't reuse your existing one! + +For deserializing, we can preserve all existing grants (so users who authorized +your app in GTMOAuth2 don't have to authorize it again). Remember that when +deserializing the old data you need to use your *old* keychain name, and +the old client id and client secret (if those changed). Pay particular care to +use the old details when deserializing the GTMOAuth2 keychain, and the new +details for all other GTMAppAuth calls. + +Keychain migration example: + +```objc +// Attempt to deserialize from Keychain in GTMAppAuth format. +id authorization = + [GTMAppAuthFetcherAuthorization authorizationFromKeychainForName:kNewKeychainName]; + +// If no data found in the new format, try to deserialize data from GTMOAuth2 +if (!authorization) { + // Tries to load the data serialized by GTMOAuth2 using old keychain name. + // If you created a new client id, be sure to use the *previous* client id and secret here. + authorization = + [GTMOAuth2KeychainCompatibility authForGoogleFromKeychainForName:kPreviousKeychainName + clientID:kPreviousClientID + clientSecret:kPreviousClientSecret]; + if (authorization) { + // Remove previously stored GTMOAuth2-formatted data. + [GTMOAuth2KeychainCompatibility removeAuthFromKeychainForName:kPreviousKeychainName]; + // Serialize to Keychain in GTMAppAuth format. + [GTMAppAuthFetcherAuthorization saveAuthorization:(GTMAppAuthFetcherAuthorization *)authorization + toKeychainForName:kNewKeychainName]; + } +} +``` diff --git a/Paco-iOS/Pods/GTMAppAuth/Source/GTMAppAuth.h b/Paco-iOS/Pods/GTMAppAuth/Source/GTMAppAuth.h new file mode 100644 index 000000000..644349ebb --- /dev/null +++ b/Paco-iOS/Pods/GTMAppAuth/Source/GTMAppAuth.h @@ -0,0 +1,30 @@ +/*! @file GTMAppAuth.h + @brief GTMAppAuth SDK + @copyright + Copyright 2016 Google Inc.

The user may set a retry selector to -// customize the type of errors which will be retried. -// -// Retries are done in an exponential-backoff fashion (that is, after 1 second, -// 2, 4, 8, and so on.) -// -// Enabling automatic retries looks like this: -// [myFetcher setRetryEnabled:YES]; -// -// With retries enabled, the success or failure callbacks are called only -// when no more retries will be attempted.
