[iOS] SwiftyOAuth：极为小巧、易用的 OAuth 授权类库

SwiftyOAuthis a small OAuth library with a built-in set of providers and a nice API to add your owns.

let github: Provider = .GitHub(clientID: "***", clientSecret: "***", redirectURL: "foo://callback")  github.authorize { result in     print(result) // Success(Token(accessToken: "abc123", tokenType: "bearer", scope: "")) }

Usage

Provider

Initialize a provider with the custom URL scheme that you defined:

let provider = Provider(     clientID: "***",     clientSecret: "***",     authorizeURL: "https://example.com/authorize",     tokenURL: "https://example.com/authorize/token",     redirectURL: "foo://callback" )

Alternatively, you can use a built-in provider:

let github = .GitHub(     clientID: "***",     clientSecret: "***",     redirectURL: "foo://callback" )

Optionally set the state and scope properties:

github.state = "asdfjkl;" // An random string used to protect against CSRF attacks. github.scope = "public_repo"

Define additional parameters for the authorization request or the token request with additionalParamsForAuthorization and additionalParamsForTokenRequest respectively:

github.additionalParamsForAuthorization["allow_signup"] = false

Handle the incoming requests in your AppDelegate :

func application(app: UIApplication, openURL url: NSURL, options: [String : AnyObject]) -> Bool {     github.handleURL(url, options: options)      return true }

Finally, ask for authorization. SwiftyOAuth will either present a SFSafariViewController (iOS 9) or open mobile safari.

github.authorize { (result: Result<Token, Error>) -> Void in     switch result {     case .Success(let token):         print(token)     case .Failure(let error):         print(error)     }  }

Token

The access_token , token_type and scope are available as Token properties:

token.accessToken // abc123 token.tokenType // bearer token.scope // public_repo

Additionally, you can access all the response data via the dictionary property:

token.dictionary // ["access_token": "abc123, "token_type": "bearer", "scope": "public_repo"]

Error

Erroris a enum that conforms to the ErrorType protocol.

• Cancel The user cancelled the authorization process by closing the web browser window.

• ApplicationSuspended The OAuth application you set up has been suspended.

• RedirectURIMismatch The provided redirectURL that doesn't match what you've registered with your application.

• AccessDenied The user rejects access to your application.

• IncorrectClientCredentials The clientID and or clientSecret you passed are incorrect.

• BadVerificationCode The verification code you passed is incorrect, expired, or doesn't match what you received in the first request for authorization.

• Other The application emitted a response in the form of {"error": "xxx", "error_description": "yyy"} but SwiftyOAuth doesn't have a enum for it. The data is available in the associated values.

• Unknown The application emitted a response that is neither in the form of a success one ( {"access_token": "xxx"...} ) nor in the form of a failure one ( {"error": "xxx"...} ). The data is available in the associated value.

• NSError An error triggered when making network requests or parsing JSON. The data is available in the associated value.

Providers

• GitHub -code, doc
• Dribbble -code, doc
• More to come...

Roadmap

• Store the token in the Keychain
• Support for Client Flow
• Refresh token (when available)
• More providers
