p2 / oauth2 Goto Github PK

How do I most easily implement so that I do not need to log in every time? I assume the framework supports so I can use hasUnexpiredAccessToken() to first check if accesstoken is ok, then if not, try to use refresh token to get a new unexpired access token.

What's the best way to do this?

Also do you recommend any way of storing the tokens on the device so they don't get cleared when closing the app?

Performed a OAuth2CodeGrant operation with Facebook settings:

let settings = [
            "client_id": "xxxx",
            "client_secret": "xxxx",
            "authorize_uri": "https://graph.facebook.com/oauth/authorize",
            "token_uri": "https://graph.facebook.com/oauth/access_token",
            "scope": "email",
            "redirect_uris": ["domain name"],
        ]

And got the error Authorization went wrong: The operation couldn’t be completed. (Cocoa error 3840.) after the JSONObjectWithData method has been called:

let json = NSJSONSerialization.JSONObjectWithData(data, options: nil, error: &finalError) as? NSDictionary

Hi, I'm having trouble adding your library to my project. The documentation states "the built framework can be used on ... iOS 8 and later." What specifically do I add tp my project?

I've downloaded the code and opened it Xcode and I see a folder named Products with two references to Oauth2.framework, both in red, so no files found. Do I need to build something?

I've also looked at your sample app in Xcode, and I see there a reference to OAuth2.xcodeproj, but as a folder. If I add that file to my project, it stays a file. Even if I drag the folder from the sample app it turns into a file. In either case, when I navigate to Build Phases > Target Dependencies I don't see Oauth2 as it is in the sample app.

I'm relatively new to iOS/Xcode, so hopefully I'm not missing something obvious. I've googled to no avail.

Thanks!

I have implement this library,
Well I must appreciate the Docs

Performed a OAuth2CodeGrant operation with Google+ settings:

let settings = [
    "client_id": xxxx,
    "authorize_uri": "https://accounts.google.com/o/oauth2/auth",
    "token_uri": "https://accounts.google.com/o/oauth2/token",
    "scope": "https://www.googleapis.com/auth/plus.login https://www.googleapis.com/auth/userinfo.email",
    "redirect_uris": ["urn:ietf:wg:oauth:2.0:oob:auto"],
]

The authentication succeeded by the OAuth2WebView was not dismissed automatically.

I put a breakpoint in shouldStartLoadWithRequest method of the OAuth2WebViewController and noticed that request.URL.scheme does not equal to interceptComponents?.scheme and the same for request.URL.host and interceptComponents?.host. So onInterceptcallback is never called.

When i use the smart and new SFSafariViewController i get and error: "Cannot Open Page - Safari cannot open the because the address is invalid" and when i press OK the site i blank.

Is there something i need to implement ??

CocoaPods recently added support for Swift. Could we add an Oauth2.podspec file to make this great lib available through CocoaPods?

Hi,

Im trying to get your code working but run into the error mentioned in the title. Environment is XCode 7 (new beta)/Swift 2 (running of that branch). ANy ideas how to fix this?

Tnx

The function tokenRequest in OAuth2CodeGrant does not allow specification of Headers for http basic authentication.

As a result, when trying to setup OAuth2 with reddit, it fails.

As a hack, I added this to allow it to work. But obviously it needs to be a little smarter about passing around the user/pass rather than doing a hardcoding.

    let username = “username“ //Client ID in Reddit
    let password = “password” //Client Secret in Reddit
    let loginString = NSString(format: "%@:%@", username, password)
    let loginData: NSData = loginString.dataUsingEncoding(NSUTF8StringEncoding)!
    var base64LoginString = "Basic "
    base64LoginString += loginData.base64EncodedStringWithOptions(NSDataBase64EncodingOptions.Encoding64CharacterLineLength)
    post.setValue(base64LoginString,forHTTPHeaderField: "Authorization")

I am trying to get a reauth token from reddit however the initial authorization url being generated using the same code flow detailed here - https://github.com/p2/OAuth2App/blob/master/OAuth2App/RedditLoader.swift - shows the following in log:

OAuth2: Authorizing against https://www.reddit.com/api/v1/authorize.compact?client_id=XXXXXXXXXXX&redirect_uri=reddit%3A%2F%2Fresponse&scope=identity%2Cedit%2Cflair%2Chistory%2Cmysubreddits%2Cprivatemessages%2Cread%2Creport%2Csave%2Csubmit%2Csubscribe%2Cvote&response_type=code&state=66BEFFB7

which shows no &duration=permanent in the url.

I am calling oauth2.authorize(params: ["duration":"permanent"]) but that still does not do the trick. Without reauth token support, there is no way to keep a user logged in for more than an hour without a manual relogin.

According to OAuth 2.0 RFC

expires_in
         RECOMMENDED.  The lifetime in seconds of the access token.  For
         example, the value "3600" denotes that the access token will
         expire in one hour from the time the response was generated.
         If omitted, the authorization server SHOULD provide the
         expiration time via other means or document the default value.

If expires_in is not present, each re-launch of the app will result in the error:

OAuth2: Found access token but it seems to have expired

Would it be possible to add an option to set a default expires in interval when one isn't provided by the access token response or treat the token as permanent?

Building and running works just fine, but trying to archive I get:

Command failed due to signal: Segmentation fault: 11

within the OAuth2iOS framework... any ideas?

I have done like this

  if(appDelegate.oauth.hasUnexpiredAccessToken()){

        println("Un-Expired Access Token")

        self.navigationController?.pushViewController(self.PersonalDriverUber_VC, animated: true)

    }else{

        println("Expired Access Token")

        appDelegate.oauth.onAuthorize = { parameters in
            println("Did authorize with parameters: \(parameters)")

            self.personalDriverLoader.stopAnimating()

            self.navigationController?.pushViewController(self.PersonalDriverUber_VC, animated: true)

        }
        appDelegate.oauth.onFailure = { error in        // `error` is nil on cancel
            if nil != error {
                println("Authorization went wrong: \(error!.localizedDescription)")
            }
        }


    }

at first time launch I am getting

Did authorize with parameters: [token_type: Bearer, expires_in: 2592000, access_token: laerXXXXX2NcXXXXXXXJc3mtT2t, refresh_token: DqWXXXXXXMBaKKFdPXXXXkZv, scope: request history, last_authenticated: 1431947251]
note: expires_in: 2592000 in the reponse

I want to know how to use the method hasUnexpiredAccessToken() to avoid login screen again and again. or there is any way to refresh the token

See my above code every time my ELSE block executes

Hi.
Thanks for providing this library. Im very close to getting this to work...
I'm using your GitHub example in iOS and upon authenticating I get "Cannot Open Page" in Safari.
I have properly registered the URL and if I paste it into Safari it opens the app correctly.
My redirect URI is set:
"redirect_uris": ["grid://oauth/callback"],

Im using the latest Xcode 6.1.1 and your master branch (not the Xcode 6.1 tag) but I do not get any build errors so I do not think that is the issue.

Any idea why Safari is stalling?

I have a need to add a password grant type, I have the bulk of the work done, but was curious if you would be open to me adding it to the library?

With the embedded web view, oauth2.forgetTokens() doesn't seem to clear everything out.

Tried setting keychain to false.

2nd call to oauth2.authorizeEmbeddedFrom(vc, params: nil) immediately returns success with the tokens, but I would like it to force the user to log in again.

Browser caching or something?

Thanks!

If a user signs out of my app, and then click sign in via Uber, they are automatically logged in with the credentials of the pervious user. How do I make it so that it allows me to sign out?

Is there a way to cancel an ongoing authorize() request?

In the readme it says:

oauth2.onFailure = { error in        // `error` is nil on cancel
    if nil != error {
        print("Authorization went wrong: \(error!.localizedDescription)")
    }
}

But the doc doesn't mention you can actually cancel the request..?
Is it possible?

after logging in once I've got a token, let's say I saved it somewhere safe is it possible after a reboot to initialize the object with the token and start doing requests with it immediately?

Following the Usage steps and I get:

Also, minor, but there's no note about the need for import Oauth2

I'm new, perhaps I missed a step and am causing my own problems? Note: xCode 6.2 (6C131e)

I faced a problem that the value of the param redirect_uri needed to be precent encoded. However the part in OAuth2.swift where the URL is composed with NSURLComponents (line 195) does not percent encode a value like 'http://some_redirect' and so the server gave a 500 error.
I had to this:
comp!.percentEncodedQuery = OAuth2.queryStringFor(urlParams).stringByAddingPercentEncodingWithAllowedCharacters(.URLHostAllowedCharacterSet())
to make it work...

The change in 36db55e seems only to be done for OSX, not iOS. Getting compile errors there

Here I have post the question on stackeoverflow

Any chance you can implement support for swift 2.0 / Xcode 7
thanks!

Any chance we can use a proper back button for back?

I'm not too sure where to ask this (GitHub repositories don't really have feature request pages), but is it possible to add SFSafariViewController to this framework? Now that we can submit iOS 9 apps, I'm sure that it would be a much better user experience.

I have a case where if my authentication server is not responding, afterAuthorizeOrFailure never calls the callback.

    typealias SuccessResponse = (Bool) -> Void
    typealias OAuth2Response = (wasFailure: Bool, error: NSError?) -> Void

    private func internalAuthorize(oauth2: OAuth2PasswordGrant?, callback: OAuth2Response) {

        if let oauth2 = self.oauth2 {

            oauth2.afterAuthorizeOrFailure = callback

            oauth2.authorize(params: nil, autoDismiss: true)
        } else {
            callback(wasFailure: true, error: nil)
        }
    }

    func authorize(email: String, password: String, callback: SuccessResponse) {

        let settings = [
            "client_id": OAuth.ClientId,
            "client_secret": OAuth.ClientSecret,
            "authorize_uri": OAuth.AuthorizeURI,
            "token_uri": OAuth.TokenURI,
            "scope": "",
            "redirect_uris": ["myapp://oauth/callback"],   // don't forget to register this scheme
            "keychain": true,
            "username": email,
            "password": password
        ] as OAuth2JSON

        oauth2?.forgetTokens() // We must explicitly call this to avoid data hanging around

        self.oauth2 = OAuth2PasswordGrant(settings: settings)

        if email != "facebook" {
            keychain["email"] = email
            keychain["password"] = password
            keychain["lastAuthentication"] = "email"
        }

        self.internalAuthorize(self.oauth2) { (wasFailure, error) -> Void in
            log.debug("\(wasFailure)") // This never happens
            callback(!wasFailure)
        }

        // Update device token for push notifications
        UserService().updateMyDevice(PFInstallation.currentInstallation().deviceToken, callback: { (success) -> Void in
            print(success)
        })
    }

This is probably a "me" error, but I'm not sure.

Hi again!

I am getting an access token, but my requests are resulting in "Bad credentials"
Did authorize with parameters: {
"access_token" = XXX...xje3x3EGww4lTIlTZYEgfb2saUOtsgsSip5DENe;
"token_type" = Bearer;
}

Here is my request method (i did try to manually set the Authorization header):

func request(path: String, callback: ((dict: NSDictionary?, error: NSError?) -> Void)) {
        let url = baseURL.URLByAppendingPathComponent(path)
        let req = oauth2.request(forURL: url)

        req.setValue("application/vnd.github.v3+json", forHTTPHeaderField: "Accept")
//        req.setValue("Bearer \(oauth2.accessToken)", forHTTPHeaderField: "Authorization")

        let session = NSURLSession.sharedSession()
        let task = session.dataTaskWithRequest(req) { data, response, error in
            if nil != error {
                dispatch_async(dispatch_get_main_queue(), {
                    callback(dict: nil, error: error)
                })
            }
            else {
                var err: NSError?
                let dict = NSJSONSerialization.JSONObjectWithData(data, options: nil, error: &err) as? NSDictionary
                dispatch_async(dispatch_get_main_queue(), {
                    callback(dict: dict, error: err)
                })
            }
        }
        task.resume()
    }

Any ideas?

I got a weird problem since I updated to 8.4 SDK - on a live device running either 8.3. or 8.4 the OAuth will instantly fail on the WebView where you enter your credentials.

The Log:

as Docs suggested,
either use the built-in web view controller or manually open the authorize URL in the browser:

I am using built-in web view controller approach.

I am trying like this

    appDelegate.oauth.afterAuthorizeOrFailure = { wasFailure, error in

        println("Test afterAuthorizeOrFailure")
        web.dismissViewControllerAnimated(true, completion: nil)
    }

But I getting no crash but this warning and nothing open up.

may be I am commiting a mistake while making my WebViewController's Object.

Swift 1.2 support would be awesome!

Is it best to call oauth2.authorize() before any API calls are made to ensure that if the token has expired then it is refreshed?

puzzled how to use the refresh method?

Hello.

Some time ago we discussed (#25) a way to clear cookies in the web view in a "log out" scenario.
This was the snippet that handled that:

let storage = NSHTTPCookieStorage.sharedHTTPCookieStorage()
        for cookie in storage.cookies! {
            storage.deleteCookie(cookie)
        }
        NSUserDefaults.standardUserDefaults()

Now with SafariViewController this approach won't work, and I understand why.

My question is do you have any idea of another approach to address the issue?

Hi - I am running XCode 7.01 and having trouble properly linking the p2.OAuth2 library to my project. Are the current versions of Swift and XCode supported?

In OAuth2Base i have some problems with

        let parts = split(query.characters) { $0 == "&" }.map() { String($0) }
        var params = [String: String](minimumCapacity: parts.count)
        for part in parts {
            let subparts = split(part.characters) { $0 == "=" }.map() { String($0) }
            if 2 == subparts.count {
                params[subparts[0]] = subparts[1].wwwFormURLDecodedString
            }
        }

        return params
    }

It says following

p2.OAuth2/OAuth2/OAuth2Base.swift:203:15: 'split(_:maxSplit:allowEmptySlices:isSeparator:)' is unavailable: Use the split() method instead.

Any idea what is is?

Using the latest Xcode beta and iOS 9 beta on OS X 10.10.4

Hi,

I'm using OAuth2PasswordGrant in my project and I don't think the "password" flow is fully implemented.

First, OAuth2PasswordGrant will try to use the authorization_uri instead of the token_uri to request and access_token using the username and password. (This can be hacked by using the a token uri as the authorization_uri value).

Second, I believe all grant types allow to refresh access_token using the refresh_token. I just see this implemented in OAuth2CodeGrant. I think all the refresh logic (refreshToken, doRefreshToken(), ...) should be shared with OAuth2PasswordGrant.

Cheers.

I wasn't able to compile this for OSX

NSURLSession.dataTaskWithRequest() is returning empty data and a 200 http code immediately, without actually making an outbound http call to the server using sample code in the readme. Adjusted the sample code as below and fixed it. Think it has something to do with async nature of this call?

    let session = NSURLSession.sharedSession()
    let task = session.dataTaskWithRequest(req) {
        (
        let data, let response, let error) in

        guard let _:NSData = data, let _:NSURLResponse = response  where error == nil else {
            print("error")
            return
        }

Hi quick question,

I am currently using the Password Grant to authenticate my users. However, my 'username' and 'password' fields are dependent on my UITextFields. I am unable to set this as I will be getting a 'instance member cannot be used on type view controller'. How do I go about doing this? Thanks!

I am trying to get access token for Linkedin. As mentioned in the usage section, I have created the following code for getting access token.

  let settingsLinkedin = [
        "client_id": "75afkn125135v14",
        "client_secret": "R5gHlmkRtld4xge4",
        "authorize_uri": "https://www.linkedin.com/uas/oauth2/authorization",
        "token_uri": "https://www.linkedin.com/uas/oauth2/accessToken",
        "scope": "",
        "redirect_uris": ["http://www.dummyredirecturl.com/oauth.aspx"],   // don't forget to register this scheme
        "keychain": false        ] as OAuth2JSON            // the "as" part may or may not be needed


        let oauth2 = OAuth2CodeGrant(settings: settingsLinkedin)
        oauth2.onAuthorize = { parameters in
            println("Did authorize with parameters: \(parameters)")
        }
        oauth2.onFailure = { error in        // `error` is nil on cancel
            if nil != error {
                println("Authorization went wrong: \(error!.localizedDescription)")
            }
        }


        oauth2.authConfig.authorizeEmbedded = true
        oauth2.authConfig.authorizeContext = self.view.window!.rootViewController
        //oauth2.authConfig.ui.backButton = <# UIBarButtonItem(...) #>    // to customize go-back button
        oauth2.authorize()

The problem is that when I use it with Linkedin, it gives following error:

Authorization went wrong: missing required parameters, includes an
invalid parameter value, parameter more than once. : client_secret

When I use implicit-grant, I get following error, even before the user credentials form comes up:

Authorization went wrong: Invalid redirect URL:
http://www.dummyredirecturl.com/oauth.aspx?error=unsupported_response_type&error_description=We+only+support+a+response_type+of+%22code%22%2C+but+you+passed+token

Also, when I use the above code for Facebook (of-course after changing credentials) , it works correctly.

Maybe I am missing something but I dont see how to check if the user if authorized without starting the entire OAuth dance.

When my app is launched, I want to check to see if the user is authorized. If they are, I would use the access token like normal but if they ARE NOT I want to display a button that says "Sign In" which would THEN trigger the typical OAuth dance. This seems to be fairly standard for apps (i.e. when you start it up, if they are logged in just keep them logged in without requiring them to click sign in) but Im not sure how to do it.

Thanks.

Hello!

Is there a plan to implement p2.oauth2 in Alamofire in someway ?

I think it could be nice, so you don't need to set the tokens when you make a request.

I am implemeting your framework in my App and I have some questions:

1. Why it don't support "client_id & client_secret" in body?
2. On authorization I receive this warning: "WARNING: expecting “bearer” token type but got “Bearer”", why? There are no difference between "Bearer" and "bearer", but it is not nice to see a useless warning when debug. Many OAuth providers use both variants.
3. What mean "params" array and "autoDismiss" boolean? There are information in Docs. If they are useless, then why there are required? oauth2.authorize(params: nil, autoDismiss: true);
4. Why it use for requesting "access_token" the "authorize_uri"? In Password Grant it must request directly the "token_uri".
5. parameters in oauth2.onAuthorize returns empty string.

oauth2.onAuthorize = { parameters in
    print("Did authorize with parameters: \(parameters)")
}

Console: Did authorize with parameters: [:]
