i am using this library for Uber Authetication https://developer.uber.com/v1/auth/

I have done like this

func doOAuthUber(){

    let oauthswift = OAuth2Swift(
        consumerKey:    "fXfXXXXXXXUo9vtKzobXXXXXUDO",
        consumerSecret: "e5XXXXXXXq2w63qz9szEx7uXXXXXXo03W",
        authorizeUrl:   "https://login.uber.com/oauth/authorize",
        accessTokenUrl: "https://login.uber.com/oauth/token",
        responseType:   "code"
    )

    var originalString = "jamesappv2://oauth/callback"
    var encodedCallBackUrl = originalString.stringByAddingPercentEncodingWithAllowedCharacters(.URLHostAllowedCharacterSet())

    println("encodedCallBackUrl: \(encodedCallBackUrl)")


    let state: String = ""
    oauthswift.authorizeWithCallbackURL( NSURL(string: encodedCallBackUrl!)!, scope: "request%20history", state: state, success: {
        credential, response in

        println(credential.oauth_token)
        self.personalDriverLoader.stopAnimating()



        }, failure: {(error:NSError!) -> Void in

            self.personalDriverLoader.stopAnimating()
            println(error.localizedDescription)
    })


}

but getting this response HTTP Status 401: Unauthorized, Response: {"error": "invalid_client"}

I have triple checked that my client_id (consumerKey) and secret (consumerSecret) are correct. What I have done wrong here

Please help

I ccompared with that web site : http://oauth.googlecode.com/svn/code/javascript/example/signature.html

the signature calculated in OAuthSwiftClient, authorizationHeaderForMethod give wrong value. this imply that on some web site, upload fail. here is something I did, which works.

hope this help. Olivier

Hi there,

I'm having trouble building our project after upgrading to XCode8 and Cocoapods 1.1.0.rc.2. Our project is objective-c based and everything was working fine until today. Basically I'm seeing 76 errors in the Pod when it tries to build it.

We are currently importing OAuthSwift using @import OAuthSwift statement. I've tried to switch that to #import "OAuthSwift-swift.h" but there issues are still there. Kind of makes sense as it isn't actually able to build the pod.

A lot of the issues appear to be related to syntax error which leads me to believe it is something to do with Swift 3 or 2.3 updates. I'm not up on Swift yet but an example error is "Expected 'let' in conditional"

Our Podfile.lock file shows that we are using OAuthSwift 0.6.0

Any ideas?

This includes both changes suggested by Xcode's migration tool as well as manual fixing of the issues that Xcode couldn't migrate.

Action list:

• [ ] Double-check Int+OAuthSwift.swift
• [ ] Code review
• [ ] Squash commits
• [x] Get tests to work again
• [x] Fix test failures

Summary

Access tokens have an expiration date but OAuthSwift doesn't automatically refresh access tokens by default.

This PR proposes a solution:

• that makes OAuthSwift automatically refresh access tokens when they expire
• which is opt-in by providing one simple convenient method
• containing the minimum amount of changes needed to avoid to break existing apps

Related links:

• Issue #217
• PR #209

Changes:

• Add a new function requestWithAutomaticAccessTokenRenewal in OAuthSwiftClient. When used, it automatically refreshes the access token if it expired and restart the query.
• Move the implementation for renewAccessToken and requestOAuthAccessToken from OAuth2Swift to OAuthSwiftClient. The methods renewAccessToken and requestOAuthAccessToken are still available in OAuth2Swift but they simply forward the call to OAuthSwiftClient to ensure that old apps don't need to be changed.

Why?

I developed an application, called Clatters, that needs to access various services relying on OAuth. Rather that creating my own OAuth library, I decided to use OAuthSwift as it perfectly fit my needs.

However I believe that OAuthSwift should automatically refresh access tokens when they expire. The app itself shouldn't have to implement the logic to handle expired token.

Clatters has been available in the iOS App Store since February 2020 and relies on the code written in this PR.

Usage

You can call the convenient method requestWithAutomaticAccessTokenRenewal in OAuthSwiftClient with the correct parameters. If the access token expired, requestWithAutomaticAccessTokenRenewal will automatically renew the access token and retry the query. Here is an example to perform a query on Reddit:

static func requestIdentity(client: OAuthSwiftClient) {
		client.requestWithAutomaticAccessTokenRenewal(url: URL(string: "https://oauth.reddit.com/api/v1/me")!, method: .GET, headers: nil, contentType: nil, accessTokenBasicAuthentification: true, accessTokenUrl: "https://www.reddit.com/api/v1/access_token", onTokenRenewal: nil) { (result) in
			switch result {
				case .success(let response):
					// Do something
					debugPrint("Received \(response)")
					break
				case .failure:
					// Fail nicely
					break
			}
		}
    }

Notes

I wanted to keep the changes proposed in this PR really simple. As previously mentioned:

• this new feature is opt-in by using a convenient method.
• apps already using OAuthSwift shouldn't be affected and don't need to adopt the new API.
• no code has been removed or deprecated.

Guys, i know this is probably a lame question, but.. How can i modify de webview ? In my app i have everyrhing under a navigation crontoller, when login in with the oauthswift , i get ro this plain blank uiviewcontroller in blank, it takes the whole screen .. I get instagram textfields and interface almost overlapoing the status bar. I would like to get that webview viewconteoller inside of my navigstion controller etc

Greetings! My team has started using this fabulous library in our inner-source auth library which will be used in 6 (and probably more) of our company's public iOS apps. We are using PingFederate as our OAuth server.

I have noticed that there are two new GitHub releases (2.1.1 & 2.1.2) that have been tagged but not yet released to CocoaPods trunk. Version 2.1.0 is the latest that shows up on CocoaPods.

I would like to help out with publishing these and future releases to CocoaPods. I just need @phimage or @dongri to run the following command to add me as an owner of this pod.

pod trunk add-owner OAuthSwift [email protected]

Note that all CocoaPods trunk session keys have been wiped due to a recent trunk vulnerability, so you'll probably need to authenticate again with pod trunk register.

I have lots of experience publishing libraries to CocoaPods trunk and also publish our own 20+ internal iOS libraries to a private repo.

This updates OAuthSwift version in OAuthSwift.podspec to 2.1.3, assuming this is the version to be used for the upcoming release.

OAuthSwift 2.1.2 has been already released and tagged, but since it was marked as 2.1.0 in podspec (https://github.com/OAuthSwift/OAuthSwift/blob/2.1.2/OAuthSwift.podspec) it can not now be used with CocoaPods. This can't be resolved without altering the tag, but, going forward, this commit ensures that upcoming 2.1.3 is going to have the right version in the OAuthSwift.podspec file and can be then published on CocoaPods.

Description:

Call to /request_token after canceling a request fails with an HTTP error 401 because credential.oauth_token is already set and is passed to the headers parameters. I am trying to verify that we can correctly cancel a login attempt to Garmin made with our view controller that implements OAuthWebViewController. We are canceling the login attempt like this:

var service: OAuthSwift?
private func cancelFlow() {
    service?.cancel()
    dismissWebViewController()
}

But if we try to call service.authorize again, the call fails without opening our custom OAuthWebViewController with a 401 unauthorized error, and the difference is that in the second call the oauth_token parameter is set.

Are we canceling the request the wrong way? Is Garmin supposed to check oauth_token? Is oauth_token supposed to be still set after canceling a request?

Description:

This one is a little difficult to explain, so bear with me.

We use Azure B2C to handle authentication and OAuthSwift to handle that communication. Everything works great and has for quite some time.

Recently, we updated our B2C configuration to use Apple ID for some customers. However, instead of redirecting to a web site that allows the user to enter username/password, iOS brings up a specialized / native Apple ID view. This works great if the user successfully authenticates.

However, if the user cancels out of that process, then OAuthSwift never gets the memo and will basically hang forever since it never got a notification that the Auth flow was canceled.

I spent a long time trying to hook the Apple ID cancel message, but couldn't figure out how to do it. You can detect that the scene has resigned active but that isn't enough information to meaningfully act upon because other actions (like an incoming phone call or more importantly FaceID to access stored passwords) will also generate that scenario.

This issue is described in this stackoverflow: https://stackoverflow.com/questions/70130072/cannot-detect-if-user-pressed-cancel-button-on-wkwebview-sign-in-with-apple-pop

I have no idea what to try next - it seems to me that OAuthSwift should be able to detect the user cancelling out of the Apple ID auth just like it does when the user cancel's out of any IDP shown in the browser window.

This is what the native Apple ID screen looks like on an iPad:

This fixes error handling, and makes a couple of improvements to implementation of the requestWithAutomaticAccessTokenRenewal function:

• Pass all error responses as-is, and look only for the tokenExpired;
• Treat onTokenRenewal parameter as truly optional - perform the token renewal even if onTokenRenewal is nil;
• Do not keep a strong reference to self in the completion block for renewAccessToken call.

The main issue I had was that requestWithAutomaticAccessTokenRenewal would swallow all errors and convert them to the empty tokenExpired errors, preventing any possibility of implementing custom error handling logic on the client side:

completion(.failure(.tokenExpired(error: nil)))

I want to use the twitch login option but I can't add a URL scheme on the Twitch Dev portal. So, how can I get data without CallbackURL?
