I'm using a service that provides an OAuth2.0 authentication. This are the steps i need:
- Open a URL with user Id as params
- User approves my app (which is correctyle registered).
- The user is redirected to a RedirectUri, with access token in the hash.
The third point is my main problem.
I've implemented the OAuth with microsoft libraries and everything works fine. But I cant use them here so I'm trying https://github.com/OAuthSwift/OAuthSwift this one.
This is my code:
private func authenticationService() {
// create an instance and retain it
let oauthswift = OAuth2Swift(
consumerKey: "xx",
consumerSecret: "xxx",
authorizeUrl: "//myurl + userId",
responseType: "token"
)
oauthswift.authorizeURLHandler = OAuthSwiftOpenURLExternally.sharedInstance
let handle = oauthswift.authorize(
withCallbackURL: "???",
scope: "", state:"") { result in
switch result {
case .success(let (credential, response, parameters)):
print(credential.oauthToken)
// Do your request
case .failure(let error):
print(error.localizedDescription)
}
}
}
This open correctly my Safari but then I'm redirected to the URI with access token in the hash and nothing happened.
The main problem here is that I've a redirect uri so I guess the callback URL is not called? And this is not opening a sheet but it is redirecting to Safari. And I dont like this approach.
How can I perform OAuth2.0 in swift with the steps above? How can I get the access token from an url? What is the best library and how can I get the most of it?
Update:
This is my code for stackExchange:
let request: OAuth2Request = .init(authUrl: "https://stackexchange.com/oauth/dialog?client_id=<MYCLIENTID>&scope=private_info&redirect_uri=https://stackexchange.com/oauth/login_success",
tokenUrl: "https://stackoverflow.com/oauth/access_token/json",
clientId: "<MYCLIENTID>",
redirectUri: "https://stackexchange.com/oauth/login_success",
clientSecret: "",
scopes: [])
The OAuth domain in stack apps is => stackexchange.com
So i've added in my URL Types the following: redirect-uri://<stackexchange.com> (even without <>)
But everytimes I approve my app i'm stacked in the "Authorizing application" which contains my token and i'm not redirected.
This is super interesting, I'm trying this. I'm trying to implement OAuth with StackExchange, but I really cant figure out how to do it. I'm adding all the info required but once the "Authorize" page prompr and I click it, i'm redirected to a new page and I'm not able to close the "authentication sheet" in order to get the token. Have you tried with StackExchange? I would really appreciate any kind of help
I tried GitLab only, will try StackExchange and get back to you 👍🏻
It's working now, you can use the 1.0.4 version of the package, I change the OAuth2Credentials struct to the one defined in RFC 6749 OAuth 2.0 tools.ietf.org/html/rfc6749#section-5.1. StackExchange is returning "expires" but the recommended one is "expires_in", so I handle this in the new version. PS: For redirecting you need to register your scheme in target>info>URL Types. Something like "redirect-uri://<<your domain on stackApps>>" will works. Tell me if it's working for you now and if I need to edit the library, I am always opened for modification since I am using it in my apps
Also don't forget to use the JSON format of the access token response "stackoverflow.com/oauth/access_token/json"
you are so kind. I really appreciate your help and ill share your library. But i'm still facing the issue, I updated my answer with all the details. You tried the StackExchange Oauth right? And i'ts working? Is there anything different between my update and your code?
