Methods

These are the methods provided by the Wepin iOS Login Library.

Methods can be used after initialization of Wepin Login Library.

loginWithOauthProvider

await wepin!.loginWithOauthProvider(params)

An in-app browser will open and proceed to log in to the OAuth provider. To retrieve Firebase login information, you need to execute either the loginWithIdToken() or loginWithAccessToken() method.

Parameters

• params <WepinLoginOauth2Params>

  • provider <'google'|'naver'|'discord'|'apple'> - Provider for login

  • clientId <String>

• viewController <UIViewController>

Returns

• <WepinLoginOauthResult>

  • provider <String> - login provider

  • token <String> - accessToken (if provider is "naver" or "discord") or idToken (if provider is "google" or "apple")

  • type <WepinOauthTokenType> - type of token

Exception

• Wepin Login Error

Example

    do {
        let oauthParams = WepinLoginOauth2Params(provider: "discord", clientId: self.discordClientId)
        let res = try await wepin!.loginWithOauthProvider(params: oauthParams, viewController: self)
        let privateKey = "private key for wepin id/access Token"
        // token sign 
        let sign = wepin!.getSignForLogin(privateKey: privateKey, message: res.token)
        //call loginWithIdToken() or loginWithAccessToken()
    } catch (let error){
        self.tvResult.text = String("Faild: \(error)")
    }

signUpWithEmailAndPassword

await wepin!.signUpWithEmailAndPassword(params: params)

Sign up for Wepin Firebase with an email and password.

getSignForLogin

Generates signatures to verify the issuer. It is mainly used to generate signatures for login-related information such as ID tokens and access tokens.

wepin!.getSignForLogin(privateKey: privateKey, message: "")

Parameters

• privKey <String> - The authentication key used for signature generation.

• message <String> - The message or payload to be signed.

The key for signing can be obtained from Wepin Workspace. In the Development Tools menu, click Get your authentication key on the Login tab to retrieve the authentication key.

• String - The generated signature.

The authentication key (privKey) must be stored securely and must not be exposed to the outside. It is recommended to execute the getSignForLogin() method on the backend rather than the frontend for enhanced security and protection of sensitive information.

Example

let privKey = '0400112233445566778899001122334455667788990011223344556677889900'
