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")

    }getSignForLogin(Deprecated)
🔄 getSignForLogin is no longer supported
• Starting from v1.1.0, the getSignForLogin() function is no longer supported because the sign parameter has been removed from the login process.
• To log in without a signature, please delete the authentication key from Wepin Workspace > Development Tools menu > Login tab > Auth Key > Delete
• The "Auth Key" menu is only visible if a key has been previously generated.
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.
Returns
- 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'
let idToken = 'idtokenabcdef'
let sign = wepin!.getSignForLogin(privateKey: privKey, message: idToken)finalize
wepin!.finalize()This method finalizes the Wepin Login Library.
