How does google oauth work in react core?


Asked by Isaiah McDaniel on Dec 04, 2021 React



Once the token is received, it is verified by the backend server by calling GoogleJsonWebSignature.ValidateAsync method from the Google Auth API. Once validated, this is then internally authenticated to find if the user exists, and if not create it. This all happens in the AuthService implementation described above.
In respect to this,
Google then redirects the user back to your app. The redirect includes an access token, which your app verifies and then uses to make API requests. Note: Given the security implications of getting the implementation correct, we strongly encourage you to use OAuth 2.0 libraries when interacting with Google's OAuth 2.0 endpoints.
Besides, Applications that use JavaScript to make authorized Google API requests must specify authorized JavaScript origins. The origins identify the domains from which your application can send requests to the OAuth 2.0 server.
Also Know,
In that case, proceed with that API request. Generate a URL to request access from Google's OAuth 2.0 endpoint at https://accounts.google.com/o/oauth2/v2/auth. This endpoint is accessible over HTTPS; plain HTTP connections are refused. The client ID for your application. You can find this value in the API Console Credentials page.
Subsequently,
We have a React single page application (SPA) which acts as Oauth2 client, this SPA uses OAuth2 endpoints (authorize, toke & revoke) of the custom OAuth2 provider to authorize end-users. For a React SPA, is there any library/SDK available to implement the OAuth2 Authorization code grant (with PKCE) for a custom OAuth2 provider ?.
