userInfoUrl is outdated - just update the version to the current

[speckmoor]

First of all it is an amazing Tutorial, one of the best I have read over the years. Thank you so much for covering the OAuth Topics.

When implementing OAuth with google I ran into the following exception:

Field 'locale' is required for type with serial name '.UserInfo', but it was missing at path: $ for request https://www.googleapis.com/oauth2/**v1**/userinfo"

Just update the version please and additional to that I changed the getUserInfo function to be more robust about any API changes from Google.

suspend fun getUserInfo(accessToken: String, oauthConfig: OAuthConfig, httpClient: HttpClient): UserInfo { val response = httpClient.get(oauthConfig.userInfoUrl) { headers { append("Authorization", "Bearer $accessToken") } } val jsonObject = Json.decodeFromString<JsonObject>(response.bodyAsText()) return UserInfo( id = jsonObject["sub"]?.jsonPrimitive?.contentOrNull ?: "", email = jsonObject["email"]?.jsonPrimitive?.contentOrNull, name = jsonObject["name"]?.jsonPrimitive?.contentOrNull, picture = jsonObject["picture"]?.jsonPrimitive?.contentOrNull, familyName = jsonObject["picture"]?.jsonPrimitive?.contentOrNull, givenName = jsonObject["picture"]?.jsonPrimitive?.contentOrNull, locale = jsonObject["picture"]?.jsonPrimitive?.contentOrNull )

(You need to change the Types in the data class to String? as well but Idea will tell you that.)
