linkedin scopes updated to 'profile' and 'email' according to update …

[Rushikesh7888]

This pull request updates the LinkedIn OAuth scopes in the goth package to align with LinkedIn’s latest API requirements. LinkedIn has deprecated the previous scopes r_liteprofile and r_emailAddress and replaced them with profile and email. This change is essential to ensure that LinkedIn authentication continues to work as expected without encountering permission errors.

Changes Made:

Updated LinkedIn OAuth scopes in the relevant files from:

• r_liteprofile ➔ profile
• r_emailAddress ➔ email

Reason for Change: LinkedIn recently changed its API scope requirements, making r_liteprofile and r_emailAddress obsolete. Using the new scopes profile and email ensures compatibility with LinkedIn's API and allows applications to retrieve the necessary profile and email information without issues.

@Rushikesh7888 - I was curious, did you try this? I think you have to update the fetch user endpoint as well and parse the userInfo differently from the OID response. Also the email comes along so we no longer need a separate request for that:

const (
    userEndpoint string = "//api.linkedin.com/v2/userinfo"
)


func userFromReader(reader io.Reader, user *goth.User) error {
	u := struct {
		Sub        string `json:"sub"`
		Name       string `json:"name"`
		GivenName  string `json:"given_name"`
		FamilyName string `json:"family_name"`
		Picture    string `json:"picture"`
		Locale     struct {
			Language string `json:"language"`
			Country  string `json:"country"`
		} `json:"locale"`
		Email         string `json:"email"`
		EmailVerified bool   `json:"email_verified"`
	}{}

	err := json.NewDecoder(reader).Decode(&u)
	if err != nil {
		return err
	}

	// Populate the goth.User fields
	user.UserID = u.Sub
	user.FirstName = u.GivenName
	user.LastName = u.FamilyName
	user.Name = u.Name
	user.NickName = u.GivenName
	user.AvatarURL = u.Picture
	user.Email = u.Email

	// Optionally, use locale data if needed
	// user.Locale = fmt.Sprintf("%s-%s", u.Locale.Language, u.Locale.Country)

	return nil
}
