Golang Config.PasswordCredentialsToken方法代碼示例

// Token refreshes the token by using a new client credentials request.
// tokens received this way do not include a refresh token
// Token returns a token or an error.
// Token must be safe for concurrent use by multiple goroutines.
// The returned Token must not be modified.
