Constants ¶
const ( // BanDuration specifies how long a user will be banned in the group. BanDuration = 60 * time.Second // Timeout specifies how long the captcha question will be valid. // After this time, the user will be kicked. // Or banned exactly, for one hour. Timeout = 61 * time.Second )
Variables ¶

Types ¶
type Captcha ¶
type Captcha struct {
// Store the correct answer for the captcha
Answer string `json:"a"`
// Expiry time for the captcha
Expiry time.Time `json:"e"`
ChatID int64 `json:"c"`
SenderID int64 `json:"s"`
QuestionID string `json:"q"`
AdditionalMessages []string `json:"am"`
UserMessages []string `json:"um"`
}
Captcha struct keeps all the data needed for the captcha for a certain user.
It will be converted to JSON format (as array of bytes or []byte) and then will be stored to the in memory cache, with the key of the corresponding Telegram User ID.
type Dependencies ¶
type Dependencies struct {
DB *badger.DB
Memory *bigcache.BigCache
Bot *tb.Bot
TeknumGroupID int64
}
Dependencies contains the dependency injection struct for methods in the captcha package.
func (*Dependencies) CaptchaUserJoin ¶
func (d *Dependencies) CaptchaUserJoin(ctx context.Context, m *tb.Message)
CaptchaUserJoin is the most frustrating function that I've written at this point of time.
As the function name says, it will prompt a captcha to the incoming user that has just joined the group.
At the end of the function, it will create 2 goroutines in which both of them are responsible for kicking the user out of the group.
func (*Dependencies) CaptchaUserLeave ¶
func (d *Dependencies) CaptchaUserLeave(ctx context.Context, m *tb.Message)
CaptchaUserLeave handles the event when a user left the group. This will check if the user is in the memory of current active captcha or not.
If it is, the captcha will be deleted.
func (*Dependencies) Cleanup ¶
func (d *Dependencies) Cleanup()
Cleanup will iterate over every keys and make sure the expiry has not been exceeded by 10 seconds. If it is, we'll kick the person.
func (*Dependencies) NonTextListener ¶
func (d *Dependencies) NonTextListener(ctx context.Context, m *tb.Message)
NonTextListener is the handler for every incoming payload that is not a text format.
func (*Dependencies) WaitForAnswer ¶
func (d *Dependencies) WaitForAnswer(ctx context.Context, m *tb.Message)
WaitForAnswer is the handler for listening to incoming user message. It will uh... do a pretty long task of validating the input message.
