This repository holds a rewrite of my Python-GeizhalsBot Telegram bot in the Go programming language. GoGeizhalsbot is a Telegram bot that notifies you via chat messages about changes of the price of a geizhals.de product or wishlist.
The software searches for a config.yml file in the current working directory. Check config.sample.yml for an example. This section gives a quick overview of the possible configuration items.
On the root level of the config file you can set the bot token.
| Field | Type | Function |
|---|---|---|
| bot_token | string | The bot token to run the bot on |
| update_interval_minutes | int | Interval for fetching price updates in the background in minutes |
| http_max_tries | int | Number of max tries for http requests |
| max_price_agents | int | Number of max allowed price agents per user |
Long polling isn't all too bad, but using webhooks cuts out the need of constantly contacting the Telegram server for new updates.
The webhook key of the config allows you to set up a webhook for the bot.
| Field | Type | Function |
|---|---|---|
| enabled | bool | Specifies if the bot should use webhooks |
| listen_ip | string | The IP for the webhook to listen on |
| listen_port | int | The port for the webhook to listen on |
| listen_path | string | The path to listen on (e.g. "/" or "/bot") |
| url | string | The publicly reachable url which Telegram calls (passed in SetWebhook) |
| cert_path | string | Path to a certificate file to use |
| cert_key_path | string | Path to the certificate key file |
Contacting the geizhals.de website regularly will get your IP address banned in no time.
Therefore, it is recommended to use proxy servers to circumvent this. Use the proxy key to configure your proxy servers.
| Field | Type | Function |
|---|---|---|
| enabled | bool | Specifies if the bot should use proxies for the connection to Geizhals |
| proxy_list_path | string | Path to a file that contains a newline separated list of proxy addresses |
Monitoring your services is always a good idea.
Prometheus is a time series database that allows you to collect metrics over time and render them in cool graphs e.g. with tools like Grafana.
This configuration can be found on the prometheus key.
| Field | Type | Function |
|---|---|---|
| enabled | bool | Specifies if the prometheus interface is active |
| export_ip | string | The IP adress to run the export http server on |
| export_port | int | The port number to run the export http server on |
