It uses long +polling and can run on the JVM or as a Kotlin/Native executable. -## Launch +## Behavior + +The bot registers one command: + +- `/send_file` requests one file; +- `/send_file N` requests `N` files when `N` is a positive integer; and +- a missing or non-numeric count defaults to one. Zero and negative counts select nothing and receive + `Nothing selected :(`. + +For each requested file, the picker starts at the configured root. A file root is selected directly; a directory root +is searched by choosing one random child at each level until a file is reached. This is not a uniform choice among all +files in an uneven directory tree, and the same file may be selected more than once. Zero-byte files and unsuccessful +selections are retried. Consequently, a positive request can keep retrying indefinitely when no non-empty file is +reachable. + +One file is sent as a document. Multiple files are sent as document media groups, split at Telegram's maximum media +group size. All sends enable Telegram's protected-content flag. The bot also prints its own account information at +startup and prints polling exceptions. + +## Setup and security + +Create a bot with BotFather and obtain its token.

These launchers accept it on the command line, where it may be retained in shell history or be +visible to other local processes. Also avoid roots containing secrets or links to locations outside the intended tree. + +## Arguments + +Both launchers interpret arguments in the same order: + +1. `BOT_TOKEN` (required). Omitting it fails immediately. +2. `ROOT_PATH` (optional in code), either a file or directory.

Three +additional handlers can be invoked by typing their commands manually. + +| Command | In menu | Demonstration | +| --- | --- | --- | +| `/rich_html` | Yes | Sends the full HTML fixture: inline styles and links, references, emoji and time links, math, headings, lists and checkboxes, quotations, remote media and maps, collages, slideshows, tables, details, and captions. | +| `/rich_markdown` | Yes | Sends and logs the corresponding Markdown fixture, including remote photo, video, audio, voice-note, animation, collage, and slideshow markup. | +| `/rich_markdown_medialess` | No | Sends and logs the Markdown fixture without media, collages, or slideshows. | +| `/rich_markdown_blocks` | No | Sends and logs the full fixture as a typed block tree, including first-class media blocks, captions, collages, and slideshows. | +| `/rich_markdown_medialess_blocks` | No | Sends and logs the same typed block tree without its media section. | +| `/rich_blocks` | Yes | Sends a smaller, directly constructed block tree with headings, formatted paragraphs, ordered and unordered checkbox lists, a divider, preformatted Kotlin, and a quotation. | +| `/rich_draft` | Yes | Streams three Markdown revisions under draft ID `1`, one second apart, then sends a normal final rich message. | +| `/rich_blocks_draft` | Yes | Streams two draft-only `thinking()` blocks under draft ID `2`, one second apart, then sends a normal typed-block answer. | +| `/rich_edit` | Yes | Sends a Markdown rich message, waits two seconds, and replaces its rich content with `EditChatMessageRichText`. | +| `/wait_rich` | Yes | Prompts for a rich message, waits for the next matching content, and reports its block count. | + +The two draft examples finalize by sending a new normal rich message; they do not +turn the draft itself into the final message. They use distinct fixed IDs (`1` +and `2`); concurrent runs of the same command in one chat reuse that command's +ID. + +## Other triggers + +| Trigger | Behavior | +| --- | --- | +| Any photo | Reuses the received Telegram file ID without downloading it. The bot first sends HTML whose `tg://photo?id=userphoto` reference is resolved by `InputRichMessageMedia`, then sends the same photo as a typed `photo()` block. | +| Any incoming rich message | Logs right-to-left state and every parsed block, replies with the block count, and resends the rich message with `createResend`. The `onlyRichMessageContentMessages` flow also logs its block count. | +| Any inline query | Returns uncached HTML and Markdown articles whose selected messages use `InputRichMessageContent`. | +| A text guest request containing `/rich_guest` | Returns one inline article containing the full Markdown fixture. This is a substring check, not a registered bot command. Non-text guest requests and text without that exact case-sensitive substring are ignored by this handler. | + +Every received update is also printed to standard output. A rich message received +while `/wait_rich` is active can therefore be observed by the waiter, the general +rich-message trigger, and the filtered update flow. + +## Media notes + +The built-in HTML and Markdown fixtures refer to public files under +`https://telegram.org/example/`. The typed full fixture constructs Telegram media +from the same URLs. The photo trigger instead demonstrates reusing an existing +Telegram file ID and assigning an alias for a `tg://photo?id=...` reference. + +The source also shows the two library shapes used for rich media: an +`InputRichMessageMedia` mapping for markup references and first-class photo, +video, audio, voice-note, animation, collage, and slideshow blocks. The library +can collect multipart files nested in a rich-message tree as `attach://` uploads, +although this example's running handlers use URLs or an existing file ID. + +## Telegram setup and permissions + +1. Create a bot with BotFather and obtain its token. Keep the token out of source + control. +2. Start a private chat with the bot, or add it to a chat and allow it to send + messages and media. +3.

Use `/start` with bot to get simple info about webhooks +A webhook-based example bot with an embedded Ktor CIO server. It registers a public webhook URL with Telegram, accepts update POSTs on a matching local route, and dispatches them through a behavior context; it does not use long polling. + +## Server and bot behavior + +- The server binds plain HTTP to `0.0.0.0` on the selected port (`8080` by default) and blocks until it is stopped. +- With no subpath, webhook POSTs are handled at `/`. With a subpath such as `telegram/hooks`, they are handled at `/telegram/hooks`, and that path is appended to the registered public address. +- An accepted update POST receives HTTP `200`; malformed JSON or a synchronous dispatch failure receives HTTP `500`. Later handler exceptions are printed by the behavior context. No health-check or other application route is installed. +- The bot registers all supported update types. Pending updates are not explicitly dropped when the webhook is set, and the webhook remains registered after this process exits. +- `/start` works only in a private chat and replies with the configured external address, local bind host (`0.0.0.0`), and port. The displayed address does not include the optional subpath. The command is ignored in groups. + +The example does not configure a webhook `secret_token` and does not validate Telegram's secret-token header. Anyone who can reach the endpoint can submit update-shaped JSON, so protect the endpoint at the network/proxy layer or add secret-token verification before production use. + +## TLS, certificates, and networking + +The embedded server has no HTTPS connector and loads no certificate. The `setWebhook` call also uploads no public certificate. In a typical deployment: + +1. Point a public DNS name at a reverse proxy or load balancer reachable from Telegram. +2. Terminate HTTPS there with a publicly trusted certificate. +3. Forward the webhook path to this process over HTTP on its internal port. +4. Allow Telegram to reach the public listener through any firewall/NAT rules. Telegram webhook listeners use public ports `443`, `80`, `88`, or `8443`; the internal forwarded port can remain `8080`. + +Self-signed-certificate deployment is not supported by this example as written because it neither serves TLS nor passes a certificate to `setWebhook`. The external address must start with `https://`; avoid a trailing slash when also supplying a subpath, otherwise the registered URL contains a doubled slash. + +## Arguments and environment + +Create a bot with [@BotFather](https://t.me/BotFather) and obtain its token. All runtime configuration then comes from positional command-line arguments; no environment variables are read. + +- The first argument is the required bot token. +- The first argument beginning with `https://` is the required public address. +- `debug` anywhere enables formatted default KSLog output. +- The first integer-valued argument becomes the local port; otherwise it is `8080`. +- The first argument after the token that is neither the chosen address nor exactly `debug` becomes the optional subpath. A leading `/` is normalized for the public URL. + +The parser also treats a numeric port argument as a subpath candidate. Therefore `TOKEN ADDRESS 9000` registers `/9000` and listens on port `9000`; the current CLI cannot select a custom port while keeping the webhook route at `/`. Put a nonnumeric subpath before the port when both are wanted. Additional arguments are otherwise ignored. ## Launch +From the repository root, the minimal form uses `/` and port `8080`: + ```bash -../gradlew run --args="BOT_TOKEN https://sample.com it/is/subpath 8080 debug" +./gradlew :WebHooks:run --args=" https://bot.example.com" ``` -Required arguments: +Example with a subpath, custom internal port, and debug logging: -1.
