# python-telegram-bot echo demo
|
|
|
|
This demo uses the normal `python-telegram-bot` API and only swaps the Bot API
|
|
base URLs to telesrv.
|
|
|
|
```powershell
|
|
python -m pip install python-telegram-bot
|
|
$env:TELESRV_BOT_TOKEN = "<bot_id>:<secret>"
|
|
python .\cmd\bots\ptbecho\echo.py `
|
|
--base-url http://127.0.0.1:8081/bot `
|
|
--base-file-url http://127.0.0.1:8081/file/bot
|
|
```
|
|
|
|
In a group with BotFather privacy enabled, send a command such as:
|
|
|
|
```text
|
|
/ping hello from group
|
|
```
|
|
|
|
主动发送一条消息并退出：
|
|
|
|
```powershell
|
|
python .\cmd\bots\ptbecho\echo.py `
|
|
--send-only `
|
|
--send-chat-id -1000000000002 `
|
|
--send-text "hello from python-telegram-bot"
|
|
```
|
|
|
|
长轮询 echo 启动后立即主动发送一条消息：
|
|
|
|
```powershell
|
|
python .\cmd\bots\ptbecho\echo.py `
|
|
--send-chat-id -1000000000002 `
|
|
--send-text "ptbecho is online"
|
|
```
|
|
|
|
可选参数：
|
|
|
|
- `--send-count N`：连续主动发送 N 条。
|
|
- `--send-interval SEC`：连续发送之间的间隔。
|
|
- `TELESRV_BOT_DEMO_CHAT_ID` / `TELESRV_BOT_DEMO_SEND_TEXT`：主动发送参数的环境变量形式。
|
|
|
|
本地超级群 chat id 使用 Bot API 形式 `-100<channel_id>`；例如 channel id 为
|
|
`2` 时是 `-1000000000002`。
|
|
|
|
Implemented telesrv Bot API surface for this demo: `getMe`, `getUpdates`,
|
|
`deleteWebhook`, `sendMessage`, and file URL configuration. The wider gateway
|
|
also has basic `sendPhoto`, `sendDocument`, `editMessageText`, `deleteMessage`,
|
|
`answerCallbackQuery`, `getFile`, and `/file/bot...` support.
