# TelegramBotAPI
|
|
|
|
[ ](https://bintray.com/insanusmokrassar/StandardRepository/TelegramBotAPI/_latestVersion)
|
|
[](https://jenkins.insanusmokrassar.space/job/TelegramBotAPI_master__publishing/)
|
|
|
|
## What is it?
|
|
|
|
It is one more project which wish to be useful and full Telegram Bots API bridge for Kotlin. Most part of some specific
|
|
solves or unuseful moments are describing by official [Telegram Bot API](https://core.telegram.org/bots/api).
|
|
|
|
## Compatibility
|
|
|
|
This version compatible with [July 2018 update of TelegramBotAPI](https://core.telegram.org/bots/api#july-26-2018). That means that
|
|
most part of API has been implemented (according to last [August 2018 update of TelegramBotAPI](https://core.telegram.org/bots/api#august-27-2018))
|
|
except the Passport API which will be included as soon as possible. All included and supported API
|
|
can be found on [wiki](https://github.com/InsanusMokrassar/TelegramBotAPI/wiki/Included-API).
|
|
|
|
## How to implement library?
|
|
|
|
Common ways to implement this library are presented here. In some cases it will require additional steps
|
|
like inserting of additional libraries (like `kotlin stdlib`). In the examples will be used variable
|
|
`telegrambotapi.version`, which must be set up by developer. Available versions are presented on
|
|
[bintray](https://bintray.com/insanusmokrassar/StandardRepository/TelegramBotAPI), next version is last published:
|
|
|
|
[ ](https://bintray.com/insanusmokrassar/StandardRepository/TelegramBotAPI/_latestVersion)
|
|
|
|
### Maven
|
|
|
|
```xml
|
|
<dependency>
|
|
<groupId>com.github.insanusmokrassar</groupId>
|
|
<artifactId>TelegramBotAPI</artifactId>
|
|
<version>${telegrambotapi.version}</version>
|
|
</dependency>
|
|
```
|
|
|
|
### Gradle
|
|
|
|
```groovy
|
|
implementation "com.github.insanusmokrassar:TelegramBotAPI:${telegrambotapi.version}"
|
|
```
|
|
|
|
### Gradle (old)
|
|
|
|
```groovy
|
|
compile "com.github.insanusmokrassar:TelegramBotAPI:${telegrambotapi.version}"
|
|
```
|
|
|
|
## How to work with library?
|
|
|
|
By default in any documentation will be meaning that you have variable in scope with names
|
|
|
|
| Name of variable | Description | Where to get? (Examples) |
|
|
|:----------------:|:-----------:|:------------------------:|
|
|
| executor | [RequestsExecutor](src/main/kotlin/com/github/insanusmokrassar/TelegramBotAPI/bot/RequestsExecutor.kt) | [Ktor RequestExecutor realisation](src/main/kotlin/com/github/insanusmokrassar/TelegramBotAPI/bot/Ktor/KtorRequestsExecutor.kt) |
|
|
|
|
## Requests Examples
|
|
|
|
### Get Me
|
|
|
|
```kotlin
|
|
executor.execute(GetMe())
|
|
```
|
|
|
|
As a result you will receive `User` object. This object used as is now (as in API documentation), but it is possible
|
|
that this class will be renamed to `RawUser` and you will be able to get real realisation of this object like `Bot` (in
|
|
cases when `isBot` == `true`) or `User` (otherwise)
|
|
|
|
## Getting updates
|
|
|
|
In this library currently realised two ways to get updates from telegram:
|
|
|
|
* Polling - in this case bot will request updates from time to time (you can set up delay between requests)
|
|
* Webhook via reverse proxy or something like this
|
|
|
|
### Updates filters
|
|
|
|
Currently webhook method contains `UpdatesFilter` as necessary argument for getting updates.
|
|
`UpdatesFilter` will sort updates and throw their into different callbacks. Currently supporting
|
|
separate getting updates for media groups - they are accumulating with debounce in one second
|
|
(for being sure that all objects of media group was received).
|
|
|
|
Updates polling also support `UpdatesFilter` but you must not use it and can get updates directly
|
|
in `UpdateReceiver`, which you will provide to `startGettingOfUpdates` method
|
|
|
|
### Webhook set up
|
|
|
|
If you wish to use webhook method, you will need:
|
|
|
|
* White IP - your IP address or host, which available for calling. [TelegramBotAPI](https://core.telegram.org/bots/api#setwebhook)
|
|
recommend to use some unique address for each bot which you are using
|
|
* SSL certificate. Usually you can obtain the certificate using your domain provider, [Let'sEncrypt](https://letsencrypt.org/) or [create it](https://core.telegram.org/bots/self-signed)
|
|
* Nginx or something like this
|
|
|
|
Template for Nginx server config you can find in [this gist](https://gist.github.com/InsanusMokrassar/fcc6e09cebd07e46e8f0fdec234750c4#file-nginxssl-conf).
|
|
|
|
For webhook you can provide `File` with public part of certificate, `URL` where bot will be available and inner `PORT` which
|
|
will be used to start receiving of updates. Actually, you can skip passing of `File` when you have something like
|
|
nginx for proxy forwarding.
