HTTPXRequest¶

Bases: telegram.request.BaseRequest

Implementation of BaseRequest using the library httpx.

• connection_pool_size (int, optional) –

  Number of connections to keep in the connection pool. Defaults to 256.

  Changed in version 22.4: Set the default to 256. Stopped applying to httpx.Limits.max_keepalive_connections. Now only applies to httpx.Limits.max_connections. See Resource Limits

• read_timeout (float | None, optional) – If passed, specifies the maximum amount of time (in seconds) to wait for a response from Telegram’s server. This value is used unless a different value is passed to do_request(). Defaults to 5.

• write_timeout (float | None, optional) –

  If passed, specifies the maximum amount of time (in seconds) to wait for a write operation to complete (in terms of a network socket; i.e. POSTing a request or uploading a file). This value is used unless a different value is passed to do_request(). Defaults to 5.

  Hint

  This timeout is used for all requests except for those that upload media/files. For the latter, media_write_timeout is used.

• connect_timeout (float | None, optional) – If passed, specifies the maximum amount of time (in seconds) to wait for a connection attempt to a server to succeed. This value is used unless a different value is passed to do_request(). Defaults to 5.

• pool_timeout (float | None, optional) –

  If passed, specifies the maximum amount of time (in seconds) to wait for a connection to become available. This value is used unless a different value is passed to do_request(). Defaults to 1.

  Warning

  With a finite pool timeout, you must expect telegram.error.TimedOut exceptions to be thrown when more requests are made simultaneously than there are connections in the connection pool!

• http_version (str, optional) –

  If "2" or "2.0", HTTP/2 will be used instead of HTTP/1.1. Defaults to "1.1".

  Added in version 20.1.

  Changed in version 20.2: Reset the default version to 1.1.

  Changed in version 20.5: Accept "2" as a valid value.

• socket_options (Collection[tuple], optional) –

  Socket options to be passed to the underlying library.

  Note

  The values accepted by this parameter depend on the operating system. This is a low-level parameter and should only be used if you are familiar with these concepts.

  Added in version 20.7.

• proxy (str | httpx.Proxy | httpx.URL, optional) –

  The URL to a proxy server, a httpx.Proxy object or a httpx.URL object. For example 'http://127.0.0.1:3128' or 'socks5://127.0.0.1:3128'. Defaults to None.

  Note

  • The proxy URL can also be set via the environment variables HTTPS_PROXY or ALL_PROXY. See the docs of httpx for more info.

  • HTTPS proxies can be configured by passing a httpx.Proxy object with a corresponding ssl_context.

  • For Socks5 support, additional dependencies are required. Make sure to install PTB via pip install "python-telegram-bot[socks]" in this case.

  • Socks5 proxies can not be set via environment variables.

  Added in version 20.7.

• media_write_timeout (float | None, optional) –

  Like write_timeout, but used only for requests that upload media/files. This value is used unless a different value is passed to do_request.write_timeout of do_request(). Defaults to 20 seconds.

  Added in version 21.0.

• httpx_kwargs (dict[str, Any], optional) –

  Additional keyword arguments to be passed to the httpx.AsyncClient constructor.

  Warning

  This parameter is intended for advanced users that want to fine-tune the behavior of the underlying httpx client. The values passed here will override all the defaults set by python-telegram-bot and all other parameters passed to HTTPXRequest. The only exception is the media_write_timeout parameter, which is not passed to the client constructor. No runtime warnings will be issued about parameters that are overridden in this way.

  Added in version 21.6.
