pybfbc2stats

Python 🐍 library for retrieving statistics of Battlefield: Bad Company 2 players. Possible thanks to previous work by Luigi Auriemma and nemo.

Features

• lookup players/personas by id or name
• search for players/personas by name (with wildcard support)
• retrieve all available player statistics
• retrieve player dogtag records
• retrieve player leaderboards
• retrieve server list
• retrieve individual game server's details for (including player list)
• support for all platforms (PC, Xbox 360, PS3)
• full support for async Python

Installation

Simply install the package via pip.

$ pip install pybfbc2stats

Usage

TLS 1.0

The FESL backend only supports TSL 1.0. So, you can only use this library in an environment that allows Python to use TLS 1.0. The easiest and least intrusive way to enable TLS 1.0 support is to set an OPENSSL_CONF environment variable that contains the absolute path to the included openssl.cnf. On Linux, you can set it by running this in the project directory:

export OPENSSL_CONF=$(realpath openssl.cnf)

Basic example

The following examples show how to find a player/persona by name and retrieve their stats using the default as well as the async client.

Retrieve stats using the default FESL client

fromurllib.parseimportquotefrompybfbc2statsimportFeslClient, Platform, Namespacedefmain():
withFeslClient('ea_account_name', 'ea_account_password', Platform.pc) asclient:
quoted_name=quote('Krut0r')
persona=client.lookup_username(quoted_name, Namespace.pc)
stats=client.get_stats(int(persona['userId']))
print(stats)
if__name__=='__main__':
main()

Retrieve stats using the async FESL client

importasynciofromurllib.parseimportquotefrompybfbc2statsimportAsyncFeslClient, Platform, Namespaceasyncdefmain():
asyncwithAsyncFeslClient('ea_account_name', 'ea_account_password', Platform.pc) asclient:
quoted_name=quote('Krut0r')
persona=awaitclient.lookup_username(quoted_name, Namespace.pc)
stats=awaitclient.get_stats(int(persona['userId']))
print(stats)
if__name__=='__main__':
asyncio.run(main())

Retrieve the server list using the default theater client

frompybfbc2statsimportFeslClient, TheaterClient, Platformdefmain():
# First, get theater details and login key (lkey) from FESLwithFeslClient('ea_account_name', 'ea_account_password', Platform.ps3) asfeslClient:
theater_hostname, theater_port=feslClient.get_theater_details()
lkey=feslClient.get_lkey()
# Now use the theater client to get the server listwithTheaterClient(theater_hostname, theater_port, lkey, Platform.ps3) astheaterClient:
lobbies=theaterClient.get_lobbies()
servers= []
forlobbyinlobbies:
lobby_servers=theaterClient.get_servers(int(lobby['LID']))
servers.extend(lobby_servers)
print(servers)
if__name__=='__main__':
main()

Retrieve the server list using the async theater client

Client methods

Both the default and the async clients offer the same methods with the same signatures.

[Async]FeslClient(username, password, platform, timeout)

Create a new [Async]FeslClient instance.

Note: The account has to be valid for Bad Company 2. If your account does not work, you can create a new one using ealist: .\ealist.exe -A -a [username] [password] bfbc2-pc (the created account will work for all platforms).

Arguments

username	str	Required
password	str	Required
platform	Platform	Required	One of: Platform.pc, Platform.ps3 (Xbox 360 is not yet supported)
timeout	float	Optional	How long to wait for data before raising a timeout exception (timeout is applied per socket operation, meaning the timeout is applied to each read from/write to the underlying connection to the FESL backend)

---

[Async]FeslClient.hello()

Send the initial "hello" packet to the FESL server.

---

[Async]FeslClient.memcheck()

Send the response to the FESL server's "memcheck" challenge.

---

[Async]FeslClient.login()

Send the login details to the FESL server.

---

[Async]FeslClient.get_lkey()

Get the login key (lkey) used to authenticate on theater backend.

---

[Async]FeslClient.get_theater_details()

Get the hostname and port of the theater backend for the client's platform.

---

[Async]FeslClient.lookup_usernames(usernames, namespace)

Lookup a list of url encoded/quoted usernames and return any matching personas (only exact name matches are returned).

Note: Since this method accepts a namespace argument, it can lookup usernames in any namespace (on any platform), regardless of which Platform was used to create the client instance.
