bfportal-grpc 0.1.3

bf2042 portal web grpc as python package

Battlefield Portal web-grpc

This npm package can be used to directly call the https://portal.battlefield.com/ api. we're making this public since you can read the javascript of the website and figure this out yourself easily anyway, but we want to make sure only 1 github repo has to be kept in sync with the api and the rest that uses it just has to update a package and a few code changes to still have it work.

example

import { CommunityGamesClient, communitygames } from 'bfportal-grpc';

const communityGames = new CommunityGamesClient('https://kingston-prod-wgw-envoy.ops.dice.se', null);
const metadata = {
    'x-dice-tenancy': 'prod_default-prod_default-kingston-common',
    'x-gateway-session-id': sessionId,
    'x-grpc-web': '1',
    'x-user-agent': 'grpc-web-javascript/0.1',
}

const request = new communitygames.GetPlaygroundRequest();
request.setPlaygroundid(testPlayground);
const response = await communityGames.getPlayground(request, metadata);
const modRules = response.getPlayground()?.getOriginalplayground()?.getModrules()?.getCompatiblerules()?.getRules();
if (modRules instanceof Uint8Array) {
    console.log(new TextDecoder().decode(modRules))
}
const playgroundName = response.getPlayground()?.getOriginalplayground()?.getName();

the proto files are accessable directly via "node_modules/bfportal-grpc/proto/communitygames.proto" to for example decode to json:

// use reponse from previous example
const root = await load("node_modules/bfportal-grpc/proto/communitygames.proto");
const AwesomeMessage = root.lookupType("web.communitygames.PlaygroundInfoResponse");
const decoded = AwesomeMessage.decode(response.serializeBinary());
const json_str = JSON.stringify(decoded, null, 4);

non-async example

import { CommunityGamesClient, communitygames } from 'bfportal-grpc';

const communityGames = new CommunityGamesClient('https://kingston-prod-wgw-envoy.ops.dice.se', null);
const metadata = {
    'x-dice-tenancy': 'prod_default-prod_default-kingston-common',
    'x-gateway-session-id': sessionId,
    'x-grpc-web': '1',
    'x-user-agent': 'grpc-web-javascript/0.1',
}

const request = new communitygames.GetPlaygroundRequest();
request.setPlaygroundid("bbe433c0-13fa-11ed-bc32-24a8c2c0764e");
const call = communityGames.getPlayground(request, metadata,
  (_err: grpcWeb.Error, response: communitygames.PlaygroundInfoResponse) => {
    // console.log("err:", _err)
    var modRules = response.getPlayground()?.getOriginalplayground()?.getModrules()?.getCompatiblerules()?.getRules();
    if (modRules instanceof Uint8Array) {
        console.log(new TextDecoder().decode(modRules))
    }

    load("node_modules/bfportal-grpc/proto/communitygames.proto", function(err, root) {
      if (err)
        throw err;
      if (root == undefined) 
        return

      const AwesomeMessage = root.lookupType("web.communitygames.PlaygroundInfoResponse");

      let decoded = AwesomeMessage.decode(response.serializeBinary());
      fs.writeFile("test.json", JSON.stringify(decoded, null, 4), function(err: any) {
        if (err) {
            console.log(err);
        }
      });
    })
});

python

for python you can use the 'sonora' package to do grpc-web

import asyncio
import sonora.aio
from bfportal_grpc import communitygames_pb2, communitygames_pb2_grpc, access_token, authentication_pb2, authentication_pb2_grpc

async def main():
    cookie = access_token.Cookie(sid="", remid="")
    token = await access_token.getBf2042GatewaySession(cookie)
    
    async with sonora.aio.insecure_web_channel(
        f"https://kingston-prod-wgw-envoy.ops.dice.se"
    ) as channel:
        stub = authentication_pb2_grpc.AuthenticationStub(channel)
        auth_response: authentication_pb2.AuthResponse = await stub.viaAuthCode(authentication_pb2.AuthRequest(platform=1, authCode=token, redirectUri='https://portal.battlefield.com/'), metadata=(
            ('x-dice-tenancy', 'prod_default-prod_default-kingston-common'),
            ('x-gateway-session-id', 'web-c6b312c9-2520-4fde-958d-60ae71840a65'),
            ('x-grpc-web', '1'),
            ('x-user-agent', 'grpc-web-javascript/0.1')
        ))
        
        stub = communitygames_pb2_grpc.CommunityGamesStub(channel)
        response: communitygames_pb2.PlaygroundInfoResponse = await stub.getPlayground(communitygames_pb2.GetPlaygroundRequest(playgroundId="10992a10-461a-11ec-8de0-d9f491f92236"), metadata=(
            ('x-dice-tenancy', 'prod_default-prod_default-kingston-common'),
            ('x-gateway-session-id', auth_response.sessionId),
            ('x-grpc-web', '1'),
            ('x-user-agent', 'grpc-web-javascript/0.1')
        ))
        
        print(response.playground.originalPlayground.name)
            
if __name__ == "__main__":
    asyncio.run(main())

current build method from proto to javascript via python

needs proto-compile, which can be installed with: pip3 install proto-compile

and build with: proto-compile --clear-output-dirs --verbosity=1 ./proto ./src/proto grpc-web --grpc_web_out_options="import_style=typescript,mode=grpcweb"

building for python requires grpcio-tools, which can be installed with: pip3 install grpcio-tools

and build with: python3 -m grpc_tools.protoc -I. --python_out=./grpc-python --grpc_python_out=./grpc-python ./proto/communitygames.proto ./proto/localization.proto ./proto/authentication.proto ./proto/reporting.proto

Pushing your changes

package versions can be made with npm run build and npm version patch git push --tags origin main to release. for python patch with npm run build:python, npm run python:setimports and poetry build.
