Running the request example on the /lol-chat/v1/me endpoint returns a string like so:

{'availability': 'chat', 'gameName': 'Natrocx', 'gameTag': 'EUW', 'icon': 715, 'id': '[email protected]', 'lastSeenOnlineTimestamp': None, 'lol': {'championId': '', 'companionId': '4008', 'gameQueueType': '', 'gameStatus': 'outOfGame', 'level': '311', 'mapId': '', 'masteryScore': '526', 'puuid': '04e3da3d-8761-5fc7-819b-e5b85923d940', 'rankedLeagueDivision': 'III', 'rankedLeagueQueue': 'RANKED_FLEX_SR', 'rankedLeagueTier': 'GOLD', 'rankedLosses': '0', 'rankedSplitRewardLevel': '2', 'rankedWins': '41', 'regalia': '{"bannerType":2,"crestType":1}', 'skinVariant': '', 'skinname': ''}, 'name': 'Natrocx', 'patchline': 'live', 'pid': '[email protected]', 'platformId': 'EUW1', 'product': 'league_of_legends', 'productName': '', 'puuid': '04e3da3d-8761-5fc7-819b-e5b85923d940', 'statusMessage': '', 'summary': '', 'summonerId': 0000000, 'time': 0}

There are multiple things wrong with this.

1. Putting strings in single quotes is illegal in JSON
2. None is not an expression in JSON

This wouldn't bother me if I wasn't trying to parse this again, which quite frankly doesn't work without a huge hassle.

Trying to run the following code...

# fired when LCU API is ready to be used

@conn.close

    print('The client have been closed!')
    await connect.stop()


# subscribe to '/lol-summoner/v1/current-summoner' endpoint for the UPDATE event
# when an update to the user happen (e.g. name change, profile icon change, level, ...) the function will be called

Hiya! I've encountered an issue that is affecting lcu-driver. It seems to have started yesterday and happens occassionally (sometimes it works, sometimes it doesn't). ;w;

Describe the bug
lcu-driver fails when attempting to start the driver with a ValueError.

To Reproduce
Steps to reproduce the behavior:

1. Install the latest version 2.1.3.
2. Install psutil 5.6.5.
3. Use minimum reproducible example code below (see Additional Context).
4. Open the League client.
5. Run Python script.
6. Encounter ValueError (only if --riotgamesapi-settings has an offending line, see Error section).

Expected behavior
Expected lcu-driver to start without encountering the ValueError.

Additional context

from lcu_driver import Connector
from lcu_driver.events.responses import WebsocketEventResponse

connector = Connector()

@connector.ready
async def connect(connection):
  print("ready")

@connector.close
async def disconnect(connection):
  print("finished")
  await connector.stop()

@connector.ws.register('/lol-summoner/v1/current-summoner', event_types=('UPDATE',))
async def update(connection, event: WebsocketEventResponse):
  print(event.data)

connector.start()

connector accidently close once loading the game, and it will reconnect later, even if I have set never close the client when gaming in the client config.

When the client closes, 'await connector.stop()' causes an infinite loop, making the 'async def disconnect(_)' repeat infinitely. I am using the normal code example from the docs:

`from lcu_driver import Connector

connector = Connector()

@connector.ready
async def connect(connection):
print('LCU API is ready to be used.')

@connector.close
async def disconnect(_):
print('The client have been closed!')
await connector.stop()

@connector.ws.register('/lol-summoner/v1/current-summoner', event_types=('UPDATE',))
async def icon_changed(connection, event):
print(f'The summoner {event.data["displayName"]} was updated.')

connector.start()`

Now some LCU API force to use http2. Requests Unable to communicate properly #

Hello, I recently tried a piece of code that was an example in the library,
The problem is that when i run the code i get the message that says that the LCU API is ready to be used then i get directly after the message that says that the client has been closed (it is not).
As you can see with the time that is displayed in the output the client opens and closes instantly.

The code

from random import randint
from datetime import datetime
from lcu_driver import Connector

connector = Connector()


# fired when LCU API is ready to be used
@connector.ready
async def connect(connection):
    print(datetime.now(), 'LCU API is ready to be used.')

# fired when League Client is closed (or disconnected from websocket)
@connector.close
async def disconnect(_):
    print(datetime.now(), 'The client have been closed!')

# starts the connector
connector.start()

Output

2022-08-14 15:10:10.715474 LCU API is ready to be used.
2022-08-14 15:10:10.716652 The client have been closed!

response = await connection.request('POST', '/lol-login/v1/session/invoke?destination=lcdsServiceProxy&method=call&args=["","teambuilder-draft","quitV2",""]')

print(await response.json())

returns:
{'body': {'body': None, 'clientId': 'nil', 'correlationId': '3954134057-197', 'destination': None, 'headers': {}, 'messageId': 'A1C5A6D0-FDCA-7F02-224D-2CDF4B030A25', 'timeToLive': 0.0, 'timestamp': 1654777177421.0}, 'typeName': 'flex.messaging.messages.AcknowledgeMessage'}

instead of dodging the lobby.

The endpoint is correct. I think something is wrong with the library

Any idea?

How to display it on tkinter or something else?

The auto json encode on the ["data"] field is not a good idea, as "data" is usually supposed to be the body.
If you have a JSON body, you should send the "json" parameter instead of data, as they are mutually exclusive.

Excerpt from aiohttp doc

json – Any json compatible python object (optional). json and data parameters could not be used at the same time.

you dont even need to parse the data field into json, as aiohttp will do it for you.

As some of the lcu-api functions require plain-text / form encoded data, the data field should be passed along and not parsed.

Suggestion

Remove 'data'-autoparsing on the request and adjust the pydoc to the following.

Send JSON body data via the **json** keyword argument. The **data** keyword can be used for form based data. 
Both keywords (json and data) are mutually exclusive. Make sure to only send one.

connector.stop() does not work, well it works with that pull requests but not when the League client isnt open

I'm trying out the following example: https://lcu-driver.readthedocs.io/en/latest/examples.html#change-summoner-icon

It updates my summoner-icon but the script immediately ends while the client is still open. Is this expected behavior?

Hi,
Im trying to create a websocket connection but it does not seem to do anything... How do I know if an endpoint has a websocket connection?

@connector.ws.register('/lol-game-client-chat/v1/muted-summoners', event_types=('UPDATE',))
async def muted_summoner(connection, event):
    print(f'The summoner {event.data["displayName"]} was muted.')

Hi,
it seems like the connection.request is returning _RequestContextManager instead of the proper ClientResponse.

I'm testing it on the example code from docs:

from lcu_driver import Connector

connector = Connector()

@connector.ready
async def connect(connection):
    summoner = await connection.request('get', '/lol-summoner/v1/current-summoner')
    print(await summoner.json())

connector.start()

I am using the latest lcu-driver from github. Pipfile:

[[source]]
url = "https://pypi.org/simple"
verify_ssl = true
name = "pypi"

[packages]
lcu-driver = {editable = true, git = "https://github.com/sousa-andre/lcu-driver.git"}

[dev-packages]

[requires]
python_version = "3.10"

I'm running a script to launch League Client and some python script to fetch some data from it with the help of lcu-driver(Thank you for your great work and sharing).

This is being done in a cheap remote server, to be specifically, an Azure B1S instance(1vCPU, 1GB RAM).

Probably because of its poor performance(it takes almost 5 mins to finish loading from graphical perspective), even when connecting to it when ready() is fired, it's giving error like this

aiohttp.client_exceptions.ClientConnectorError: Cannot connect to host 127.0.0.1:50763 ssl:False [The remote computer refused the network connection]

I tried to solve this by just waiting for 5mins after the ready() is fired. But it's causing another problem, the connection seems to be timed out so an
ConnectionResetError: [WinError 10054] An existing connection was forcibly closed by the remote host
is raised by CHANCE. Sometimes it works.

I could possibly fix this by using two connectors one just to detect the launch of League Client(by ready()) and sleep 5mins, after that just close and use another connector to my job. Don't know if it will workout.

But I guess ready() is not working as expected(it's not ready yet!). Or is it?
So a fix to ready() would help very much. Or maybe I'm miss using the driver, is there anything I should try?

Should the library have an option to unregister an event from the connector or is the locals attribute enough? With the current architeture unregistering events from the connector instance might cause problems when handling events from multiple clients.

The documentation should be updated.

• More code examples must be added to the documentation.
• The documentation is not very explicit and simple to understand as it should be. A more clear language is required.
• The documentation should explain how to extend the BaseConnector in order to create a more customized connector class.

Some endpoints return error code, but in browser they can return data, such as /lol-mactch-history/v3/matchlist/account/{accountId}.
I'm confusing...

Hi there.
I copied one of the examples, but when it is supposed to print summoner displayname etc, nothing is getting printed. The same happens with lockfile.
Am I stupid or did I just miss something?
