Posting a move from Python

OGS Development API Development
1

I have tried different ways to be able to post a move from python but without success so far.

Using the requests package I can use most of the REST API functionality but “games/id/move” returns 500 server error.

def make_move(token,game_id,move):
    url = 'https://online-go.com/api/v1/games/{}/move/?%s'.format(game_id,urlencode({"move":move}))
    ogs_response = requests.post(url, headers={"Authorization" : "Bearer " + token})
    return ogs_response.text

Calling this function returns

u'<h1>Server Error (500)</h1>'

Using the websocket package to connect to the real time API doesn’t work either but I cannot even see the error messages.

def on_message(ws, message):
    print "Message"

def on_error(ws, error):
    print("ERROR: ", error)

def on_close(ws):
    print("Goodbye!")
    
def on_data(ws,data,_,_2):
    print "Data"

def on_open(ws):
    print "Opening"
    print ws.send("net/ping")
    print ws.send(to_message("authenticate",data={"auth":token}))
    print ws.send(to_message("game/connect",data={'game_id': game_id, 'player_id': user_id, 'chat': 1, 'game_type': "game", 'auth':g_token}))
    print ws.send(to_message("game/move",data={"auth":g_token,"game_id":game_id,"player_id":user_id,"move":"hn"}))
    ws.send("game/move?%s"%urlencode({"auth":token,"game_id":game_id,"player_id":user_id,"move":"cq"}))

websocket.enableTrace(True)
ws = websocket.WebSocketApp("wss://online-go.com/socket.io/?transport=websocket",
                          on_message = on_message,
                          on_error = on_error,
                          on_close = on_close,
                          on_data = on_data)

ws.on_open = on_open
ws.run_forever()

This outputs:

Does anyone have a solution?

Unfortunately I don’t have a solution, in fact I can confirm you I have the same problem (error 500), using REST API via a Net.WebRequest of Visual Basic 2015.

Have you tried using the python socket io client library instead of the websocket library? Socket io is a layer on top of websockets.

With that said, my “authenticate” call in my client has more info than yours:

        socket!!.emit("authenticate", createJsonObject {
            put("player_id", uiConfig.user.id)
            put("username", uiConfig.user.username)
            put("auth", uiConfig.chat_auth)
        })

I’m not sure if all those fields are necessary. When I was creating my client I mostly looked at the network trace and did what the web site did.

Hi @nathanj439 thanks for your help. I have tried socketio-client but the problem is that there is no way to use transport = websocket for the first message, it uses xhr-polling and then upgrades to websocket, which is not supported by the server.

I’ll try adding this information and see what happens, but my main problem is that I don’t understand what websocket does because of these messages:

send: '\x81\x88\x061jYhT\x1evvX\x04>'

I think there is some kind of a double encoding problem that I haven’t been able to solve so far.

I do not know how to look at the network trace, I will research that as that seems very useful.
