【中文标题】Poloniex 新的 Websocket API【英文标题】:Poloniex New Websocket API 【发布时间】:2018-08-29 07:33:02 【问题描述】:我正在尝试使用new websocket API with Poloniex。 Wamp 现在已被弃用,关于如何对实时公共数据(如音量等)进行简单调用的信息非常少。
我发现这段代码似乎实现了这个套接字,但出现在比特流中。当我运行代码时,它会很好地调用标头并获得响应标头,并且似乎可以发送和接收数据,但随后会关闭套接字。如何订阅音量通道并解码流数据?
import websocket
import threading
import time
import json
from threading import Thread
def on_message(ws, message):
print(message)
def on_error(ws, error):
print(error)
def on_close(ws):
print("### closed ###")
def on_open(ws):
print("ON OPEN")
def run(*args):
ws.send(json.dumps('command':'subscribe','channel':1003))
while True:
time.sleep(1)
ws.close()
print("thread terminating...")
threading.Thread(target=run).start()
if __name__ == "__main__":
websocket.enableTrace(True)
ws = websocket.WebSocketApp("wss://api2.poloniex.com/",
on_message = on_message,
on_error = on_error,
on_close = on_close)
ws.on_open = on_open
ws.run_forever()
Am expecting a streaming connection to volume data but get this:
ON OPEN
send: b"\x81\xa9.)\x1d\xb8U\x0b~\xd7CD|\xd6J\x0b'\x98\x0cZh\xda]Jo\xd1LL?\x94\x0e\x0b~\xd0OGs\xddB\x0b'\x98\x1f\x19-\x8bS"
[1003,1]
unorderable types: float() > NoneType()
send: b'\x88\x82fWPGe\xbf'
### closed ###

【参考方案1】:奇怪,因为我无法重现你的错误,试试这个:
import websocket
import threading
import time
import json
from threading import Thread
def on_message(ws, message):
json_msg = json.loads(message)
channel_id = int(json_msg[0])
if (channel_id==1003) and len(json_msg)>2:
print("volume update")
print(json_msg[2][2])
def on_error(ws, error):
print(error)
def on_close(ws):
print("### closed ###")
def on_open(ws):
print("ON OPEN")
def run(*args):
ws.send(json.dumps('command':'subscribe','channel':"1003"))
threading.Thread(target=run).start()
if __name__ == "__main__":
websocket.enableTrace(True)
ws = websocket.WebSocketApp("wss://api2.poloniex.com/",
on_message = on_message,
on_error = on_error,
on_close = on_close)
ws.on_open = on_open
ws.run_forever()
哪个给你:
[...]
ON OPEN
send: '\x81\xab\xc0\xe6~#\xbb\xc4\x1dL\xad\x8b\x1fM\xa4\xc4D\x03\xe2\x95\x0bA\xb3\x85\x0cJ\xa2\x83\\\x0f\xe0\xc4\x1dK\xa1\x88\x10F\xac\xc4D\x03\xe2\xd7N\x13\xf3\xc4\x03'
