Question

我正在尝试连接到Binance Websocket流。在their documentation之后，我使用下面的代码建立连接：

from websocket import create_connection

ws = create_connection('wss://fstream.binance.com/')

虽然运行它，但出现以下错误：

WebSocketBadStatusException: Handshake status 400 Bad Request

我在网上找不到有关此错误的任何信息。

有人知道如何解决此问题吗？

Answer 1

这一点在Binance API文档中还不清楚。

期货的基本网址为：

wss：//fstream.binance.com
wss：//fstream3.binance.com

但是，如果您仅连接到这些基本URL，则会遇到上述异常。您应该将url-string补充到

wss：//fstream.binance.com/ws
wss：//fstream3.binance.com/ws

对于现货市场和所有其他网络套接字都是相同的。始终在末尾加上“ / ws”。

您还可以开始订阅connection-url，然后看起来像下面的现货市场示例：

wss：//stream.binance.com：9443 / ws / btcusdt @ aggTrade

（但是我认为只连接“ / ws”，然后按照文档中的说明进行实时订阅/取消订阅流是更好的方法。）

您可以安装python-binance并使用BinanceSocketManager

python -m pip安装python-binance

使用我发现的以下代码here

import time
from binance.client import Client # Import the Binance Client
from binance.websockets import BinanceSocketManager # Import the Binance Socket Manager

# Although fine for tutorial purposes, your API Keys should never be placed directly in the script like below. 
# You should use a config file (cfg or yaml) to store them and reference when needed.
PUBLIC = '<YOUR-PUBLIC-KEY>'
SECRET = '<YOUR-SECRET-KEY>'

# Instantiate a Client 
client = Client(api_key=PUBLIC, api_secret=SECRET)

# Instantiate a BinanceSocketManager, passing in the client that you instantiated
bm = BinanceSocketManager(client)

# This is our callback function. For now, it just prints messages as they come.
def handle_message(msg):
    print(msg)

# Start trade socket with 'ETHBTC' and use handle_message to.. handle the message.
conn_key = bm.start_trade_socket('ETHBTC', handle_message)
# then start the socket manager
bm.start()

# let some data flow..
time.sleep(10)

# stop the socket manager
bm.stop_socket(conn_key)

您缺少websocket connect上的路径！

看看binance api文档： https://binance-docs.github.io/apidocs/futures/en/#websocket-market-streams

python-binance不支持websocket来对期货端点进行币种化，因此您可以改用unicorn-binance-websocket-api，这是未来端点的示例： https://github.com/oliver-zehentleitner/unicorn-binance-websocket-api/blob/master/example_binance_futures.py

无法连接到Binance Websocket。我得到：WebSocketBadStatusException：握手状态400错误的请求
