我是 C 和 C++ 新手。我正在尝试为任何可以连接到 websocket 服务器的 C 或 C++ 中的 websocket 库找到小型工作示例。到目前为止，我已经探索了 uWebsockets、libwebsockets、websocketpp 和 boost::beast。他们似乎都没有详细的文档。我在 boost::beast 网站https://www.boost.org/doc/libs/develop/libs/beast/doc/html/beast/examples.html上找到了一些示例，但是它们也不起作用。如果我能找到一个工作示例，我可以对其进行研究以了解更多信息。
我尝试了这个命令，它连接到 yahoo 端点： wscat -c "wss://streamer.finance.yahoo.com/" -H 'Origin: https://finance.yahoo.com' 并打印随机字符串。
wscat -c "wss://streamer.finance.yahoo.com/" -H 'Origin: https://finance.yahoo.com'

我尝试过像这样的简单Python代码
from websocket import create_connection
import json
import pprint
import re
