I use this lib connect binance,2022.10.18 find this question。And then insert some code then can Bypass the problem。 dial.go ->verifyServerExtensions() ```go for _, p := range ext.params { switch p { case "client_no_context_takeover": copts.clientNoContextTakeover = true continue case "server_no_context_takeover": copts.serverNoContextTakeover = true continue } //add code if strings.HasPrefix(p, "server_max_window_bits") { fmt.Println("server_max_window_bits:", p) continue } return nil, fmt.Errorf("unsupported permessage-deflate parameter: %q", p) } ``` 我在使用此包连接binance币安时,最近出现标题的错误,然后我尝试在websocket包的dial.go文件的verifyServerExtensions()函数中添加了兼容server_max_window_bits字段的代码,然后就能使用了。我看文档这字段功能好像是压缩之类的功能,不确定是否后续会出现新问题. 抱歉,英文太菜了。
