ConnectionResetError: [WinError 10054] 远程主机强迫关闭了一个现有的连接。

发生原因：okhttp默认http请求头：Connection：keep-alive请求头，造成客户端关闭了，服务端的长连接还在保持

客户端解决：可根据实际情况，如不需要http保持长链接，给给客户端请求添加请求头："Connection","close" 即可

代码示例：

Request request = builder.url(url)
        .addHeader("Connection","close") // keep-alive 或 close
        .build();
