你检查过你发现的脚本是否有效吗？如果是这样，那么比较脚本发送的数据包和C++程序发送的数据包。看看区别是什么。你发送了错误的数据。我从Python和Bash脚本中看到了十六进制编码的数据和base64编码的数据（请注意，这些脚本不仅仅发送字符串）。您需要发送以字符串而不是字符串编码的原始二进制数据itself@AndreyTurkin谢谢你的回复！我已经在主题中添加了api的命令。所以我必须用base64或hex将这些对象转换为原始二进制数据。我添加了一个解码器，这是我从het互联网上找到的。但是，当我使用Wireshark@andreyturkin对消息进行调查时，消息是否仍然不同？这不是发送
