Question

我正在运行Autobahn Python 0.9.3-3并且遇到一个奇怪的错误，我无法解决原因。这似乎只发生在较新的Autobahn Python客户端上。有什么想法吗？

我怀疑将Autobahn升级到0.10.x系列会解决这个问题，但不幸的是，有一些向后不兼容的更改似乎无法快速解决。

Answer 1

这是服务器中的一个错误，它似乎接受任意＆＃34;功能＆＃34;并将它们用作参数。这些新功能可能是在0.9.3版本之后的某个时间推出的。

如果有人遇到同样的问题，我会{0.9}支持created a patch。

另外，如果你对一个问题进行投票，那么解释你为什么这样做会很好，所以我可以在将来改进提问。

Autobahn Python 0.9.3-3引发与＆＃34; subscription_revocation＆＃34;相关的异常。
