Question

我刚在项目中更新了jquery.signalR 更新后，信号灯不再工作。
我启用了日志记录，如下所示：

  $.connection.hub.logging = true;

以下是我的siganlR日志

问题是什么？

修改我的信号器很少连接，但大部分时间都发生错误

Answer 1

您的问题很可能是此处报告的错误https://github.com/SignalR/SignalR/issues/3116

我有同样的问题，我认为2.1是一个糟糕的版本。我最终回滚到2.0.3

Answer 2

这是一个错误。

通过更新到SignalR 2.1.1来解决问题

更新到2.1后，SignalR无法工作？
