Signalr 从Visual Studio运行一段时间后，信号器连接将自动停止
我有一个网页，使用SignalR在JqGrid中显示最新的数据集。每当修改数据时，所有连接的客户端都会使用更新的数据重新加载jQGrid 一切正常，但我注意到页面在一段时间后（即大约一分钟后）停止刷新数据。浏览器中的状态栏几乎每秒都在快速运行。如果我通过执行F5刷新页面，那么grid将开始刷新数据，但一段时间后会停止 此外，我还意识到，无论我在ReconnectionTimeout参数中设置了什么值，我的网格都只会刷新该时间段的数据，然后停止 我的出发点如下：Signalr 从Visual Studio运行一段时间后，信号器连接将自动停止,signalr,Signalr,我有一个网页，使用SignalR在JqGrid中显示最新的数据集。每当修改数据时，所有连接的客户端都会使用更新的数据重新加载jQGrid 一切正常，但我注意到页面在一段时间后（即大约一分钟后）停止刷新数据。浏览器中的状态栏几乎每秒都在快速运行。如果我通过执行F5刷新页面，那么grid将开始刷新数据，但一段时间后会停止 此外，我还意识到，无论我在ReconnectionTimeout参数中设置了什么值，我的网格都只会刷新该时间段的数据，然后停止 我的出发点如下： var config = AspN

Signal在指定的重新连接超时后自动重新连接，默认值为110秒。如果连接完全停止，则会出现其他问题，信号器将永远重试。您能否运行fiddler并尝试重现问题（顺便说一句，打开流媒体模式）？这很可能是您网络中的某个网络设备或IE8信号器中的一个错误。它会与其他浏览器重新编程吗？您好@dflower，当我从Visual Studio运行时，这个问题正在发生。从IIS它工作得很好。我已经在各种浏览器上测试过它，如IE8/9、Firefox、Chrome，当从VS运行时，所有浏览器都会出现错误。我使用fiddler跟踪它，这表明SignalR遇到了异常。我正在用小提琴手的堆栈跟踪更新我的问题。请提出建议。您使用的是IIS Express还是Visual Studio开发服务器（Cassini）？@Andy，我使用的是Cassini（带SP1的VS2010）。这就是遇到“对象移动到此处错误”的地方。在iis7.5上，它工作正常。请建议..您可以右键单击项目并选择“使用IIS Express”吗？在指定的重新连接超时后，SignalR将自动重新连接，默认值为110秒。如果连接完全停止，则会出现其他问题，信号器将永远重试。您能否运行fiddler并尝试重现问题（顺便说一句，打开流媒体模式）？这很可能是您网络中的某个网络设备或IE8信号器中的一个错误。它会与其他浏览器重新编程吗？您好@dflower，当我从Visual Studio运行时，这个问题正在发生。从IIS它工作得很好。我已经在各种浏览器上测试过它，如IE8/9、Firefox、Chrome，当从VS运行时，所有浏览器都会出现错误。我使用fiddler跟踪它，这表明SignalR遇到了异常。我正在用小提琴手的堆栈跟踪更新我的问题。请提出建议。您使用的是IIS Express还是Visual Studio开发服务器（Cassini）？@Andy，我使用的是Cassini（带SP1的VS2010）。这就是遇到“对象移动到此处错误”的地方。在iis7.5上，它工作正常。请建议..您可以右键单击您的项目并选择“使用IIS Express”吗？
