Exchange server 一段时间后未收到EWS流通知
我对EWS中的流媒体事件有一个奇怪的问题 我已使用此处提到的所需Cookie订阅了一组邮箱: 在收到通知一段时间后,他们突然停下来(通常在40分钟-1小时后) 我试着用EWS跟踪调试它,发现“心跳”消息 不再接收exchange server定期发送的邮件,例如:Exchange server 一段时间后未收到EWS流通知,exchange-server,exchangewebservices,office365api,Exchange Server,Exchangewebservices,Office365api,我对EWS中的流媒体事件有一个奇怪的问题 我已使用此处提到的所需Cookie订阅了一组邮箱: 在收到通知一段时间后,他们突然停下来(通常在40分钟-1小时后) 我试着用EWS跟踪调试它,发现“心跳”消息 不再接收exchange server定期发送的邮件,例如: <Envelope xmlns="http://schemas.xmlsoap.org/soap/envelope/"> <soap11:Header xmlns:soap11="http://schemas.xm

StreamingSubscriptionConnection的生存期为1-30,因此在生存期结束后,最小流打开连接,引发事件并关闭连接 你找到解决问题的方法了吗?在我调查了这个问题之后-看起来微软不时会失去订阅(至少推送方法就是这样),所以我的解决方案是为hearbeat消息设置一个拦截器,然后,如果在某个时间间隔内没有消息,则使用非流式版本的通知会观察到重新订阅名称问题。心跳会在一段时间后停止,或者在触发另一个事件时停止。真是笨手笨脚。sborpo的解决方案似乎是唯一的出路
