我有看到你们公众号发的“自动删除消息功能的实现” 这个自动删除的逻辑能解释下吗？ 服务端我调用了接口传了expireDuration 设为1000，我理解的是：1秒后消息过期，可是我客户端已经杀死后台的情况下，再进入app还是显示了这条消息。 我客户端在线，再发一条，消息一秒后也依然存在。 我客户端协议栈已经升级到12.22了 服务端的版本是： { "tags":"null", "branch":"1c152b8486fb582ca75f87734b89f4a685b47b5e", "dirty":"null", "remoteOriginUrl":"git@github.com:heavyrain2012/server_commercial.git", "commitId":"1c152b8486fb582ca75f87734b89f4a685b47b5e", "commitIdAbbrev":"1c152b8", "describe":"moli-778-g1c152b8-dirty", "describeShort":"null", "commitUserName":"heavyrian2012", "commitUserEmail":"heavyrain.lee@wildfirehat.cn", "commitMessageFull":"fix get valid session error\n", "commitMessageShort":"fix get valid session error", "commitTime":"20230525113258", "nodeIds":"1 ", "closestTagName":"null", "closestTagCommitCount":"null", "buildUserName":"Unknown", "buildUserEmail":"Unknown", "buildTime":"20230526115457", "buildHost":"null", "buildVersion":"null", "verified":true, "currentNode":1, "runTime":5898826 }
