salesforce - /meta/connect 通道消息 reconnect=handshake 应该触发哪些操作？

我的应用程序订阅了一些广播 Bayeux 频道。它还通过 /meta/connect 侦听元通道以接收任何建议，以防任何连接失败。现在我的问题是我是否需要重新启动我的 Bayeux 客户端，即首先断开连接（）并再次尝试握手（）或者只有握手（）调用就足以在我得到 reconnect=handshake 作为建议时恢复连接？

请对此发表评论以获取更多信息。

这就是我为bayeux客户端设置长轮询连接的方式

现在，我通过请求标头传递的这个访问令牌具有一些刷新时间值。可以说是30分钟。这些是我所做的实现

第一次实施：

每 120 分钟我使用 client.unsubsrcibe 和 client re handshake() 但得到了非法状态异常。似乎需要断开连接才能重新握手，但不确定。因此，每 120 分钟重新启动一次客户端。但是这种方式监听器被删除可能是由于无效的 accessToken 因为我不是每 29 分钟更新一次。

第二次实施：

在每 29 分钟内，我使用重新登录获取新的连接 accessToken 以便在此自定义方法的每个回调中都将具有有效的令牌。

上述机制在一段时间后失败，并且监听器被丢弃。并从 meta/connect 获得以下信息

{"clientId":"4hi1pg62ce7bri39fnv3apg4j5ch","advice":{"reconnect":"handshake","interval":500},"channel":"/meta/connect","id":"103","error ":"403::未知客户端","成功":false}

{"clientId":"5atyxwdtyoggv4s1v3ce4dobm9u9","advice":{"reconnect":"handshake","interval":500},"channel":"/meta/connect","id":"2203","error ":"403::未知客户端","成功":false}

第三次实施：

在我的第二个实现中，我根据元/连接消息触发了 client.disconnect() 和 client.hanshake()，即每当我得到 reconnect = handshake 时，我都会断开连接并握手，它仍然可以正常工作，没有任何错误。

你能告诉我我错过了什么以及实现这些场景的正确方法应该是什么？

salesforce - Cometd/bayeux client + salesforce streaming API issue

I have my .NET client (windows service) which subscribes to Salesforce streaming API push topics.

I am able to connect to Salesforce and can get the notifications to my client. Everything is working fine, but:

When there is no activity on the channel (no changes for Salesforce object) after some time (maybe 2 hours) if I update the object, I am not receiving any notification from Salesforce.

I had tried putting listeners to log and in the logs it says below

{"clientId":"f6xo67iet55w5j7ek6ldw72nfc6","channel":"/meta/connect","id":"82","successful":true} 5/15/2018 8:12:28 PM

{"advice":{"interval":0,"reconnect":"handshake"},"channel":"/meta/connect","id":"83","error":"403::Unknown client","successful":false} 5/15/2018 8:12:28 PM

{"clientId":"hbx1v2cxebbeder11s99dqkxmasre","advice":{"interval":0,"timeout":110000,"reconnect":"retry"},"channel":"/meta/connect","id":"85","successful":true} 5/15/2018 8:12:29 PM

{"clientId":"hbx1v2cxebbeder11s99dqkxmasre","channel":"/meta/connect","id":"86","successful":true} 5/15/2018 8:14:20 PM

{"clientId":"hbx1v2cxebbeder11s99dqkxmasre","channel":"/meta/connect","id":"87","successful":true} 5/15/2018 8:16:10 PM

so as per the log, sometimes I get "403::Unknown client" but immediately after that it says again channel successful.

But as I said when I try updating the Salesforce object after 2 hours (as per log, it is in connection successful) I am not receiving any notification.

If I restart my windows service and gets the notification again.

In my client I am using cometd from - https://github.com/couchand/CometD.NET/tree/headers and for push topics subscription I am using this - https://github.com/foluis/Salesforce_PushTopics

Any help would be greatly appreciated.

salesforce - Salesforce cometD: 401::Request requires authentication

I have to subscribe to cometD Salesforce channel and hence building cometD client in python. I am using the below python library.

https://github.com/dkmadigan/python-bayeux-client

And below is the handshake response I am getting

And I am getting 401::Request requires authentication.

In the Authorization key, I have concatenated password and Access token i.e. admin@123Pi6s9Y2QVergfergregpqqY where admin@123 is the password I use to login to Salesforce.

I have been banging my head since 2 days but not able to figure out why handshake is failing. Any suggestions?
