未捕获错误的原因：尝试使用断开连接的端口对象
响应请求时，我在后台页面中收到此错误 来自内容脚本。 有谁知道什么可能导致此错误？
完整堆栈跟踪：
Uncaught Error: Attempting to use a disconnected port object chrome/RendererExtensionBindings:147
chrome.Port.postMessage chrome/RendererExtensionBindings:147
chromeHidden.Port.dispatchOnConnect.connectEvent chrome/RendererExtensionBindings:89
myExtension.foo.sendResponse.state background.js:1573
db.readTransaction.tx.executeSql.paramStr background.js:1038
这仅在浏览几个小时后发生，重新加载扩展没有帮助 - 这并不是重新启动 Chrome 浏览器后的解决方案，所有内容在几个小时内恢复正常内容脚本可以继续向后台发送请求，但没有回复 从后台可以发回 有什么方法可以捕获此 Uncaught 错误并重置侦听器？
我正在使用 chrome.extension.onRequest.addListener 进行通信。在我响应之前，我查询数据库，并且在查询完成之前我不会发送任何其他响应。
谢谢， 马雷克
I am getting this error in background page when responding to request
from content script.
Does anyone know what can be causing this error?
Full stack trace:
Uncaught Error: Attempting to use a disconnected port object chrome/RendererExtensionBindings:147
chrome.Port.postMessage chrome/RendererExtensionBindings:147
chromeHidden.Port.dispatchOnConnect.connectEvent chrome/RendererExtensionBindings:89
myExtension.foo.sendResponse.state background.js:1573
db.readTransaction.tx.executeSql.paramStr background.js:1038
This only happens after a couple of hours of browsing reloading extension is not helping - not that it would be a solution after restarting chrome browser all gets back to normal for couple of hours content script can keep sending request to background but NO response
from background can be sent back Is there any way I could catch this Uncaught error and reset the listener?
I am using chrome.extension.onRequest.addListener for my communication. Before I respond I query DB and I do not send any other response before query is finished.
Thanks,
Marek

然而，就我而言，我需要向 chrome.runtime.sendMessage(msg, responseCallbackMissingHere) 提供
sendResponse函数，这将为您提供“尝试使用断开的端口对象”错误。In my case, however, I needed to provide the
sendResponsefunction to thechrome.runtime.sendMessage(msg, responseCallbackMissingHere), which will give you the "Attempting to use a disconnected port object" error.这是当连接关闭时引起的。例如，如果您打开一个注入了
content_script的选项卡，它会打开一个连接，关闭该选项卡，然后background_page尝试传递消息。它将失败，因为选项卡不再处于活动状态以接收消息。在您的情况下，我猜测当选项卡关闭并打开新选项卡时，您正在尝试使用旧的
tabId发布消息，而不是创建与新选项卡的新连接。我建议再次阅读长期连接部分。This is caused when a connection get closed. For example if you open a tab that has the
content_scriptinjected, it opens a connection, the tab is closed, and then thebackground_pagetries to pass a message. It will fail because the tab is no longer active to receive the message.In your case I would guess that as tabs close and new tabs open you are attempting to post messages with the old
tabIdinstead of creating a new connection to the new tab. I would recommend reading through the long-lived connections section again.
