我正在扩展。它是产品跟踪扩展。当页面加载时，在产品页面中注入一个按钮，当用户单击该按钮时，它将使用google oauth2对该用户进行身份验证。我已经完成身份验证，但是现在我无法将消息从oauth.js（popup.js）发送到content.js
我已经在这里尝试了所有相同类型的解决方案很多次，但是我认为我的问题有所不同。
有时候，消息在发送5秒钟后就会在content.js中接收到，但大多数情况下没有收到
有时，消息会在5.6秒后收到，但大多数情况下不会。消息经常显示（并非总是）
“未选中的runtime.lastError：消息端口在收到响应之前已关闭。”
身份验证api发送响应时，消息正在发送。
请看看。用户单击此按钮
https://www.screencast.com/t/TVm7OW1t2GP
打开一个弹出窗口以验证用户身份
https://www.screencast.com/t/lhEWel1OskHf
当用户通过单击按钮进行身份验证时，我正在使用api获取userinfo，然后希望将该信息发送到content.js
我已经尝试了以下链接：
sendMessage from popup to content.js not working in chrome extension
Chrome extension messaging between popup.html and content.js
