我已经尝试寻找解决方案一段时间了，但我对编程仍然很陌生。我发现这篇关于类似问题的文章，但没有任何评论或解决方案对我有用，引用:
https://stackoverflow.com/questions/45541182/passport-req-logout-function-not-working
还有这个:Why is PassportJS in Node not removing session on logout
这是我的 HTML 和 JS 代码:
<!DOCTYPE html>

require("dotenv").config();

app.listen(process.env.PORT || "3000", function() {

提前致谢!
最佳答案
您应该在调用注销函数之前配置通行证。
app.use(passport.initialize());
app.use(passport.session());
应该在上述代码之后调用注销。

关于node.js - req.logout() 不是一个函数，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/72002750/
