Angular 9 SSR 刷新/重新加载

Question

I have the following problem with Angular and SSR . I use angular 9 . Everything works fine but when I click F5 the first thing which I see is the login page of my application and after that I see the page I'm on. I built the application with angular 8 and everything worked fine. Now I decided to migrate to the next version.

Any suggestion?

Answer 1

这是您的令牌的问题，您可能使用 localstorage 来存储令牌，而您的后端将无法从中获取令牌，因此它首先显示登录屏幕，然后在有角度的一侧提供实际页面，您需要使用 cookie 而不是 localstorage 来解决这个问题，或者更容易使用加载器，直到平台浏览器检测完成，其余的事情将以相同的方式工作。

I have the same issue too.

So, I try to remove and add an angular universal again. It shows that some structures has changed.

And also, I'm not sure about how Ivy work with SSR so I disabled it by adding an option in tsconfig.app.json followed this https://v9.angular.io/guide/ivy

And then it works.
