问题描述
I'm trying to desingn login page by angular in my java Spring Boot Aplication.
我正在尝试在我的 java Spring 引导应用程序中通过 angular 设计登录页面。 My problem is when I try login to panel page,username and password is ok and send to application by api controller and set user token correctly,but token don't set by cookeis in page, therefor panel page don't open and i have this error in inspect console:我的问题是当我尝试登录面板页面时，用户名和密码正常并通过 api controller 发送到应用程序并正确设置用户令牌，但页面中的 cookie 没有设置令牌，因此面板页面打不开，我有检查控制台中的此错误：
my login page:
我的登录页面：
