当Http请求时,角度拦截器未在头中设置令牌

我不知道出了什么事,我在网上到处查了一下,看起来和以前一样,但我发现了这个问题:

我使用带有角度拦截器的HttpClient向setHeader请求我的角度应用程序,因为我的Java Rest API使用JWT进行身份验证,并且需要在header中使用一个令牌,这样它将获取并验证用户请求,因为角度拦截器工作不正常。我在Java端得到一个空标记,并得到一个错误。请帮帮我。

最后,我发现它可能是spring安全性的问题,因为我调试后发现,option request all filter和它的dont have header所以它的showing token和throw异常 如果选项方法请求绕过并允许,则可能是我的问题将解决
