我已从该特定路由中删除了AuthGuard，但抛出此错误。知道如何解决这个问题吗？

Answer 1

拦截器是造成问题的一种。因为它会拦截所有http调用，并在其后注入令牌。

intercept( req: HttpRequest<any>, next: HttpHandler ): Observable<HttpEvent<any>> { 
   const authToken = this.authService.getToken(); 
   const authRequest = req.clone({ 
      headers: req.headers.set("Authorization", "Bearer " + authToken) 
   }); 

   return next.handle(authRequest); 
}

如您所见。它从服务获取令牌，然后将承载令牌注入标头中，然后再添加。

发生这种情况是因为您试图获取注销时不存在的令牌（在此行中）：

const authToken = this.authService.getToken();

解决方案？将if添加到以下类型的语句中：

const authRequest = authToken ? req.clone({ ..what you got }) : req;

如果这不起作用，我们将开始调试您的服务（authService），了解getToken的作用。否则，这应该起作用。

错误InvalidTokenError：指定了无效的令牌
