使用HttpInterceptor:可以创建一个HttpInterceptor来拦截所有的HTTP请求,并在拦截器中添加标头。可以通过实现HttpInterceptor接口来创建自定义的拦截器,并在拦截器中使用HttpRequest的clone方法来添加标头。然后,将拦截器提供给HttpClientModule的providers数组,以便在应用程序中生效。 使用自定义的HttpService:可以创建一个自定义的...
HttpInterceptor是在 Angular 4.3 引入。它提供一种方式拦截 HTTP 请求和响应,在传递他们之前转换或者处理他们。 尽管拦截器能够改变请求和响应,但是HttpRequest和HttpResponse实例属性是 只读 的,从而使它们在很大程度上不可变。 — Angular Docs 这是因为我们可能想要在某个请求第一次没成功后重试。不变性确保了拦截器...
