javascript - Angular HTTP Interceptors at Module Level - Stack Overflow

admin管理员组

文章数量:1406926

I just upgraded my Angular v4.2.5 app to Angular v4.3.6 primarily to use Interceptors. It is quite an awesome feature and provides a clean way to intercept HTTP calls.

However, it seems I cannot scope interceptors at modules level. For example, I have an AppModule, and two more modules AModule and BModule. Both AModule and BModule are getting included in AppModule.

Now, is there a way in Angular 4 where I can scope interceptors at module level such that an interceptor I use for HTTP requests in AModule shouldn't be used with HTTP requests in BModule. Presently, interceptors are getting shared across all HTTP calls which was not I expected. I know providers from all modules get merged into the parent module, but is there any way to restrict such thing?

Any help is highly appreciated.

• What if you have two services that extend Http and add them to the corresponding module's providers; AService to AModule and BService to BModule, Doesn't the service only be applied to coresponding module? – Prav Commented Aug 28, 2017 at 15:13

Add a header or flag to the request from the different services? And then use this to delineate where it is from.
