README
According to [the doc](https://docs.nestjs.com/exception-filters#exception-filters-1),
if using `app.useGlobalFilters(new HttpExceptionFilter());` to register the filter, the filter cannot be injected directly, but:
```ts
import { Module } from '@nestjs/common';
import { APP_FILTER } from '@nestjs/core';
@Module({
providers: [
{
provide: APP_FILTER,
useClass: HttpExceptionFilter,
},
],
})
export class AppModule {}
```
however, in this repo I still can inject the filter normally:
[src/cats/cats.controller.ts](./src/cats/cats.controller.ts)
```diff
import { Controller, ForbiddenException, Get } from '@nestjs/common';
import { HttpExceptionFilter } from '../exception/http-excption.filter';
@Controller('cats')
export class CatsController {
+ constructor(private readonly filter: HttpExceptionFilter) {
+ console.log('look, the filter been injected', this.filter);
+ }
@Get()
async create() {
throw new ForbiddenException();
}
}
```
