我为 crud 任务创建了通用服务，该服务通过 DI（依赖注入）使用 HttpClient，但我需要在服务的构造函数中通知另一个值，如何实现？
因为当我在我的类的构造函数中定义它将使用 DI 使用 CRUD 服务时，无法将参数传递给构造函数
下面是服务
import { Injectable } from "@angular/core";
import { HttpClient } from "@angular/common/http";
import { CrudInterface } from "@app/core/crud.interface";
import { environment } from "@env/environment";
import { Observable } from "rxjs/Observable";
@Injectable()
export class CRUD<T> implements CrudInterface<T>{
endpoint: string;
constructor(private http: HttpClient, routeDir: string){
this.endpoint = `${environment.endpoint}/${routeDir}`;
}
getAll(): Observable<T[]> {
return this.http.get<T[]>(`${this.endpoint}`);
}
get(id: number): Observable<T> {
return this.http.get<T>(`${this.endpoint}/${id}`);
}
create(object: T): Observable<T> {
return this.http.post<T>(`${this.endpoint}`, object);
}
update(object: …
