Looking for a service "code" that can centrally manage the interface?!

1. At first, I wrote the interface in each component.ts

tell me what I'm doing. I don't know if it meets your requirements.
I'm writing interface url into a class:

export class ServicePath {
    public static SHOPLIST = 'xxx.xxx';
}

the http request is only made in the service, which is the same as the case on the official website:

getList(data) {
    return this.http.post(ServicePath.SHOPLIST, data)
}

then introduce service request processing data into the component:

this.service.getList(data).subscribe(res => {
    console.log(res);
})
