【Angular】angular獲取url地址

1、如題，獲取到http://at.worktile.local:18000/flow/rules/5e6c4e6efc77b97260ff6150/overview中的id

    ngOnInit() {
        const ruleDetailRoute = this.activatedRoute.pathFromRoot
            .find(ele => (ele.component as Type<any>).name === 'RuleDetailComponent');

        ruleDetailRoute.params.subscribe((params: Params) => this.ruleId = params.ruleId);
    }
