使用的Angular版本為7.0

引入Router

import { Router } from '@angular/router';

將Router服務(wù)注入

  constructor( private dailyReportDataService: DailyReportDataService, private datePipe: DatePipe, private router: Router  ) { }

調(diào)用方法

        if(datas.resultCode=="FAIL"){
          alert(datas.message);
          this.router.navigateByUrl("/login")
          return;
        }
