你可以打电话 console.log 在“success”回调中:

this.dataService.getData().subscribe(data => {
  this.localData = data; 
  console.log(this.localData);
});

this.dataService.getData().subscribe(
  data => { this.localData = data; },
  error => {},
  () => { console.log(this.localData); });

    this.dataService.getData().subscribe(

       this.localData = data, 
       console.log(this.localData)
