如何在不使用异步等待的情况下以角度获取订阅内的价值

Question

How do you extract the value inside the subscribe on angular.

I have this code:

 async trackingInfo(trackingNumber) {
    const foo = await this.userService
      .trackOrderStatus(trackingNumber)
      .subscribe((status) => {
        console.log(status, 'stat');
        return status;
      });
    console.log(foo, 'grrr');
  }

foo returns the subscription not the status I know theres away not to use async await but i totally forgot. much appreciate the help. thanks

Assign it to something in the subscribe block:

status: any;

trackingInfo(trackingNumber) {
    const foo = this.userService
      .trackOrderStatus(trackingNumber)
      .subscribe((status) => {
        console.log(status, 'stat');
        this.status = status;
      });
    console.log(foo, 'grrr');
  }
