如何停止等待最后订阅并显示烤面包机'this.toasterService.pop（'成功'，'电子邮件'，'

现在，在更改changePassword（）之后，accountService.getAll（）会复制，需要在sendEmail（）

之后

this.busy = this.accountService.getAll().subscribe(
  return this.changePassword().add(() => this.sendEmail());
});

 changePassword() {
   return this.accountService.update(this.account).subscribe(
     response => response,
     e        => this.toasterService.pop('error', 'Change Password', e.error.message))
   ;
}

sendEmail() {
    return this.accountService.sendPasswordEmail(this.account).subscribe(
      (response : any) => this.toasterService.pop('success', 'Email', 'Email has been sent, successfully!'),
      (e)              => this.toasterService.pop('error', 'Email', e.error.message))
    ;
  }

Answer 1

尝试以下和check how to handle multiple request here

async getAllAccounts() {
 //this will wait till get all account
 this.busy = await this.accountService.getAll().toPromise();
 //this will complete other operation without wait 
 this.changePAssword();
}

changePassword() {

  return this.accountService.update(this.account).pipe(
        tap(() => add(() => this.sendEmail()))
      ).subscribe(
     response => response,
     e  => this.toasterService.pop('error', 'Change Password', e.error.message));
}

如何随后执行多个.subscribe？
