等待模态响应时刷新代码块

Question

这个想法是当用户处理某些东西并尝试运行一些敏感组件时，他需要确认密码。这样，我们可以验证用户身份。 确认密码对话框如下所示：

appGlobal.service.ts中的方法

  OpenACLModal() {
    this.aclModal.open(AccessControlListComponent, { width: '450px' });
  }

这是access-control-list.service.ts中的Open方法

  //Open a new dialog window with the specified configuration.
  open(content: any, config: MatDialogConfig = {}): MatDialogRef<any> {
    const dialog = this.dialog.open(content, config);

    this.stack.push(dialog);

    return dialog;
  }

因此，现在我可以只用appGlobal.service.ts

中引用的一行代码触发模态

 let modal = this.appGlobal.OpenACLModal();

当我在模式上单击“确定”时，将执行以下操作：

AuthUser() {
    let auth = new Authorize();
    auth.Credentials.CredentialsData1 = this.email;
    auth.Credentials.CredentialsData2 = this.password;

    this.http.post(this.appGlobal.BASE_SERVER_ADDRESS + 'api/AppServer/Authorize', auth).subscribe((res) => {
      if (res['IsAuthorized'] == true) {
        // do something
      }
      else // do something
    });
  }

问：我想做类似的事情：

let modal = this.appGlobal.OpenACLModal();
    if (modal==true)
    {
        // I want to freeze code here and wait for the response of modal 
        // Check response if true
        // do something
    }
    else alert("You don't have permission to perform this kind of action");

该怎么做？谢谢任何人。
