我正在尝试使用以下代码获取受密码保护的pfx文件的指纹:

function Get-CertificateThumbprint {
    # 
    # This will return a certificate thumbprint, null if the file isn't found or throw an exception.
    #

    param (
        [parameter(Mandatory = $true)][string] $CertificatePath,
        [parameter(Mandatory = $false)][string] $CertificatePassword
    )

    try {
        if (!(Test-Path $CertificatePath)) {
            return $null;
        }

        if ($CertificatePassword) {
            $sSecStrPassword = ConvertTo-SecureString -String $CertificatePassword -Force –AsPlainText
        }

        $certificateObject = New-Object System.Security.Cryptography.X509Certificates.X509Certificate2
        $certificateObject.Import($CertificatePath, $sSecStrPassword);

        return $certificateObject.Thumbprint
    } catch [Exception] {
        # 
        # Catch accounts already added.
        throw $_;
    }
}

当我运行它时,我收到此错误:

我正在尝试找出如何在 TypeScipt 中获取 Firebase Authenticated 用户的 uid：

<div> {{ (user | async)?.uid }} </div>

我有以下 TS 代码：

import { AngularFireAuth } from 'angularfire2/auth';
import * as firebase from 'firebase/app'

@Component({
  selector: 'app-user-portal',
  templateUrl: './user-portal.component.html',
  styleUrls: ['./user-portal.component.css']
})
export class UserPortalComponent implements OnInit {
  user: Observable<firebase.User>;

  constructor(
              public afAuth: AngularFireAuth
  ) {
    this.user = afAuth.authState;
  }

  ngOnInit() {

  }
}

我读过的所有内容都表明我需要访问...的 id 属性

this.afAuth.auth.currentUser.uid

......但这似乎没有暴露。如果我把它改成...

this.afAuth.auth.currentUser.toJSON()

...并将其发送到控制台，然后我确实看到了一个 uid 属性。我怎样才能得到那个财产？

这甚至是为用户获取 uid 的正确方法吗？将...

this.afAuth.auth.currentUser.getIdToken()

... 会更好？如果这样更好，我也看不出如何从中获取 uid。建议？

我有以下代码：

this.afDb.list('/demo').push({a: 'b'})
    .then(_ => console.log('works'))
    .catch(err => console.log('err: ', err));

我在“捕获”上收到以下错误：

[ts] Property 'catch' does not exist on type 'PromiseLike<any>'.

看起来像一个 AngularFire2 错误？
