Question

有没有办法让URL请求链接特定于用户？我正在尝试与用户特定的Firebase存储文件建立某些链接。我是否必须更改xcode或Firebase存储规则中的代码？

func yhandleDownload() {
    print(123)
    let webView = UIWebView (frame: view.frame)
    webView.backgroundColor = UIColor.black
    view.addSubview(webView)
    webView.loadRequest(URLRequest(url: URL(string: "https://firebasestorage.googleapis.com")!))

    webView.scalesPageToFit = true

这就是我现在设置代码的方式，它允许登录到应用程序的所有用户打开链接。

您应该使用内置的下载方法（例如，我们将使用FirebaseUI直接将图像下载到UIImageView）：

// Get the current user's UID
let currentUser = FIRAuth.auth().currentUser?.uid

// Reference to a user's image file in Firebase Storage
let reference = storageRef.child("users/\(currentUser)/image.png")

// UIImageView in your ViewController
let imageView: UIImageView = self.imageView

// Placeholder image
let placeholderImage = UIImage(named: "placeholder.jpg")

// Load the image using SDWebImage
imageView.sd_setImage(with: reference, placeholderImage: placeholderImage)

除了适当设置安全规则外：

service firebase.storage {
  match /b/{bucket}/o {
    match /users/{userId}/{allUserFiles=**} {
      allow read, write: if request.auth.uid == userId;
    }
  }
}
