如何将用户的 Google 帐户照片直接上传到 Firebase 存储？

Question

对于我的 Android 应用程序“本地”，我正在设置 Google 标志。但是，在从他的谷歌帐户中检索用户的个人资料图片并将其上传到 firebase 存储时，我收到了下面显示的错误。

图片上传代码：

  Uri imagePath=Uri.fromFile(newFile(Objects.requireNonNull(account.getPhotoUrl()).toString())); //account holds google signed in user.
  StorageReference storageReference = FirebaseStorage.getInstance().getReference().child("profile_pic").child(firebaseAuth.getUid() + ".jpg"); //The picture is stored in Firebase storage inside profile_pic under the name UID.jpg
  UploadTask uploadTask = storageReference.putFile(imagePath);

错误是：

错误在行：

    UploadTask uploadTask = storageReference.putFile(imagePath);

我只想将他的 google 帐户用户的个人资料图片存储到 profile_pic 文件夹内的 firebase 存储中。

Answer 1

您可以通过 3 种方式使用 Firebase SDK 将文件上传到 Cloud Storage：

1. from data in memory
2. from a stream
3. from a local file

无法从（非本地）网址上传。因此，您首先必须下载文件，然后将其上传到 Cloud Storage。
