android - 上传图像，Firebase 显示 "User does not have permission to access this object"，即使存储设置是公开的

Question

我正在尝试上传图像，然后将所述图像的下载位置存储在 val 中。昨天它工作 100% 完美，没有任何问题。我没有更改任何代码，现在无法上传图像，现在它说

Failed to Upload Image User does not have permission to access this object.

我检查了每个具有相同主题的 stack-overflow/Reddit 帖子，他们都说将我的规则的权限更改为公开。

我的规则设置为公开

service firebase.storage {
  match /b/savephoto-a1cc3.appspot.com/o {
    match /{allPaths=**} {
      allow read, write;
    }
  }
}

这是上传图片的实现。

      val ref = FirebaseStorage.getInstance().getReference("/images/profilePictures/$filename")

        //Stores File
        ref.putFile(selectedPhoto!!)
            .addOnSuccessListener {
                Log.d("main", "Succesfully Uploaded Image ${it.metadata?.path}")

                //Gets Download Link for Image
                ref.downloadUrl.addOnSuccessListener {
                    val downloadImg = it.toString()
                    Log.d("main", "Profile Picture Location $it")
                    //Create User
                    createUser(downloadImg, age, gender, firstName, lastName)
                }
            }
            .addOnFailureListener {
                Log.d("main", "Failed to Upload Image ${it.message}")
            }
    }

仍然不确定为什么我会得到一个

Failed to Upload Image User does not have permission to access this object.

即使规则设置为公开，并且我的代码看起来也完全没问题。 昨天正确上传图像，但现在出现此错误。

对存储桶名称进行硬编码并不是一个好主意。使用变量占位符作为存储桶名称，请参阅 in the documentation .

Storage Security Rules must first specify the service (in our case firebase.storage), and the Cloud Storage bucket (via match /b/{bucket}/o) which rules are evaluated against. The default rules require Firebase Authentication, but here are some examples of other common rules with different access control.

将您的存储规则更改为以下规则以实现您想要的效果。

service firebase.storage {
  match /b/{bucket}/o {
    match /{allPaths=**} {
      allow read, write;
    }
  }
}
