Sam*_*man 8 firebase firebase-security firebase-authentication firebase-storage
我已经在我的应用程序上设置了 Firebase 身份验证和云存储。但是,每当我尝试上传文件时,都会收到一个错误,我找不到任何相关信息。错误是 400: Bad Request 带有以下消息
Listing objects in a bucket is disallowed for rules_version = "1". Please update storage security rules to rules_verison = "2" to use list.
我似乎找不到有关更新安全规则版本的任何信息。请注意,当我查看 firebase 控制台时,实际上上传成功通过,但 HTTP 返回仍然是上述错误。列出对象是什么意思,我该如何更新我的安全规则?
有关更多信息,我的上传代码(在 Kotlin 中)是
fun uploadImage(uri: Uri, path: String): Task<Uri> {
val storageRef = FirebaseStorage.getInstance().reference
val storagePath = storageRef.child(path)
return storagePath.putFile(uri).continueWithTask{ storageRef.downloadUrl }
}

我用
public override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
if (requestCode in 0..2 && resultCode == Activity.RESULT_OK) {
val cropImageUri = CropImage.getActivityResult(data).uri
val systemTime = System.currentTimeMillis()
val path = "$userId/$systemTime"
//IMAGE UPLOAD HERE:
FirebaseImageResource.uploadImage(cropImageUri, path)
.addOnCompleteListener {
if (it.isSuccessful) {
GlideApp.with(this)
.load(cropImageUri)
.into(imageViewForPosition(requestCode)!!)
imageUris[requestCode] = it.result.toString()
}
}
}
}

我的 firebase 规则是默认的:
service firebase.storage {
match /b/{bucket}/o {
match /{allPaths=**} {
allow read, write: if request.auth != null;
}
}
}

我也成功通过 Facebook 登录进行身份验证
override fun onSuccess(loginResult: LoginResult) {
val credential = FacebookAuthProvider.getCredential(loginResult.accessToken.token)
auth.signInWithCredential(credential)
}

(它现在缺少成功侦听器,但我知道它正在工作,因为当我不使用它时,我会收到未经授权的错误,并且文件实际上并未上传)

您需要将其添加到 Firebase 存储规则中:
rules_version = '2';

一个例子是这样的:
rules_version = '2';
service firebase.storage {
match /b/{bucket}/o {
match /{allPaths=**} {
allow read, write: if request.auth != null;
}
}
}

我怀疑这是一个不太有用的错误消息的情况。
只需替换您的上传代码即可
fun uploadImage(uri: Uri, path: String): Task<Uri> {
val storageRef = FirebaseStorage.getInstance().reference
val storagePath = storageRef.child(path)
return storagePath.putFile(uri).continueWithTask{ storageRef.downloadUrl }}

到
fun uploadImage(uri: Uri, path: String): Task<Uri> {
val storageRef = FirebaseStorage.getInstance().reference
val storagePath = storageRef.child(path)
return storagePath.putFile(uri).continueWithTask{ storagePath.downloadUrl }}
