Firebase 存储异常：用户无权访问此对象

Question

将图片上传到 firebase 存储时出现以下错误。

插件版本：

image_picker: ^0.6.7+3
firebase_storage: ^3.1.6
permission_handler: ^5.0.1+1

Firebase 存储规则：

rules_version = '2';
service firebase.storage {
  match /b/{bucket}/o {
    match /{allPaths=**} {
      allow read, write: if false;
    }
  }
}

以及我在调试控制台中得到的完整错误：

和一段代码

PickedFile image;
await Permission.photos.request();
var permissionStatus = await Permission.photos.status;
if (permissionStatus.isGranted) {

    image = await _picker.getImage(source: ImageSource.gallery);
    if (image != null) {
       var imageUrl = await storageService.uploadProductImage(
       File(image.path), uuid.v4());
       changeImageUrl(imageUrl)
    } else {
       print('No Path Received');
    }
} else {
    print('Grant Permissions and try again');
}

之前我已经成功认证了firebase服务。我使用 Android 和模拟器来制作它。我错过了什么？

Answer 1

在您的 Firebase 规则中，

allow read, write: if false;

表示无法在您的数据库上读取或写入。您可以将其更改为 if true 以测试这是否是您问题的原因，然后使用更准确的规则。
