Question

所以我有这个小代码片段负责将图片上传到firebase存储。由于某些奇怪的原因，我的访问权限一直被拒绝。 storageRef似乎存在问题，因为它会进入if语句，打印出错误。

  // will handle the  sign up of a user
    @objc func handleSignUp(){
        // first we cant to take sure that all of the fields are filled
        var profilePic: String = ""

        // will take the user selected image and load it to firebase
        let imageName = NSUUID().uuidString
 let storageRef = Storage.storage().reference().child("profile_images").child("\(imageName).PNG")
        if let userImage = selectedImageFromPicker,let uploadData = UIImageJPEGRepresentation(userImage, 0.1){

            storageRef.putData(uploadData, metadata: nil, completion: { (metadata, error) in
                if error != nil{
                    print(error ?? "")
                    return
                }
                 profilePic = (metadata?.downloadURL()!.absoluteString)!
                guard let username = self.nameTextField.text,
                    let confirmPassword = self.confirmPasswordTextField.text,
                    let email = self.emailTextField.text,
                    let password = self.passwordTextField.text,
                    !username.isEmpty,
                    !email.isEmpty,
                    !password.isEmpty,
                    !confirmPassword.isEmpty
                    else {

                        print("Required fields are not all filled!")
                        return
                }
                if self.validateEmail(enteredEmail:email) != true{
                    let alertController = UIAlertController(title: "Error", message: "Please Enter A Valid Email", preferredStyle: .alert)
                    let defaultAction = UIAlertAction(title: "Ok", style: .cancel, handler: nil)
                    alertController.addAction(defaultAction)
                    self.present(alertController, animated: true, completion: nil)
                }

                // will make sure user is validated before it even tries to create user

                // will make sure the password and confirm password textfields have the same value if so it will print an error
                if self.passwordTextField.text != self.confirmPasswordTextField.text {
                    let alertController = UIAlertController(title: "Error", message: "Passwords Don't Match", preferredStyle: .alert)
                    let defaultAction = UIAlertAction(title: "Ok", style: .cancel, handler: nil)
                    alertController.addAction(defaultAction)
                    self.present(alertController, animated: true, completion: nil)
                }

                // will authenticate a user into the authentication services with an email and passowrd
                AuthService.createUser(controller: self, email: email, password: password) { (authUser) in
                    guard let firUser = authUser else {
                        return
                    }
                    //will add user to the database
                    print(profilePic)
                    print(username)
                    UserService.create(firUser, username: username , profilePic: profilePic,location: self.userLocation!) { (user) in
                        guard let user = user else {
                            print("User successfully loaded into firebase db")
                            return
                        }
                        // will set the current user for userdefaults to work
                        print(user.profilePic)
                        print(user.username)

                        User.setCurrent(user, writeToUserDefaults: true)
                        // self.delegate?.finishSigningUp()

                        self.finishSigningUp()


                    }
                }

        })
        }
    }

错误是

Error Domain=FIRStorageErrorDomain Code=-13021 "User does not have permission to access gs://eventful-3d558.appspot.com/profile_images/C0BC898A-6A6F-490F-954B-51D705CD2B23.PNG."

  "error": {
    "code": 403,
    "message": "Permission denied. Could not perform this operation"
  }

如果有人知道它是什么我会很感激你的帮助。它阻止我注册用户。

Answer 1

您必须将数据库规则设置为接受所有读取和写入数据库 - ＆gt;规则

{
  "rules": {
  ".read": true,
  ".write": true
  }
}

通过将数据库读写规则设置为true，可以设置允许的所有读写请求。

如果您在Firebase存储中发现了一些权限错误，请更改Firebase存储 - >规则

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

Answer 2

请务必检查Firebase身份验证。

Firebase存储分区需要Firebase身份验证才能上传文件。
