Question

我正在尝试与Firebase进行聊天，但出现此错误：类型“ StorageMetadata”的值没有以下代码的成员“ downloadURLs” ：

var fileUrl: String!

func CreateNewRoom(user: User, caption: String, data: NSData) {
    let filePath = "\(user.uid)/\(Int(NSDate.timeIntervalSinceReferenceDate))"
    let metaData = StorageMetadata()
    metaData.contentType = "image/jpg"
    storageRef.child(filePath).putData(data as Data, metadata: metaData) { (metadata, error) in
        if let error = error {
            print("Error uploading: \(error as NSError)")
            return
        }
        self.fileUrl = metadata!.downloadURLs![0].absoluteString
        if let user = Auth.auth().currentUser {
            let idRoom = self.BASE_REF.child("rooms").childByAutoId()
            idRoom.setValue(["caption": caption, "thumbnailUrlFromStorage": self.storageRef.child(metadata!.path!).description, "fileUrl": self.fileUrl])
        }
    }
}

StorageMetadata没有名为downloadURLs的属性，就像您在API documentation中所看到的那样。很久以前就已弃用该功能，并将其从API中删除。您可能正在看一个旧的示例或教程。

如果您需要generate a download URL for a file in Cloud Storage，请使用downloadURL()来获取一个。
