Question

我是Swift Programming和FireBase的新手，我已经实现了聊天应用程序，我只能上传图像和视频，它的工作正常。现在我想上传像Docx，txt，pdf这样的文件，我已经冲了很多，但是我从来没有找到任何解决方案，他们也可以上传文件，任何人都可以建议我的解决方案。

这里有一些上传和下载图片和视频的代码

//Code to send Images and Videos 
       // MARK: - Send media message
    func sendMedia(message : MSMessage, senderRef : FIRDatabaseReference,image : Data?, video : URL? ){
        let image_videos: String?
        if image != nil{
            image_videos = "Send you a Photo"
            let uniqeID : String = "\(NSUUID().uuidString).jpg"

            // save photo in firebase storage
            DBManager.manager.imageStorageRef.child(Constants.USERS_IMAGES_STORAGE)
                .child(message.senderId).child(uniqeID)
                .put(image!, metadata: nil){
                    (metadata : FIRStorageMetadata?, err : Error?) in
                    // problem with upload image
                    if err != nil{ // Error occurred, infrom the user
                        self.delegate?.errorOccurred(description: (err?.localizedDescription)!)
                    }else{// send link to photo in user messages
                        let url = String(describing: metadata!.downloadURL()!)
                        self.sendMessage(message: message, senderRef: senderRef, url : url, fileName : uniqeID)

                    }
            }// dbmanager
        }else{
            let uniqeID : String = NSUUID().uuidString
            image_videos = "Send you a Video"
            // save video in firebase storage
            DBManager.manager.videoStorageRef.child(Constants.USERS_VIDEOS_STORAGE)
                .child(message.senderId).child(uniqeID).putFile(video!, metadata : nil ){

                    }

这是代码

// Get a reference to the storage service using the default Firebase App
let storage = Storage.storage()

// Create a storage reference from our storage service
let storageRef = storage.reference()

// File located on disk
let localFile = URL(string: "path/to/docs/rivers.pdf")!

    // Create a reference to the file you want to upload
    let riversRef = storageRef.child("docs/rivers.pdf")

    // Upload the file to the path "docs/rivers.pdf"
    let uploadTask = riversRef.putFile(from: localFile, metadata: nil) { metadata, error in
      guard let metadata = metadata else {
        // Uh-oh, an error occurred!
        return
      }
      // Metadata contains file metadata such as size, content-type.
      let size = metadata.size
      // You can also access to download URL after upload.
      storageRef.downloadURL { (url, error) in
        guard let downloadURL = url else {
          // Uh-oh, an error occurred!
          return
        }
      }
    }
