Question

我正在尝试将我录制的音频上传到Firebase数据库。录音工作正常，音频也在播放，我只需要上传并下载到其他用户，这样他们就可以收听。该应用程序本身已经发送短信，他们正在工作没有任何问题，用户可以已经在他们之间聊天。

这是我录制的音频（录音会话已经打开）。

@IBAction func sendAudio(_ sender: Any) {
    //Check if there is an active AudioRecorder
    if audioRecorder == nil {
        numberOfRecords += 1
        let filename = getAudioFileURL()

        let settings = [AVFormatIDKey: Int(kAudioFormatMPEG4AAC),
                        AVSampleRateKey: 12000,
                        AVNumberOfChannelsKey: 2,
                        AVEncoderAudioQualityKey: AVAudioQuality.high.rawValue]

        //Start recording
        do {
            audioRecorder = try AVAudioRecorder(url: filename, settings: settings)
            audioRecorder.delegate = self
            audioRecorder.record()

            audioButton.setTitle("Stop", for: .normal)
        } catch {
            alertsAudio(title: "Error", message: "Error!")
        }
    } else {
        //Stop audio recording
        audioRecorder.stop()
        audioRecorder = nil

        UserDefaults.standard.set(numberOfRecords, forKey: "myNumber")
        messageTableView.reloadData()



        audioButton.setTitle("Record", for: .normal)
    }
}

这就是我获取文件URL的方式：

func getDirectory() -> URL {
    let paths = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)
    let documentDirectory = paths[0]
    return documentDirectory
}

func getAudioFileURL() -> URL {
    return getDirectory().appendingPathComponent(".m4a")
}

现在我需要获取此文件网址并将其上传到Firebase，然后在其他用户应用上下载。

我正在使用此方法从firebase中检索文本消息：

func textFieldShouldReturn(_ textField: UITextField) -> Bool {
    textField.resignFirstResponder()
    print("Worked!")
    if messageTextfield.text == "" {
        //o campo de mensagem está em branco
        let alert = UIAlertController(title: "Error!!!!", message: "You can't send a message without text. Please type a message!", preferredStyle: .alert)
        alert.addAction(UIKit.UIAlertAction(title: "Ok", style: .default, handler: nil))
        self.present(alert, animated: true)
        messageTextfield.becomeFirstResponder()
    } else {
        messageTextfield.isEnabled = false
        sendButton.isEnabled = false

        let messagesDB = Database.database().reference().child("Messages")

//            if audioRecorder != nil{
//                message = getDirectory().appendingPathComponent("\(numberOfRecords).m4a")
//            } else {
//                message = messageTextfield.text
//            }

        let messageDict = ["Sender": Auth.auth().currentUser?.email, "MessageBody": messageTextfield.text]

        messagesDB.childByAutoId().setValue(messageDict) {
            (error, reference) in

            if (error) != nil {
                print(error!)
            } else {
                print("Message sent!")

                self.messageTextfield.isEnabled = true
                self.sendButton.isEnabled = true

                self.messageTextfield.text = ""

            }
        }
    }

    return true
}

我解决了这个问题，我的上传方法就像这样：

@IBAction func sendAudio(_ sender: Any) {
    //Check if there is an active AudioRecorder
    if audioRecorder == nil {
        numberOfRecords += 1
        let filename = getAudioFileURL()

        let settings = [AVFormatIDKey: Int(kAudioFormatMPEG4AAC),
                        AVSampleRateKey: 12000,
                        AVNumberOfChannelsKey: 2,
                        AVEncoderAudioQualityKey: AVAudioQuality.high.rawValue]

        //Start recording
        do {
            audioRecorder = try AVAudioRecorder(url: filename, settings: settings)
            audioRecorder.delegate = self
            audioRecorder.record()

            audioButton.setTitle("Stop", for: .normal)
        } catch {
            alertsAudio(title: "Recording error", message: "Error in the audio recording.")
        }
    } else {
        //Stopping the recording
        SVProgressHUD.show()

        audioRecorder.stop()
        audioRecorder = nil

        UserDefaults.standard.set(numberOfRecords, forKey: "myNumber")

        messageTableView.reloadData()
        audioButton.setTitle("Gravar", for: .normal)

        let fileUrl = getAudioFileURL()
        let storage = Storage.storage()
        let metadata = StorageMetadata()


        metadata.contentType = "audio/mp4"
        let refStr = (Auth.auth().currentUser?.email)! + "|" + "\(NSUUID().uuidString)" + "|" + "recording.m4a"
        let pathStr = "Messages/\(NSUUID().uuidString)/\(refStr)"
        let uploadRef = storage.reference().child(pathStr)
        uploadRef.putFile(from: fileUrl, metadata: nil) { metadata,
            error in
            if error == nil {
                print("Successfully Uploaded Audio")
                SVProgressHUD.dismiss()
                let downloadUrl = (metadata?.downloadURL())!
                print("URL: \(downloadUrl)")
                //completion(fileUrl)
                //let messagesDB = Database.database().reference().child("Messages")
                //let key = messagesDB.childByAutoId().key

                var messageInfoArray = refStr.components(separatedBy: "|")
                let messageDict = ["Sender": messageInfoArray[0], "MessageBody": "recording-audioRecorded", "AudioURL": "\(pathStr)", "AudioID": messageInfoArray[1], "IsAudio": "\(NSUUID().uuidString)-True"]

                let childUpdates = ["Mensagens/\(messageInfoArray[1])": messageDict]
                Database.database().reference().updateChildValues(childUpdates)

            }
            else {
                SVProgressHUD.dismiss()
                print("UploadError \(String(describing: error?.localizedDescription))")
                let alert = UIAlertController(title: "Error!!!", message: "The following error ocurred \(String(describing: error?.localizedDescription))", preferredStyle: .alert)
                alert.addAction(UIKit.UIAlertAction(title: "Ok", style: .default, handler: nil))
                self.present(alert, animated: true)
            }
        }

    }
}
