传输时出错https://speech.googleapis.com/v1/speech:recognize?key=，myKey&gt；-服务器回答：错误请求[Windows操作系统上的问题]

我正在使用谷歌语音到文本api将音频文件转换为文本。以下是我的代码（Qt）：

   `QString fileName = QDir::currentPath() + "/audio.wav"; //this is my audio file
    QFile audioFile(fileName);
    if(!audioFile.open(QIODevice::ReadOnly | QIODevice::Text)){
        QMessageBox::critical(0,"Error",fileName+" Not found!");
        ui->pushButton_4->setText("Speech to text");
        return;
    }
    int idx = ui->comboBox->currentIndex();
    QString enc;
    if (idx == -1)
        enc = "en-US";
    else
        enc = ui->comboBox->itemData(idx).toString(); //Language selected by user
    QByteArray audioData=audioFile.readAll();
    QUrl url("https://speech.googleapis.com/v1/speech:recognize");
    QUrlQuery query;
    query.addQueryItem("key","myKeyHere...");
    url.setQuery(query);
    QNetworkRequest request(url);
    request.setHeader(QNetworkRequest::ContentTypeHeader,"audio/x-flac");
    QJsonObject json;
    QJsonObject config;
    config["encoding"]="FLAC";
    config["sampleRateHertz"]=44100;
    config["languageCode"]=enc;
    json["config"]=config;
    QJsonObject audio;
    audio["content"]=QString::fromLatin1(audioData.toBase64());
    json["audio"]=audio;
    QByteArray jsonData=QJsonDocument(json).toJson();
    QNetworkAccessManager *manager=new QNetworkAccessManager();
    QNetworkReply *reply=manager->post(request,jsonData);
    QObject::connect(reply,&QNetworkReply::finished,[this,reply](){
        if(reply->error()!=QNetworkReply::NoError){
            QMessageBox::critical(0,"Error Occured",reply->errorString());
            qDebug() << reply->readAll();
            ui->pushButton_4->setText("Speech to text");
            return;
        }
        else if(reply->error()==QNetworkReply::UnknownNetworkError){
            QMessageBox::warning(0,"Network Error","Please check your internet connection and try again!");
            ui->pushButton_4->setText("Speech to text");
        }
        else if(reply->isFinished() && reply->error()==QNetworkReply::NoError){
            QJsonDocument responseJson=QJsonDocument::fromJson(reply->readAll());
            QJsonObject object=responseJson.object();
            QString ResponseText=object["results"].toArray()[0].toObject()
                    ["alternatives"].toArray()[0].toObject()["transcript"].toString();
            QTextCursor cur = curr_browser->textCursor();
            qDebug() << "Response Data :" << ResponseText;
            cur.insertText(ResponseText);
            ui->pushButton_4->setText("Speech to text");
        }
        reply->deleteLater();
    });`

这段代码在Ubuntu上运行得很好，但在windows上却不行。当我在Ubunanuu上运行此程序时，我收到了响应，但在windows上，我收到以下错误：传输错误https://speech.googleapis.com/v1/speech:recognize?key=，myKey>；-服务器答复：请求错误

以下是录制音频文件的代码：

`if (m_audioRecorder->state() == QMediaRecorder::StoppedState) {
      QString fileName = QDir::currentPath() + "/audio.wav";
      m_audioRecorder->setOutputLocation(QUrl::fromLocalFile(fileName));
      qDebug()<<"Recording your audio!!";
      ui->pushButton_4->setText("Stop ?");
      QAudioEncoderSettings settings;
      settings.setCodec("audio/x-flac");
      settings.setSampleRate(0);
      settings.setBitRate(0);
      settings.setChannelCount(1);
      settings.setQuality(QMultimedia::EncodingQuality(2));
      settings.setEncodingMode(QMultimedia::ConstantQualityEncoding);

      m_audioRecorder->setEncodingSettings(settings, QVideoEncoderSettings(), "");
      m_audioRecorder->record();
  }
  else {
      qDebug()<<"stopped your recording!";
      ui->pushButton_4->setText("Processing ...");
      m_audioRecorder->stop();
      speechToTextCall(); //calling the code to send request to google api
  }`

有人能帮忙吗？

我尝试更改编码和容器类型，但在Windows上没有任何效果。
