Question

我正在研究一个简单的应用程序＆＃34;语音文字＆＃34;通过Google Speech API v2。我创建了一个Java项目并下载了一个flac文件（good-morning-google.flac）来测试它。

当我将flac文件发送到谷歌服务器时，我收到以下错误：

java.io.IOException：写入服务器时出错。完成时间 sun.net.www.protocol.http.HttpURLConnection.writeRequests（未知来源）at sun.net.www.protocol.http.HttpURLConnection.writeRequests（未知来源）at sun.net.www.protocol.http.HttpURLConnection.getInputStream（未知来自java.net.HttpURLConnection.getResponseCode（未知来源）在java.net.HttpURLConnection.getResponseMessage（未知来源）at sun.net.www.protocol.https.HttpsURLConnectionImpl.getResponseMessage（未知来自）speech.JavaSoundRecorder.main（JavaSoundRecorder.java:140）

我认为问题在于网址的定义，但我不确定。有人可以帮我解决吗？

这是我连接谷歌服务器的代码：

    String urlString = "https://www.google.com/speech-api/v2/recognize?output=json&lang=en-US&" + key;
    try {
    url = new URL(urlString);
    HttpURLConnection connection = (HttpURLConnection) url.openConnection();
    StringBuilder stringBuilder;

    connection.setDefaultUseCaches(true);
    connection.setConnectTimeout(20000);
    connection.setReadTimeout(60000);
    connection.setDoInput(true);
    connection.setDoOutput(true);
    connection.setInstanceFollowRedirects(true);
    connection.setRequestMethod("POST");
    connection.setRequestProperty("Content-Type", "audio/x-flac;rate=44100");

    /*Write the audio on bufferI/O*/
    File file = new File("C:/Travail/audio/good-morning-google.flac");
    byte[] buffer = new byte[(int) file.length()];
    FileInputStream fis = new FileInputStream(file);
    fis.read(buffer);
    fis.close();
    OutputStream os = connection.getOutputStream();
    os.write(buffer);
    os.close();

    connection.connect();
    System.out.println("connect to google server!");
    connection.getResponseMessage();
    System.out.println("receive the reponse!");
    InputStreamReader inputStreamReader = new InputStreamReader(
            connection.getInputStream(), "UTF-8");
    BufferedReader br = new BufferedReader(inputStreamReader);

    stringBuilder = new StringBuilder();
    String line = null;
      while ((line = br.readLine()) != null)
      {
        stringBuilder.append(line + "\n");
      }
      System.out.println(stringBuilder);
     // JSONObject jsonResponse = new JSONObject(stringBuilder.toString());
} catch (MalformedURLException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
} catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

Answer 1

首先使用CURL发布flac文件。

然后，检查来自＆＃34;连接＆＃34;的http标头。在java中看到它们与curl相匹配......

如果它们非常接近，那么java帖子也应该有效。

您在网址定义中的“+ key”之前错过了&key=
