Question

我正在使用谷歌语音来记录电话并将其发送到谷歌的服务器，以将flac音频文件转换为文本。一切正常在Android 5.0和以前的版本，但从5.02及以上我得到以下错误

private Scanner openHttpsPostConnection(String urlStr, byte[] data) {
    InputStream in = null;
    byte[] mextrad = data;
    int resCode = -1;
    OutputStream out = null;
    // int http_status;
    try {
        URL url = new URL(urlStr);
        URLConnection urlConn = url.openConnection();

        if (!(urlConn instanceof HttpsURLConnection)) {
            throw new IOException("URL is not an Https URL");
        }

        HttpsURLConnection httpConn = (HttpsURLConnection) urlConn;
        httpConn.setAllowUserInteraction(false);
        httpConn.setInstanceFollowRedirects(true);

        httpConn.setRequestMethod("POST");
        //httpConn.setReadTimeout(15*1000);
        httpConn.setDoOutput(true);
        httpConn.setChunkedStreamingMode(0);
        httpConn.setRequestProperty("Content-Type", "audio/x-flac; rate=1600");
                //+ sampleRate);
        httpConn.setRequestProperty("AcceptEncoding", "gzip,deflate,sdch");
        httpConn.connect();

        try {
            // this opens a connection, then sends POST & headers.
            out = httpConn.getOutputStream();
            // Note : if the audio is more than 15 seconds
            // dont write it to UrlConnInputStream all in one block as this
            // sample does.
            // Rather, segment the byteArray and on intermittently, sleeping
            // thread
            // supply bytes to the urlConn Stream at a rate that approaches
            // the bitrate ( =30K per sec. in this instance ).
            Log.d("ParseStarter", "IO beg on data");
            out.write(mextrad); // one big block supplied instantly to the
                                // underlying chunker wont work for duration
                                // > 15 s.
            Log.d("ParseStarter", "IO fin on data");
            // do you need the trailer?
            // NOW you can look at the status.
            resCode = httpConn.getResponseCode();

            Log.d("ParseStarter", "POST OK resp: " +resCode+" "
                    + httpConn.getResponseMessage().getBytes().toString());

            if (resCode / 100 != 2) {
                Log.d("ParseStarter", "POST bad io ");
            }

        } catch (IOException e) {
            Log.d("ParseStarter", "FATAL " + e);

        }

        if (resCode == HttpsURLConnection.HTTP_OK) {
            Log.d("ParseStarter", "OK RESP to POST return scanner ");
            return new Scanner(httpConn.getInputStream());
        }
    } catch (MalformedURLException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
    return null;
}

我正在使用 google speech api v1 。谁能告诉我为什么我会这样做？

这是抛出异常的方法..

OutputStream无法通过它自己在服务器上写入。在获得OutputStream之后，需要创建一个BufferedWriter以在服务器上写入。

.
.
.
try {
// this opens a connection, then sends POST & headers.
out = httpConn.getOutputStream();
// Note : if the audio is more than 15 seconds
// dont write it to UrlConnInputStream all in one block as this
// sample does.
// Rather, segment the byteArray and on intermittently, sleeping
// thread
// supply bytes to the urlConn Stream at a rate that approaches
// the bitrate ( =30K per sec. in this instance ).
BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(out, "UTF-8"));
writer.write(mextrad);
.

编辑：抱歉，我忘记检查您的数据类型了。在这种情况下，你可以尝试改变：

BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(out, "UTF-8"));
writer.write(mextrad);

到

DataOutputStream stream = new DataOutputStream(out);
stream.writeBytes(mextrad);

我之前从未尝试过Android，但我希望它会有所帮助。
