用HttpURLConnection发送二进制数据 [英] Sending binary data with HttpURLConnection

问题描述

我想使用谷歌语音API，我发现这个 https：// github。 com / gillesdemey / google-speech-v2 / ，其中一切都很好解释，但是我试图把它改写成java。

i want to use google speech api, i've found this https://github.com/gillesdemey/google-speech-v2/ where everything is explained well, but and im trying to rewrite it into java.

File filetosend = new File(path);
byte[] bytearray = Files.readAllBytes(filetosend);
URL url = new URL("https://www.google.com/speech-api/v2/recognize?output="+outputtype+"&lang="+lang+"&key="+key);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
//method
conn.setRequestMethod("POST");
//header
conn.setRequestProperty("Content-Type", "audio/x-flac; rate=44100");

现在我失去了......我想我需要将bytearray添加到请求中。在示例中它的行

now im lost... i guess i need to add the bytearray into the request. in the example its line

--data-binary @audio/good-morning-google.flac \

但是httpurlconnection类没有附加二进制数据的方法。

but httpurlconnection class has no method for attaching binary data.

推荐答案

但它有 getOutputStream（），您可以在其中编写数据。您可能还想调用 setDoOutput（true）。

But it has getOutputStream() to which you can write your data. You may also want to call setDoOutput(true).
