HTTP+SPDY 客户端Java开发包：okhttp

okhttp 是一个 Java 的 HTTP+SPDY 客户端开发包，同时也支持 Android。
kHttp is an HTTP client that’s efficient by default:
- SPDY support allows all requests to the same host to share a socket.
- Connection pooling reduces request latency (if SPDY isn’t available).
- Transparent GZIP shrinks download sizes.
- Response caching avoids the network completely for repeat requests.
示例代码：
OkHttpClient client = new OkHttpClient(); String post(URL url, byte[] body) throws IOException { HttpURLConnection connection = client.open(url); OutputStream out = null; InputStream in = null; try { // Write the request. connection.setRequestMethod("POST"); out = connection.getOutputStream(); out.write(body); out.close(); // Read the response. if (connection.getResponseCode() != HttpURLConnection.HTTP_OK) { throw new IOException("Unexpected HTTP response: " + connection.getResponseCode() + " " + connection.getResponseMessage()); } in = connection.getInputStream(); return readFirstLine(in); } finally { // Clean up. if (out != null) out.close(); if (in != null) in.close(); } }
