写贴代码吧：
Socket socket = new Socket();
InetSocketAddress inetSocketAddress = new InetSocketAddress("music.163.com", 80);
socket.connect(inetSocketAddress);
OutputStream outputStream = socket.getOutputStream();
BufferedWriter bufferedWriter = new BufferedWriter(new OutputStreamWriter(outputStream));
bufferedWriter.write("GET /artist?id=10000 HTTP/1.1\r\n");
bufferedWriter.write("Host: music.163.com\r\n");
bufferedWriter.write("User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36\r\n");
bufferedWriter.write("Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8\r\n");
bufferedWriter.write("Accept-Language: zh-CN,zh;q=0.9,en;q=0.8,fr;q=0.7\r\n");
bufferedWriter.write("\r\n");
bufferedWriter.flush();
InputStream inputStream = socket.getInputStream();
byte[] bytes = new byte[1024];
ByteArrayOutputStream baos = new ByteArrayOutputStream(1024 * 1024 * 4);
int len;
while ((len = inputStream.read(bytes, 0, bytes.length)) > 0) {
baos.write(bytes, 0, len);
}
System.out.println(baos.toString(StandardCharsets.UTF_8.name()));
输出如下：

响应里面，响应头和响应体之间的 'a3e\n' 是什么鬼？是因为网易的服务器没严格按照 http 协议来吗？还是说有啥特殊含义呢?
