我正在尝试读取请求 InputStream 但已到达流的末尾 .
唯一的类（servlet）是：
public class TestServlet extends HttpServlet
{
protected void service(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
{
InputStream clientIn = request.getInputStream();
OutputStream clientOut = response.getOutputStream();
byte[] buffer = new byte[4096];
int n;
try
{
while ((n = clientIn.read(buffer)) != -1) // ---------> Here, n is -1
{
System.out.println(new String(buffer,0,n));
clientOut.write(("Ok = " + n).getBytes());
}
}
catch (Exception e)
{
System.err.println(e);
}
}
}
没有任何其他类（如过滤器，监听器或其他servlet）
并且客户端代码是：
public class Main
{
public static void main(String[] args) throws IOException, InterruptedException
{
String postCommand = "POST / HTTP/1.1\r\n" +
"Host: localhost\r\n" +
"Content-Type: binary/octet-stream\r\n" +
"Connection: keep-alive\r\n\r\n" +
"name1=value1&name2=value2";
Socket socket = new Socket("localhost", 8080);
InputStream serverIn = socket.getInputStream();
OutputStream serverOut = socket.getOutputStream();
serverOut.write(postCommand.getBytes());
int n = 0, count = 1;
byte[] buffer = new byte[4096];
do
{
if (n != 0)
System.out.println(new String(buffer, 0, n));
serverOut.write(("foo " + count).getBytes());
} while ((n = serverIn.read(buffer)) != -1 && count++
先感谢您 . 亲切的问候！

您的客户端没有发送有效的HTTP 1.1 . 没有内容长度标头，因此Servlet无法知道何时停止读取 . 没有实际的流结束，因为HTTP客户端必须保持连接打开才能读取响应 .
使用HttpURLConnection .
