MiniHttpServer.java - an HTTP Server in 168 lines
For part of an project which I'll be announcing shortly, I needed an extremely lightweight HTTP server. Fortunately, HTTP is quite easy-to-implement. Tonight I hacked together MiniHttpServer.java, a simple server with zero third-party dependencies.I was able to support the core of HTTP in with just 168 lines by doing only the bare-minimum. Here's the server's core:
nextLine();
readUntil("GET\\s+");
String url = readUntil("\\s+HTTP/1.1");
do {
nextLine();
} while (readUntil("$").length() > 0);
InputStream responseData = handler.getResponse(url);
if (responseData != null) {
write("HTTP/1.1 200 OK\r\n\r\n");
int b;
while ((b = responseData.read()) != -1) {
connection.getOutputStream().write(b);
}
} else {
write("HTTP/1.1 404 Not Found\r\n\r\n");
write("404 Not Found: " + url);
}
connection.close();If you need an embedded HTTP server, please help yourself to this code. It's fully open source, and available under your choice of Mozilla 1.1 or LGPL license.
