Hi,
I was trying a simple WebSocket test case in development branch.
It doesn't seem working.
Could you please check what's wrong with test case?
// Server:
#include <assert.h>
#include <unistd.h>
#include <string.h>
#include <pthread.h>
#include <stdio.h>
#include <nanomsg/nn.h>
#include <nanomsg/reqrep.h>
int main (const int argc, const char **argv)
{
int sock = nn_socket (AF_SP, NN_REP);
assert (sock >= 0);
assert (nn_bind (sock, "ws://127.0.0.1:80") >= 0);
while (1)
{
char *buf = NULL;
int bytes = nn_recv (sock, &buf, NN_MSG, 0);
assert (bytes >= 0);
printf ("RECEIVED :%s\n", buf);
bytes = nn_send (sock, "Hello", 5, 0);
nn_freemsg (buf);
}
return nn_shutdown (sock, 0);
}
Client:
<!DOCTYPE HTML>
<html>
<head>
<script type="text/javascript">
function WebSocketTest()
{
if ("WebSocket" in window)
{
alert("WebSocket is supported by your Browser!");
// Let us open a web socket
var ws = new WebSocket("ws://127.0.0.1:80", ["rep.sp.nanomsg.org"]);
ws.onopen = function()
{
// Web Socket is connected, send data using send()
alert("Message is sent...");
ws.send("Message");
};
ws.onmessage = function (evt)
{
var received_msg = evt.data;
alert("Message is received...");
};
ws.onclose = function()
{
// websocket is closed.
alert("Connection is closed...");
};
}
else
{
// The browser doesn't support WebSocket
alert("WebSocket NOT supported by your Browser!");
}
}
</script>
</head>
<body>
<div id="sse">
<a href="javascript:WebSocketTest()">Run WebSocket</a>
