示例1: file

{
if(! launch_server)
{
return;
}
// read png data into a string.
// in the real example, we should have the png in memory
std::string wsock_path = utils::join_file_path(CONDUIT_WEB_CLIENT_ROOT,
"wsock_test");
std::string example_png_path = utils::join_file_path(wsock_path,
"example.png");
CONDUIT_INFO("png path:" << example_png_path);
std::ifstream file(example_png_path.c_str(),

// find out how big the png file is
file.seekg(0, std::ios::end);
std::streamsize png_raw_bytes = file.tellg();
file.seekg(0, std::ios::beg);
// use a node to hold the buffers for raw and base64 encoded png data
Node png_data;
png_data["raw"].set(DataType::c_char(png_raw_bytes));
char *png_raw_ptr = png_data["raw"].value();
// read in the raw png data

// create the message we want to send.
Node msg;
msg["type"] = "image";
// the goal is to drop this directly into a <img> element in our web client

// we will update the count with every send
msg["count"] = 0;

// this loop won't be necessary in the strawman lib.
while(svr.is_running())

// websocket() returns the first active websocket
svr.websocket()->send(msg);
// or with a very short timeout
//svr.websocket(10,100)->send(msg);
