I am starting to play with Rust, but I got stuck early on with a trivial
TCP client example. (There's a few server examples out there, but I
couldn't find a single working client anywhere. I tried the archives,
the tests, etc.)
My naive approach sends some data to the server and then attempts to
read, but socket.read() always times out. I have verified that the
server is receiving the request and responding to it.
I came across a couple of tickets that suggest that I might be handling
the event loop incorrectly, but I don't know enough to fix the code.
Your help is appreciated. Thanks.
extern mod extra;
use extra::net::{ip, tcp};
use extra::uv;
use std::str;
fn main() {
let ip_addr = ip::v4::parse_addr("204.232.212.130");
let iotask = &uv::global_loop::get();
let r = tcp::connect(ip_addr, 80, iotask);
match(r) {
Err(err) => {
println(fmt!("Connection failed: %?", err))
}
Ok(socket) => {
let r = socket.write(bytes!("GET /
HTTP/1.0\r\n\r\n").to_owned());
if (r.is_err()) {
println(fmt!("Write error: %?", r.get_err()))
} else {
let r = socket.read(2000);
if (r.is_err()) {
println(fmt!("Read error: %?", r.get_err()))
} else {
let bytes = r.get();
println(str::from_bytes(bytes));
}
}
}
}
}
