# SpdyStream
A multiplexed stream library using spdy
## Usage
Client example (connecting to mirroring server without auth)
```go
package main
import (
"fmt"
"github.com/moby/spdystream"
"net"
"net/http"
)
func main() {
conn, err := net.Dial("tcp", "localhost:8080")
if err != nil {
panic(err)
}
spdyConn, err := spdystream.NewConnection(conn, false)
if err != nil {
panic(err)
}
go spdyConn.Serve(spdystream.NoOpStreamHandler)
stream, err := spdyConn.CreateStream(http.Header{}, nil, false)
if err != nil {
panic(err)
}
stream.Wait()
fmt.Fprint(stream, "Writing to stream")
buf := make([]byte, 25)
stream.Read(buf)
fmt.Println(string(buf))
stream.Close()
}
```
Server example (mirroring server without auth)
```go
package main
import (
"github.com/moby/spdystream"
"net"
)
func main() {
listener, err := net.Listen("tcp", "localhost:8080")
if err != nil {
panic(err)
}
for {
conn, err := listener.Accept()
if err != nil {
panic(err)
}
spdyConn, err := spdystream.NewConnection(conn, true)
if err != nil {
panic(err)
}
go spdyConn.Serve(spdystream.MirrorStreamHandler)
}
}
