Options

Option	Type	Default
method=	string	GET
data=	io.Reader	nil
dialtimeout=	time.Duration	0
readtimeout=	time.Duration	0
timeout=	time.Duration	0
cbinterval=	time.Duration	time.Second
followredirects=	bool	true
deadline=	time.Time or time.Duration	0
maxspeed=	int64	0
header=	http.Header	nil
disablecompression=	bool	false

Advanced Usage

Set monitor callback interval

curl.File("xxxx", "xxx", cb, "cbinterval=", 0.5) // 0.5 second

Curl in goroutine

con := &curl.Control{}
go curl.File("xxx", "xxx", con)
// and then get stat
st := con.Stat()
// or stop
con.Stop()
// set max speed
con.MaxSpeed(1024*10)
// cancel max speed
con.MaxSpeed(0)

Just dial

err, resp := curl.Dial("http://de.edis.at/10MB.test", "timeout=11")
fmt.Println("contentLength=", resp.ContentLength)

Useful Functions

Functions format size, speed pretty

curl.PrettySize(100000000)) // 95.4MB
curl.PrettyPer(0.345) // 34.5%
curl.PrettySpeed(1200) // 1.2KB/s
curl.PrettyDur(time.Second*66) // 1:06

Progressed io.Copy

r, _ := os.Open("infile")
w, _ := os.Create("outfile")
length := 1024*888
cb := func (st curl.IoCopyStat) error {
  fmt.Println(st.Perstr, st.Sizestr, st.Lengthstr, st.Speedstr, st.Durstr)
  return nil
}
curl.IoCopy(r, length, w, "readtimeout=12", cb)
