)
func main() {
// Open File
f, err := os.Open("/usr/local/Cellar/graphviz/10.0.1/share/doc/graphviz/libguide.pdf")
if err != nil {
panic(err)
}
defer f.Close()
buffer := make([]byte, 512)
if _, err := f.Read(buffer); err != nil {
panic(err)
}
contentType := http.DetectContentType(buffer)
fmt.Println("Content Type: " + contentType)
