# go-http-ntlm
go-http-ntlm is a Go package that contains NTLM transport (`http.RoundTripper` implementation) for `http.Client` to make NTLM auth protected http requests.
It is based on [https://github.com/ThomsonReutersEikon/go-ntlm](https://github.com/ThomsonReutersEikon/go-ntlm) library.
## Usage example
```go
package main
import (
"io/ioutil"
"log"
"net/http"
"strings"
"github.com/vadimi/go-http-ntlm"
)
func main() {
// configure http client
client := http.Client{
Transport: &httpntlm.NtlmTransport{
Domain: "mydomain",
User: "testuser",
Password: "fish",
},
}
req, err := http.NewRequest("GET", "http://server/ntlm-auth-resource", strings.NewReader(""))
resp, err := client.Do(req)
if err != nil {
log.Fatal(err)
}
defer func() {
err := resp.Body.Close()
if err != nil {
log.Fatal(err)
}
}()
body, err := ioutil.ReadAll(resp.Body)
if err != nil {
log.Fatal(err)
}
log.Println(body)
}
```
