BTW because you asked for code, here's how I do requests to my local node for now:

```go
const (
	BasePath = "/ipfs-sync/"
	EndPoint = "http://127.0.0.1:5001"
	API = "/api/v0/"
)

func doRequest(cmd string) (string, error) {
	c := &http.Client{}
	req, err := http.NewRequest("POST", EndPoint+API+cmd, nil)
	if err != nil {
		return "", err
	}
	resp, err := c.Do(req)
	if err != nil {
		return "", err
	}
	defer resp.Body.Close()
	body, err := ioutil.ReadAll(resp.Body)
	if err != nil {
		return "", err
	}
	
	return string(body), nil
}

// use like fmt.Println(doRequest("files/ls"))
```
