rawhttp

rawhttp is a Go package for making HTTP requests. It intends to fill a niche that https://golang.org/pkg/net/http/ does not cover: having complete control over the requests being sent to the server.

rawhttp purposefully does as little validation as possible, and you can override just about anything about the request; even the line endings.

Warning: This is a work in progress. The API isn't fixed yet.

Full documentation can be found on GoDoc.

Example

req, err := rawhttp.FromURL("POST", "https://httpbin.org")
if err != nil {
	log.Fatal(err)
}

// automatically set the host header
req.AutoSetHost()

req.Method = "PUT"
req.Hostname = "httpbin.org"
req.Port = "443"
req.Path = "/anything"
req.Query = "one=1&two=2"
req.Fragment = "anchor"
req.Proto = "HTTP/1.1"
req.EOL = "\r\n"

req.AddHeader("Content-Type: application/x-www-form-urlencoded")

req.Body = "username=AzureDiamond&password=hunter2"

// automatically set the Content-Length header
req.AutoSetContentLength()

fmt.Printf("%s\n\n", req.String())

resp, err := rawhttp.Do(req)
if err != nil {
	log.Fatal(err)
}

fmt.Printf("< %s\n", resp.StatusLine())
for _, h := range resp.Headers() {
	fmt.Printf("< %s\n", h)
}

fmt.Printf("\n%s\n", resp.Body())
