URLx

Golang pkg for URL parsing and normalization.

1. Parsing URL (GoDoc)
2. Normalizing URL (GoDoc)
3. Splitting host:port from URL (GoDoc)
4. Resolving IP address from URL (GoDoc)

Parsing URL

The urlx.Parse() is compatible with the same function from net/url pkg, but has slightly different behavior. It enforces default scheme and favors absolute URLs over relative paths.

Difference between urlx and net/url

github.com/goware/urlx	net/url
urlx.Parse("example.com") &url.URL{ Scheme: "http", Host: "example.com", Path: "", }	url.Parse("example.com") &url.URL{ Scheme: "", Host: "", Path: "example.com", }
urlx.Parse("localhost:8080") &url.URL{ Scheme: "http", Host: "localhost:8080", Path: "", Opaque: "", }	url.Parse("localhost:8080") &url.URL{ Scheme: "localhost", Host: "", Path: "", Opaque: "8080", }
urlx.Parse("user.local:8000/path") &url.URL{ Scheme: "http", Host: "user.local:8000", Path: "/path", Opaque: "", }	url.Parse("user.local:8000/path") &url.URL{ Scheme: "user.local", Host: "", Path: "", Opaque: "8000/path", }

Usage

import"github.com/goware/urlx"funcmain() {
url, _:=urlx.Parse("example.com")
// url.Scheme == "http"// url.Host == "example.com"fmt.Print(url)
// Prints http://example.com
}

Normalizing URL

The urlx.Normalize() function normalizes the URL using the predefined subset of Purell flags.

Usage

import"github.com/goware/urlx"funcmain() {
url, _:=urlx.Parse("localhost:80///x///y/z/../././index.html?b=y&a=x#t=20")
normalized, _:=urlx.Normalize(url)
fmt.Print(normalized)
// Prints http://localhost/x/y/index.html?a=x&b=y#t=20
}

Splitting host:port from URL

The urlx.SplitHostPort() is compatible with the same function from net pkg, but has slightly different behavior. It doesn't remove brackets from [IPv6] host.

Usage

import"github.com/goware/urlx"funcmain() {
url, _:=urlx.Parse("localhost:80")
host, port, _:=urlx.SplitHostPort(url)
fmt.Print(host)
// Prints localhostfmt.Print(port)
// Prints 80
}

Resolving IP address from URL

The urlx.Resolve() is compatible with ResolveIPAddr() from net.

Usage

url, _:=urlx.Parse("localhost")
ip, _:=urlx.Resolve(url)
fmt.Print(ip)
// Prints 127.0.0.1
