go-saml 介绍
go-saml 是 Go 语言的 SAML 开发包。
示例代码：
package main
import (
"crypto/rsa"
"crypto/tls"
"crypto/x509"
"fmt"
"net/http"
"net/url"
"github.com/crewjam/saml/samlsp"
)
func hello(w http.ResponseWriter, r *http.Request) {
fmt.Fprintf(w, "Hello, %s!", samlsp.Token(r.Context()).Attributes.Get("cn"))
}
func main() {
keyPair, err := tls.LoadX509KeyPair("myservice.cert", "myservice.key")
if err != nil {
panic(err) // TODO handle error
}
keyPair.Leaf, err = x509.ParseCertificate(keyPair.Certificate[0])
if err != nil {
panic(err) // TODO handle error
}
idpMetadataURL, err := url.Parse("https://www.testshib.org/metadata/testshib-providers.xml")
if err != nil {
panic(err) // TODO handle error
}
rootURL, err := url.Parse("http://localhost:8000")
if err != nil {
panic(err) // TODO handle error
}
samlSP, _ := samlsp.New(samlsp.Options{
URL: *rootURL,
Key: keyPair.PrivateKey.(*rsa.PrivateKey),
Certificate: keyPair.Leaf,
IDPMetadataURL: idpMetadataURL,
})
app := http.HandlerFunc(hello)
http.Handle("/hello", samlSP.RequireAccount(app))
http.Handle("/saml/", samlSP)
http.ListenAndServe(":8000", nil)
}
