Package gemini implements the Gemini protocol.
|
|
|
|
Get makes a Gemini request:
|
|
|
|
resp, err := gemini.Get("gemini://example.com")
|
|
if err != nil {
|
|
// handle error
|
|
}
|
|
// ...
|
|
|
|
The client must close the response body when finished with it:
|
|
|
|
resp, err := gemini.Get("gemini://example.com")
|
|
if err != nil {
|
|
// handle error
|
|
}
|
|
defer resp.Body.Close()
|
|
body, err := ioutil.ReadAll(resp.Body)
|
|
// ...
|
|
|
|
For control over client behavior, create a Client:
|
|
|
|
var client gemini.Client
|
|
resp, err := client.Get("gemini://example.com")
|
|
if err != nil {
|
|
// handle error
|
|
}
|
|
// ...
|
|
|
|
Clients can load their own list of known hosts:
|
|
|
|
err := client.KnownHosts.Load("path/to/my/known_hosts")
|
|
if err != nil {
|
|
// handle error
|
|
}
|
|
|
|
Clients can control when to trust certificates with TrustCertificate:
|
|
|
|
client.TrustCertificate = func(hostname string, cert *x509.Certificate, knownHosts *gemini.KnownHosts) error {
|
|
return knownHosts.Lookup(hostname, cert)
|
|
}
|
|
|
|
Clients can control what to do when a server requests a certificate:
|
|
|
|
client.GetCertificate = func(hostname string, store *gemini.CertificateStore) *tls.Certificate {
|
|
// If the certificate is in the store, return it
|
|
if cert, err := store.Lookup(hostname); err == nil {
|
|
return &cert
|
|
}
|
|
// Otherwise, generate a certificate
|
|
duration := time.Hour
|
|
cert, err := gemini.NewCertificate(hostname, duration)
|
|
if err != nil {
|
|
return nil
|
|
}
|
|
// Store and return the certificate
|
|
store.Add(hostname, cert)
|
|
return &cert
|
|
}
|
|
|
|
Server is a Gemini server.
|
|
|
|
var server gemini.Server
|
|
|
|
Servers must be configured with certificates:
|
|
|
|
err := server.CertificateStore.Load("/var/lib/gemini/certs")
|
|
if err != nil {
|
|
// handle error
|
|
}
|
|
|
|
Servers can accept requests for multiple hosts and schemes:
|
|
|
|
server.RegisterFunc("example.com", func(w *gemini.ResponseWriter, r *gemini.Request) {
|
|
fmt.Fprint(w, "Welcome to example.com")
|
|
})
|
|
server.RegisterFunc("example.org", func(w *gemini.ResponseWriter, r *gemini.Request) {
|
|
fmt.Fprint(w, "Welcome to example.org")
|
|
})
|
|
server.RegisterFunc("http://example.net", func(w *gemini.ResponseWriter, r *gemini.Request) {
|
|
fmt.Fprint(w, "Proxied content from http://example.net")
|
|
})
|
|
|
|
To start the server, call ListenAndServe:
|
|
|
|
err := server.ListenAndServe()
|
|
if err != nil {
|
|
// handle error
|
|
}
|
|
*/
