epp-lib is a library implementing an EPP server and some nice to haves around EPP.
A working EPP server with configurable variables like timeouts and max message size allowed.
Example server initialization:
commandMux := &CommandMux{}
server := &Server{
HandleCommand: commandMux.Handle,
Greeting: commandMux.GetGreeting,
TLSConfig: tls.Config{
Certificates: []tls.Certificate{tlsCert},
ClientAuth: tls.RequireAnyClientCert,
MinVersion: tls.VersionTLS12,
},
Timeout: time.Hour,
IdleTimeout: 350 * time.Second,
WriteTimeout: 2 * time.Minute,
ReadTimeout: 10 * time.Second,
ErrorLog: log, // whichever log you prefer that fit the interface
MaxMessageSize: 1000,
}
listener, err := net.ListenTCP("tcp", tcpAddr)
if err != nil {
panic(err)
}
if err := server.Serve(listener); err != nil {
panic(err)
}The server ConnContext can be used to set custom data on the context.
For example if you want to create a session ID for the connection or something.
The server CloseConnHook if set is called when a connection is closed.
It can be used to for example tear down any data for the connection.
The CommandMux.Handle function parse the incoming commands
and calls the correct CommandFunc if one has been
configured for the specific command.
Example bind of commands:
commandMux := &CommandMux{}
commandMux.BindGreeting(funcThatHandlesGreetingCommand)
commandMux.Bind(
xml.NewXMLPathBuilder().
AddOrphan("//hello", NamespaceIETFEPP10.String()).String(),
funcThatHandlesHelloCommand,
)
commandMux.BindCommand("info", NamespaceIETFContact10.String(),
funcTharHandlesContactInfoCommand,
)
server.HandleCommand = commandMux.Handle
server.Greeting = commandMux.GetGreetingSome nice to have convenience methods for xml. XMLString that automatically xml escape
the given string when the Stringer interface is used. ParseXMLBool function that handle 0, 1,
true and false and converts to go bool. XMLPathBuilder makes it easier to build xml paths.
Example:
// equals "name[namespace-uri()='urn:ietf:params:xml:ns:contact-1.0']"
NewXMLPathBuilder().AddOrphan("name", "urn:ietf:params:xml:ns:contact-1.0").String()
// equals "//command[namespace-uri()='random:namespace']/check[namespace-uri()='urn:ietf:params:xml:ns:contact-1.0']"
NewXMLPathBuilder().
Add("//command", "random:namespace").
Add("check", "urn:ietf:params:xml:ns:contact-1.0").String()The Swedish Internet Foundation is an independent, private foundation that works for the positive development of the internet.
