Constants ¶
const ( // Defaults used by HandleHTTP DefaultRPCPath = "/_goRPC_" DefaultDebugPath = "/debug/rpc" )
Variables ¶
var DefaultServer = NewServer()
DefaultServer is the default instance of *Server.
Functions ¶
func Accept ¶
Accept accepts connections on the listener and serves requests to DefaultServer for each incoming connection. Accept blocks; the caller typically invokes it in a go statement.
func HandleHTTP ¶
func HandleHTTP()
HandleHTTP registers an HTTP handler for RPC messages to DefaultServer on DefaultRPCPath and a debugging handler on DefaultDebugPath. It is still necessary to invoke http.Serve(), typically in a go statement.
func Register ¶
func Register(rcvr interface{}) error
Register publishes the receiver's methods in the DefaultServer.
func RegisterName ¶
RegisterName is like Register but uses the provided name for the type instead of the receiver's concrete type.
func ServeCodec ¶
func ServeCodec(codec ServerCodec)
ServeCodec is like ServeConn but uses the specified codec to decode requests and encode responses.
func ServeConn ¶
func ServeConn(conn io.ReadWriteCloser)
ServeConn runs the DefaultServer on a single connection. ServeConn blocks, serving the connection until the client hangs up. The caller typically invokes ServeConn in a go statement. ServeConn uses the gob wire format (see package gob) on the connection. To use an alternate codec, use ServeCodec. See NewClient's comment for information about concurrent access.
func ServeJSONConn ¶
func ServeJSONConn(conn io.ReadWriteCloser)
ServeConn runs the JSON-RPC server on a single connection. ServeConn blocks, serving the connection until the client hangs up. The caller typically invokes ServeConn in a go statement.
func ServeRequest ¶
func ServeRequest(codec ServerCodec) error
ServeRequest is like ServeCodec but synchronously serves a single request. It does not close the codec upon completion.
Types ¶
type Request ¶
type Request struct { ServiceMethod string // format: "Service.Method" Seq uint64 // sequence number chosen by client // contains filtered or unexported fields }
Request is a header written before every RPC call. It is used internally but documented here as an aid to debugging, such as when analyzing network traffic.
type Response ¶
type Response struct { ServiceMethod string // echoes that of the Request Seq uint64 // echoes that of the request Error string // error, if any. // contains filtered or unexported fields }
Response is a header written before every RPC return. It is used internally but documented here as an aid to debugging, such as when analyzing network traffic.
type Server ¶
type Server struct {
// contains filtered or unexported fields
}
Server represents an RPC Server.
func (*Server) Accept ¶
Accept accepts connections on the listener and serves requests for each incoming connection. Accept blocks until the listener returns a non-nil error. The caller typically invokes Accept in a go statement.
func (*Server) HandleHTTP ¶
HandleHTTP registers an HTTP handler for RPC messages on rpcPath, and a debugging handler on debugPath. It is still necessary to invoke http.Serve(), typically in a go statement.
func (*Server) Register ¶
Register publishes in the server the set of methods of the receiver value that satisfy the following conditions:
- exported method of exported type
- two arguments, both of exported type
- the second argument is a pointer
- one return value, of type error
It returns an error if the receiver is not an exported type or has no suitable methods. It also logs the error using package log. The client accesses each method using a string of the form "Type.Method", where Type is the receiver's concrete type.
func (*Server) RegisterName ¶
RegisterName is like Register but uses the provided name for the type instead of the receiver's concrete type.
func (*Server) ServeCodec ¶
func (server *Server) ServeCodec(codec ServerCodec)
ServeCodec is like ServeConn but uses the specified codec to decode requests and encode responses.
func (*Server) ServeConn ¶
func (server *Server) ServeConn(conn io.ReadWriteCloser)
ServeConn runs the server on a single connection. ServeConn blocks, serving the connection until the client hangs up. The caller typically invokes ServeConn in a go statement. ServeConn uses the gob wire format (see package gob) on the connection. To use an alternate codec, use ServeCodec. See NewClient's comment for information about concurrent access.
func (*Server) ServeHTTP ¶
func (server *Server) ServeHTTP(w http.ResponseWriter, req *http.Request)
ServeHTTP implements an http.Handler that answers RPC requests.
func (*Server) ServeRequest ¶
func (server *Server) ServeRequest(codec ServerCodec) error
ServeRequest is like ServeCodec but synchronously serves a single request. It does not close the codec upon completion.
type ServerCodec ¶
type ServerCodec interface { ReadRequestHeader(*Request) error ReadRequestBody(interface{}) error WriteResponse(*Response, interface{}) error // Close can be called multiple times and must be idempotent. Close() error }
A ServerCodec implements reading of RPC requests and writing of RPC responses for the server side of an RPC session. The server calls ReadRequestHeader and ReadRequestBody in pairs to read requests from the connection, and it calls WriteResponse to write a response back. The server calls Close when finished with the connection. ReadRequestBody may be called with a nil argument to force the body of the request to be read and discarded. See NewClient's comment for information about concurrent access.
func NewServerCodec ¶
func NewServerCodec(conn io.ReadWriteCloser) ServerCodec
NewServerCodec returns a new rpc.ServerCodec using JSON-RPC on conn.
