Go HTTP包源码阅读 持续更新 0.0

首先定义了几种错误
ErrBodyNotAllowed = errors.New(“http: request method or response status code does not allow body”)
ErrHijacked = errors.New(“http: connection has been hijacked”)
ErrContentLength = errors.New(“http: wrote more than the declared Content-Length”)
ErrWriteAfterFlush = errors.New(“unused”)

然后是我们常见常用的 Handler接口
type Handler interface {
ServeHTTP(ResponseWriter, *Request)
}

这个是一个不推荐使用的接口，是用来断开链接的 因为现在有了Context包，
type CloseNotifier interface{
CloseNotify() <-chan bool
}

type conn struct {
server *Server
cancelCtx context.CancelFunc
rwc net.Conn
remoteAddr string
tlsState *tls.ConnectionState
werr error
r *connReader
bufr *bufio.Reader
bufw *bufio.Writer
lastMethod string
curReq atomic.Value // of *response (which has a Request in it)
curState struct{ atomic uint64 } // packed (unixtime<<8|uint8(ConnState))
mu sync.Mutex
hijackedv bool
}
