golang 1.5 坑一枚

golang 1.5 在常用的net/http包里新增了Request.Cancel, 导致原来可以直接把request给json化的方式出现了json: unsupported type: <-chan struct {}. 在debug的时候看不到请求了. 解决方式也十分坑…

type Req struct {
	Method           string
	URL              *url.URL
	Proto            string
	ProtoMajor       int
	ProtoMinor       int
	Header           http.Header
	ContentLength    int64
	TransferEncoding []string
	Close            bool
	Host             string
	Form             url.Values
	PostForm         url.Values
	MultipartForm    *multipart.Form
	Trailer          http.Header
	RemoteAddr       string
	RequestURI       string
	TLS              *tls.ConnectionState
}
func CopyReq(req *http.Request) *Req {
	return &Req{
		Method:           req.Method,
		URL:              req.URL,
		Proto:            req.Proto,
		ProtoMajor:       req.ProtoMajor,
		ProtoMinor:       req.ProtoMinor,
		Header:           req.Header,
		ContentLength:    req.ContentLength,
		TransferEncoding: req.TransferEncoding,
		Close:            req.Close,
		Host:             req.Host,
		Form:             req.Form,
		PostForm:         req.PostForm,
		MultipartForm:    req.MultipartForm,
		Trailer:          req.Trailer,
		RemoteAddr:       req.RemoteAddr,
		RequestURI:       req.RequestURI,
		TLS:              req.TLS,
	}
}
