Golang Unmarshal Examples

Example #1

File: appdata.go Project: stoyan/rell

// Unpacks the URL from app_data if possible.
func (h *Handler) ServeHTTP(w http.ResponseWriter, r *http.Request) {
	rawSr := r.FormValue("signed_request")
	if rawSr != "" {
		sr, err := fbsr.Unmarshal([]byte(rawSr), h.Secret, h.MaxAge)
		if err == nil && sr.AppData != "" {
			u, err := Decode(sr.AppData)
			if err == nil {
				r.URL.Path = u.Path
				r.URL.RawQuery = u.RawQuery
				r.Method = "GET"
			}
		}
	}
	h.Handler.ServeHTTP(w, r)
}

Example #2

File: context.go Project: mattwkelly/rell

// Create a context from a HTTP request.

	err := r.ParseMultipartForm(defaultMaxMemory)
	if err != nil {
