示例1: DeleteHandler

func (vs *VolumeServer) DeleteHandler(w http.ResponseWriter, r *http.Request) {
	n := new(storage.Needle)
	vid, nid, _, _, _ := parseURLPath(r.URL.Path)
	volumeId, _ := storage.NewVolumeId(vid)
	n.ParseNid(nid)

	glog.V(2).Infoln("deleting", n)

	cookie := n.Cookie

	if _, ok := vs.store.ReadVolumeNeedleNoCache(volumeId, n); ok != nil {
		m := make(map[string]uint32)
		m["size"] = 0
		writeJsonQuiet(w, r, http.StatusNotFound, m)
		return
	}

	if n.Cookie != cookie {
		glog.V(0).Infoln("delete", r.URL.Path, "with unmaching cookie from ", r.RemoteAddr, "agent", r.UserAgent())
		writeJsonError(w, r, http.StatusBadRequest, errors.New("File Random Cookie does not match."))
		return
	}

	count := int64(n.Size)

	if n.IsChunkedManifest() {
		chunkManifest, e := operation.LoadChunkManifest(n.Data, n.IsGzipped())
		if e != nil {
			writeJsonError(w, r, http.StatusInternalServerError, fmt.Errorf("Load chunks manifest error: %v", e))
			return
		}
		// make sure all chunks had deleted before delete manifest
		if e := chunkManifest.DeleteChunks(vs.GetMasterNode(), r.FormValue("collection")); e != nil {
			writeJsonError(w, r, http.StatusInternalServerError, fmt.Errorf("Delete chunks error: %v", e))
			return
		}
		count = chunkManifest.Size
	}

	ret := topology.ReplicatedDelete(vs.GetMasterNode(), vs.store, volumeId, n, r)

	if ret != 0 {

示例2: batchDeleteHandler

			ret = append(ret, operation.DeleteResult{
				Fid:    fid,
				Status: http.StatusBadRequest,
				Error:  err.Error()})
			continue
