示例1: getResponse

// getResponse decodes a http.Response to create a cmds.Response
func getResponse(httpRes *http.Response, req cmds.Request) (cmds.Response, error) {
	var err error
	res := cmds.NewResponse(req)

	contentType := httpRes.Header.Get(contentTypeHeader)
	contentType = strings.Split(contentType, ";")[0]

	lengthHeader := httpRes.Header.Get(extraContentLengthHeader)
	if len(lengthHeader) > 0 {
		length, err := strconv.ParseUint(lengthHeader, 10, 64)
		if err != nil {
			return nil, err
		}
		res.SetLength(length)
	}

	rr := &httpResponseReader{httpRes}
	res.SetCloser(rr)

	if contentType != applicationJson {
		// for all non json output types, just stream back the output
		res.SetOutput(rr)
		return res, nil

	} else if len(httpRes.Header.Get(channelHeader)) > 0 {
		// if output is coming from a channel, decode each chunk
		outChan := make(chan interface{})

		go readStreamedJson(req, rr, outChan)

		res.SetOutput((<-chan interface{})(outChan))
		return res, nil
	}

	dec := json.NewDecoder(rr)

	// If we ran into an error
	if httpRes.StatusCode >= http.StatusBadRequest {
		e := cmds.Error{}

		switch {
		case httpRes.StatusCode == http.StatusNotFound:
			// handle 404s
			e.Message = "Command not found."
			e.Code = cmds.ErrClient
