示例1: WriteResponse

// 回複消息給微信服務器.
//  要求 msg 是有效的消息數據結構(經過 encoding/xml marshal 後符合消息的格式);
//  如果有必要可以修改 Request 裏麵的某些值, 比如 TimeStamp.
func WriteResponse(w http.ResponseWriter, r *Request, msg interface{}) (err error) {
	if w == nil {
		return errors.New("nil http.ResponseWriter")
	}
	if r == nil {
		return errors.New("nil Request")
	}
	if msg == nil {
		return errors.New("nil message")
	}

	MsgRawXML, err := xml.Marshal(msg)
	if err != nil {
		return
	}

	EncryptedMsg := util.AESEncryptMsg(r.Random, MsgRawXML, r.CorpId, r.AESKey)
	base64EncryptedMsg := base64.StdEncoding.EncodeToString(EncryptedMsg)

	responseHttpBody := ResponseHttpBody{
		EncryptedMsg: base64EncryptedMsg,
		TimeStamp:    r.TimeStamp,
		Nonce:        r.Nonce,
	}

	TimestampStr := strconv.FormatInt(responseHttpBody.TimeStamp, 10)
	responseHttpBody.MsgSignature = util.MsgSign(r.AgentToken, TimestampStr,
		responseHttpBody.Nonce, responseHttpBody.EncryptedMsg)

	return xml.NewEncoder(w).Encode(&responseHttpBody)
