Question about onsChannel param

[messense]

What does onsChannel param mean in setSessionCredentials method?

rocketmq-client-cpp/include/MQClient.h

Lines 174 to 176 in a42078d

	void setSessionCredentials(const std::string& input_accessKey,
	const std::string& input_secretKey,
	const std::string& input_onsChannel);

This method provides the ability to connect some cloud platform with your AK, SK using a specific signature, such as aliyun and so on. eg, "ALIYUN" should be set to the Channel when connecting to aliyun platform and the c style API is recommend to use like ROCKETMQCLIENT_API int SetProducerSessionCredentials(CProducer *producer, const char *accessKey, const char *secretKey,const char *onsChannel);

If I setup authentication for my local RocketMQ instance, can I use setSessionCredentials method? How should I pass onsChannel param in that case?

[ShannonDing]

Just leave them none, if you wanna connect local broker without authentication.

Did you mean with authentication?

@ShannonDing I think you should make some clear when supporting some cloud service.

1. Connect Aliyun: please fulfill the paras with AK, SK and "ALIYUN",
2. Connect local broker without authentication: leave all the paras of SessionCredentials none,
3. Connect local broker with authentication: using AK, SK, and your signature method name instead now,
4. Other could platform: not support now

@ShannonDing Thanks!
