Functions

func GetTagString

func GetTagString(tag *string) string

func MixTags

func MixTags(tags ...string) string

func MustSetUp

func MustSetUp(config *Config)

func NewProducer

func NewProducer() (rmq_client.Producer, error)

NewProducer

PS: In most case, you don't need to create many producers, singletion pattern is more recommended.

@param clientLogPath 客户端日志（blank则输出到控制台）

func NewSimpleConsumer

func NewSimpleConsumer(consumerGroup string, subscriptionExpressions map[string]*rmq_client.FilterExpression) (rmq_client.SimpleConsumer, error)

NewSimpleConsumer

PS: In most case, you don't need to create many consumers, singletion pattern is more recommended.

@param consumerGroup 不能为"" @param subscriptionExpressions (1) key: topic，不能为 "*" || blank

(2) value: 	tag，一般为 rmq_client.SUB_ALL

@param clientLogPath 客户端日志（blank则输出到控制台）

func SendMessage

func SendMessage(producer rmq_client.Producer, ctx context.Context, topic string, tag *string, body []byte, messageGroup string, deliveryTimestamp time.Time, keys ...string) ([]*rmq_client.SendReceipt, error)

SendMessage Deprecated: 仅供参考如何生产消息

func SetUp

func SetUp(c *Config) error
