Constants

const (
	ExchangeDirect  = "direct"
	ExchangeFanout  = "fanout"
	ExchangeTopic   = "topic"
	ExchangeHeaders = "headers"
)

Constants for standard AMQP 0-9-1 exchange types.

const (
	Transient  uint8 = 1
	Persistent uint8 = 2
)

DeliveryMode. Transient means higher throughput but messages will not be restored on broker restart. The delivery mode of publishings is unrelated to the durability of the queues they reside on. Transient messages will not be restored to durable queues, persistent messages will be restored to durable queues and lost on non-durable queues during server restart.

This remains typed as uint8 to match Publishing.DeliveryMode. Other delivery modes specific to custom queue implementations are not enumerated here.

const (
	LevelEmergency = iota
	LevelAlert
	LevelCritical
	LevelError
	LevelWarning
	LevelNotice
	LevelInformational
	LevelDebug

Client rabbitmq客户端信息

func NewClient

func NewClient() *Client

NewClient 创建一个默认的客户端信息

func (*Client) GetPublishStatus

func (c *Client) GetPublishStatus() bool

GetPublishStatus 获取生产者状态

func (*Client) Identity

func (c *Client) Identity() string

Identity returns the same host/process unique string for the lifetime of this process so that subscriber reconnections reuse the same queue name.

func (*Client) Info

func (c *Client) Info()

Info 客户端配置信息

func (*Client) SetDeliveryMode

func (c *Client) SetDeliveryMode(dMode uint8)

SetDeliveryMode 设置消息投递模式

func (c *Client) SetExpirationTime(time int32)

SetExpirationTime 设置消息过期时间, 单位ms

func (*Client) SetMsgExpirationEnable

func (c *Client) SetMsgExpirationEnable(enable bool)

SetMsgExpirationEnable 设置消息是否过期

func (*Client) SetPublishStatus

func (c *Client) SetPublishStatus(status bool)

SetPublishStatus 设置生产者状态

func (*Client) SetQos

func (c *Client) SetQos(qos int)

SetQos 设置Qos值

func (*Client) SetQueueBindEnable

func (c *Client) SetQueueBindEnable(enable bool)

SetQueueBindEnable 设置是否需要声明和绑定到交换器

func (*Client) SetQueueName

type Message

type Message []byte

Message is the application type for a message. This can contain identity, or a reference to the recevier chan for further demuxing.

type MessageWithRoutingKey

type MessageWithRoutingKey struct {
	RoutingKey string
	Message    []byte
}

MessageWithRoutingKey is the application type for a message with routing key

type Session

type Session struct {
	*amqp.Connection
	*amqp.Channel
}

Session composes an amqp.Connection with an amqp.Channel

func (Session) Close

func (s Session) Close() error

Close tears the connection down, taking the channel with it.

type TraceFunc

type TraceFunc func(format string, level int, v ...interface{})

var UserTrace TraceFunc = nil
