go - 如何将特定 channel 分配给空接口(interface) channel

Question

如果我有一个空的接口(interface) channel 类型，我只想监视事件，并且想根据需要为其分配特定的 channel ，那么在 Golang 中是否可行？

myChan := make(chan interface{})
confirms := ch.NotifyPublish(make(chan amqp.Confirmation, 1))
myChan = confirms // (<- cannot use type chan Confirmation in type chan interface{} assignment

Answer 1

您可以将 channel 本身作为空接口(interface)传递，然后在另一端解析它。

confirms := ch.NotifyPublish(make(chan amqp.Confirmation, 1))
var mychanpointerpointer interface{}
mychanpointerpointer = confirms
.
.
.
switch mychanpointer := mychanpointerpointer.(type) {
case chan amqp.Confirmation:
    fmt.Println("GOT A CONFIRMATION CHANNEL:", mychanpointer)
}

输出: GOT A CONFIRMATION CHANNEL: 0xc42016a000
