英文:
Can we use select to Accept() from different listeners in Go?
问题
就像以下代码一样：
for {select {case conn, err := listener1.Accept():if err != nil {log.Fatal(err)}go handleConn1(conn)case conn, err := listener2.Accept():if err != nil {log.Fatal(err)}go handleConn1(conn)}}
当编辑器告诉我select有问题时，我们能在Go中实现类似这样的代码吗？
英文:
Just as the following codes:
for {select {case conn, err := listener1.Accept():if err != nil {log.Fatal(err)}go handleConn1(conn)case conn, err := listener2.Accept():if err != nil {log.Fatal(err)}go handleConn1(conn)}}
While the editor tells me something wrong with select
Can we implement something like this in Go?

select只能用于通道（在这里了解更多：https://gobyexample.com/select）
在你的情况下，你可以创建两个goroutine，每个goroutine等待一个监听器的Accept并处理连接：
go func() {for {conn, err := listener1.Accept()if err != nil {log.Fatal(err)}handleConn1(conn)}}()go func() {for {conn, err := listener2.Accept()if err != nil {log.Fatal(err)}handleConn2(conn)}}()
英文:
select only works with channels (see more here: https://gobyexample.com/select)
In your case, you could span two goroutines so that each of them waits for the Accept of one listener and processes the connection:
go func() {for {conn, err := listener1.Accept():if err != nil {log.Fatal(err)}handleConn1(conn)}}()go func () {for {conn, err := listener2.Accept():if err != nil {log.Fatal(err)}handleConn2(conn)}}()
