最近在学习micro框架的时候，遇到了下面这个问题：lcx@ubuntu:~/lhome$ micro run .Error creating stream: rpc error: code = Unavailable desc = connection error: desc = "transport: Error while dialing dial tcp 127.0.0.1:8081: connect: connection refused"出现这个错误的原因是，没有登陆micro：#首先

package mainimport ( "fmt" "io" "net/http" "os" "regexp" "strconv" "strings")func formatStr(str* string) { switch len(*str) { case 3: *str=*str+"\t\t\t\t" case 6: *str=*str+"\t\t\t\t" case 7: *str=*str+"\t\t\t\t" case 8: *str=*str+

GO语言实现生产者消费者模型一、只使用Channel实现package mainimport ( "fmt" "math/rand" "sync" "time")//生产者函数func producter(index int,ch chan<- int){ for { //获得1~1000的随机数 num:=rand.Intn(1000) //将随机数写入Channel中 ch<-num
