Thanks https://github.com/huandu/go-tls for original idea
- get current goroutine id
- goroutine local storage
require go version >= 1.4
get the identifier unique for this goroutine
go func() {
gls.GoID()
}()
go func() {
gls.GoID()
}()goroutine local storage is a map[interface{}]interface{} local to current goroutine
It is intended to be used by framworks to simplify context passing.
Use context.Context to pass context if possible.
gls.Set("user_id", "abc")
doSomeThing()
func doSomeThing() {
gls.Get("user_id") // will be "abc"
}
