将局部变量的指针传递给 Golang 中的通道是否安全？ | 那些遇到过的问题

noh*_*hup 5 stack struct pointers go

我有一个代码块，用于查询 AD 并检索结果并写入通道。

func GetFromAD(connect *ldap.Conn, ADBaseDN, ADFilter string, ADAttribute []string, ADPage uint32) *[]ADElement {

    searchRequest := ldap.NewSearchRequest(ADBaseDN, ldap.ScopeWholeSubtree, ldap.NeverDerefAliases, 0, 0, false, ADFilter, ADAttribute, nil)
    sr, err := connect.SearchWithPaging(searchRequest, ADPage)
    CheckForError(err)
    fmt.Println(len(sr.Entries))
    ADElements := []ADElement{} 
    for _, entry := range sr.Entries{
        NewADEntity := new(ADElement) //struct
        NewADEntity.DN = entry.DN
        for _, attrib := range entry.Attributes {
            NewADEntity.attributes = append(NewADEntity.attributes, keyvalue{attrib.Name: attrib.Values})
        }
        ADElements = append(ADElements, *NewADEntity)
    }
    return &ADElements
}

[]ADElements

initialrun

ADElements := GetFromAD(connectAD, ADBaseDN, ADFilter, ADAttribute, uint32(ADPage))
fmt.Println(reflect.TypeOf(ADElements))
ADElementsChan <- ADElements

输出说

*[]somemodules.ADElement

reflect.TypeOf

ADElements := []ADElement{}GetFromAD()GetFromAD()GetFromAD()GetFromAD()
