I have trying to write a function that will accept a string as an input and
return another string in a slice but it not working. I have function that
unmarshal udp response to a type AuthVectors and then append the type
struct data into an array authVecSlice. Below is the code
type AuthVectors struct {
MessageType string `json:"message_type"`
IMSI string `json:"IMSI"`
RAND string `json:"RAND"`
XRES string `json:"XRES"`
AUTN string `json:"AUTN"`
}
var imsistr = "244340000000011"
var authVecSlice = make([]AuthVectors, 10)
func getAuthVec() {
hostName := "localhost"
portNum := "4343"
service := hostName + ":" + portNum
RemoteAddr, err := net.ResolveUDPAddr("udp", service)
conn, err := net.DialUDP("udp", nil, RemoteAddr)
if err != nil {
log.Fatal(err)
}
defer conn.Close()
// write a message to server
_, err = conn.Write([]byte(imsistr))
if err != nil {
log.Println(err)
}
// receive message from server
buffer := make([]byte, 1024)
i, _, err := conn.ReadFromUDP(buffer)
checkError(err)
err = json.Unmarshal(buffer[:i], &avs)
if err != nil {
panic(err)
}
authVecSlice = append(authVecSlice, avs)
fmt.Println(authVecSlice)
}
The array out put is as follows
[{AUTN_PARAM 244340000000011 C98FC7C6DE9E1351A397D0AF99B6E890
D857E39D57E5E6BE 8000...} {AUTN_PARAM 244340000000011
211B025CB1CC8EE9CBB5FC7F56C1506B C9396A5AC7E68D62 31D...} {AUTN_PARAM
244340000000011 7D2A8C6E6B5CA243278987DFAF7FC829 C9EE960D0F5A501A 7E8..}
...]
I would like to use the field RAND to search and return the corresponding
XRES in the array. For example in the array is
{AUTN_PARAM 244340000000011 C98FC7C6DE9E1351A397D0AF99B6E890
D857E39D57E5E6BE 8000...}
I would like to use the RAND value for example
C98FC7C6DE9E1351A397D0AF99B6E890 as a search string and return its
corresponding XRES D857E39D57E5E6BE.
func getXRES(a []AuthVectors, x interface{}) (xres string) {
for _, v := range a {
if x == v {
xres := v.XRES
return xres
}
}
return "Item not found"
}
The problem for me is that the array value do not have key to be use to
perform the search. All example I found involves the use of key to fetch
the values. Any help
