Unable to access values from Pointer receiver - pointers

Question

I'm unable to get value from Pointer receiver. It keeps returning memory address.
I'm trying to access values from the pointer receivers from other file in this below format
package types
import (
// "Some product related imports"
"golang.org/x/oauth2"
"time"
)
type TestContext struct {
userId string
}
func (cont *TestContext) GetUserId() string {
return cont.userId
}
I'm trying to solve it through multiple ways but either getting memory address, nil values or error.

Answer 1

Always write clean code:
Name userID not userId.
Name UserID() not GetUserId().
use ctx2 := &myType.myType{} instead of ctx2 := *myType.myType{}.
try this code:
package main
import (
"fmt"
)
type myType struct {
userID string
}
func (cont *myType) UserID() string {
return cont.userID
}
func main() {
ctx1 := myType{"1"}
fmt.Println(ctx1.UserID()) // 1
ctx := myType{"2"}
var101 := ctx.UserID()
fmt.Println(ctx1.UserID(), var101) // 1 2
ctx2 := &myType{}
fmt.Println(ctx2) // &{}
var ctx3 *myType
fmt.Println(ctx3) // <nil>
}
Output:
1
1 2
&{}
<nil>

For Technique 1. I'm not sure what logging.Debug() does but I think you are trying to pass a string to it. In this case use ctx2.GetUserId() not ctx2.GetUserId. I know it's sounds silly but to call a function that takes no parameters you still need the brackets.
The major problem is that you are using the myType package but you think you are using the types package. Otherwise I think technique 2 would be OK.
And as Volker implied about tehcnique 3 you need to use & not * to take the address of an object.
