Extracting values from []interface{} – Getting Assist

Hello All,

I’m studying golang and wish some assist please.

i’ve a variable transformedEmail that appears like this when printed::

fmt.Printf("debug: %T, %v", transformedEmail, transformedEmail)

debug: []interface {}, [map[encoded_value:.YlGhCqAs@gmail.com] map[encoded_value:+61-442-291-954] map[encoded_value:9872-5721-5683-2126] map[encoded_value:830-726 79679125]]%

I need to loop via it and get the worth of every “encoded_value”, how might I do it?

Thanks

I’ve

I’ve tried to make use of transformedEmail[0] however I get following error:

invalid operation: can not index transformedEmail (variable of kind interface{})compilerNonIndexableOperand

Your transformedEmail should have been declared as kind interface{}. The %T let you know its dynamic kind is []interface{}. Use a sort assertion to get the slice variable you can index.

  transformedEmailSlice,okay := transformedEmail.([]interface{})
  if !okay {
    log.Fatalf("transformedEmail shouldn't be actually a []interface{}")
  }
  for i, aspect := vary transformedEmailSlice {
    fmt.Printf("transformedEmail aspect %d: %T %vn",i,aspect,aspect)
  }
