I have a string that I want to convert into an array.

str := "[\"firsName\",\"lastName\", \"email\"]"
fmt.Println(reflect.TypeOf(str))
fmt.Println(strings.Split(str, ","))

This results:

[["firsName" "lastName"  "email"]]

I want the output like this:

["firsName" "lastName"  "email"]

I can get this by using strings.Replace function. But is there any better way to do this?

CodePudding user response：

You can use strings.Trim to remove the trailing and leading unwanted character.

trimmedStr := strings.Trim("[\"firsName\",\"lastName\", \"email\"]", "[]")
fmt.Println(strings.Split(trimmedStr, ","))

str := "[\"firsName\",\"lastName\", \"email\"]"
var strArr []string
_ = json.Unmarshal([]byte(str), &strArr)
fmt.Println(strArr)
