I have a raw string which is formed from array of strings like the one defined below
"['a','b','c']"
which i want to convert to proper array of string as below
["a","b","c"]
I am trying this on golang. However, i didn't succeed in getting this done. How this can be accomplished in go
var s = "['a','b','c']"
ss := strings.Split(strings.Trim(s, "[]"), ",")
a := make([]string, len(ss))
for i := range ss {
a[i] = strings.Trim(ss[i], "'")
}
out, err := json.Marshal(a)
if err != nil {
panic(err)
}
fmt.Println(string(out))
// output: ["a","b","c"]

if i have many option to be filter in IF statement, can i use some function like this?
s1 := "lorem ipsum"
sum := 0
for _, v := range s1 {
if string(v) like ("a","i","u","e","o") {
sum+=1
}
}
You can use switch statement.
Switch supports multiple matches
switch string(v) {
case "a","i","u","e","o":
sum+=1
}
Tried it in the playground - https://play.golang.org/p/QRYhEDA7EUZ

I want to parse and get url from a string such as hello google.comxxx，the output should be google.com, is there any easy way to do that?
There's a package named xurls which you can use.
import "mvdan.cc/xurls/v2"
func main() {
rxRelaxed := xurls.Relaxed()
rxRelaxed.FindString("Do gophers live in golang.org?") // "golang.org"
rxRelaxed.FindString("This string does not have a URL") // ""
rxStrict := xurls.Strict()
rxStrict.FindAllString("must have scheme: http://example.com/.", -1) // []string{"http://example.com/"}
rxStrict.FindAllString("no scheme, no match: example.com", -1) // []string{}
}

I'm thinking up about how I find the same characters in one variable looks like this:
var words string = "abab"
and then I want's to eliminate the same characters in that one variable and here's the output to be
Output:
ab
have any solution about this?
One solution can be the use of go map[] to track the taken characters.
sample code:
func main() {
s := "abcdaabcefgahccij"
newS := ""
taken := make(map[rune]int)
for _, value := range s {
if _, ok := taken[value]; !ok {
taken[value] = 1
newS += string(value)
}
}
fmt.Println(newS)
}
Output:
abcdefghij

I have written a golang program to generate the start date and end date of the month for different locations
if month != "" && year != "" {
var monthInt, _ = strconv.Atoi(month)
var yearInt, _ = strconv.Atoi(year)
timeZone, err := time.LoadLocation("America/Pheonix")
if err != nil {
fmt.Println(err)// nil
}
// currentLocation := time.Now().Location(timeZone) // when I use this it will works
// both are of same type
fmt.Println(reflect.TypeOf(timeZone))
fmt.Println(reflect.TypeOf(time.UTC))
firstOfMonth := time.Date(yearInt, time.Month(monthInt), 1, 0, 0, 0, 0, timeZone)
onlyStartDate := strings.Split(firstOfMonth.Format("2006-01-02 00:00:00 -0000"), " ")
lastOfMonth := firstOfMonth.AddDate(0, 1, -1).Format("2006-01-02 00:00:00 -0000")
onlyLastDate := strings.Split(lastOfMonth, " ")
merchantDb.GetProvidersOfTheMonth(onlyStartDate[0], onlyLastDate[0])
}
But when I run this code it will give me the error of the:-
time: missing Location in call to Date
Why this error is generating and how I will solve this error?
Please any suggestions!
It should be America/Phoenix, not America/Pheonix.
timeZone, _ := time.LoadLocation("America/Phoenix")
