Function OptionalStringArrayParam

pkg/github/params.go:245–269

OptionalStringArrayParam is a helper function that can be used to fetch a requested parameter from the request. It does the following checks: 1. Checks if the parameter is present in the request, if not, it returns its zero-value 2. If it is present, iterates the elements and checks each is a string

(args map[string]any, p string)

// 1. Checks if the parameter is present in the request, if not, it returns its zero-value
// 2. If it is present, iterates the elements and checks each is a string
func OptionalStringArrayParam(args map[string]any, p string) ([]string, error) {
	// Check if the parameter is present in the request
	if _, ok := args[p]; !ok {
		return []string{}, nil
	}

	switch v := args[p].(type) {
	case nil:
		return []string{}, nil
	case []string:
		return v, nil
	case []any:
		strSlice := make([]string, len(v))
		for i, v := range v {
			s, ok := v.(string)
			if !ok {
				return []string{}, fmt.Errorf("parameter %s is not of type string, is %T", p, v)
			}
			strSlice[i] = s
		}
		return strSlice, nil
	default:
		return []string{}, fmt.Errorf("parameter %s could not be coerced to []string, is %T", p, args[p])
	}
}
