开始学习golang.任务:获取Json和Unmarshall.但我错了:

Json tag but not exported

如何导出未导出的字段,然后使用方法实现它？

这是代码:

package main

import (
    "encoding/json"
    "fmt"
    "io/ioutil"
    "net/http"
)

type Time struct {
    time
}
type time struct {
    id                    string  `json:"$id"`
    currentDateTime       string  `json:"currentDateTime,string"`
    utcOffset             float64 `json:"utcOffset,string"`
    isDayLightSavingsTime bool    `json:"isDayLightSavingsTime,string"`
    dayOfTheWeek          string  `json:"dayOfTheWeek,string"`
    timeZoneName          string  `json:"timeZoneName,string"`
    currentFileTime       float64 `json:"currentFileTime,string"`
    ordinalDate           string  `json:"ordinalDate,string"`
    serviceResponse       string  `json:"serviceResponse,string"`
}

func (t *Time) GetTime() (Time, error) {
    result := Time{}

    return result, t.Timenow(result)
}
func (t *Time) Timenow(result interface{}) error {

    res, err := http.Get("http://worldclockapi.com/api/json/utc/now") …

我有

array1 = [1,2,3,4,5];
array2 = ["one","two","three","four","five"];

我希望得到第一个(和其他)元素等array3所有元素的位置.array1array2

例如:

array3 = ["one 1", "two 1", "three 1", "four 1", "five 1", "one 2", "two 2", "three 2", "four 2", "five 2"...]

我知道我需要使用for循环,但我不知道该怎么做.
