time.Parse() 不会使用系统本地时区解析指定时区解析时间字符串为Time，需要使用： time.ParseInLocation() timeZone, _ := time.LoadLocation("Asia/Shanghai") timeObj_1, _ := time.Parse("2006-01-02 15:04:05", "2020-12-01 00:00:00") fmt.Println("timeObj_1" , timeObj_1.Unix()) timeObj_2 ,

获取数值的格式的年月日package mainimport ( "fmt" "time")func main() { month := time.Unix(1557042972, 0).Format("1") fmt.Println(month) year := time.Now().Format("2006") month = time.Now().Format("01") day := time.Now().Format("02") fmt.Println(year).

package mainimport ( "flag" "fmt" )func main() { var name string var age int64 flag.StringVar(&name,"name","default","log in user") flag.Int64Var(&age, "age", 16, "help message for flagname") // 必须有这一行 flag.Parse() fmt.Println( ref

array打印结果可知item传的是引用func main() { item := make( map[string]interface{} ) var array [3]interface{} item["key"] = 2 var i int item["key"] = 1 array[i] = item for i=0; i<3; i++ { item["key"] = i+10 fmt.Println(item) array[i] = item } fmt.P

先贴出PHP代码：$string = "1234";$key = "abcd";$signature = hash_hmac('sha256', $string, $key);然后是Golang：package mainimport ( "crypto/hmac" "crypto/sha256" "encoding/hex" "fmt")func main() { ...
