想让go返回的时间是”YYYY-MM-DD HH:ii:ss”的格式，但是他始终返回为2006-01-02T15:04:05Z07:00。
查看源代码后发现，go的时间format里面封装了下面这些时间格式

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 |
const ( ANSIC = "Mon Jan _2 15:04:05 2006" UnixDate = "Mon Jan _2 15:04:05 MST 2006" RubyDate = "Mon Jan 02 15:04:05 -0700 2006" RFC822 = "02 Jan 06 15:04 MST" RFC822Z = "02 Jan 06 15:04 -0700" // RFC822 with numeric zone RFC850 = "Monday, 02-Jan-06 15:04:05 MST" RFC1123 = "Mon, 02 Jan 2006 15:04:05 MST" RFC1123Z = "Mon, 02 Jan 2006 15:04:05 -0700" // RFC1123 with numeric zone RFC3339 = "2006-01-02T15:04:05Z07:00" RFC3339Nano = "2006-01-02T15:04:05.999999999Z07:00" Kitchen = "3:04PM" // Handy time stamps. Stamp = "Jan _2 15:04:05" StampMilli = "Jan _2 15:04:05.000" StampMicro = "Jan _2 15:04:05.000000" StampNano = "Jan _2 15:04:05.000000000" ) |
没有发现我需要的时间格式，始终返回RFC3339格式的2006-01-02T15:04:05Z07:00格式
查看了json对于时间的格式化方法，实现下面的接口
