# VSCode 调试程序 Scanf 无法输入问题
|
||||
|
||||
VSCode 调试 C/C++/Golang 等程序时，遇到 fmt.Scan/fmt.Scanf/fmt.Scanln 等输入时，在 Debug Console 中是无法输入的。
|
||||
|
||||
解决办法是在调试的 launch.json 中添加："console": "integratedTerminal"，如下：
|
||||
|
||||
```json
|
||||
{
|
||||
// ...
|
||||
"configurations": [
|
||||
// ...
|
||||
{
|
||||
// ...
|
||||
"console": "integratedTerminal",
|
||||
// ...
|
||||
},
|
||||
// ...
|
||||
],
|
||||
// ...
|
||||
}
|

```

还可以使用 Golang 预先设定好的 Layout 风格：
|
||||
|
||||
```go
|
||||
now := time.Now()
|
||||
fmt.Println(now) // 2009-11-10 23:00:00 +0000 UTC m=+0.000000001
|
||||
fmt.Println(now.Format(time.Layout)) // 01/02 03:04:05PM '06 -0700
|
||||
fmt.Println(now.Format(time.ANSIC)) // Mon Jan _2 15:04:05 2006
|
||||
fmt.Println(now.Format(time.UnixDate)) // Mon Jan _2 15:04:05 MST 2006
|
||||
fmt.Println(now.Format(time.RubyDate)) // Mon Jan 02 15:04:05 -0700 2006
|
||||
fmt.Println(now.Format(time.RFC822)) // 02 Jan 06 15:04 MST
|
||||
fmt.Println(now.Format(time.RFC850)) // Monday, 02-Jan-06 15:04:05 MST
|
||||
fmt.Println(now.Format(time.Kitchen)) // 3:04PM
|
||||
fmt.Println(now.Format(time.Stamp)) // Jan _2 15:04:05
|
||||
```
|
||||
|
||||
定义在 time 包的 format.go 文件中：
|
||||
|
||||
```go
|
||||
// These are predefined layouts for use in Time.Format and time.Parse.
|
||||
// The reference time used in these layouts is the specific time stamp:
|
||||
//
|
||||
// 01/02 03:04:05PM '06 -0700
|
||||
//
|
||||
// (January 2, 15:04:05, 2006, in time zone seven hours west of GMT).
|
||||
// That value is recorded as the constant named Layout, listed below. As a Unix
|
||||
// time, this is 1136239445. Since MST is GMT-0700, the reference would be
|
||||
// printed by the Unix date command as:
|
||||
//
|
||||
// Mon Jan 2 15:04:05 MST 2006
|
||||
//
|
||||
// It is a regrettable historic error that the date uses the American convention
|
||||
// of putting the numerical month before the day.
|
||||
//
|
||||
// The example for Time.Format demonstrates the working of the layout string
|
||||
// in detail and is a good reference.
|
||||
//
|
||||
// Note that the RFC822, RFC850, and RFC1123 formats should be applied
|
||||
// only to local times. Applying them to UTC times will use "UTC" as the
|
||||
// time zone abbreviation, while strictly speaking those RFCs require the
|
||||
// use of "GMT" in that case.
|
||||
// In general RFC1123Z should be used instead of RFC1123 for servers
|
||||
// that insist on that format, and RFC3339 should be preferred for new protocols.
|
||||
// RFC3339, RFC822, RFC822Z, RFC1123, and RFC1123Z are useful for formatting;
|
||||
// when used with time.Parse they do not accept all the time formats
|
||||
// permitted by the RFCs and they do accept time formats not formally defined.
|
||||
// The RFC3339Nano format removes trailing zeros from the seconds field
|
||||
// and thus may not sort correctly once formatted.
|
||||
//
|
||||
// Most programs can use one of the defined constants as the layout passed to
|
||||
// Format or Parse. The rest of this comment can be ignored unless you are
|
||||
// creating a custom layout string.
|
||||
//
|
||||
// To define your own format, write down what the reference time would look like
|
||||
// formatted your way; see the values of constants like ANSIC, StampMicro or
|
||||
// Kitchen for examples. The model is to demonstrate what the reference time
|
||||
// looks like so that the Format and Parse methods can apply the same
|
||||
// transformation to a general time value.
|
||||
//
|
||||
// Here is a summary of the components of a layout string. Each element shows by
|
||||
// example the formatting of an element of the reference time. Only these values
|
||||
// are recognized. Text in the layout string that is not recognized as part of
|
||||
// the reference time is echoed verbatim during Format and expected to appear
|
||||
// verbatim in the input to Parse.

// "-070000" ±hhmmss
|
||||
// "-07:00:00" ±hh:mm:ss
|
||||
//
|
||||
// Replacing the sign in the format with a Z triggers
|
||||
// the ISO 8601 behavior of printing Z instead of an
|
||||
// offset for the UTC zone. Thus:
|
||||
//
|
||||
// "Z0700" Z or ±hhmm
|

// "Z07:00" Z or ±hh:mm

// Within the format string, the underscores in "_2" and "__2" represent spaces
