问题
我正在尝试从Excel电子表格中提取日期，我已经成功获取到一个包含完整日期的日志，我想知道如何只提取月份。例如，在这种情况下，日志中是这样写的："log.Println("DT REFER", emp.DT_REFER)"，其中DT_REFER是电子表格中的日期，我该如何只提取月份？日期的格式是这样的：DT REFER 2011-03-31。

I'm trying to extract a date from an excel spreadsheet, I managed to give a log where it shows the entire date, I wanted to know how to extract only the month, for example, in this case it's "log.Println("DT REFER", emp. DT_REFER" the DT_REFER is where the date is in the spreadsheet, how can I get only the month out of it? the format that came was this.
DT REFER 2011-03-31

你可以使用fmt.Sscanf来从你的日志字符串中提取月份。假设你有一个固定的字符串结构可以进行匹配，代码如下：
// 如果emp.DT_REFER不是字符串，请使用Sprint将其转换为字符串
s := fmt.Sprint(emp.DT_REFER)
y, m, d := 0, 0, 0
fmt.Sscanf(s, "%d-%d-%d", &y, &m, &d)
fmt.Println(y, m, d)
英文:
You can use fmt.Sscanf to extract the month out of the log string that you have. Given you have a fixed string structure that you can match against as follows:
// if emp.DT_REFER isn't string use Sprint to make it string
s := fmt.Sprint(emp.DT_REFER)
y, m, d := 0, 0, 0
fmt.Sscanf(s, "%d-%d-%d", &y, &m, &d)
fmt.Println(y, m, d)
