golang踩坑集锦

1、项目实践中踩的坑

• Golang中time.Parse和time.Format的时区问题

    timeNow:=time.Now()//2020-04-26 19:33:25
    timeStamp:="2020-04-26 19:32:25"
    dataFormat:="2006-01-02 15:04:05"
    tLast, _ := time.Parse(dataFormat, timeStamp)
    res:=timeNow.Before(tLast)//返回的居然是true，一脸懵逼

• Go by Example: Range

   var  name, pwd string
    //pwdRune := []rune(pwd)
    length := len(pwd)
    //length := len(pwdRune)
    for i, v := range name {
        if pwd[length-i-1] != v {
            return false
        }
    }//切片越界

• syntax error: non-declaration
• syntax error: non-declaration

    //syntax error: non-declaration statement outside function body
    AlarmRecordCache, _ := cache.NewCache("memory", `{"interval":0}`)
    //这样是可以的
    var AlarmRecordCache, _ = cache.NewCache("memory", `{"interval":0}`)
