-## golang 重复提交和流量限制
-
-
-### 写的比较粗糙，有错误的地方希望指正
-
-``` go
-//LimitInfo 限制对象
-type LimitInfo struct {
-    Time      int64
-    Count     int64
-    Name      string
-    LimitType int    //1 流量控制，2 并发控制
-    LimitKey  string //限制key
-}
-
-
-//Limit 限制方法
-func (l *LimitInfo) Limit() bool {
-    limit := true
-    key := "limit-key-" + l.LimitKey
-    c := redisutil.Pool.Get()
-    defer c.Close()
-    result, errRedis := c.Do("Incr", key)
-    if errRedis != nil {
-        log.Info(l.Name, " ,key:", key, ", errRedis=[", errRedis, "]")
-        limit = false
-    }
-    count, errorcase := redis.Int64(result, nil)
-    if errorcase != nil {
-        log.Info(l.Name, " ,key:", key, " ,errorcase=[", errorcase, "]")
-        limit = false
-    }
-    if l.LimitType == 1 { //LimitType 1 是流量控制
-        if count == 1 {
-            if _, errExpire := c.Do("expire", key, l.Time); errExpire != nil {
-                log.Info(l.Name, " ,key:", key, " ,errExpire=[", errExpire, "]")
-                limit = false
-            }
-        }
-    } else if l.LimitType == 2 { //LimitType 2 是并发控制，防重复提交
-        if _, errExpire := c.Do("expire", key, l.Time); errExpire != nil {
-            log.Info(l.Name, " ,key:", key, " ,errExpire=[", errExpire, "]")
-            limit = false
-        }
-    } else {
-        //未做限制
-        limit = true
-    }
-    if count > l.Count {
-        limit = false
-        log.Info(l.Name, " ,key:", key, " ,err=[out limit] ,limit:", l.Count)
-    }
-    return limit
-}
-```
-
-### 使用如下：
-
-``` go 
-redisutil.Pool = redisutil.NewPool(*redisutil.RedisServer)
-    info := &LimitInfo{
-        //10秒
-        Time:      10,
-        Count:     10,
-        Name:      "请求限制0001",
-        LimitType: 1,
-        LimitKey:  "aaronwei-tensec-",
-    }
-info.Limit()
-```
