+## golang ID混淆
|
|
|
+
|
|
|
+### 用命令获取第三方包
|
|
|
+
|
|
|
+```bash
|
|
|
+go get -u -v github.com/speps/go-hashids
|
|
|
+
|
|
|
+```
|
|
|
+
|
|
|
+### 实现如下
|
|
|
+
|
|
|
+```go
|
|
|
+package hashids
|
|
|
+
|
|
|
+import (
|
|
|
+ "github.com/speps/go-hashids"
|
|
|
+)
|
|
|
+
|
|
|
+//salt 盐值
|
|
|
+const salt = "salt"
|
|
|
+
|
|
|
+//Encode 混淆
|
|
|
+func Encode(data int) string {
|
|
|
+ hd := hashids.NewData()
|
|
|
+ hd.Salt = salt
|
|
|
+ h, _ := hashids.NewWithData(hd)
|
|
|
+ e, _ := h.Encode([]int{data})
|
|
|
+ return e
|
|
|
+}
|
|
|
+
|
|
|
+//Decode 还原混淆
|
|
|
+func Decode(data string) int {
|
|
|
+ hd := hashids.NewData()
|
|
|
+ hd.Salt = salt
|
|
|
+ h, _ := hashids.NewWithData(hd)
|
|
|
+ e, _ := h.DecodeWithError(data)
|
|
|
+ return e[0]
|
|
|
+}
|
|
