+# user-gray 前端灰度插件
+## 功能说明
+`user-gray`插件实现了前端用户灰度的的功能，通过此插件，不但可以用于业务`A/B实验`，同时通过`可灰度`配合`可监控`,`可回滚`策略保证系统发布运维的稳定性。

+## 配置示例
+### 基础配置
+```yml
+uid-key: userid
+rules:
+- name: inner-user
+  uid-value:
+  - '00000001'
+  - '00000005'
+- name: beta-user
+  uid-value:
+  - '00000002'
+  - '00000003'
+  gray-tag-key: level
+  gray-tag-value:
+  - level3
+  - level5
+deploy:
+  base:
+    version: base
+  gray:
+  - name: beta-user
+    version: gray
+    enable: true
+```
+
+
+cookie中的用户唯一标识为 `userid`，当前灰度规则配置了`beta-user`的规则。
+
+当满足下面调试的时候，会使用`versin: gray`版本
+- cookie中`userid`等于`00000002`或者`00000003`
+- cookie中`level`等于`level3`或者`level5`的用户
+
+否则使用`versin: base`版本
+
+### 用户信息存在JSON中
+
+```yml
+uid-key: appInfo
+uid-sub-key: userId
+rules:
+- name: inner-user
+  uid-value:
+  - '00000001'
+  - '00000005'
+- name: beta-user
+  uid-value:
+  - '00000002'
+  - '00000003'
+  gray-tag-key: level
+  gray-tag-value:
+  - level3
+  - level5
+deploy:
+  base:
+    version: base
+  gray:
+  - name: beta-user
+    version: gray
+    enable: true
+```
+
+cookie存在`appInfo`的JSON数据，其中包含`userId`字段为当前的唯一标识
+当前灰度规则配置了`beta-user`的规则。
+当满足下面调试的时候，会使用`versin: gray`版本
+- cookie中`userid`等于`00000002`或者`00000003`
+- cookie中`level`等于`level3`或者`level5`的用户
+
+否则使用`versin: base`版本
