权限管理服务平台

该服务采用比较流行的微服务思想, 利用shiro<域，动作，实体>思想，实现权限管理平台服务， 它支持单用户多角色 , 比RBAC的资源管理更细粒度化

权限管理服务平台的实现，主要由三个步骤构成：

• 第一步：判断URL是否在白名单中，如果是，直接返回状态码：200
• 第二步：解析URL，获取功能ID和实体ID，服务初始化阶段，会构建多叉树
• 第三步：获取<域，动作，实体>, 并在redis中采用SET集合存储<UserId-FuncId, SET集合={实体1, 实体2, ... , 实体N}>

权限管理库表设计

环境依赖

• beego框架
• redis

OpenResty配置

权限管理安插在Nginx Access访问阶段，对http请求的合法性进行校验

access_by_lua_file "/data/openresty/lua_files/test_ycfm_lua_files/access_by_grbac.lua"

-- GRBAC权限管理模块
ngx.req.read_body()
local bodyData = ngx.req.get_body_data()
ngx.log(ngx.ERR, "body data:", bodyData)
local cjson = require "cjson"
local info={
        ["body"] =  bodyData,
        ["method"] = ngx.req.get_method(),
        ["uri"] = ngx.var.uri,
}
local encode = cjson.encode(info)
local res = ngx.location.capture('/v1/grbac/functions/tree_parsing', {method=ngx.HTTP_POST, body=encode})
if res.status == 403 then
        ngx.exit(ngx.HTTP_FORBIDDEN)
end
--- 这里需要注意的地方：
--- 当http请求头Content-type: multipart/form-data时，由于子请求继承父请求的信息，导致body无法改变
--- 需要在nginx中location ~ /v1/grbac体中增加下面一句：
——- `proxy_set_header   Content-Type   "application/x-www-form-urlencoded"`;
--- 这样做body=encode才能生效

DEMO

解析树性能测试结果

测试数据：

functions表： 共259条
role_function_relationships表：1036条
roles表： 7条
user_roles表: 31条
white_list表: 85条

可以看到一个请求耗时平均: 0.108ms

ab结果中指标说明，可参考ab test

ab -c 8000 -n 800000 -p post.txt -H "Accept: application/json"  -H "XXXX-XXXX-XXX-Id: 12" -H "XXXX-XXXX-XXXX-Id: 3"  http://120.**.**.193:30100/v1/grbacs/functions/tree_parsing
