# RedisAB
## 总体设计
1. 数据持久化到redis里面
2. 大量使用redis-lua脚本（基本每一个接口都是使用redis-lua脚本实现，提升性能的同时，能利用redis-lua脚本的原子性达到类似事务的效果）
3. 设计一个测试环境和正式环境，通过"X-Env"识别，数据通过redis db分开存储
4. 通过"X-User-Id"传递user_id
5. 设计一个控制台管理流量层和实验（登录使用http auth_basic）
### murmurhash2
```
local ffi = require "ffi"
ffi.cdef[[
typedef unsigned char u_char;
uint32_t ngx_murmur_hash2(u_char *data, size_t len);
]]
murmurhash2 = function(value)
return tonumber(ffi.C.ngx_murmur_hash2(ffi.cast('uint8_t *', value), #value))
end
```
## 启动项目
```
docker pull lloydzhou/ab
docker run --rm -it -e INTERVAL=60 -e HTPASSWD='abadmin:$apr1$EJ2gyYP1$JirougEJ3sK/nF8aj63Zw1' -v `pwd`/data:/data:rw -p 8011:80 lloydzhou/ab
docker run --rm -it -e INTERVAL=60 -e HTPASSWD="$(docker run --rm -it xmartlabs/htpasswd abadmin abpasswd )" -v `pwd`/data:/data/:rw -p 8011:80 lloydzhou/ab
```
### params
`INTERVAL`: interval for run crontab to calc data
`HTPASSWD`: http base auth for login to admin panel, default is `abadmin/abpasswd`
## 接口
1. 获取变量接口
```
curl "localhost:8011/ab/var?name=var1" -H 'X-Env: dev' -H 'X-User-Id: 0001'
-->
返回当前user_id(0001)在这个实验中分配的变量: 类型是数字，值为2
{"value":"2","msg":"success","layer":"layer1","code":0,"hash":838060847,"test":"test1","type":"number"}
```
2. 回传指标接口
```
上传名字为target1的指标，代表user_id=0001这个用户在当前实验版本下产生转化的指标
curl "localhost:8011/ab/track?name=var1" -H 'X-Env: dev' -H 'X-User-Id: 0001' -d '{"target1": 1}'
-->
{"msg":"success","code":0}
```
## demo
1. 创建一个名字叫layer1的流量层
2. 在这个流量曾创建一个名字叫test1的实验
3. 给这个实验创建两个版本(value=0/1)分别分配50%的流量
4. 给这个实验创建一个叫做target1的指标
