# DuEdge Recipes
[duedge](https://duedge.baidu.com/) 为租户提供 FaaS(Serverless) 服务, 租户可以将功能函数运行在 Edge 端 (cdn 节点), 实现边缘计算应用场景.
核心功能:
- 可根据业务应用直接编写计算函数, 无需考虑服务器等基础资源的配置, 按实际计算量计费;
- 遍布全国各地的超级计算中心, 支持各种网络线路的高速稳定连接, 为函数计算提供基础支持;
- 自动为函数分配计算资源, 并根据网络连接情况为服务分配最优路径的边缘节点;
此代码仓库旨在提供常见任务的示例, 包括:
- About Log (如何记录 log)
- About Cache (cache 相关操作)
- fetch (利用 fetch 回源)
- cache (操作本地缓存)
- About KV
- global (全局只读 KV)
- string (机房内可读可写 KV, string 相关, get/set/setnx/incrby)
- bit (机房内可读可写 KV, bit 相关, getbit/setbit/bitcount)
- list (机房内可读可写 KV, list 相关, lpush/rpush/lpop/rpop/lrange/ltrim)
- A/B Testing (根据 cookie 修改 uri 为 A/B 两种页面)
- Redirecting Unauthenticated Users to a Sign-In Page (根据 cookie 情况重定向到登录页)
- Aggregating Multiple Requests (合并多分请求结果)
- Conditional Routing
- Device Type (不同设备类型, 访问不同页面)
- Custom Headers (使用特殊 header 替换 uri)
- Custom responses that don’t hit origin servers
- Ignore POST And PUT HTTP Requests (忽略 POST/PUT 请求)
- Deny A Spider Or Crawler (拦截爬虫)
- Prevent A Specific IP From Connecting (根据 clinetIP 拦截)
- Hot-link Protection (防盗链)
- About Post Requests
- Read Post Data (获取 POST body)
- Create a Post Request (构造 POST 请求)
- Random Content Cookies (构造 cookie)
- Signed Requests
- Generating Signed Requests (生成签名)
- Verifying Signed Requests (验证签名)
- Normalizing Query String Parameters to Improve the Cache Hit Ratio (参数排序, 提高缓存命中率)
- Rewrite request uri and Updating Error Statuses
- Rewrite request uri (改写请求)
- Update the Error Status Code to 302-Found (重定向异常响应)
- About AI
- Call face detect example (调用人脸检测)
- Call image censor example (调用图像审核)
- Call antiporn example (调用色情识别)
- Call terror censor example (调用暴恐识别)
- Call politician censor example (调用政治人物)
- Prevent uploading erotic image (防止上传色情图片)
- Prevent access to erotic image (防止用户访问色情图片)
## 快速开始
在 [duedge](https://duedge.baidu.com) 官网接入域名, 绑定 `Hello World` 函数, 符合 `route` 规则的请求均会返回 200 / Hello DuEdge!
### node
```js
async function f(event) {
return {status: 200, body: 'Hello DuEdge!'};
}
exports.handler = f;
```
### python
```python
async def handler(event):
return {'status': 201, 'body': 'Hello DuEdge!'}
```
### lua
```lua
local _M = {}
function _M.handler(event)
return {status = 200, body = 'Hello DuEdge!'}
end
return _M
```
## 测试
代码编辑页面支持在线测试函数调用, 通过请求触发函数需要域名正式接入 duedge;
