有用 - 通过Cloudflare API进行CDN刷新

# 通过Cloudflare API进行CDN刷新

## 1.Cloudflare CDN刷新说明

　　1.Cloudfalre同Akamai一样，只有刷新，没有预热的概念。

　　2.通过Cloudflare API进行刷新，需要用到登录用户的\[邮箱\]\[api密钥\]\[区域ID\]。

## 2.获取API授权

## 2.1 获取API密钥X-Auth-Key

　　注：Cloudfalre的API密钥是每个账户有自己的API密钥。

## 3.通过API进行刷新

**示例**

### Cloudflare CDN相关api的文档

-   [https://api.cloudflare.com/#getting-started-requests](https://api.cloudflare.com/#getting-started-requests)
-   [https://api.cloudflare.com/#zone-purge-all-files](https://api.cloudflare.com/#zone-purge-all-files)

-   [https://api.cloudflare.com/#zone-purge-files-by-url](https://api.cloudflare.com/#zone-purge-files-by-url)

-   [https://api.cloudflare.com/#zone-purge-files-by-cache-tags,-host-or-prefix](https://api.cloudflare.com/#zone-purge-files-by-cache-tags,-host-or-prefix)  


### 调用API针对文件刷新

```bash
curl -X POST "https://api.cloudflare.com/client/v4/zones/2869xxxxxxxxxxxxe1c3(区域ID)/purge_cache" \
-H "X-Auth-Email: xx@xx.jp" -H "X-Auth-Key: f2cdcdb9xxxxxxxxxx7f1072(API密钥)" \
-H "Content-Type: application/json" \
--data '{"files":["https://www.baidu.com/HotfixAssets/Global_CBT/1.5.2076/Android/2/hot_depend_tex_lightmap-0_comp_light.ab"]}' 
```

### 调用API针对目录刷新

```bash
curl -X POST "https://api.cloudflare.com/client/v4/zones/2869xxxxxxxxxxxxxxe1c3(区域ID)/purge_cache" \
-H "X-Auth-Email: xx@xx.jp" \
-H "X-Auth-Key: f2cdcdb9xxxxxxxxxxxxxxx97f1072(API密钥)" \
-H "Content-Type: application/json" \
--data '{"prefixes":["www.baidu.com/HotfixAssets/Global_OBT/6.3.6000/Android/3/"]}'
```

### 预热，执行预热后会在全球一级节点进行预热

```bash
#!/bin/bash
curl -I http://www.example.com/1.txt >> log.txt
```

也可以这样：

url放在一个文件 `file.txt`:

```bash
url="http://www.google.de"
url="http://www.yahoo.de"
url="http://www.bing.de"
```

 然后做

```bash
curl -K file.txt -svo /dev/null
```

## 4.通过API刷新CDN频率限制

Rate limiting:The Cloudflare API sets a maximum of 1,200 requests in a five minute period.

**5分钟1200次**
