前言
--

本篇的錯誤發生於 [cloudflare](https://www.cloudflare.com/) 設置 [DDoS Protection](https://www.cloudflare.com/en-au/ddos-de/) 機制後發生

在 cloudflare 經過此機制後會向 server 發送 POST 事件

由於 nginx 預設禁止靜態資源配置 POST 請求

因此發生禁止的 Response

設置
--

將 nginx 設置關於 [error\_page](http://nginx.org/en/docs/beginners_guide.html) 的捕捉

\[ default.conf \]

```code
server {

    listen 80;
    listen [::]:80;

    return 301 https://$host$request_uri;
}

server {

    # ...

    error_page 405 =200 https://$host$request_uri;
}
```
