## server\_name

server\_name對應到網域名稱。

## try\_file

有關try\_file，他會找目錄下的文件，有時寫了 location ，但路由總是只有\可以執行，可以看看是不是try\_file沒有刪掉，因為他會優先執行然後沒找到就回傳404，另外可能不經意把自己的源碼給露出了

ex:

```
try_files $uri $uri/ =404;
```

## Underscore header

有時我們幫header取名時有\_，ex: access\_\_token這時會被nginx預設擋下，我們需加上

```
underscores_in_headers on;
```
