使用nginx處理靜態資源請求，其他交給node

 　　因爲項目後臺使用的是node，然而node不適合對靜態資源的處理，由於他的異步處理（事件輪詢）機制，因此更擅長的是密集I/O型的應用，因此我就有了一個想法，使用nginx來作反向代理，當請求的是靜態資源的時候，直接由nginx（監聽80端口）本身處理並返回，其餘非靜態資源請求轉發至node(8080端口)，由node來處理。下面是個人nginx配置文檔，nginx安裝請自行百度，大把資料啦~

　　配置解釋：當請求是以（css, js, gif, jpg, jpeg, png, bmp, swf)結尾的時候則nginx直接攔截請求（上面源碼中標紅的部分），由nginx靜態服務器直接返回靜態資源，而若是不是的話則將請求轉發到node服務（上面源碼中標藍的部分），由node來完成其他請求。
