觀察HTTP response status code(HTTP回應狀態代碼)
瀏覽網頁時,可以觀察該網頁或網頁內元件(例如嵌入圖檔或聲音)的HTTP response status code(HTTP回應狀態代碼)[1],例如404代表沒有該檔案。
- Mozilla Firefox Firefox 內建的工具 -> 網頁開發者 -> 網頁主控台。快速鍵: Ctrl+Shift+k。
- filter: available
- example as follows:
[23:14:47.836] GET https://www.google.com/ [HTTP/1.1 200 OK 10763ms] [23:14:59.707] GET https://www.google.com/ig/cp/get?hl=zh-TW&gl=&authuser=0&bundleJs=0 [HTTP/1.1 304 Not Modified 1593ms]
- Firebug for Firefox : 切換到「網路」標籤。快速鍵: F12
- Google Chrome 內建的工具 -> 開發人員工具 -> 切換到「network」標籤。快速鍵: Ctrl+Shift+i
- Live HTTP Headers for Firefox
- curl on Linux or Mac e.g. curl -v -o /dev/null https://www.slideshare.net [2]

無法網路連線
- ping local IP
- ping Gateway
- check DNS...
- (optional) ping the IP of external website (有些機器會關閉ICMP ECHO,讓我們無法Ping到它)
distinguish which section met trouble
無法連線到網路的測試步驟
- 檢查網站服務 for Linux
- /etc/init.d/httpd status
- /etc/init.d/mysqld status
- 檢查本機端網站網頁是否能讀取
- lynx 127.0.0.1
- 檢查網站伺服器log
- 從瀏覽器直接瀏覽網站網址
- 透過命令列模擬瀏覽器瀏覽網站 e.g. curl -v -o /dev/null https://www.slideshare.net
網路連線發生不穩
如何看出哪一段線路慢了?
- Windows: 開始 -> 執行 -> 輸入cmd (進入"命令提示字元")
- (會顯示C:\某資料夾>)
- 請在閃爍游標處輸入 tracert web.domain.com (web.domain.com 改成想檢查的網站網址)
- 就可以看出是哪一段慢了,大家先作這個動作會有助於解決問題及增加回覆的速度喔
或者
- 請在閃爍游標處輸入 tracert web.domain.com > c:\result.txt
- 當出現第二次C:\某資料夾> (如果網路連線不穩定, 會花費相當多時間)
- 代表已經將連線過程紀錄成功在 c:\result.txt
- 請將這個文字檔寄給合適的網路管理員
參考資料
- 如何使用 TRACERT 疑難排解 Windows 中的 TCP/IP 問題(使用ICMP協定, 可能因為對方伺服器關閉ICMP回應, 而影響測試結果)
