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 browser_firefox.png 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 browser_firefox.png : 切換到「網路」標籤。快速鍵: F12
  • Google Chrome Browser chrome.png 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 browser_firefox.png
  • curl on Linux Os linux.png or Mac icon_os_mac.png e.g. curl -v -o /dev/null https://www.slideshare.net [2]

無法網路連線

  1. ping local IP
  2. ping Gateway
  3. check DNS...
  4. (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 Os linux.png
    • /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
