Python Server Pages - Fruit Suggest

Python Server Pages - Fruit Suggest


今天處理了一台伺服器~ 整個給它重灌Debian 4.0r4~ 因為這台伺服器先前被SSH-Attack~ 所以連IP都被封鎖住~

所以千萬別認為裝了「SSH」就絕對安全~ 因為總是有「無聊」的人會利用工具來做「暴力字典攻擊法」想辦法入侵... 所以防火牆的設定是不可少的~ 真搞不懂為什麼有人那麼「無聊」..= ="(我時間都不夠用了~)

好了~ 這不是重點~ 這篇的重點在於測試一個「Python Web Application」~ 我給它的主題就叫做「Fruit Suggest」~ 從名稱來看就知道和「Google Suggest」脫離不了關係~

是的~ 這個範例會結合「Python Server Pages」、「SQLite3」、「YUI Ajax」、「Google Suggest」和「PSP Template」,並且在「Debian Linux」的環境下執行~

我想~ 用一個最實際的簡單案例就是最好的驗證!!

不過~ 一開始還遇到許多問題~ 由於「Debian 4.0r4」預設是安裝「Python 2.4.4」版本~ 但是~ 我想用最新的「Python2.5」來執行這樣的環境~ 畢竟它有整合了「SQLite」~

所以要處理解決「Python2.5」的環境~ 筆者採用自行編譯「mod_python」的方式來處理~ 所以捨棄apt安裝「libapache2-mod-python」的方式~

如果你也需要這樣的解決方案~ 請參考「Jason R Briggs · mod_python and python2.5」的說明~

<%
for f in search:
%>
<%=f[0]%>

data.dat (sqlite)

Fruit table的結構如下:

create table fruit(
	id int,
	name varchar
)

insert into fruit values (1,'apple')

    哈哈~ 就是你~ 抓包!!
    雖然我以前也做過那樣的事~ XDDD
