Building software system II !!: Test 02

test 02 directory list by cgi

จากคราวที่แล้วที่ได้ทดสอบ ให้ python เขียน html ดู คราวนี้จึงได้ทดสอบการใช้

cgi ในการเขียนหน้าเว็บ โดย python

ขั้นแรก จัดเตรียม เซิฟเวอร์ให้พร้อมที่จะรัน cgi

ทดสอบรันโค้ดที่ได้เขียนมา

โดยเข้าไปที่ 0.0.0.0:8000/#dir/#file โดย #dir คือ directory ที่อยู่ภายใน server และ #file คือชื่อของ file
