我编辑了我的代码以这样的方式工作：
#! /usr/bin/env python
import os
import cgi
import cgitb
cgitb.enable()
import sys
def check_file_extension(display_file):
input_file = display_file
nm,file_extension = os.path.splitext(display_file)
return file_extension
form = cgi.FieldStorage()
type_of_file =''
file_nm = ''
nm =''
path = '/home/shantala/Documents'
not_found = 0
if form.has_key("file1"):
file_nm = form["file1"].value
for f in next(os.walk(path))[2]:
if str(f) == str(file_nm).strip():
not_found = 0
absolute_path_of_file = os.path.join(path, f)
type_of_file = check_file_extension(absolute_path_of_file)
if type_of_file == '.pdf':
file_read = file(absolute_path_of_file,'rb').read()
print 'Content-type: application/pdf\n'
print file_read
if type_of_file == '.txt':
file_read = file(absolute_path_of_file,'rb').read()
print 'Content-type: text/html\n'
print file_read
if type_of_file == '.png':
file_read = file(absolute_path_of_file,'rb').read()
print 'Content-type: image/png\n'
print file_read
if type_of_file == '.pdf':
file_read = file(absolute_path_of_file,'rb').read()
print 'Content-type: application/pdf\n'
print file_read
if type_of_file == '.JPG':
file_read = file(absolute_path_of_file,'rb').read()
print 'Content-type: image/jpg\n'
print file_read
if type_of_file == '.bmp':
file_read = file(absolute_path_of_file,'rb').read()
print 'Content-type: image/bmp\n'
print file_read
break
else:
not_found = 1
if not_found == 1:
pass
