【问题描述】：
我一直很难同时导入图像和 CGI。所以，基本上我想上传一个 gif 图像，然后显示输出，它是图像的缩略图。我收到一堆错误。我无法同时使用 from PIL import Pillow 和 cgi。这是下面的代码。非常感谢您的帮助。我进行了数小时的研究，但无法弄清楚。我收到此错误：标题前脚本输出结束：save_file.py
#!C:\Anaconda3\python.exe
from PIL import Image
import cgi, os
import cgitb; cgitb.enable() #cgitb enabled for bug tracking purposes
try: # Windows needs stdio set for binary mode.
import msvcrt
msvcrt.setmode (0, os.O_BINARY) # stdin = 0
msvcrt.setmode (1, os.O_BINARY) # stdout = 1
except ImportError:
pass
form = cgi.FieldStorage()
# A nested FieldStorage instance holds the file
fileitem = form['file']
# Test if the file was uploaded
if fileitem.filename:
# strip leading path from file name to avoid directory traversal attacks
fn = os.path.basename(fileitem.filename)
ext = fn[-3:]
condi = 'gif'
if ext == condi:
open('tmpmedia/' + fn, 'wb').write(fileitem.file.read())
message = 'The file "' + fn + '" was uploaded successfully'
selectfunction = "Please select a function from below"
else:
message = 'You can only upload a gif image. No file was uploaded'
size = (128,128)
saved = "thumb.jpg"
infile = ('C:\\xampp\\htdocs\\aztec\\tmpmedia\\gif' + fn)
try:
im = Image.open(infile)
except:
print("Unable to load image")
im.thumbnail(size)
im.save(saved)
print ("Content-Type: text/html\n")
print ("<html>")
print("<body>")
print(message)
print("</body>")
print("</html>")

请edit 提出您的问题，并附上您收到的任何错误或追溯的全文。

我建议将 print ("Content-Type: text/html\n") 放在最顶部；不确定您要托管什么，但至少 apache 对首先看到它非常挑剔。 （此外，您是否在 Windows 上的 /var/log/httpd/error.log 等效项中看到任何内容）。最后...仅最后 6 行将消息设置为 hello world（以排除枕头问题）
