生成后的CGI下载图像 [英] CGI download image after generating

问题描述

我有一个小的python cgi脚本，它接受用户上传的图像，转换成其他格式，然后将新文件保存在临时位置。然后，我希望它自动提示用户下载转换后的文件。我尝试过：

I have a small python cgi script that accepts an image upload from the user, converts in into a different format, and saves the new file in a temp location. I would like it to then automatically prompt the user to download the converted file. I have tried:

# image conversion stuff....
print "Content-Type: image/eps\n" #have also tried application/postscript, and application/eps
print "Content-Disposition: attachment; filename=%s\n" % new_filename #have tried with and without this...
print open(converted_file_fullpath).read()
print

我也尝试过： / p>

I have also tried:

print "Location: /path/to/tmp/location/%s" % new_filename
print

我的浏览器下载 script.cgi 或 script.cgi.ps 。感谢您的帮助。

My browser either downloads script.cgi or script.cgi.ps. Any help is appreciated.

推荐答案

我不确定，但是您是否尝试过用换行符将实际数据与标头分开？编辑：编写 print \n 输出两个换行符，所以我认为应该这样写：

I'm not sure, but have you tried separating actual data from headers by newline? writing print "\n" outputs two newlines, so I think it should be written like that:

print "Content-Type: image/eps"
print "Content-Disposition: attachment; filename=%s" % new_filename
print
print open(converted_file_fullpath).read()

假定 new_filename 具有合理的价值，我看不到这里出了什么问题。

Assuming that new_filename has some reasonable value I can't see what is wrong here.
