我有以下代码:
import subprocess
convertargs = ['convert', 'image1.tif', 'img2.tif', 'pdf:-']
print "Content-type: application/pdf\r\n\r\n"
pdf = subprocess.Popen(convertargs, stdout=subprocess.PIPE)
pdf, error = pdf.communicate()
print pdf
它应该采用convertargs,使用imagemagick转换将图像转换为PDF格式。
我知道这有效,因为当我在shell上运行以下内容时:
./pdf.py > test.pdf
它为我创建了一个带有正确图像的整洁小PDF。但是,当我访问www.myhost.com/pdf.py时,它不起作用。我无法弄清楚原因。 这是我的apache错误日志所说的内容:
Traceback (most recent call last):: /Library/WebServer/Documents/pdf.py
File "/Library/WebServer/Documents/pdf.py", line 59, in <module>: /Library/WebServer/Documents/pdf.py

答案 0 :(得分:2)
subprocess.Popen
无法找到convert
,可能是因为网络服务器使用了不同的$ PATH。尝试将其提供给convert
的完整路径,而不仅仅是convert
。
