我正在尝试从我的 python (2.75) 脚本中调用 wget：

cmd = ['wget', 'https://192.168.0.1/003/', '--tries=5', '--http-user=foo', '--http-passwd=bar', '--auth-no-challenge', '--no-check-certificate', '--output-document=temp/page.html']
proc = subprocess.Popen(cmd)
# same with subprocess.call(cmd)

它在 IDE (eclipse) 和终端中也可以正常工作，但是当我尝试从 Gnome Schedule User Guide V2.2 运行它时，我得到以下信息：

--2013-08-16 11:27:35--  https://192.168.0.1/003/
Connecting to 192.168.0.1:443... connected.

...所以不是采用命令“wget arg1 arg2 arg3 ...”，而是尝试运行：“wget arg1”“wget arg2”“wget arg3”...

从调度程序运行时可能产生不同结果的任何线索？

我在调度程序中使用的命令是：“python /home/python/Download/Download.py”

谢谢

我自己解决了这个问题，将第二个参数移到最后一个位置：

cmd = ['wget', '--tries=5', '--http-user=foo', '--http-passwd=bar', '--auth-no-challenge', '--no-check-certificate', '--output-document=temp/page.html', 'https://192.168.0.1/003/']

它现在可以工作，但我仍然想知道为什么在终端或 IDE 中它工作正常，而不是从调度程序运行时......
