[英]Python - Calling popen with many arguments
I'm attempting to call popen with a list of arguments. 我试图用参数列表调用popen。
execString = "java -jar {} {} {} {} {} {}".format(os.path.join(config.java_root,
config.java_jar),
self.canvasSize,
self.flightId,
self.domain,
self.defPath,
self.harPath)
execStringList = execString.split()
print execStringList
subprocess.Popen([execStringList])
execStringList is: execStringList是:
['java', '-jar', '/Users/me/Projects/reporting-test/build/clickunit-0.1.jar', '300x1050', '123', 'dev.me.net', '/Users/me/Projects/reporting-test/src/definitions/300x1050.yml', '/Users/me/Projects/reporting-test/out/01/15112']
Which according to: Python OSError: [Errno 2] is the correct format. 其中根据: Python OSError:[Errno 2]是正确的格式。 However, I get the following error: 但是,出现以下错误:
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/subprocess.py", line 672, in __init__
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/subprocess.py", line 1202, in _execute_child
AttributeError: 'list' object has no attribute 'rfind'
If I treat the execString as a string, I get a different error: 如果我将execString作为字符串处理,则会收到另一个错误:
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/subprocess.py", line 672, in __init__
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/subprocess.py", line 1202, in _execute_child
OSError: [Errno 2] No such file or directory
Even though if I run this command from terminal, it works. 即使我从终端运行此命令,它也可以工作。
$> java -jar /Users/me/Projects/reporting-test/build/clickunit-0.1.jar 300x1050 123 dev.me.net /Users/me/Projects/reporting-test/src/definitions/300x1050.yml /Users/me/Projects/reporting-test/out/01/3727
TIA for the help! TIA的帮助!

NEVERMIND, I see the issue. 没关系,我看到了问题。 []...thanks! []...谢谢! heheh 呵呵
execStringList
is already a list, so you can pass it directly to subprocess.Popen
. execStringList
已经是一个列表,因此您可以将其直接传递给subprocess.Popen
。
execString = "java -jar {} {} {} {} {} {}".format(os.path.join(config.java_root,
config.java_jar),
self.canvasSize,
self.flightId,
self.domain,
self.defPath,
self.harPath)
execStringList = execString.split()
print execStringList
# Pass execStringList directly to Popen
subprocess.Popen(execStringList)
