子进程和硬编码目录工作正常,变量失败
所以我遇到了一个问题,现在确定我做错了什么。我正在使用 python 2.4 和 subprocess 模块。这与我的 django 网站集成。我有一个要求一些用户输入的表单,它将其放入一个文件中,然后使用文件所在的目录启动脚本。
如果我对字符串中的目录进行硬编码,它将正常工作,并输出 wlst脚本,如果我不这样做,它将无法工作,只是连接并认为它已完成。
仍然没有任何信息。说说为什么。该脚本可以在正常的命令行中正常工作,甚至可以在正常的 python 代码中正常工作。我唯一能说的就是变量。
代码:
if form.is_valid():
env = form.cleaned_data['env']
user = form.cleaned_data['user']
group = form.cleaned_data['group']
role = form.cleaned_data['role']
id = ''.join(random.choice(string.ascii_uppercase + string.digits) for x in range(6))
root = "/opt/tools/Mapper/output/webui/%s" % (id)
if not os.path.exists(root):
os.makedirs(root)
output = open(root+"/mapping.out", 'w')
if (user):
user_stg = "User:"+user+":"
password = User.objects.filter(user__contains=user).values('password')
password_f = open(root+"/passwords.out", 'w')
password_out = "%s:%s" % (user, password[0]['password'].encode('ascii'))
password_f.write(password_out)
if (group):
grp_stg = "GroupName:"+group+":"
if(role):
role_stg = "RoleName:"+role
out_stg = user_stg+grp_stg+role_stg
output.write(out_stg+"\n")
command = "/opt/tools/Mapper/bin/wlst /opt/tools/Mapper/bin/creator -e ldap.dev -s pacdcespopsa1:7001 -o /opt/tools/Mapper/output/webui/JBHSMN"
args = shlex.split(command)
print args
resp = HttpResponse(command_output(args));
def command_output(args):
import subprocess
return subprocess.Popen(args, stdout=subprocess.PIPE, stderr=subprocess.PIPE).communicate()[0]
此代码与变量驱动代码之间的唯一区别是我有 for
command = "/opt/tools/Mapper/bin/wlst /opt/tools/Mapper/bin/creator -e ldap.dev -s pacdcespopsa1:7001 -o %s" % (root)
So am running into an issue and now sure what I am doing wrong. I am using python 2.4 and the subprocess module. This is integrated with my django site. I have a form that askes for some user input, it puts that into a file then starts the script with the directory the file(s) are in.
If I hardcode the directory in the string it will work fine, and out put the wlst script, if I do not it will not work and just connected and think that it is done.
Still stuck with no information. Onto why. The script works fine normal command line, and even from normal python code. The only thing I could tell is with the variables.
Code:
if form.is_valid():
env = form.cleaned_data['env']
user = form.cleaned_data['user']
group = form.cleaned_data['group']
role = form.cleaned_data['role']
id = ''.join(random.choice(string.ascii_uppercase + string.digits) for x in range(6))
root = "/opt/tools/Mapper/output/webui/%s" % (id)
if not os.path.exists(root):
os.makedirs(root)
output = open(root+"/mapping.out", 'w')
if (user):
user_stg = "User:"+user+":"
password = User.objects.filter(user__contains=user).values('password')
password_f = open(root+"/passwords.out", 'w')
password_out = "%s:%s" % (user, password[0]['password'].encode('ascii'))
password_f.write(password_out)
if (group):
grp_stg = "GroupName:"+group+":"
if(role):
role_stg = "RoleName:"+role
out_stg = user_stg+grp_stg+role_stg
output.write(out_stg+"\n")
command = "/opt/tools/Mapper/bin/wlst /opt/tools/Mapper/bin/creator -e ldap.dev -s pacdcespopsa1:7001 -o /opt/tools/Mapper/output/webui/JBHSMN"
args = shlex.split(command)
print args
resp = HttpResponse(command_output(args));
def command_output(args):
import subprocess
return subprocess.Popen(args, stdout=subprocess.PIPE, stderr=subprocess.PIPE).communicate()[0]
The only difference between this code and the varable driven one is that I have for
command = "/opt/tools/Mapper/bin/wlst /opt/tools/Mapper/bin/creator -e ldap.dev -s pacdcespopsa1:7001 -o %s" % (root)
