使用ConfigParser讀取字符串作爲配置值

Question

我正在嘗試編寫一個實用程序，讓我可以根據配置文件將命令設置爲在unix shell中運行。從本質上講，我希望能夠給一個[Command List]和預期[Response List]。這裏是我的配置文件中的一個例子：

# Command File 
# List of commands to be carried out for each host listed in `veri.serv.cfg` 

[Command List] 
; T server 
nc -zw1 159.1.1.1 9988 | gawk '{print $7}' 

; P Server 
nc -zw1 sup.serv.com 8050 | gawk '{print $7}' 

; G L Service 
nc -zw1 hi.serv.com 80 | gawk '{print $7}' 

; L and N Hosts 
nc -zw1 l.serv.com 80 | gawk '{print $7}' 
nc -zw1 ln.serv.com 443 | gawk '{print $7}' 
nc -zw1 llnn.serv.com 443 | gawk '{print $7}' 

然而，當我試圖解析使用parser.items('Command List')它，我得到：

File "veri.py", line 22, in <module> 
    print subConfigParser.read(os.path.join(relativeRunPath, 'veri.cfg')) 
    File "/usr/lib/python2.7/ConfigParser.py", line 305, in read 
    self._read(fp, filename) 
    File "/usr/lib/python2.7/ConfigParser.py", line 546, in _read 
    raise e 
ConfigParser.ParsingError: File contains parsing errors 

[line 6]: "nc -zw1 159.1.1.1 9988 | gawk '{print $7}'\n" 
[line 9]: "nc -zw1 sup.serv.com 8050 | gawk '{print $7}'\n" 
[line 12]: "nc -zw1 hi.serv.com 80 | gawk '{print $7}'\n" 
[line 15]: "nc -zw1 l.serv.com 80 | gawk '{print $7}'\n" 
[line 16]: "nc -zw1 ln.serv.com 443 | gawk '{print $7}'\n" 
[line 17]: "nc -zw1 llnn.serv.com 443 | gawk '{print $7}'\n" 

使用SafeConfigParser作爲值時，我不能以完整的字符串讀取嗎？

完整文件：

#! /usr/bin/python25 
import os 
import ConfigParser 

# --- sudo consts --- # 
# relative path, regardless of where we're executing from 
RELATIVE_PATH = os.path.abspath(os.path.dirname(__file__)) 
BASE_SERVER_FILE = os.path.join(RELATIVE_PATH, 'cfg', 'veri.serv.cfg') 
BASE_CONFIG_FILE = os.path.join(RELATIVE_PATH, 'cfg', 'veri.base.cfg') 
# --- end consts --- # 

baseConfigParser = ConfigParser.SafeConfigParser() 
baseConfigParser.read(BASE_CONFIG_FILE) 
runlist = baseConfigParser.get('Config List', 'runlist').strip().split("\n") 
print runlist 

for subDir in runlist: 
    print subDir 
    relativeRunPath = os.path.join(RELATIVE_PATH, subDir) 
    subConfigParser = ConfigParser.SafeConfigParser() 
    subConfigParser.read(os.path.join(relativeRunPath, 'veri.cfg')) 
    print subConfigParser.items('Command List')   ###### <<< Error Here 
    if os.path.isfile(os.path.join(relativeRunPath, 'veri.serv.cfg')): 
     subServSpecified = true 
     subServConfigParser = ConfigParser.SafeConfigParser() 
     subServConfigParser.read(os.path.join(relativeRunPath, 'veri.serv.cfg')) 
     print subServConfigParser.get('Config List', 'runlist')

您的配置文件沒有使用有效的格式ConfigParser。它需要一系列的部分，隨後命名的選項，如

[T server] 
commands = nc -zw1 159.1.1.1 9988 | gawk '{print $7}' 

[P Server] 
commands = nc -zw1 sup.serv.com 8050 | gawk '{print $7}' 

[G L Service] 
commands = nc -zw1 hi.serv.com 80 | gawk '{print $7}' 

[L and N Hosts] 
commands = nc -zw1 l.serv.com 80 | gawk '{print $7}' 
    nc -zw1 ln.serv.com 443 | gawk '{print $7}' 
    nc -zw1 llnn.serv.com 443 | gawk '{print $7}' 

然後，您可以獲取值

>>> from ConfigParser import SafeConfigParser 
>>> parser = SafeConfigParser() 
>>> parser.read('myconfig.ini') 
['myconfig.ini'] 
>>> for section in parser.sections(): 
...  print 'section', section 
...  for option in parser.options(section): 
...    print parser.get(section, option) 
... 
section T server 
nc -zw1 159.1.1.1 9988 | gawk '{print $7}' 
section P Server 
nc -zw1 sup.serv.com 8050 | gawk '{print $7}'                                 
section G L Service                                        
nc -zw1 hi.serv.com 80 | gawk '{print $7}'                                  
section L and N Hosts                                       
nc -zw1 l.serv.com 80 | gawk '{print $7}'                                  
nc -zw1 ln.serv.com 443 | gawk '{print $7}'                                  
nc -zw1 llnn.serv.com 443 | gawk '{print $7}'
