Question

我想從powershell調用帶參數的wlst/jython腳本。 （下面是一個簡化的版本）

hello.ps1

param (
    [string]$cmd = "none" 
) 

echo "cmd - $cmd" 
Switch ($cmd) { 
    "hello" { 
      Write-Host "Start hello ..." 
      $script='C:\_WORK_\hello.py' 
      & java -cp C:\bea\tpc\WEBLOG~1\server\lib\weblogic.jar weblogic.WLST $script 
     } 
    "main" { 
      Write-Host "w main $cmd" 
      $cmd='-c "hello"' 
      $script="C:\_WORK_\hello_main.py" 
      Write-Host "script: $script" 
      & java -cp C:\bea\tpc\WEBLOG~1\server\lib\weblogic.jar weblogic.WLST $script $cmd 
    } 
    Default {Write-Warning "Invalid Choice. Try again." 
        sleep -milliseconds 750} 
    } #switch 

hello.py

print "Hello without main/args" 

hello_main.py

import getopt 

def main(): 
    try: 
     opts, args = getopt.getopt(sys.argv[1:], "hc:v", ["help", "command="]) 
    except getopt.GetoptError, err: 
     # print help information and exit: 
     print str(err) # will print something like "option -a not recognized" 
     usage() 
     sys.exit(2) 
    command = None 
    verbose = False 
    for o, a in opts: 
     if o == "-v": 
      verbose = True 
     elif o in ("-h", "--help"): 
      usage() 
      sys.exit() 
     elif o in ("-c", "--command"): 
      command = a 
     else: 
      assert False, "unhandled option" 
    print 'command: '+command 
    if (command == 'hello'): 
     print "if hello" 

if __name__ == 'main': 
    main() 

隨着「hello.ps1 -cmd主「劇本在」打印「命令後終止：'+ command' 我不明白爲什麼

>powershell c:\_WORK_\SAS\hello.ps1 -cmd main 
cmd - main 
w main main 
script: C:\_WORK_\SAS\hello_main.py

Answer 1

"main" { 
     Write-Host "w main $cmd" 
      $arg0 = "C:\_WORK_\SAS\hello_main.py" 
      $arg1 = "-c" 
      $arg2 = "hello" 

      $allArgs = @($arg0, $arg1, $arg2) 

     & java -cp C:\bea\tpc\WEBLOG~1\server\lib\weblogic.jar weblogic.WLST $allArgs
