我創建了一個WINDWOS服務利用下面的代碼窗口服務運行時:的Python腳本可以從命令行運行時,但沒有從
import win32service
import win32serviceutil
import win32api
import win32con
import win32event
import win32evtlogutil
import os, sys, string, time
class aservice(win32serviceutil.ServiceFramework):
_svc_name_ = "PAStoDistillerIFC"
_svc_display_name_ = "PAS DW to Distiller Interface"
_svc_description_ = "Service that checks the Clinical Research folder for any new files from PAS to process in Distiller"
def __init__(self, args):
win32serviceutil.ServiceFramework.__init__(self, args)
self.hWaitStop = win32event.CreateEvent(None, 0, 0, None)
def SvcStop(self):
self.ReportServiceStatus(win32service.SERVICE_STOP_PENDING)
win32event.SetEvent(self.hWaitStop)
def SvcDoRun(self):
import servicemanager
servicemanager.LogMsg(servicemanager.EVENTLOG_INFORMATION_TYPE,servicemanager.PYS_SERVICE_STARTED,(self._svc_name_, ''))
#self.timeout = 640000 #640 seconds/10 minutes (value is in milliseconds)
self.timeout = 120000 #120 seconds/2 minutes
# This is how long the service will wait to run/refresh itself (see script below)
while 1:
# Wait for service stop signal, if timeout, loop again
rc = win32event.WaitForSingleObject(self.hWaitStop, self.timeout)
# Check to see if self.hWaitStop happened
if rc == win32event.WAIT_OBJECT_0:
# Stop signal encountered
servicemanager.LogInfoMsg("PAStoDistillerIFC - STOPPED!") #For Event Log
break
else:
#[actual service code between rests]
try:
file_path = "D:\\SCRIPTS\\script.py"
execfile(file_path) #Execute the script
except:
servicemanager.LogInfoMsg("File CRASHED")
pass
#[actual service code between rests]
def ctrlHandler(ctrlType):
return True
if __name__ == '__main__':
win32api.SetConsoleCtrlHandler(ctrlHandler, True)
win32serviceutil.HandleCommandLine(aservice)
要運行此腳本:
import os, re, urllib, urllib2, time, datetime
def postXML(path, fname):
fileresultop = open("D:\\CLinicalResearch\\SCRIPTS\\LOG.txt", 'a') # open result file
fileresultop.write('CheckXXX ')
fileresultop.close()
now = datetime.datetime.now() #####ALWAYS CRASHES HERE######
fileresult = open("D:\\SCRIPTS\\IFCPYTHONLOG.txt", 'a') # open result file
fileresultop = open("D:\\SCRIPTS\\LOG.txt", 'a')
fileresultop.write('Check2 ')
fileresultop.close()
path="D:\\Test2" # Put location of XML files here.
procpath="D:\\Test2Processed" # Location of processed files
now = datetime.datetime.now()
dirList=os.listdir(path)
for fname in dirList: # For each file in directory
if re.search("PatientIndexInsert", fname): # Brand new patient records
fileresultop = open("D:\\SCRIPTS\\LOG.txt", 'a') # open result file
fileresultop.write('Check1 ')
fileresultop.close()
postXML(path, fname)
我有將腳本劃分爲裸碼,我相信這會崩潰。
這從命令行完美工作,我在我自己的登錄下運行Windows服務。 一旦我將datetime函數從函數中取出,它似乎就起作用了。
編輯1:我看到該服務在空白環境中運行。我自己沒有任何環境變量。
編輯2:新增追蹤:
File "D:\ClinicalResearch\SCRIPTS\PAS2DIST.py", line 23, in <module>
postXML(path, fname)
File "D:\ClinicalResearch\SCRIPTS\PAS2DIST.py", line 6, in postXML
now = datetime.datetime.now()
NameError: global name 'datetime' is not defined
你有沒有追溯到墜機事件?您可以使用'traceback'模塊將其作爲字符串獲取,以便在需要時進行記錄。 – 2011-04-12 12:09:14
如果它在日期時間崩潰,我會認爲它必須處理配置文件的區域設置(或作爲服務運行時沒有上述設置)。在C++中會有'CreateProcessAsUser',也許有類似的python函數。 – 2011-04-12 12:13:48
如果您在代碼開始時導入win32traceutil,則可以在安裝時使用win32traceutil.py(C:\ Python27 \ Lib \ site-packages \ win32 \ lib)來監視作爲服務運行時的輸出。這應該讓你看到更好的錯誤。 – 2011-04-12 12:17:33
