如何通过Python代码登录SAP时检查错误

Posted 2021-04-12

我尝试通过Python登录SAP，但在运行代码后，我收到以下错误

connection = application.OpenConnection("A101.TA2", True) File "<COMObject <unknown>>", line 3, in OpenConnection pywintypes.com_error: (-2147352567, 'Exception occurred.', (1000, 'saplogon', 'SAP Logon connection entry not found', None, 0, 0), None)

登录界面就像这个http://img1.imagehousing.com/0/sap-370961.png

我尝试了A101，A101.TA2 A101.TA2 PRD / ERi TEN作为连接名称，都失败了。什么是正确的连接名称？

import win32com.client
import sys
import subprocess
import time

def saplogin():



  path = r"C:Program Files (x86)SAPFrontEndSAPguisaplogon.exe"
  subprocess.Popen(path)
  time.sleep(3)

  SapGuiAuto = win32com.client.GetObject('SAPGUI')
  if not type(SapGuiAuto) == win32com.client.CDispatch:
      return

  application = SapGuiAuto.GetScriptingEngine

  if not type(application) == win32com.client.CDispatch:

      SapGuiAuto = None
      return

  connection = application.OpenConnection("A101.TA2", True)
  print('5')
  if not type(connection) == win32com.client.CDispatch:
      application = None
      SapGuiAuto = None
      return

  session = connection.Children(0)
  if not type(session) == win32com.client.CDispatch:
      connection = None
      application = None
      SapGuiAuto = None
      return

  session.findById("wnd[0]/usr/txtRSYST-BNAME").text = "USERNAME"
  session.findById("wnd[0]/usr/pwdRSYST-BCODE").text = "PASSWORD"
  session.findById("wnd[0]").sendVKey(0)




saplogin()

答案

我不使用Python，但我会在连接字符串中使用全名。

例如：

connection = application.OpenConnection("A101.TA2 PRD / Eri TEN", True)

此致，ScriptMan
