Question

我希望在文件上传到webdav服务器时获取文件传输进度信息。我尝试将WithEvents用于Session对象的set处理程序，但它会因错误而停止：

C:\Miniconda3\python.exe E:/backup_1c/winscp.py
Traceback (most recent call last):
  File "E:/backup_1c/winscp.py", line 16, in <module>
    wcpSession.open(winscp_session_option)
  File "<COMObject WinSCP.Session>", line 2, in open
pywintypes.com_error: (-2147352567, 'Error.', (0, 'mscorlib', 'Member group not found. (Exception HRESULT: 0x80020003 (DISP_E_MEMBERNOTFOUND))', None, 0, -2147352573), None)

Process finished with exit code 1

脚本代码是：

# -*- coding: utf-8
import win32com.client as win32

class WinScp_ISessionEvents:
    def OnFileTransferProgress(self, e):
        print(e.FileProgress)

if __name__ == "__main__":
    wcpSession = win32.dynamic.Dispatch('WinSCP.Session')
    winscp_session_option = win32.dynamic.Dispatch('WinSCP.SessionOptions')
    winscp_session_option.Protocol = 3
    winscp_session_option.HostName = "webdav.yandex.ru/"
    winscp_session_option.UserName = "user"
    winscp_session_option.Password = "password"
    win32.WithEvents(wcpSession, WinScp_ISessionEvents)
    wcpSession.open(winscp_session_option)
    wcpSession.PutFiles('E:\Exchange\File.xls', '/File.xls')

根据错误消息我在WinScp_ISessionEvents类中有错误的函数名称，我尝试了不同的名称，如FileTransferProgress，Session_FileTransferProgress，wcpSession_FileTransferProgress，wcpSession_OnFileTransferProgress等等。

Answer 1

callstack在wcpSession.open显示问题，而不是win32.WithEvents。

问题不在于.Open，而不是.open？

使用pywin32通过COM接口的WinSCP会话事件处理程序
