Question

如果我尝试通过win32service.OpenService（）（以管理员身份运行）控制甚至打开一些服务，我得到＆＃34; pywintypes.error：（5，＆＃39; OpenService＆＃39;，＆＃39;访问被拒绝。＆＃39;）＆＃34;。但是，从服务控制台控制相同的服务是成功的。这是为什么？以下是复制问题的示例代码：

import win32service as ws


def get_handle(service_name):
    # service_name is the internal service name, not the display name.
    hSCManager = ws.OpenSCManager(None, None, ws.SC_MANAGER_ALL_ACCESS)
    return ws.OpenService(hSCManager, service_name, ws.SERVICE_ALL_ACCESS)


sh = get_handle("CertPropSvc")  # Certificate Propagation, same problem with
                                # BitLocker Drive Encryption Service (BDESVC)

Answer 1

通过在打开SCM和服务时请求较低权限来解决问题：

import win32service as ws


def get_handle(service_name):
    # service_name is the internal service name, not the display name.
    # SC_MANAGER_CONNECT is enough.
    hSCManager = ws.OpenSCManager(None, None, ws.SC_MANAGER_CONNECT)
    # SERVICE_CHANGE_CONFIG is enough.
    return ws.OpenService(hSCManager, service_name, ws.SERVICE_CHANGE_CONFIG)


sh = get_handle("CertPropSvc")  # Certificate Propagation, BitLocker Drive
                                # Encryption Service (BDESVC) can also be used.

Python - 使用win32service打开服务即使以管理员身份返回Access Denied
