本文介绍了是否有使用 pywin32 createprocessasuser 并获取输出的好例子?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我需要使用 pywin32 方法以不同的用户身份创建进程，然后从生成的进程中获取 stdout、stderr 和错误代码，并在进程运行时将输入输入到进程中.问题是，我似乎无法为 createprocess 函数找到一个很好的例子.由于我需要以不同的用户身份运行子进程，然后获取 stderr、stdout、stdin 中的提要并在完成后检索错误代码，因此这个问题变得更加复杂.
I need to use the pywin32 method of creating a process as a different user and then get the stdout, the stderr and the error code from the spawned process as well as feed input into the process while it is running. The problem is, I can't seem to find a very good example of this for the createprocess function. This problem is further complicated by the fact that I need to run the subprocess as a different user and then get the stderr, stdout, feed in the stdin and retrieve the errorcode when it is done.
推荐答案
这里是 CreateProcess 函数系列的 ctypes 定义.我编写了它们来伴随后续的 create_process 包装函数使用 CREATIONINFO 和 STARTUPINFO 实例来控制如何创建和启动进程，包括使用哪个 API.
Here are the ctypes definitions for the CreateProcess family of functions. I've written them to accompany the subsequent create_process wrapper function that uses CREATIONINFO and STARTUPINFO instances to control how the process is created and started, including which API is used.
我已将其集成到 subprocess.Popen 的子类中，该子类应该在 Python 2 和 3 中都可以使用.Python 2 的用户会欣赏它是 Unicode，而不是使用的旧版 ANSI API通过 2.x 子进程.我还添加了创建暂停进程并稍后start 的功能.当您需要在执行之前将进程添加到 Job 对象时，这很有用.
I've integrated this into a subclass of subprocess.Popen that should work in both Python 2 and 3. Users of Python 2 will appreciate that it's Unicode as opposed to the legacy ANSI API that's used by 2.x subprocess. I also added the ability to create a process suspended and start it later. This is useful when you need to add a process to a Job object before it executes.
CreateProcessAsUser 通常从在 SYSTEM 帐户下运行的服务调用，该帐户具有所需的权限 SeAssignPrimaryTokenPrivilege.在 Vista 及更高版本中，您可以将此进程创建类型与本地 S4U(用户服务)或 Kerberos S4U 登录令牌一起使用(请参阅此问题)，这类似于任务计划程序在不存储密码的情况下以用户身份执行计划任务的方式.需要从具有 SeTcbPrivilege(受信任的计算机基础)的帐户(例如 SYSTEM)请求通过 LsaLogonUser 进行 S4U 登录.否则 LsaLogonUser 将只返回一个不能用于创建进程的标识令牌.
CreateProcessAsUser is normally called from a service that's running under the SYSTEM account, which has the required privilege SeAssignPrimaryTokenPrivilege. You can use this process creation type with a local S4U (service for user) or Kerberos S4U logon token in Vista and later (see this question), which is similar to how the Task Scheduler executes a scheduled task as a user without storing a password. An S4U logon via LsaLogonUser needs to be requested from an account with SeTcbPrivilege (trusted computer base), such as SYSTEM. Otherwise LsaLogonUser will return only an identification token that can't be used to create processes.
如果当前用户没有SeAssignPrimaryTokenPrivilege，那么你可以调用CreateProcessWithTokenW，它需要SeImpersonatePrivilege.管理员应该有这个权限.否则，您可以调用 CreateProcessWithLogonW，它不需要任何权限.令牌和登录创建类型还提供了在系统注册表中自动加载用户配置文件的选项.
If the current user doesn't have SeAssignPrimaryTokenPrivilege, then you can call CreateProcessWithTokenW, which instead requires SeImpersonatePrivilege. Administrators should have this privilege. Otherwise you can call CreateProcessWithLogonW, which doesn't require any privileges. The token and logon creation types also provide the option to automatically load the user's profile in the system registry.
我在下面包含的示例使用登录创建类型来运行 whoami.exe.它创建以标准输出作为管道挂起的进程；按回车键启动它；从标准输出读取；并获取退出代码.
The example that I've included below uses the logon creation type to run whoami.exe. It creates the process suspended with stdout as a pipe; starts it when you press enter; reads from stdout; and gets the exit code.
