如何使用ctypes从进程中获取DLL的基址？

要从进程中获取DLL的基址，可以使用ctypes库结合Win API 函数 来实现。下面是一个使用ctypes从进程中获取DLL基址的示例代码：

import ctypes
from ctypes.wintypes import LPVOID, HANDLE, HMODULE, DWORD, BOOL
# 定义WinAPI函数类型
OpenProcess = ctypes.windll.kernel32.OpenProcess
OpenProcess.argtypes = [DWORD, BOOL, DWORD]
OpenProcess.restype = HANDLE
EnumProcessModules = ctypes.windll.kernel32.EnumProcessModules
EnumProcessModules.argtypes = [HANDLE, ctypes.POINTER(HMODULE), DWORD, ctypes.POINTER(DWORD)]
EnumProcessModules.restype = BOOL
GetModuleBaseName = ctypes.windll.psapi.GetModuleBaseNameA
GetModuleBaseName.argtypes = [HANDLE, HMODULE, ctypes.POINTER(ctypes.c_char), DWORD]
GetModuleBaseName.restype = DWORD
# 获取进程ID
pid = ctypes.windll.kernel32.GetCurrentProcessId()
# 打开进程
PROCESS_ALL_ACCESS = 0x1F0FFF
hProcess = OpenProcess(PROCESS_ALL_ACCESS, False, pid)
# 获取模块句柄
hModule = HMODULE * 1024
cbNeeded = DWORD()
EnumProcessModules(hProcess, hModule, ctypes.sizeof(hModule), ctypes.byref(cbNeeded))
# 获取DLL的基地址
for i in range(cbNeeded.value // ctypes.sizeof(HMODULE)):
    szModName = ctypes.create_string_buffer(255)
    GetModuleBaseName(hProcess, hModule[i], szModName, ctypes.sizeof(szModName))
    if szModName.value.decode().lower() == "your_dll_name.dll":
        dll_base_address = hModule[i]
        break
print("DLL base address: 0x{:X}".format(dll_base_address))
请确保将your_dll_name.dll替换为您要查找的DLL的名称。此代码将打开当前进程，遍历进程的模块，找到指定的DLL后，输出其基地址。
