STEAMWORKS API - Python ctypes

Question

我正在尝试用我的 python 应用程序进行统计、排行榜、成就等。 我知道我正确连接到了 dll，但似乎无论我如何尝试调用这些函数。我收到一条错误消息，说它们不存在。 如果有人知道如何在没有 ctypes 和库之类的情况下做到这一点。我对任何解决方案都持开放态度。

有人可以帮忙吗，非常感谢。

steam_api.SteamAPI_SteamUserStats.restype = ctypes.POINTER(ISteamUserStats) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 属性错误：找不到函数“SteamAPI_SteamUserStats”

# Determine system architecture (32-bit or 64-bit)

else:
    steam_api_path = os.path.abspath('./steamworks/redistributable_bin/win32/steam_api.dll')

# Add directory containing steam_api DLL to PATH environment variable
os.environ['PATH'] = os.path.dirname(steam_api_path) + os.pathsep + os.environ.get('PATH', '')

# Load steam_api DLL
steam_api = ctypes.CDLL(steam_api_path)

    if not result:
        error_code = ctypes.get_last_error()
        raise RuntimeError(f'RequestCurrentStats failed with error code: {error_code}')

# Example usage
if __name__ == '__main__':
    try:
        steam_init()
        print("Steam API Initialized successfully.")

        request_current_stats()
        print("Current stats requested successfully.")

    except Exception as e:
        print(f"An error occurred: {str(e)}")

    finally:
        steam_shutdown()
        print("Steam API Shutdown.")

Answer 1

steam_api_flat.h

包含以下内容：

// A versioned accessor is exported by the library
S_API ISteamUserStats *SteamAPI_SteamUserStats_v012();
// Inline, unversioned accessor to get the current version.  Essentially the same as SteamUserStats(), but using this ensures that you are using a matching library.
inline ISteamUserStats *SteamAPI_SteamUserStats() { return SteamAPI_SteamUserStats_v012(); }

所以

SteamAPI_SteamUserStats

实际上并不是DLL的一部分。由于您没有使用 C 头文件，因此需要使用

SteamAPI_SteamUserStats_v012

来代替。
