python - 没有名为“websockets.legacy”的模块

问题描述

我正在尝试使用 auto-py-to-exe 构建一个 exe。Exe 构建成功，但现在我的 websocket 服务器程序无法正常工作。如果有人知道此问题的解决方案，请告诉我。

代码：

import asyncio
import websockets
import win32gui
import win32ui
import win32con
import win32com.client
import win32api
import json
from PIL import Image, ImageFile
import io
import time

shell = win32com.client.Dispatch('WScript.Shell')

ImageFile.MAXBLOCK = 2**20

def left_click(pos_x, pos_y):
  win32api.SetCursorPos((pos_x, pos_y))
  win32api.mouse_event(win32con.MOUSEEVENTF_LEFTDOWN, pos_x, pos_y, 0, 0)
  win32api.mouse_event(win32con.MOUSEEVENTF_LEFTUP, pos_x, pos_y, 0, 0)

def right_click(pos_x, pos_y):
  win32api.SetCursorPos((pos_x, pos_y))
  win32api.mouse_event(win32con.MOUSEEVENTF_RIGHTDOWN, pos_x, pos_y, 0, 0)
  win32api.mouse_event(win32con.MOUSEEVENTF_RIGHTUP, pos_x, pos_y, 0, 0)
    
async def echo(websocket, path):
 while True:
    try:
        raw_data = await websocket.recv()
        data = json.loads(raw_data)
        if data['type'] == 'click':
            pos_x = data['x']
            pos_y = data['y']
            if data['click_type'] == 1:
              left_click(pos_x, pos_y)
            elif data['click_type'] == 2:
              left_click(pos_x, pos_y)
              left_click(pos_x, pos_y)
            elif data['click_type'] == 3:
              right_click(pos_x, pos_y)
            else:
              pass
        if data['type'] == 'keydown':
            cmd = ''
            
            if data['shiftKey']:
              cmd += '+'

            if data['ctrlKey']:
              cmd += '^'

            if data['altKey']:
              cmd += '%'

            if len(data['key']) == 1:
              cmd += data['key'].lower()
            else:
              cmd += '{'+data['key'].upper()+'}'

            shell.SendKeys(cmd)
    except websockets.ConnectionClosed as exc:
        pass
    except Exception as ex:
        pass
    try:
        PREV_IMG = None
        hdesktop = win32gui.GetDesktopWindow()

        width = win32api.GetSystemMetrics(win32con.SM_CXVIRTUALSCREEN)
        height = win32api.GetSystemMetrics(win32con.SM_CYVIRTUALSCREEN)
        left = win32api.GetSystemMetrics(win32con.SM_XVIRTUALSCREEN)
        top = win32api.GetSystemMetrics(win32con.SM_YVIRTUALSCREEN)

        # device context
        desktop_dc = win32gui.GetWindowDC(hdesktop)
        img_dc = win32ui.CreateDCFromHandle(desktop_dc)

        # memory context
        mem_dc = img_dc.CreateCompatibleDC()

        screenshot = win32ui.CreateBitmap()
        screenshot.CreateCompatibleBitmap(img_dc, width, height)
        mem_dc.SelectObject(screenshot)

        bmpinfo = screenshot.GetInfo()

        # copy into memory 
        mem_dc.BitBlt((0, 0), (width, height), img_dc, (left, top),win32con.SRCCOPY)

        bmpstr = screenshot.GetBitmapBits(True)

        pillow_img = Image.frombytes('RGB',
          (bmpinfo['bmWidth'], bmpinfo['bmHeight']),
          bmpstr, 'raw', 'BGRX')
        with io.BytesIO()as image_data:
            pillow_img.save(image_data, "JPEG", quality=80, optimize=True, progressive=True)
            image_data_content = image_data.getvalue()

        if image_data_content!= PREV_IMG:
            await websocket.send(image_data_content)
        PREV_IMG = image_data_content
        mem_dc.DeleteDC()
        win32gui.DeleteObject(screenshot.GetHandle())

    except websockets.ConnectionClosed as exc:
        pass
    except Exception as ex:
        pass

    

async def main():
  async with websockets.serve(echo, "", 9999):
    await asyncio.Future()  # run forever

asyncio.run(main())

该程序是为 rdp 和 vnc 制作的，它使用 websockets 成为服务器，然后客户端可以通过连接到计算机来访问计算机。
