写了一段能发送图片的方法，支持window端

[AmicBeam]

思路就是将图片塞到剪切板里再ctrl+v出来

import json
import time
import io
import requests
from pynput.keyboard import Controller, Key # pip install pynput
from PIL import Image # pip install Pillow
import win32clipboard # pip install pywin32

keyboard = Controller()
imageCache = {}

def setClipboardData(image_data):
    win32clipboard.OpenClipboard()
    win32clipboard.EmptyClipboard()
    win32clipboard.SetClipboardData(win32clipboard.CF_DIB, image_data)
    win32clipboard.CloseClipboard()

def loadImage(image_url):
    if image_url not in imageCache:
        response = requests.get(image_url)
        img = Image.open(io.BytesIO(response.content))
        output = io.BytesIO()
        img.convert("RGB").save(output, "BMP")
        data = output.getvalue()[14:]
        output.close()
        imageCache[image_url] = data
    data = imageCache[image_url]
    return data
    
def sendImage(image_url):
    setClipboardData(loadImage(image_url))
    time.sleep(0.1)
    keyboard.press(Key.ctrl)
    keyboard.press('v')
    keyboard.release('v')
    keyboard.release(Key.ctrl)
    time.sleep(0.1)
    keyboard.press(Key.enter)
    time.sleep(0.1)
    keyboard.release(Key.enter)

谢谢老哥的思路。
拓展了一下功能，可以回复多个群聊的消息，用的时候聊天窗口的”合并会话窗口“的勾要去掉。
