使用Telethon非机器人账户向Telegram群组发图报错求助

• 使用Telethon个人非机器人账户向Telegram群组发送图片时触发MediaEmptyError
• 已尝试将图片移至代码目录，问题未解决
• 报错信息：

telethon.errors.rpcerrorlist.MediaEmptyError: The provided media object is invalid or the current account may not be able to send it (such as games as users) (caused by SendMediaRequest)

• 涉事代码：

filenames = ['C:\Users\Achak\Documents\GitHub\typhoone\qq\0.jpg','C:\Users\Achak\Documents\GitHub\typhoone\qq\1.jpg']
for filename in filenames:
    try:
        # Upload the file
        result = await client.upload(filename)
        media = InputMediaPhoto(result)

        # Send the file to the group
        await client.send_file(group, media)
        print(f'Sent {filename} to group with ID {group_id}')
    except PeerFloodError:
        print('Sending too many messages, stopping...')
        break

1. 修复路径转义问题
   Windows路径中的\是转义字符，会导致路径解析错误。两种修正方式：

   • 使用原始字符串（路径前加r）：

     filenames = [r'C:\Users\Achak\Documents\GitHub\typhoone\qq\0.jpg', r'C:\Users\Achak\Documents\GitHub\typhoone\qq\1.jpg']
     

   • 改用双反斜杠：

     filenames = ['C:\\Users\\Achak\\Documents\\GitHub\\typhoone\\qq\\0.jpg','C:\\Users\\Achak\\Documents\\GitHub\\typhoone\\qq\\1.jpg']
     

2. 简化send_file调用
   Telethon的send_file方法支持直接传入本地文件路径，无需手动调用upload和创建InputMediaPhoto，多余步骤易引发错误。修改后代码：

filenames = [r'C:\Users\Achak\Documents\GitHub\typhoone\qq\0.jpg', r'C:\Users\Achak\Documents\GitHub\typhoone\qq\1.jpg']
for filename in filenames:
    try:
        await client.send_file(group, filename)
        print(f'Sent {filename} to group with ID {group_id}')
    except PeerFloodError:
        print('Sending too many messages, stopping...')
        break

3. 验证基础条件

• 确认图片文件未损坏，用图片查看器能正常打开
• 检查个人账号是否有权限向目标群组发送消息（未被禁言、已加入群组）
