import discord
import aiohttp

client = discord.Client()

@client.event
async def on_message(message):
    if message.content.startswith('!add_value'):
        # 获取要添加的值
        value = message.content.split(' ')[1]
        
        # 向字符串添加值
        new_string = 'Hello ' + value
        
        # 发送HTTP请求
        async with aiohttp.ClientSession() as session:
            async with session.get('https://example.com', params={'string': new_string}) as response:
                # 处理响应
                if response.status == 200:
                    await message.channel.send('值已成功添加到字符串中！')
                else:
                    await message.channel.send('添加值时出现错误！')
