英文:

can't use send images in functions in discord bot in cogs

问题

for some reason it seems that i cant send images with this

```python
@commands.Cog.listener()
async def on_message(self, message):
     if str(message.content).lower == "pic" :
         await message.send("text", file=discord.File('picture.png'))

i thought the problem was in the function on_message itself
after i saw the documentation i figured out that i can send it only with

channel.send(file=discord.file('pic.png'))

so i tried this

@commands.Cog.listener()
async def on_message(self, message):
     channel = self.client.get_channel("channel id")
     if str(message.content).lower == "pic" :
         await channel.send("text", file=discord.File('picture.png'))

it didn't work as i thought

**得分**: 0

&gt; 首先，当检查消息内容的小写版本是否等于 "pic" 时，你需要调用 lower() 方法将其转换为小写。目前，你缺少了括号，所以比较不会正确工作。修改条件为 str(message.content).lower() == "pic"。

&gt; 其次，当发送带有文件附件的消息时，应该使用 await message.channel.send() 方法，而不是 await message.send()。调整你的代码以使用 await message.channel.send("text", file=discord.File('picture.png'))。

**以下是你的代码的修复版本！:**

@commands.Cog.listener()
async def on_message(self, message):
if str(message.content).lower() == "pic":
await message.channel.send("text", file=discord.File('picture.png'))

尝试一下，然后告诉我结果。

&gt; First, when checking if the lowercase version of the message content is equal to &quot;pic,&quot; you need to call the lower() method to convert it to lowercase. Currently, you&#39;re missing the parentheses, so the comparison won&#39;t work correctly. Modify the condition to str(message.content).lower() == &quot;pic&quot;.

&gt; Second, when sending a message with a file attachment, you should use the await message.channel.send() method instead of await message.send(). Adjust your code to use await message.channel.send(&quot;text&quot;, file=discord.File(&#39;picture.png&#39;)).

**Here is the Fixed version of your code !:**

@commands.Cog.listener()
async def on_message(self, message):
if str(message.content).lower() == "pic":
await message.channel.send("text", file=discord.File('picture.png'))

try it and tell me.
