所以我有一个与我一起学习Python的不和谐机器人。我有一个下载图像,编辑/合并它们的命令,然后将编辑后的图像发送到聊天室。我以前使用requests
来执行此操作,但是我被一个图书馆开发人员告知discord.py我应该使用aiohttp
而不是requests
。我无法找到如何在aiohttp
中下载图片,我尝试了很多东西,但都没有。
if message.content.startswith("!async"):
import aiohttp
import random
import time
import shutil
start = time.time()
notr = 0
imagemake = Image.new("RGBA",(2048,2160))
imgsave = "H:\Documents\PyCharmProjects\ChatBot\Images"
imagesend = os.path.join(imgsave,"merged.png")
imgmergedsend =os.path.join(imgsave,"merged2.png")
with aiohttp.ClientSession() as session:
async with session.get("http://schoolido.lu/api/cards/788/") as resp:
data = await resp.json()
cardsave = session.get(data["card_image"])
with open((os.path.join(imgsave, "card.png")),"wb") as out_file:
shutil.copyfileobj(cardsave, out_file)
是我现在所拥有的,但仍然无法奏效。
那么,有没有办法下载图片?

我刚才想出来了:
if message.content.startswith("!async2"):
import aiohttp
with aiohttp.ClientSession() as session:
async with session.get("http://schoolido.lu/api/cards/788/") as resp:
data = await resp.json()
card = data["card_image"]
async with session.get(card) as resp2:
test = await resp2.read()
with open("cardtest2.png", "wb") as f:
f.write(test)
我收到了回复,而非图片回复

您在写入文件时锁定循环。您需要使用aiofiles。
import aiohttp
import aiofiles
async with aiohttp.ClientSession() as session:
url = "http://host/file.img"
async with session.get(url) as resp:
if resp.status == 200:
f = await aiofiles.open('/some/file.img', mode='wb')
await f.write(await resp.read())
await f.close()
