for i, img_link in enumerate(img_links):
try:
response = requests.get(img_link)
if response.status_code == 200:
img = Image.open(BytesIO(response.content))
ext = img.format.lower()
if ext in ["png", "gif", "jpg", "jpeg"]:
file_path = os.path.join(os.path.expanduser("~"), "Desktop/TH", f"{i+1}.{ext}")
with open(file_path, "wb") as f:
f.write(response.content)
print(f"{i+1}.jpg 图片下载完成！")
else:
print("不支持的图片格式")
else:
print(f"请求失败，状态码：{response.status_code}")
except Exception as e:
print(f"下载第{i+1}张图片时出错：{e}")
continue
print("全部图片下载完成！")
这段代码默认将下载的图片保存在桌面的TH文件夹内。如需修改保存路径，请修改 os.path.join(os.path.expanduser("~"), "Desktop/TH", f"{i+1}.{ext}") 这一行的路径。之前看到的帖子都没有对图片类型以及报错进行处理，故我额外增加了一些代码，保证能正常运行下去
