如何从Python中的URL读取图像数据? [英] How do I read image data from a URL in Python?

问题描述

当我们处理本地文件时，我想做的事情很简单，但是当我尝试使用远程URL时，问题就来了.

What I'm trying to do is fairly simple when we're dealing with a local file, but the problem comes when I try to do this with a remote URL.

基本上，我正在尝试从从URL提取的文件中创建一个PIL图像对象.当然，我总是可以只获取URL并将其存储在临时文件中，然后将其打开到图像对象中，但这感觉效率很低.

Basically, I'm trying to create a PIL image object from a file pulled from a URL. Sure, I could always just fetch the URL and store it in a temp file, then open it into an image object, but that feels very inefficient.

这就是我所拥有的:

Image.open(urlopen(url))

它抱怨说seek()不可用，所以我尝试了这个:

It flakes out complaining that seek() isn't available, so then I tried this:

Image.open(urlopen(url).read())

但是那也不起作用.有没有更好的方法可以执行此操作，还是可以将这种方式写入临时文件?

But that didn't work either. Is there a Better Way to do this, or is writing to a temporary file the accepted way of doing this sort of thing?

推荐答案

在Python3中，StringIO和cStringIO模块不见了.

In Python3 the StringIO and cStringIO modules are gone.

在Python3中，您应该使用:

In Python3 you should use:

from PIL import Image
import requests
from io import BytesIO

response = requests.get(url)
img = Image.open(BytesIO(response.content))
