使用Python获取实际的Facebook和Twitter图像URL [英] Getting actual facebook and twitter image urls using python

问题描述

我想编写一个python代码，从包含图片的网址中下载主"图片.

I want to write a python code that downloads 'main' image from urls that contain images.

我的数据(文本文件)中有这样的网址

I have urls like these in my data (text files)

1. http://t.co/fd9F0Gp1P1

指向fb图片

1. http://t.co/0Ldy6j26fb

指向Twitter图片

points to twitter image

，但其扩展的网址不会产生.jpg，.png图片.相反，他们将我们定向到包含所需图像的页面.

but their expanded urls don't result in .jpg,.png images. Instead they direct us to a page that contains the desired image.

如何从这些URL下载图像?

How do I download images from these urls?

推荐答案

在这里，您将找到一个示例，说明我如何从Facebook页面下载飞机图像，您可以对其进行调整以使其适用于您的Twitter页面:

Here you will find an example of how I downloaded the plane image from the facebook page, you can adapt this to work for your twitter page:

from bs4 import BeautifulSoup
import urllib

urlData = urllib.urlopen('https://www.facebook.com/photo.php?fbid=10152055005350906')
data = str(urlData.readlines())
bs = BeautifulSoup(data)
imgUrl = bs.find('img', attrs={'class': 'fbPhotoImage img'}).get('src')
urllib.urlretrieve(imgUrl, "plane.jpg")

编辑

我决定也实际帮助您处理Twitter，这是从您提供的链接下载图像的Twitter示例:

EDIT

I decided to actually help you out with the twitter one as well, here is the twitter example of downloading the image from the link you gave:

from bs4 import BeautifulSoup
import urllib

urlData = urllib.urlopen('https://twitter.com/USABillOfRights/status/468852515409502210/photo/1')
data = str(urlData.readlines())
bs = BeautifulSoup(data)
imgUrl = bs.find('img', attrs={'alt': 'Embedded image permalink'}).get('src')
urllib.urlretrieve(imgUrl, "cnn.jpg")

这是 BeautifulSoup的网络参考.
