如何在Selenium中获取图像URI？ [英] How to get image URI in Selenium?

问题描述

我对这个问题使用了第一个答案，以便使其适应我的需要：自动在笔记本电脑上保存指定网址的图片。

我的问题是如何获取网页上存在的每个图像的URI，以正确完成我的代码：

$ b

I used the first answer to this question in order to adapt it to my need: saving pictures of a given URL on my laptop automatically.

My problem is how to get the URI of every image that exist on the webpage in order to complete my code correctly:

 import selenium
    class TestFirefox:
        def testFirefox(self):
            self.driver=webdriver.Firefox()
            # There are 2 pictures on google.com, I want to download them
            self.driver.get("http://www.google.com")
            self.l=[] # List to store URI to my images
            self.r=self.driver.find_element_by_tag_name('img')
            # I did print(self.r) but it does not reflect the URI of 
            # the image: which is what I want.

            # What can I do to retrieve the URIs and run this:
            self.l.append(self.image_uri)
            for uri_to_img in self.l:
               self.driver.get(uri_to_img)

               # I want to download the images, but I am not sure 
               # if this is the good way to proceed since my list's content
               # may not be correct for the moment 
               self.driver.save_screenshot(uri_to_image)
               driver.close()
    if __name__=='__main__':
        TF=TestFirefox()
        TF.testFirefox()

推荐答案

得到给定图像的 src 属性，以确定它的名称和（可能）地址 - 记住， src 也可以是相对URI。

You need to get get src attribute of the given image in order to determine it's name and (possibly) address - remember, src can be also relative URI.

for img in self.l:
    url = img.get_attribute("src")

您应该尝试简单的HTTP客户端，比如 urllib

For downloading image you should try simple HTTP client like urllib

import urllib.request  

urllib.request.urlretrieve(url, "image.png")
