我有一个问题的代码，我承认我不明白发生了什么。我从下载页面13链接。到这一点self.img = driver.find_element(By.XPATH, self.link_photo)一切正常。进一步显示5后，它停止工作。它似乎是做一些奇怪的事情在这里。它似乎是做一些奇怪的在这里'self.imgURL = self.img.get_attribute（'srcset '。'.有人能帮我修复这段代码吗？非常感谢您的帮助。

# Download a link of each photo
    self.table_of_mini_photo = []
    for num, i in enumerate(range(1, int(self.total)+20)):
        self.link_photo = f'//*[@id="root"]/div[1]/div[2]/form/div[5]/div/div[2]/div[{i}]/a/div/div/div[1]/div[1]/div/img'
    # //*[@id="root"]/div[1]/div[2]/form/div[5]/div/div[2]/div[2]/a/div/div/div[1]/div[1]/div/img
    # //*[@id="root"]/div[1]/div[2]/form/div[5]/div/div[2]/div[3]/a/div/div/div[1]/div[1]/div/img

    # //*[@id="root"]/div[1]/div[2]/form/div[5]/div/div[2]/div[15]/a/div/div/div[1]/div[1]/div/img
        try:
            print(self.link_photo)
            self.img = driver.find_element(By.XPATH, self.link_photo)
            print(self.img)
            self.imgURL = self.img.get_attribute('srcset')
            print(self.imgURL)
            self.table_of_mini_photo.append(self.imgURL)
        except:
            pass

控制台结果确认我得到了13 ' selenium ：这是链接，但物理上我得到5。后面的代码注解是XPath，我下载。

我找到了一个简单的CSS选择器，它可以检索所有图像。

div[type='list'] > div > img

另外，你拉取的是srcset，它是同一张图片的不同大小的集合，如果你只需要一张图片，你可以直接拉取src，得到一张图片，这样你就不用解析字符串了。

self.imgURL = self.img.get_attribute('src')

更新后的代码只循环检索到的图像，获取并打印“src”，然后将其附加到列表中。

# Download a link of each photo
self.table_of_mini_photo = []
for img in driver.find_elements(By.CSS_SELECTOR, "div[type='list'] > div > img")
    imgURL = img.get_attribute('src')
    print(imgURL)
    self.table_of_mini_photo.append(imgURL)
