问题描述
我正在尝试使用 python 中的氦拍摄页面中特定元素的快照,这是我的代码
from selenium.webdriver.chrome.options import Options
from helium import *
url = 'exampleurl'
options = Options()
options.binary_location = "C:/Program Files/Google/Chrome/Application/chrome.exe"
browser = start_chrome(url,headless=False,options=options)
#.FindElementById("viewPane").ScrollIntoView True
element = browser.find_element_by_xpath("//*[@id='frmCaseNo']/div[2]/img")
#element.get_screenshot_as_file("Number.png")
#element.screenshot('Number.png')
#element.save_screenshot('Number.png')
#get_driver().save_screenshot('Number.png')
get_driver().element.save_screenshot('Number.png')
此行成功使用氦 get_driver().save_screenshot('Number.png')
但此行不处理特定元素。如何处理特定元素并对其进行快照?
解决方法
Helium 也暴露了所有的 selenium 方法,所以如果你检查 webelement 类
你可以看到有一个方法被调用
webelement.screenshot("hellium.png")
,将元素截图保存为 helium.png
所以在你的情况下使用:
element = browser.find_element_by_xpath("//*[@id='frmCaseNo']/div[2]/img")
browser.execute_script("arguments[0].scrollIntoView();",element)
element.screenshot("Number.png")
element.screenshot("hellium.png")
完整代码:
from helium import *
from selenium.webdriver.chrome.options import Options
from shutil import copyfile
#copying it to current directory so that you don't have to do it
copyfile(r"C:\Users\Downloads\chromedriver.exe","chromedriver.exe")
options=Options()
options.binary_location = r"C:\Program Files\Google\Chrome\Application\chrome.exe"
browser = start_chrome("https://www.google.com",options=options)
browser.find_element_by_xpath("//body").screenshot("test.png")
,
我通过裁剪特定元素找到了一种解决方法,但我欢迎任何其他想法(也许有更简单的解决方案)
from selenium.webdriver.chrome.options import Options
from helium import *
from PIL import Image
myCaseNumber = '181564540'
url = 'https://eservices.moj.gov.kw/searchPages/searchCases.jsp'
options = Options()
options.binary_location = "C:/Program Files/Google/Chrome/Application/chrome.exe"
browser = start_chrome(url,headless=False,options=options)
element = browser.find_element_by_xpath("//*[@id='frmCaseNo']/div[2]/img")
browser.execute_script("arguments[0].scrollIntoView();",element)
location = element.location
size = element.size
get_driver().save_screenshot('Temp.png')
x = location['x']
y = location['y']
width = location['x']+size['width']
height = location['y']+size['height']
im = Image.open('Temp.png')
im = im.crop((int(x),int(y),int(width),int(height)))
im.save('Number.png')
