在windows上使用python使用Selenium Webdriver截图时，截图直接保存到程序的路径下，有没有办法将.png文件保存到特定目录？
使用
driver.save_screenshot('/path/to/file')driver.get_screenshot_as_file('/path/to/file')import selenium.webdriver as webdriver
import contextlib
@contextlib.contextmanager
def quitting(thing):
yield thing
thing.quit()
with quitting(webdriver.Firefox()) as driver:
driver.implicitly_wait(10)
driver.get('http://www.google.com')
driver.get_screenshot_as_file('/tmp/google.png')
# driver.save_screenshot('/tmp/google.png')
受到此线程的启发（对于 Java 也是同样的问题）：使用 Selenium WebDriver 进行屏幕截图
from selenium import webdriver
browser = webdriver.Firefox()
browser.get('http://www.google.com/')
browser.save_screenshot('screenie.png')
browser.quit()
是的，我们有办法使用 python webdriver 获取 .png 的屏幕截图扩展名
如果您使用 python webriver，请使用下面的代码。它非常简单。
driver.save_screenshot('D\folder\filename.png')
driver.save_screenshot("path to save \\screen.jpeg")
这将截取屏幕截图并将其放置在所选名称的目录中。
import os
driver.save_screenshot(os.path.join(os.path.dirname(os.path.realpath(__file__)), 'NameOfScreenShotDirectory', 'PutFileNameHere'))
当然现在这不是真的，但我也遇到了这个问题和我的方式： 看起来“save_screenshot”在创建名称中带有空格的文件时遇到了一些麻烦，同时我向文件名添加了随机化以转义覆盖。
这里我有方法来清除文件名中的空格（如何用下划线替换空格，反之亦然？）：
def urlify(self, s):
# Remove all non-word characters (everything except numbers and letters)
s = re.sub(r"[^\w\s]", '', s)
# Replace all runs of whitespace with a single dash
s = re.sub(r"\s+", '-', s)
return s
然后
driver.save_screenshot('c:\\pytest_screenshots\\%s' % screen_name)
哪里
def datetime_now(prefix):
symbols = str(datetime.datetime.now())
return prefix + "-" + "".join(symbols)
screen_name = self.urlify(datetime_now('screen')) + '.png'
这里他们问了类似的问题，答案似乎更完整，我留下来源：
如何在Python中使用Selenium WebDriver截取部分屏幕截图？
from selenium import webdriver
from PIL import Image
from io import BytesIO
fox = webdriver.Firefox()
fox.get('http://stackoverflow.com/')
# now that we have the preliminary stuff out of the way time to get that image :D
element = fox.find_element_by_id('hlogo') # find part of the page you want image of
location = element.location
size = element.size
png = fox.get_screenshot_as_png() # saves screenshot of entire page
fox.quit()
im = Image.open(BytesIO(png)) # uses PIL library to open image in memory
left = location['x']
top = location['y']
right = location['x'] + size['width']
bottom = location['y'] + size['height']
im = im.crop((left, top, right, bottom)) # defines crop points
im.save('screenshot.png') # saves new cropped image
您可以使用以下函数作为相对路径，因为在脚本中添加绝对路径不是一个好主意
导入
import sys, os
使用如下代码：
ROOT_DIR = os.path.dirname(os.path.abspath(__file__))
screenshotpath = os.path.join(os.path.sep, ROOT_DIR,'Screenshots'+ os.sep)
driver.get_screenshot_as_file(screenshotpath+"testPngFunction.png")
确保创建 .py 文件所在的文件夹。
os.path.joinos.sepFile.separtorTakeScreenShot screenshot=new TakeScreenShot();
screenshot.screenShot("screenshots//TestScreenshot//password.png");
一定会成功的，请尝试。
看看下面的Python脚本，使用Chrome的selenium包web driver来拍摄FB主页。
脚本：
import selenium
from selenium import webdriver
import time
from time import sleep
chrome_browser = webdriver.Chrome()
chrome_browser.get('https://www.facebook.com/') # Enter to FB login page
sleep(5)
chrome_browser.save_screenshot('C:/Users/user/Desktop/demo.png') # To take FB homepage snap
chrome_browser.close() # To Close the driver connection
chrome_browser.quit() # To Close the browser
这很简单，请尝试一下：
from selenium import webdriver
driver = webdriver.Chrome()
def take_screenshot(name):
driver.get_screenshot_as_file(f"./screenshot/{name}.png")
#Or with datetime:
def take_screenshot_with_dt(name):
datetime.now()
screenDatetime = datetime.now().strftime('%d-%m-%Y-%H-%M')
driver.get_screenshot_as_file(f"./screenshot/{name}-{screenDatetime}.png")
take_screenshot("screenshotName")
take_screenshot_with_dt("screenshotNameDt")
将此钩子写在
conftest.py@pytest.hookimpl(hookwrapper=True)
def pytest_runtest_makereport(item):
pytest_html = item.config.pluginmanager.getplugin("html")
outcome = yield
report = outcome.get_result()
extra = getattr(report, "extra", [])
if report.when == "call":
# always add url to report
extra.append(pytest_html.extras.url(driver.current_url))
xfail = hasattr(report, "wasxfail")
if (report.skipped and xfail) or (report.failed and not xfail):
report_directory = os.path.dirname(item.config.option.htmlpath)
file_name = report.nodeid.replace("::", "_") + ".png"
destination_file = os.path.join(report_directory, file_name)
driver.save_screenshot(destination_file)
if file_name:
html = '<div><img src="%s" alt="screenshot" style="width:300px;height=200px"'\
'onclick="window.open(this.src)" align="right"/></div>'%file_name
# only add additional html on failure
extra.append(pytest_html.extras.html(html))
report.extra = extra
在 Django 中，您可以在无头 Google Chrome、Microsoft Edge 和 Firefox 上截取 Django Admin 的屏幕截图，如下所示。 *我使用 pytest-django 和 selenium 和 我的回答解释了如何在无头浏览器上一起执行此操作：
import pytest
from selenium import webdriver
def take_screenshot(driver, name):
os.makedirs(os.path.join("screenshot", os.path.dirname(name)), exist_ok=True)
driver.save_screenshot(os.path.join("screenshot", name))
def test_1(live_server):
options = webdriver.ChromeOptions()
options.add_argument("--headless=new")
driver = webdriver.Chrome(options=options)
driver.set_window_size(1024, 768)
driver.get(("%s%s" % (live_server.url, "/admin/")))
take_screenshot(driver, "admin/chrome.png")
assert "Log in | Django site admin" in driver.title
import pytest
from selenium import webdriver
def take_screenshot(driver, name):
os.makedirs(os.path.join("screenshot", os.path.dirname(name)), exist_ok=True)
driver.save_screenshot(os.path.join("screenshot", name))
def test_1(live_server):
options = webdriver.EdgeOptions()
options.add_argument("--headless=new")
driver = webdriver.Edge(options=options)
driver.set_window_size(1024, 768)
driver.get(("%s%s" % (live_server.url, "/admin/")))
take_screenshot(driver, "admin/edge.png")
assert "Log in | Django site admin" in driver.title
import pytest
from selenium import webdriver
def take_screenshot(driver, name):
os.makedirs(os.path.join("screenshot", os.path.dirname(name)), exist_ok=True)
driver.save_screenshot(os.path.join("screenshot", name))
def test_1(live_server):
options = webdriver.FirefoxOptions()
options.add_argument("-headless")
driver = webdriver.Firefox(options=options)
driver.set_window_size(1024, 768)
driver.get(("%s%s" % (live_server.url, "/admin/")))
take_screenshot(driver, "admin/firefox.png")
assert "Log in | Django site admin" in driver.title
WebDriver driver = new FirefoxDriver();
driver.get("http://www.google.com/");
File scrFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
FileUtils.copyFile(scrFile, new File("c:\\NewFolder\\screenshot1.jpg"));
我知道你正在寻找 python 中的答案，但这里是如何在 ruby 中做到这一点..
http://watirwebdriver.com/screenshots/
如果这只能通过保存在当前目录中来实现。我会首先将图像分配给一个变量，然后将该变量作为 PNG 文件保存到磁盘。
例如：
image = b.screenshot.png
File.open("testfile.png", "w") do |file|
file.puts "#{image}"
end
其中 b 是 webdriver 使用的浏览器变量。我可以灵活地在“File.open”中提供绝对或相对路径，这样我就可以将图像保存在任何地方。
