Question

最近我发布了这个问题作为How to use Selenium Safari Webdriver问题的可能答案。我的答案的问题是当我运行python脚本并且我想禁用它时，从jar文件中记录出现在终端中。可以通过python完成吗？

在Mac OSX上使用Python 2.7.5和python模块selenium（2.41.0）。

此示例打开Safari浏览器并进行出价：

# -*- coding: utf-8 -*-

print '''
Python Selenium Safari Example
'''

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
import os

# path to selenium server standalone jar, downloaded here:
# http://docs.seleniumhq.org/download/
# or a direct url:
# http://selenium-release.storage.googleapis.com/2.41/selenium-server-standalone-2.41.0.jar
os.environ["SELENIUM_SERVER_JAR"] = "selenium-server-standalone-2.41.0.jar"
# note: I've put this jar file in the same folder as this python file

browser = webdriver.Safari()

# makes the browser wait if it can't find an element
browser.implicitly_wait(10)

browser.get("http://google.com/")

search_input = browser.find_element_by_css_selector("#gbqfq")
search_input.send_keys("python SELENIUM_SERVER_JAR turn logging off")
search_input.send_keys(Keys.RETURN)

raw_input("Press Enter to close...")

browser.quit()

但这是我运行时终端中出现的内容：

$ python selenium_safari_example.py

当我想要出现的唯一一件事是：

$ python selenium_safari_example.py

Python Selenium Safari Example

Press Enter to close...
$

如何阻止这些硒日志出现在终端？

Answer 1

从Safari webdriver.py看起来你可以传递quiet布尔参数，该参数传递给service.py中的服务对象，所有stdout和stderr都会转到/ dev / null

kwargs = dict()
if self.quiet:
    devnull_out = open(devnull, 'w')
    kwargs.update(stdout=devnull_out,
                  stderr=devnull_out)

从上面的代码中更改此内容：

browser = webdriver.Safari()

到此：

browser = webdriver.Safari(quiet=True)

Answer 2

我使用-D传递VM arg并在新文件中写入Selenium的debbug。

e.g。 java -jar -Dselenium.LOGGER=log.txt selenium-server-standalone-2.44.0.jar

Answer 3

我在Selenium用户论坛上找到了an answer的Java驱动程序：

    if (driver instanceof RemoteWebDriver) {
          ((RemoteWebDriver) driver).setLogLevel(Level.WARNING);
    }

在创建驱动程序对象后立即使用此命令解决了我的日志详细程度问题。也许你可以适应Python。
