Python Selenium Safari，禁用日志记录

Question

最近我发布了这个作为问题How to use Selenium Safari Webdriver 的可能答案。我的答案的问题是，当我运行 python 脚本时，来自 jar 文件的日志记录出现在终端中，我想禁用它。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)。

此示例打开一个 Safari 浏览器并按照我的要求进行操作：

# -*- 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()

但这是我运行终端时出现的内容：

$ python selenium_safari_example.py

当我只想出现这样的事情时：

$ python selenium_safari_example.py

Press Enter to close...
$

如何阻止这些 selenium 日志出现在终端中？

Answer 1

我使用-D 传递VM arg 并将Selenium 的调试写入新文件中。

例如java -jar -Dselenium.LOGGER=log.txt selenium-server-standalone-2.44.0.jar

Answer 2

从 Safari webdriver.py 看来，您可以传递 quiet 布尔参数，该参数已传递给 service.py 中的服务对象，所有 stdout 和 stderr 都将转到 /dev/null

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

从你上面的代码中改变这个：

browser = webdriver.Safari()

到这里：

browser = webdriver.Safari(quiet=True)

Answer 3

我在 Java 驱动程序的 Selenium 用户论坛上找到了 an answer：

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

在创建驱动程序对象后使用此命令解决了我的日志冗长问题。也许您可以将其改编为 Python。
