一旦通过 Selenium 和 Python 调用 click() 方法，控制台就会充满 DEBUG 消息
Console is getting flooded with DEBUG messages once click() method is invoked through Selenium and Python
我正在使用 selenium firefox，下面的代码生成了我需要的内容，但在完成加载后生成了大量调试消息。我做错了什么？
def count_list(self, busienss_seller_url):
seller_url = busienss_seller_url
driver.get(seller_url)
while True:
load_content = driver.find_element_by_xpath('/html/body/div[5]/div[3]/div/button')
try:
load_content.click()
time.sleep(3)
except:
print('Finish loading...')
break
links = driver.find_elements_by_class_name("title-link")
number_of_links = []
for link in links:
ad_links = link.get_attribute('href')
number_of_links.append(ad_links)
driver.close()
'count ads - return how many links are in the list'
return len(number_of_links)

很难猜测这些消息块的原因，但从日志中可以清楚地看出：
- 您已将 WebDriver 实例配置为在控制台上打印
DEBUG 消息，或者这是默认配置。
粗略的click()事件触发同步JavaScript的执行：
"POST /session/7229021d-dce2-4653-bea9-7cd29732d83a/execute/sync HTTP/1.1" 200 150
JavaScript 的执行是在当前选定帧或 window 的上下文中进行的。
- 提供的脚本片段将作为匿名函数的主体执行。
- 在脚本中，使用 document 来引用当前文档。
- 一旦脚本执行完毕，局部变量将不可用，但全局变量将持续存在。
结论
如果你想摆脱控制台上的 DEBUG 消息你必须配置 WebDriver 实例传递key, value 对如下：
browser = webdriver.Ie(capabilities=cap, executable_path="C:\Utility\BrowserDrivers\IEDriverServer.exe", log_level='TRACE', log_file='./Logs/IEDriver_Arg.log')
我不完全确定这是你需要的，但this question似乎和我非常相似。区别在于日志文件被淹没而不是控制台。
简而言之，解决方案是通过这样做来提高 selenium 的日志记录级别：
# Set the threshold for selenium to WARNING
from selenium.webdriver.remote.remote_connection import LOGGER as seleniumLogger
seleniumLogger.setLevel(logging.WARNING)

- 您已将 WebDriver 实例配置为在控制台上打印
DEBUG消息，或者这是默认配置。 粗略的
click()事件触发同步JavaScript的执行："POST /session/7229021d-dce2-4653-bea9-7cd29732d83a/execute/sync HTTP/1.1" 200 150JavaScript 的执行是在当前选定帧或 window 的上下文中进行的。
- 提供的脚本片段将作为匿名函数的主体执行。
- 在脚本中，使用 document 来引用当前文档。
- 一旦脚本执行完毕，局部变量将不可用，但全局变量将持续存在。
结论
如果你想摆脱控制台上的 DEBUG 消息你必须配置 WebDriver 实例传递key, value 对如下：
browser = webdriver.Ie(capabilities=cap, executable_path="C:\Utility\BrowserDrivers\IEDriverServer.exe", log_level='TRACE', log_file='./Logs/IEDriver_Arg.log')
我不完全确定这是你需要的，但this question似乎和我非常相似。区别在于日志文件被淹没而不是控制台。 简而言之，解决方案是通过这样做来提高 selenium 的日志记录级别：
# Set the threshold for selenium to WARNING
from selenium.webdriver.remote.remote_connection import LOGGER as seleniumLogger
seleniumLogger.setLevel(logging.WARNING)
