好了，终于明白了：
from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
# enable browser logging
d = DesiredCapabilities.CHROME
d['loggingPrefs'] = { 'browser':'ALL' }
driver = webdriver.Chrome(desired_capabilities=d)
# load the desired webpage
driver.get('http://foo.com')
# print messages
for entry in driver.get_log('browser'):
print(entry)
source字段相等的条目'console-api'对应于控制台消息，消息本身存储在该message字段中。
从chromedriver 75.0.3770.8开始，您必须使用goog：loggingPrefs而不是loggingPrefs：
d['goog:loggingPrefs'] = { 'browser':'ALL' }
