Selenium 获取请求日志

import json
from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
import time
caps = {
    'browserName': 'chrome',
    'loggingPrefs': {
        'browser': 'ALL',
        'driver': 'ALL',
        'performance': 'ALL',
    },

        },

    },
}
driver = webdriver.Chrome(desired_capabilities=caps)
driver.get('https://partner.oceanengine.com/union/media/login/')
# 必须等待一定的时间，不然会报错提示获取不到日志信息，因为絮叨等所有请求结束才能获取日志信息
time.sleep(3)
request_log = driver.get_log('performance')
print(request_log)
for i in range(len(request_log)):
    message = json.loads(request_log[i]['message'])
    message = message['message']['params']
    # .get() 方式获取是了避免字段不存在时报错
    request = message.get('request')
    if(request is None):
        continue
    url = request.get('url')
    if(url == "https://s3.pstatp.com/bytecom/resource/union_web2/media/manifest.json"):
        # 得到requestId
        print(message['requestId'])
        # 通过requestId获取接口内容
        content = driver.execute_cdp_cmd('Network.getResponseBody', {'requestId': message['requestId']})
        print(content)
        break
