文章讲述了在Selenium4.14.0版本中，由于对desired_capabilities参数的支持变化，如何使用ChromeOptions正确配置ChromeDriver以获取日志并执行网络请求的更新方法。

TypeError: WebDriver.__init__() got an unexpected keyword argument 'desired_capabilities'

新版本不支持desired_capabilities的问题解决

不同版本有不同的配置方法

历史版本设置方法，selenium==4.1.0

from selenium import webdriver

options = webdriver.ChromeOptions()
path = Service(r'C:\\chromedriver.exe')
caps = {"browserName": "chrome", 'goog:loggingPrefs': {'performance': 'ALL'}}  # 开启日志性能监听
driver = webdriver.Chrome(service=path, chrome_options=options,desired_capabilities=caps)

performance_log = driver.get_log('performance')  # 获取名称为 performance 的日志
    for i in range(len(performance_log)):
        message = json.loads(performance_log[i]['message'])
        message = message['message']['params']
        request = message.get('request')
        if(request is None):
            continue

        url = request.get('url')
        if(url == "https://xx.com"):
            # 通过requestId获取接口内容
            detail_response = driver.execute_cdp_cmd('Network.getResponseBody', {'requestId': message['requestId']})
    return detail_response

selenium == 4.14.0 就不支持上述设置方法

from selenium import webdriver

options = webdriver.ChromeOptions()
path = Service(r'C:\\chromedriver.exe')
options.set_capability('goog:loggingPrefs', {'performance': 'ALL'}) # 开启日志性能监听
driver = webdriver.Chrome(service=path, options=options)

performance_log = driver.get_log('performance')  # 获取名称为 performance 的日志
    for i in range(len(performance_log)):
        message = json.loads(performance_log[i]['message'])
        message = message['message']['params']
        request = message.get('request')
        if(request is None):
            continue

        url = request.get('url')
        if(url == "https://xx.com"):
            # 通过requestId获取接口内容
            detail_response = driver.execute_cdp_cmd('Network.getResponseBody', {'requestId': message['requestId']})
    return detail_response
