完整实现步骤
1. 环境配置
首先需要安装必要的依赖包:
pip install selenium
pip install webdriver_manager
pip install pandas
2. 下载 ChromeDriver
访问 Chrome for Testing 下载对应版本的 ChromeDriver。确保 ChromeDriver 版本与您的 Chrome 浏览器版本匹配。
3. 启动调试模式的 Chrome
创建一个批处理文件来启动调试模式的 Chrome:
@echo off
start C:\software\chrome-win64\chrome.exe --remote-debugging-port=9223
4. 配置 Chrome 选项
def setup_chrome_options(self):
options = webdriver.ChromeOptions()
user_agent = 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36'
options.add_argument(f'user-agent={user_agent}')
options.add_argument('--disable-gpu')
options.add_argument('--no-sandbox')
options.add_argument('--disable-dev-shm-usage')
options.add_experimental_option("debuggerAddress", "localhost:9223")
return options
5. 实现搜索功能
def search_tweets(self, search_query):
"""
搜索并获取推文数据
"""
self.browser.switch_to.new_window('tab')
url = "https://x.com/explore"
self.browser.get(url=url)
# 定位搜索框
search_box = self.browser.find_element(
By.CSS_SELECTOR,
'[data-testid="SearchBox_Search_Input"]'
)
# 清空搜索框并输入搜索词
search_box.send_keys(Keys.CONTROL + "a")
search_box.send_keys(Keys.DELETE)
self.browser.implicitly_wait(20)
search_box.send_keys(search_query)
search_box.send_keys(Keys.RETURN)
6. 监控网络响应
def monitor_network(self):
"""
监控浏览器网络响应
"""
performance_log = self.browser.get_log("performance")
for packet in performance_log:
message = json.loads(packet.get("message")).get("message")
if "Network" in message.get("method") and 'SearchTimeline' in msg:
document_url = message['params'].get('documentURL')
if document_url and '&f=live' in document_url:
request_id = message.get("params").get("requestId")
# 处理请求数据
7. 数据提取与处理
def extract_tweet_data(self, entries):
"""
从响应中提取推文数据
"""
tweets = []
for entry in entries:
item_content = entry['content'].get('itemContent', '')
if not item_content:
continue
tweet_result = entry['content']['itemContent']['tweet_results']['result']
tweets.append({
'id': tweet_result.get('id_str'),
'text': tweet_result.get('text'),
'created_at': tweet_result.get('created_at'),
'author': tweet_result.get('user'),
'metrics': tweet_result.get('public_metrics')
})
return tweets
