WebFetchPlus 是一个强大的智能网页抓取工具，能够根据URL类型自动选择最佳的抓取策略：
# 自动识别并抓取
skill webfetch-plus "https://x.com/elonmusk/status/123456789"
# 抓取抖音视频
skill webfetch-plus "https://v.douyin.com/xxxxx"
# 搜索Twitter
skill webfetch-plus --search "AI news"
# 批量抓取
skill webfetch-plus --batch urls.txt
# 指定策略
skill webfetch-plus "https://example.com" --strategy firecrawl
# JSON输出
skill webfetch-plus "https://x.com/OpenAI" --json
from webfetch_plus import WebFetchPlus
# 初始化
fetcher = WebFetchPlus()
# 抓取推文
result = fetcher.fetch("https://x.com/elonmusk/status/123456789")
print(result["text"])
print(result["author"]["username"])
# 搜索Twitter
results = fetcher.search_twitter("GPT-4", max_results=20)
for tweet in results["results"]:
print(f"@{tweet['author']['username']}: {tweet['text']}")
# 批量抓取
urls = ["url1", "url2", "url3"]
results = fetcher.batch_fetch(urls)
# 获取用户信息
user = fetcher.fetch("https://x.com/OpenAI")
print(f"{user['name']} - {user['metrics']['followers_count']} followers")

# 添加自定义抓取策略
from webfetch_plus import WebFetchPlus, FetchStrategy
fetcher = WebFetchPlus()
fetcher.add_strategy(
FetchStrategy.CUSTOM,
patterns=[r'custom\.site\.com'],
handler=my_custom_handler
)
# 添加请求中间件
def auth_middleware(request):
request.headers["Authorization"] = "Bearer token"
return request
fetcher.add_middleware(auth_middleware)
# 启用缓存
fetcher.enable_cache(ttl=3600) # 1小时缓存
# 清除缓存
fetcher.clear_cache()
