Macrotrends 历史金融数据提取实战基于 browser-harness 的四种无浏览器抓取模式【免费下载链接】browser-harnessBrowser Harness | Self-healing harness that enables LLMs to complete any task.项目地址: https://gitcode.com/gh_mirrors/br/browser-harnessMacrotrendshttps://www.macrotrends.net提供长期历史金融与经济图表数据覆盖股票 OHLCV 价格、市值、市盈率、营收、利润率、股息率、SP 500 指数、联邦基金利率、美债收益率、CPI、黄金价格等海量序列。本文基于本仓库agent-workspace/domain-skills/macrotrends/scraping.md的实战验证结论系统讲解在 browser-harness 项目中用纯 HTTP 方式无需启动浏览器提取这些数据的四种访问模式、完整可运行代码、字段含义与反爬注意事项。读完本文你将能够直接复制代码块抓取任意美股的历史行情与基本面数据、指数图表数据和经济指标时间序列。为什么 Macrotrends 只读任务不需要浏览器browser-harness 的核心定位是通过 CDP 直接控制真实浏览器完成交互型任务而它的 SKILL.md 明确写有一条原则A basic fetch of public information needs no browser. If a plain HTTP request can read it — a public page, an API, docs — usecurlor your fetch tool, and leave the browser alone.获取公开信息不需要浏览器能用普通 HTTP 读到的内容就用 HTTP把浏览器留给需要点击、输入、登录态、JS 渲染或反爬页面的场景。Macrotrends 的所有数据端点都满足这一判断它们要么是直接返回内嵌 JS 数组变量的 iframe PHP 页面要么是返回 JSON 的/economic-data/API全部可以通过http_get直接访问无需浏览器。本仓库的领域技能文档 scraping.md 对所有结果均已在真实站点上验证文档标注验证日期为 2026-04-18。http_get是 browser-harness 为纯 HTTP 无浏览器场景提供的现成辅助函数实现在 src/browser_harness/helpers.pydef http_get(url, headersNone, timeout20.0): Pure HTTP — no browser. Use for static pages / APIs. Wrap in ThreadPoolExecutor for bulk. When BROWSER_USE_API_KEY is set, routes through the fetch-use proxy (handles bot detection, residential proxies, retries). Falls back to local urllib otherwise. if os.environ.get(BROWSER_USE_API_KEY): try: from fetch_use import fetch_sync return fetch_sync(url, headersheaders, timeout_msint(timeout * 1000)).text except ImportError: pass import gzip h {User-Agent: Mozilla/5.0, Accept-Encoding: gzip} if headers: h.update(headers) with urllib.request.urlopen(urllib.request.Request(url, headersh), timeouttimeout) as r: data r.read() if r.headers.get(Content-Encoding) gzip: data gzip.decompress(data) return data.decode()从源码可以看到三个对本文至关重要的实现细节默认 UA 就是Mozilla/5.0——这与 Macrotrends 文档所有端点用默认 UA 即可的结论吻合自动处理 gzip 解压——/economic-data/API 返回 gzip 压缩的 JSONhttp_get已经内置解压逻辑设置了BROWSER_USE_API_KEY时自动路由到 fetch-use 代理——若你的抓取遇到反爬可在不修改代码的情况下通过代理通道获得住宅 IP、重试与机器人检测规避能力。另外领域技能中的from helpers import http_get来自 agent_helpers.py 的加载机制当BH_AGENT_WORKSPACE指向agent-workspace目录时helpers.py 的_load_agent_helpers()会把agent_helpers.py中定义的辅助函数动态注入browser_harness.helpers命名空间。领域技能文档即以此方式复用同一套 HTTP 工具。第一步根据目标数据选择访问模式Macrotrends 的数据分为四大类对应四种不同的访问模式文档给出的选择表如下表格中的延迟为文档实测值供参考目标模式延迟数据变量股票 OHLCV 价格历史直接 iframe PHP~190msdataDaily股票市值日频直接 iframe PHP~200mschartData股票基本面PE、营收、利润率直接 iframe PHP~140mschartDataSP 500 / 综合指数图表chart_iframe_comp.php~90msoriginalData经济指标利率、收益率、CPI/economic-data/JSON API~150msdata[]数组黄金、大宗商品价格两条路径均可~150msdata[]或originalData核心结论Macrotrends 只读任务绝不使用浏览器。所有端点均可用默认Mozilla/5.0UA 通过http_get访问只有个别页面偶尔返回 403 时才需要切换到 Chrome UA详见后文限流与反爬一节。Pattern 1股票价格历史OHLCV股票价格历史是最常用的数据其 iframe URL 可以直接构造无需先抓取主页面。URL 格式为https://www.macrotrends.net/production/stocks/desktop/PRODUCTION/stock_price_history.php?t{TICKER}yb{N}完整可运行代码如下import json, re from helpers import http_get def get_stock_ohlcv(ticker: str, years_back: int None) - list[dict]: Returns daily OHLCV records for any US stock. ticker: uppercase ticker symbol, e.g. AAPL, MSFT, TSLA, NVDA years_back: number of years of history (1~250 records, 15~3772 records).
