If a plain HTTP request can read it — a public page, an API, docs — usecurlor your fetch tool, and leave the browser alone.獲取公開信息不需要瀏覽器能用普通 HTTP 讀到的內(nèi)容就用 HTTP把瀏覽器留給需要點(diǎn)擊、輸入、登錄態(tài)、JS 渲染或反爬頁面的場景。Macrotrends 的所有數(shù)據(jù)端點(diǎn)都滿足這一判斷它們要么是直接返回內(nèi)嵌 JS 數(shù)組變量的 iframe PHP 頁面要么是返回 JSON 的/economic-data/API全部可以通過http_get直接訪問無需瀏覽器。本倉庫的領(lǐng)域技能文檔 scraping.md 對所有結(jié)果均已在真實(shí)站點(diǎn)上驗(yàn)證文檔標(biāo)注驗(yàn)證日期為 2026-04-18。http_get是 browser-harness 為純 HTTP 無瀏覽器場景提供的現(xiàn)成輔助函數(shù)實(shí)現(xiàn)在 src/browser_harness/helpers.pydef http_get(url, headersNone, timeout20.0): Pure HTTP — no browser.
