Struct FetchRequest 

Source

    pub url: String,
    pub method: Method,
    pub body: Option<String>,
    pub headers: HashMap<String, String>,
    pub render: bool,

}
Expand description

一次取页请求(URL 已是最终待请求地址或相对路径)。

Fields§

§url: String§method: Method§body: Option<String>§headers: HashMap<String, String>§render: bool

渲染型取页(render-fetcher):为真则用受控浏览器渲染本 URL(默认 headless), 跑站点自身 JS,而非 reqwest 直取。仅 [crate::fetch::browser::EscalatingFetcher] 在 browser feature 下识别;其它 fetcher 忽略本字段(退化为普通取页)。

§ready_for: Option<String>

渲染就绪等待选择器。两种用法:

  • intercept_api(方式 A):渲染后轮询该选择器出现,取渲染后 DOM 作 body;
  • intercept_api 共存(render-dual-source):拦 API 取 body 之外,等该选择器出现后 另抓渲染 DOM 入 FetchResponse::dom_html(供 via:css 规则对 DOM 求值,如分页器总页数)。
§intercept_api: Option<String>

CDP 拦截:渲染时拦截 URL 含此子串的响应体作为取页 body。可与 ready_for 共存(见上)。

§page: u32

目标页码(search-click-pagination,1 基):仅 render + intercept_api 的点击翻页路径用—— 与 page_by 共存且 > 1 时,引擎在一张活页内点 page-1 次翻到此页。其它路径忽略(默认 0)。

§page_by: Option<String>

点击驱动翻页的「下一页」CSS 选择器(search-click-pagination):URL 不认页码的 SPA (如番茄 search)靠点它递增页码。Somepage > 1 + 有 intercept_api 时启用点击翻页; 其它路径忽略(默认 None = 现状单拦截 / {{page}} URL 模板翻页)。
