Day16 高级玩法-拦截并获取网络请求

2026/8/3 17:19:39

一、说明

有的时候登录的时候会获取验证码，有些情况下验证码是通过接口的上下请求rsa 加解密后可以获取，这个时候我们可以通过的getResponseByUrlPattern 方法，抓取对应的请求，方法如下

/** * 拦截操作后的数据 * @param urlPattern URL 包含的字符串（非正则，内部用 contains 匹配） * @param method 触发动作方法名（如 click、enter、tab 等无参动作），作为 waitForResponse 的触发 Runnable； * 为 null 或空时表示动作已在步骤中执行，仅等待对应响应 * @return */ public String getResponseByUrlPattern( String urlPattern,String method) { Runnable runnable1 = () -> { if (method == null || method.isEmpty()) { return; } doAction(method); }; // 1. 定义你想要捕获的接口特征 (Predicate) // 比如：URL 包含 "community-search-pc" 且状态码是 200 Predicate<Response> searchResponsePredicate = response -> response.url().contains(urlPattern) && response.status() == 200; // 这里的页面点击会触发一个网络接口请求 return page.waitForResponse(searchResponsePredicate, runnable1).text(); }

小工具，可以步骤定义中，点击新增，动作方法选择 getResponseByUrlPattern 选项。如下图

getResponseByUrlPattern使用说明

拦截并获取网络响应 | 参数:1~2个(用||分隔) | URL匹配模式:字符串, 触发动作(可选):无参动作方法名(如click/enter/tab，为空则仅等待响应)

二、例子

我们有这样一个场景

登录平台的时候，前端会向后端请求一个

http://localhost/dev-api/captchaImage

获取验证码的接口，为了方便测试，我把验证码的答案也放在返回里面了。返回结果如下：
