Java – Hutool 获取 HttpRequest：Header、Body、ParamMap 等利器

以前用过手撕 HttpRequest 获取 Body、Params、Header 等 API 的时候，那叫一个复杂，自从用了 Hutool 神器后，发现如此的轻巧​​​​​​​

// 获取请求头
HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();
Map<String, String> requestHeaderMap = ServletUtil.getHeaderMap(request);

// 获取请求体
Map<String, Object> requestParamMap = new LinkedHashMap<>();
String body = ServletUtil.getBody(request);
Map<String, String> params = ServletUtil.getParamMap(request);
