如果我们把请求参数如果放在HttpPost或者HttpGet中后端该如何取参？

有两种方式

一种是从请求数据流中获取数据

 @AnonymousPostMapping("/api/router")
    public RestResult router(HttpServletRequest requestEntity) throws Exception {
        String inputStream = getInputStream(requestEntity);
        //  Object requestEntityBody = requestEntity.getBody();
        System.out.println(123);
        return RestResult.success();
    }
<!--more-->

  public static String getInputStream(HttpServletRequest request) throws Exception {
        ServletInputStream stream = null;
        BufferedReader reader = null;
        StringBuffer sb = new StringBuffer();
        try {
            stream = request.getInputStream();
            // 获取响应
            reader = new BufferedReader(new InputStreamReader(stream));
            String line;
            while ((line = reader.readLine()) != null) {
                sb.append(line);
            }
        } catch (IOException e) {
            //  logger.error(e);
        } finally {
            reader.close();
        }
        return sb.toString();
    }

方式二：
如果用的是springboot框架
可以用自带的 RequestEntity 作为实体进行接收
包是：package org.springframework.http;

 @AnonymousPostMapping("/api/router")
    public RestResult router(RequestEntity requestEntity) throws IOException {
        Object requestEntityBody = requestEntity.getBody();
        System.out.println(123);
        return RestResult.success();
    }
