No parameter request --> send post request

 String url = "http://www.sogou.com";
        Map<String, Object> paramMap = new HashMap<>();
        paramMap.put("query", 10086);
        // 无参GET请求
        String result = HttpUtil.get(url);
        // 带参GET请求
        String result2 = HttpUtil.get(url, paramMap);

/**
     * Send get request
     * 
     * @param urlString URL
     * @return return content, if you only check the status code, it will only return "" if it is normal, and return null if it is not normal
     */
    public static String get(String urlString) {
        return HttpRequest.get(urlString).execute().body();
    }
    
    /**
     * Send get request
     *
     * @param urlString URL
     * @param paramMap post form data
     * @return return data
     */
    public static String get(String urlString, Map<String, Object> paramMap) {
        return HttpRequest.get(urlString).form(paramMap).execute().body();
    }

Request with parameters --> send post request

HashMap<String, Object> paramMap = new HashMap<>();
paramMap.put("city", "北京");
String result= HttpUtil.post("https://www.baidu.com", paramMap);

//文件上传只需将参数中的键指定（默认file），值设为文件对象即可，对于使用者来说，文件上传与普通表单提交并无区别
paramMap.put("file", FileUtil.file("D:\\face.jpg"));
String result= HttpUtil.post("https://www.baidu.com", paramMap);

/**
     * Send post request
     * 
     * @param urlString URL
     * @param paramMap post form data
     * @return return data
     */
    public static String post(String urlString, Map<String, Object> paramMap) {         return HttpRequest.post(urlString ).form(paramMap).execute().body();     }

    /**
     * Send post request
     * 
     * @param urlString URL
     * @param params post form data
     * @return return data
     */
    public static String post(String urlString, String params) {         return HttpRequest.post(urlString).body(params ).execute().body();     }

Form form request --> send post request

String result2 = HttpRequest.post(url)
    .header(Header.USER_AGENT, "Hutool http")
    .form(paramMap)
    .execute().body();
