Java Http POST/GET 情求

POST:

    //返回体
    public static final String RESPONCE_BODY = "responceBody";

    //URL
    public static final String FINAL_URL = "url";

    //发送信息
    public static final String SEND_BODY = "sendBody";

/**
     * post请求
     *
     * @param url         url地址
     * @param entityParam 参数
     * @return
     */
    public static HashMap post(String url, Entity entityParam) {
        HashMap resultMap = new HashMap<String, String>();
        String resultStr = "";
        log.info("执行信息体|url:" + url + " ||json:" + entityParam);
        try (CloseableHttpClient httpClient = HttpClients.createDefault()) {
            url = URLDecoder.decode(url, "UTF-8");
            HttpPost method = new HttpPost(url);
            if (null != entityParam) {
                StringEntity entity = new StringEntity(entityParam.toJson(), "UTF-8");
                entity.setContentType("application/json;charset=UTF-8");
                method.setEntity(entity);
            }
            HttpResponse result = httpClient.execute(method);
            log.info("返回码：" + result.getStatusLine().getStatusCode());
            resultStr = EntityUtils.toString(result.getEntity());
            log.info("返回内容：" + resultStr);
        } catch (Exception e) {
            log.error("错误信息:", e);
        }
        resultMap.put(SEND_BODY, entityParam.toJson());
        resultMap.put(RESPONCE_BODY, resultStr);
        resultMap.put(FINAL_URL, url);
        return resultMap;
    }

GET 情求

    /**
     * get请求
     *
     * @param url
     */
    public static CloseableHttpResponse getRequest(String url, Map<String, String> headMap) {
        CloseableHttpResponse response = null;
        try {
            HttpGet httpGet = new HttpGet(toUTF_8(url, "utf-8"));
            if (!CollectionUtils.isEmpty(headMap)) {
                headMap.forEach((k, v) -> httpGet.setHeader(k, v));
            }
            response = httpClient.execute(httpGet);
            response.close();
        } catch (Exception e) {
            log.info("get请求出错：", e);
        }
        return response;
    }
