公司项目（2）：HTTP请求工具类

一：POST

 public static JSONObject post(String url, JSONObject jsonObj, String token) throws Exception {

        HttpClientBuilder httpClientBuilder = HttpClientBuilder.create();
        CloseableHttpClient closeableHttpClient = httpClientBuilder.build();

        JSONObject result = new JSONObject();
        int statusCode = 0;
        String content = null;
        try {
            HttpPost post = new HttpPost(url);

            if (null != jsonObj) {
                // 构建消息实体
                StringEntity entity = new StringEntity(jsonObj.toString(), Charset.forName("UTF-8"));
                entity.setContentEncoding("UTF-8");
                // 发送Json格式的数据请求
                entity.setContentType("application/json");
                // 参数置入
                post.setEntity(entity);
            }

            if (null != token && !"".equals(token)) {
                post.setHeader("Authorization", token);
            }

            CloseableHttpResponse response = closeableHttpClient.execute(post);

            // 检验返回码
            statusCode = response.getStatusLine().getStatusCode();
            HttpEntity entity = response.getEntity();
            content = EntityUtils.toString(entity, "utf-8");
            if (statusCode == HttpStatus.SC_OK || statusCode == HttpStatus.SC_CREATED) {               
                result.put("code", statusCode);
                result.put("content", content);
                response.close();
            } else {         
                //取出错误信息message
                JSONObject jsonObject = JSON.parseObject(content);
                String message = jsonObject.getJSONObject("errors").getString("message");
                //logger.info("message is " + message);
                result.put("code", statusCode);
                result.put("content", message);
                response.close();
            }
        } catch (Exception e) {
            e.printStackTrace();
        }

        try {
            closeableHttpClient.close();  //关闭连接、释放资源
        } catch (IOException e) {
            e.printStackTrace();
        }
        return result;
    }

二：PUT

 public static boolean put(String url, JSONObject jsonObj, String token) {

        HttpClientBuilder httpClientBuilder = HttpClientBuilder.create();
        CloseableHttpClient closeableHttpClient = httpClientBuilder.build();

        boolean returnValue = false;

        HttpPut httpput = new HttpPut(url);

        //设置header
        httpput.setHeader("Content-type", "application/json");

        if (null != token && !"".equals(token)) {
            httpput.setHeader("Authorization", token);
        }

        //组织请求参数
        StringEntity stringEntity = new StringEntity(jsonObj.toString(), "utf-8");
        httpput.setEntity(stringEntity);
        String content = null;
        CloseableHttpResponse httpResponse = null;
        try {
            //响应信息
            httpResponse = closeableHttpClient.execute(httpput);
            HttpEntity entity = httpResponse.getEntity();
            content = EntityUtils.toString(entity, "utf-8");
            // 检验返回码
            int statusCode = httpResponse.getStatusLine().getStatusCode();
            if (statusCode == HttpStatus.SC_OK || statusCode == HttpStatus.SC_CREATED) {
                returnValue = true;
            }
            httpResponse.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
        try {
            closeableHttpClient.close();  //关闭连接、释放资源
        } catch (IOException e) {
            e.printStackTrace();
        }
        return returnValue;
    }
