记录一下用httpUtil工具类的post请求带头部参数

缺乏、安全感 2023-09-30 09:53 3阅读 0赞

本来网上有很多HttpUtil工具类封装，里面封装了各种doget/dopost

本身自己项目之前也有人用过，但是最近对接一个第三方短信平台，按照他们的文档需要传参头部参数，但是不知道为什么用现有的post请求没法修改头部参数，所以自己写一个post请求吧

//短信平台要求固定的头部参数格式
    Map<String, String> header = Maps.newHashMap();
                header.put("Accept", "application/json;charset=utf-8");
                header.put("Content-Type", "application/json;charset=utf-8");
                //请求参数的账号密码以及加密
                LinkedHashMap map = new LinkedHashMap();
                map.put("userName", name);
                String result = HttpUtil.doPostJson("url", header, JsonHelper.objectToJson(map));

public static String doPostJson(String url,Map<String, String> headerMap, String json) {
            // 创建Httpclient对象
            CloseableHttpClient httpClient = HttpClients.createDefault();
            CloseableHttpResponse response = null;
            String resultString = "";
            try {
                // 创建Http Post请求
                HttpPost httpPost = new HttpPost(url);
                if (headerMap != null) {
                    Iterator headerIterator = headerMap.entrySet().iterator();          //循环增加header
                    while(headerIterator.hasNext()){
                        Entry<String,String> elem = (Entry<String, String>) headerIterator.next();
                        httpPost.addHeader(elem.getKey(),elem.getValue());
                    }
                }
                // 创建请求内容
                StringEntity entity = new StringEntity(json, ContentType.APPLICATION_JSON);
                httpPost.setEntity(entity);
                // 执行http请求
                response = httpClient.execute(httpPost);
                resultString = EntityUtils.toString(response.getEntity(), "UTF8");
            } catch (Exception e) {
                e.printStackTrace();
            } finally {
                try {
                    response.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
            return resultString;
        }
