java 通用 post 请求

java 实现 Http的 Post 请求  用 Json 为参数

调用：

//_http_url_cdr为
//"http://10.10.10.243:15642/call/upload/ctiCdrUpload"

//eventJson 为
//{"callid":"1635822668.528","callto":"6700(1008)","pincode":"","srctrunkname":"MNWG","status":"ANSWERED"}
                 
//Http请求 
httpPost(_http_url_cdr,eventJson);

参数手动生成函数

public static void httpPost(String url,String eventJson){
        //发送请求的URL
        //String url = "http://10.10.10.243:15642/call/upload/ctiCdrUpload";
        logger.debug("httpPost() 准备HttpPost请求! " + url + " " + "");

        //请求内容  示例
        /* 
        {
            "event": "NewCdr",
                "callid": "1627349862.433",
                "timestart": "2021-07-27 09:37:42",
                "callfrom": "1008",
                "callto": "1009"
        }*/
        //请求内容  示例 手动生成
        /*
        JSONObject jsonParam = new JSONObject();
        jsonParam.put("event","NewCdr");
        jsonParam.put("callid","1627349862.433");
        jsonParam.put("timestart","2021-07-27 09:37:42");
        jsonParam.put("callfrom","1008");
        jsonParam.put("callto","1009");
        jsonParam.put("callduraction","16");
        jsonParam.put("talkduraction","11");
        jsonParam.put("srctrunkname","");
        jsonParam.put("dsttrcunkname","");
         */

        //将字符串转化成JSONObject
        JSONObject jsonParam= JSON.parseObject(eventJson);

        logger.debug("httpPost() HttpPost请求参数: " + jsonParam.toJSONString() + " " + "");
        //发送Http Post请求
        JSONObject jsonResult=httpPostSendRequest(url,jsonParam);

        logger.debug("httpPost() HttpPost请求结果: " + jsonResult.toString() + " " + "");
    }

java通用 Http Post 请求 方法

    public static JSONObject httpPostSendRequest(String url,JSONObject param){
        //定义接收数据
        JSONObject result = new JSONObject();
        HttpPost httpPost = new HttpPost(url);
        CloseableHttpClient client = HttpClients.createDefault();
        //请求参数转JOSN字符串
        StringEntity entity = new StringEntity(param.toJSONString(), "UTF-8");
        entity.setContentEncoding("UTF-8");
        entity.setContentType("application/json");
        httpPost.setEntity(entity);
        try {
            HttpResponse response = client.execute(httpPost);
            if (response.getStatusLine().getStatusCode() == 200) {
                result = JSON.parseObject(EntityUtils.toString(response.getEntity(), "UTF-8"));
            }
        } catch (Exception e) {
            e.printStackTrace();
            //result.put("error", "连接错误！");
            logger.error("httpPostSendRequest() HttpPost " + "=======连接错误=======");
        }
        return result;
    }
