转utf-8是调用api时，传的参数要utf-8嘛

CloseableHttpClient httpclient = HttpClients.createDefault();
            CloseableHttpResponse response = null;
            HttpPost request = new HttpPost("https://api.weixin.qq.com/wxa/msg_sec_check?access_token=" + jo.getString("access_token"));
            request.addHeader("Content-Type", "application/json");
            Map map = new HashMap<>();
            map.put("content",content);
            String body = com.alibaba.fastjson.JSONObject.toJSONString(map);
            request.setEntity(new StringEntity(body,ContentType.create("text/json", "UTF-8")));
            response = httpclient.execute(request);
            HttpEntity httpEntity = response.getEntity();
            String result = EntityUtils.toString(httpEntity, "UTF-8");// 转成string
            com.alibaba.fastjson.JSONObject jso = com.alibaba.fastjson.JSONObject.parseObject(result);
            String errCode = jso.getString("errcode");//错误码 0正常 87014内容含有错误信息
