**一、前端传输参数**  
参数格式如下：

{
                "bk_app_code": "service-desk",
                "bk_app_secret": "2b502835-65f1",
                "bk_username": "BPM",
                "flow_no": "papersheet",
                "action_type": "usb_enable",
                "callback_url": null,
                "action_data": {
                    "ad_account": "20021339",
                    "hostname": "DW7CNECZ89",
                    "is_laptop": "false",
                    "usb_group": "03_Print",
                    "usb_group_name": "打印",
                    "url": "papersheet",
                    "start_date": "2021-02-07"  
                               }
            }

利用ajax调用后台接口

$.ajax({ 
                url: '${pageContext.request.contextPath}/IT00022Controller/offLineOpen.action',
                type: 'post',
                async : false,
                data: { 
                    url: "http://test.aact.com:80/api/c/self-service-api/auto_action_test/",
                    data: JSON.stringify(data)
                },
                dataType : 'json',
                success : function(result) { 
                    $.messager.progress('close');
                    if(result.result == "true"){ 
                        alert("开通成功！！！");
                      	resetData();
                    }else{ 
                        alert("开通失败！！！");
                    }
                }
            });

**二、后端代码**

@RequestMapping("/offLineOpen")
        @ResponseBody
        public Map<String,Object> offLineOpen(String url,String data){ 
            JSONObject jsonObject = JSON.parseObject(data);
            String param = " {\n" +
                    " \"bk_app_code\": \"service-desk\",\n" +
                    " \"bk_app_secret\": \"2b502835-65f1\",\n" +
                    " \"bk_username\": \"BPM\",\n" +
                    " \"flow_no\": \"papersheet\",\n" +
                    " \"action_type\": \"usb_enable\",\n" +
                    " \"callback_url\": null,\n" +
                    " \"action_data\": {\n" +
                    " \"ad_account\": \""+jsonObject.get("ad_account")+"\",\n" +
                    " \"hostname\": \""+jsonObject.get("hostname")+"\",\n" +
                    " \"is_laptop\": \""+jsonObject.get("is_laptop")+"\",\n" +
                    " \"usb_group\": \""+jsonObject.get("usb_group")+"\",\n" +
                    " \"usb_group_name\": \""+jsonObject.get("usb_group_name")+"\",\n" +
                    " \"url\": \"papersheet\",\n" +
                    " \"end_date\": \""+jsonObject.get("end_date")+"\"" +
                    " }\n" +
                    " }";
            String result = it22Service.doPost(url,param);
            JSONObject resultMap = JSON.parseObject(result);
            if(resultMap.getString("result").equals("false")) { 
            	jsonObject.put("result",resultMap.getString("result")+";"+resultMap.getString("message"));
            }else { 
            	jsonObject.put("result",resultMap.getString("result"));
            }
            iT00022Service.insertOffLineDate(jsonObject);
            return jsonObject;
        }

public String doPost(String strURL, String params) { 
            BufferedReader reader = null;
            try { 
                URL url = new URL(strURL);// 创建连接
                HttpURLConnection connection = (HttpURLConnection) url.openConnection();
                connection.setDoOutput(true);
                connection.setDoInput(true);
                connection.setUseCaches(false);
                connection.setInstanceFollowRedirects(true);
                connection.setRequestMethod("POST"); // 设置请求方式
                // connection.setRequestProperty("Accept", "application/json"); // 设置接收数据的格式
                connection.setRequestProperty("Content-Type", "application/json"); // 设置发送数据的格式
                connection.connect();
                //一定要用BufferedReader 来接收响应， 使用字节来接收响应的方法是接收不到内容的
                OutputStreamWriter out = new OutputStreamWriter(connection.getOutputStream(), "UTF-8"); // utf-8编码
                out.append(params);
                out.flush();
                out.close();
                // 读取响应
                reader = new BufferedReader(new InputStreamReader(connection.getInputStream(), "UTF-8"));
                String line;
                String res = "";
                while ((line = reader.readLine()) != null) { 
                    res += line;
                }
                reader.close();
                return res;
            } catch (IOException e) { 
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            return "error"; // 自定义错误信息
        }
