简介： 远程调用-其他服务

需求

我们现在开发的APP 需要定时将APP收集的预约单发送到另一个DMS系统(服务站), 但是请求DMS系统的接口还需要先登录获取到cookie, 这个cookie是登录DMS系统后返回的Headers中的Set-Cookie的值

已知

DMS登录接口: https://dmstest.chirey.mx/api/v1/login

参数:

{

“enterpriseCode”:“15770”,

“username”:“cherysh”,

“password”:“ChErY2020”

}

同步数据接口

https://dmstest.chirey.mx/dms/afterSales/api/v1/OuterAPI/repairAppointments

编码

首先封装一个获取cookie的方法到HttpUtils中:

public String getCookie() {
        log.info("执行getCookie方法");
        String url = dmsConfig.getLoginUrl();
        HashMap<String, String> param = new HashMap<>();
        param.put("enterpriseCode",dmsConfig.getEnterpriseCode());
        param.put("username",dmsConfig.getUsername());
        param.put("password",dmsConfig.getPassword());
        String cookie = doPostJsonParamGetCookie(url, param);
//        存入redis
        redisUtil.set("cookie",cookie,20*60);
        log.info("cookie==="+cookie);
        return cookie;
    }
/**
    *   String url = "https://dmstest.chirey.mx/api/v1/login";
        HashMap<String, String> param = new HashMap<>();
        param.put("enterpriseCode","15770");
        param.put("username","cherysh");
        param.put("password","ChErY2020");
        String s = doPostJsonParamGetCookie(url, param);
    * */
    public static String doPostJsonParamGetCookie(String url, Map<String, String> jsonParam) {
        CloseableHttpClient httpClient = null;
        CloseableHttpResponse response = null;
        String result = "";
        try {
            httpClient = HttpClientBuilder.create().build();
            HttpPost httpPost = new HttpPost(url);
            httpPost.setHeader("Content-Type", "application/json");
            RequestConfig config = RequestConfig.custom().setConnectTimeout(20000).setConnectionRequestTimeout(20000).setSocketTimeout(20000).build();
            httpPost.setConfig(config);
//            传json参数
            JSONObject json = new JSONObject();
            for (Map.Entry<String, String> pa : jsonParam.entrySet()) {
                json.put(pa.getKey(),pa.getValue());
            }
            httpPost.setEntity(new StringEntity(json.toString(),"UTF-8"));
            response = httpClient.execute(httpPost);
            Header[] headers = response.getHeaders("Set-Cookie");
            for (int i = 0; i < headers.length; i++) {
                if(headers[i].toString().contains(".AspNetCore.Cookies")){
                    result=headers[i].toString().split("Set-Cookie: ")[1];
                }
            }
        } catch (Exception e) {
            logger.error("POST请求发送失败！url：{}，异常：", url, e);
        } finally {
            try {
                if (null != httpClient)
                    httpClient.close();
                if (null != response)
                    response.close();
            } catch (IOException e) {
                logger.error("链接关闭失败！url：{}，异常：", url, e);
            }
        }
        return result;
    }

然后封装一个同步预约单到dms的方法到HttpUtils中:

/**传jsonArray参数
    [
      {
        "planArriveDate": "2022-06-06T00:52:12.185Z",
        "appointNo": "55555",
        "planArriveTime": "07:00-08:00",
        "dealerCode": "18888",
        "repairType": 1,
        "isWx": "3",
        "cellPhoneNumber": "13855222215",
        "customerName": "王三",
        "licensePlate": "皖B88888",
        "status": 1,
        "vinCode": "LVVDC21B2ND033754"
      }
    ]
    具体写法：
        List<AppointBillVO> allNewBills = appointBillService.getAllNewBillListForDMS();
//        从redis获取cookie
        String cookie = (String) redisUtil.get("cookie");
        if(StringUtils.isEmpty(cookie)){
             cookie = httpUtils.getCookie();
        }
        String url = "https://dmstest.chirey.mx/dms/afterSales/api/v1/OuterAPI/repairAppointments";
        JSONArray jsonArray = JSONArray.parseArray(JSON.toJSONString(allNewBills));
        String result = HttpUtils.doPostJsonObjectParam(url, jsonArray, cookie);
    * */
    public static String doPostJsonObjectParam(String url, JSONArray jsonArray, String cookie) {
        CloseableHttpClient httpClient = null;
        CloseableHttpResponse response = null;
        String result = "";
        try {
            httpClient = HttpClientBuilder.create().build();
            HttpPost httpPost = new HttpPost(url);
            httpPost.setHeader("Cookie", cookie);
            httpPost.setHeader("Content-Type", "application/json");
            RequestConfig config = RequestConfig.custom().setConnectTimeout(20000).setConnectionRequestTimeout(20000).setSocketTimeout(20000).build();
            httpPost.setConfig(config);
//            传json参数
            httpPost.setEntity(new StringEntity(jsonArray.toString(),"UTF-8"));
            response = httpClient.execute(httpPost);
            result = EntityUtils.toString(response.getEntity());
        } catch (Exception e) {
            logger.error("POST请求发送失败！url：{}，异常：", url, e);
        } finally {
            try {
                if (null != httpClient)
                    httpClient.close();
                if (null != response)
                    response.close();
            } catch (IOException e) {
                logger.error("链接关闭失败！url：{}，异常：", url, e);
            }
        }
        return result;
    }

最后写一个定时任务接口:

//    @Scheduled(cron = "0 0/10 * * * ?") // 使用xxl-job控制定时任务
    @RequiredLog("APP-DMS 同步所有新建预约记录")
    @ApiOperation(value = "APP-DMS 同步所有新建预约记录")
    @RequestMapping(value = {"getAllNewBillListForDMS"}, method = RequestMethod.POST)
    public RespMessage<List<AppointBillVO>> getAllNewBillListForDMS() {
        log.info("APP-DMS 同步所有新建预约记录 定时任务调用了！！！");
        // 查询所有新建预约单
        List<AppointBillVO> allNewBills = appointBillService.getAllNewBillListForDMS();
        log.info("查询到的所有新建预约单==="+allNewBills.toString());
//        从redis获取cookie
        String cookie = (String) redisUtil.get("cookie");
        log.info("从Redis获取到的cookie是==="+cookie);
        if(StringUtils.isEmpty(cookie)){
             cookie = httpUtils.getCookie();
        }
        log.info("cookie==="+cookie);
        if(!CollectionUtils.isEmpty(allNewBills)){
            String url = dmsConfig.getAppointmentsUrl();
            JSONArray jsonArray = JSONArray.parseArray(JSON.toJSONString(allNewBills));
            log.info("APP-DMS 同步的所有预约记录===>"+jsonArray.toJSONString());
            String result = HttpUtils.doPostJsonObjectParam(url, jsonArray, cookie);
            if(result.contains("成功")){
                // 将这些预约单状态修改为已发送
                if(!CollectionUtils.isEmpty(allNewBills) && allNewBills.size() > 0){
                    ArrayList<String> appointNos = new ArrayList<>();
                    allNewBills.forEach(e ->{
                        appointNos.add(e.getAppointNo());
                    });
                    appointBillService.updateStatusByNos(appointNos);
                }
                return RespMessage.ok(allNewBills);
            }
        }
        return RespMessage.errorWithMsg("同步失败");
    }
