Java 透传

这次任务是接口透传

1 首先外部有一个提供一个完整的接口，可以调的通。

测试时候可以postman调用。外部系统得要提供完成API文档。以助于更好的对接。

例如确定请求方式，入参的格式。

2 

将外部接口配置

 3 调用

 这里用的是post请求，返回数据的json格式，已经封装成result.

@Override
    public Result storeInforMation(StoreInformation storeInformation) throws Exception {
        Result result =new Result();
        List<StoreListinfo> storeListinfo = new ArrayList<>();
        StoreListinfoBound storeListinfoBound=new StoreListinfoBound();
        Map<String, Object> map = new HashMap<>();
        map.put("code", storeInformation.getCode());
        map.put("provinceId", storeInformation.getProvinceId());
        map.put("cityId", storeInformation.getCityId());
        map.put("areaId", storeInformation.getAreaId());
        map.put("agentName", storeInformation.getAgentName());
        String response = HttpClientUtil.httpPostRequest(wmsZngUrl,JSON.toJSONString(map));
        log.info("wmsZngUrl={} and  response is: {}",wmsZngUrl,response);
         com.jiutong.entity.flagshipStore.Result result1 = JSONObject.parseObject(response, com.jiutong.entity.flagshipStore.Result.class);
         if( result1.getCode()==-1){
              result.setResultCode(new ResultCode(-1,"请求失败"));
         }else{
              JSONObject data=JSONObject.parseObject(String.valueOf(result1.getData()));
             if(data==null){
                 result.setResultCode(new ResultCode(0,"请求成功，暂无数据"));
             }else{
                 Object storeList = Optional.ofNullable(getFromJson(data, "storeList")).orElse("");
                 Object bound = Optional.ofNullable(getFromJson(data, "bound")).orElse("");
                 com.alibaba.fastjson.JSONArray jsonArray= JSON.parseArray(JSONUtil.toJson(storeList));
                 for(int i=0;i<jsonArray.size();i++){
                    JSONObject jsonObject = jsonArray.getJSONObject(i);
                     String address = Optional.ofNullable(getFromJson(jsonObject,"address")).orElse("").toString();
                     String storeName = Optional.ofNullable(getFromJson(jsonObject,"storeName")).orElse("").toString();
                     Integer  id = (Integer) Optional.ofNullable(getFromJson(jsonObject,"id")).orElse("");
                     StoreListinfo storeListinfo1 = new StoreListinfo();
                     storeListinfo1.setId(id);
                     storeListinfo1.setStoreName(storeName);
                     storeListinfo1.setAddress(address);
                     storeListinfo.add(storeListinfo1);
                 }
                 storeListinfoBound.setBound(bound.toString());
                 storeListinfoBound.setStoreListinfo(storeListinfo);
                 result.setData(storeListinfoBound);
             }
         }
       return  result;
    }

    private Object getFromJson(JSONObject jsonObject, String key){
        if(jsonObject.containsKey(key)){
            return jsonObject.get(key);
        }
        return null;
    }

4

 JSON.parseObject（String str）是将str转化为相应的JSONObject对象

5 HttpClientUtil.httpPostRequest方法

 

任务也是比较简单的，在联调的时候，花的时间比较多，两者很多事情没有说清楚，需要一个详细的API文档。
