java调用tushare获取免费金融数据 http接口开发

    Tushare是一个免费、开源的python财经数据接口包。主要实现对股票等金融数据从数据采集、清洗加工 到 数据存储的过程，能够为金融分析人员提供快速、整洁、和多样的便于分析的数据，为他们在数据获取方面极大地减轻工作量，使他们更加专注于策略和模型的研究与实现上。

    最近tushare推出了tushare pro ,增加对HTTP RESTful API的支持，用户可以通过标准协议，获得想要的数据，这对于其他开发者也是福音，下面只要介绍通过java开发获取tushare金融数据的方法以及碰到的一些坑，通过http 接口调用方式具体参考https://tushare.pro/document/1?doc_id=130 ，主要是通过post方式调用，需要传如下参数：

 

api_name：接口名称，比如stock_basic

token ：用户唯一标识，可通过登录pro网站获取

params：接口参数，如daily接口中start_date和end_date

fields：字段列表，用于接口获取指定的字段，以逗号分隔，如"open,high,low,close"

其中params参数，这个如果直接传字符串过去就会系统内部错误，需要通过Map对象在封装一层，我们通过httpClient接口调用回来后还需要解析，具体参考代码：

其中token需要申请注册账号

 

    public static void httpPostForStockList() {
        String url = "http://api.waditu.com";
        Map<String, Object> params = new HashMap<>(10);
        params.put("api_name", "stock_basic");
        ////token，需要申请，上面链接直达
        params.put("token", "*****************");
        //请求参数
        Map paramValue=new HashMap();
        paramValue.put("list_status","L");
        paramValue.put("exchange","SZSE");

        params.put("params", paramValue);
        params.put("fields", "ts_code,symbol,name,area,industry,fullname,enname,market,exchange,curr_type,list_status,list_date,delist_date,is_hs");
        String res = HttpClientUtils.callWebPagePost(url, JSON.toJSONString(params));

        System.out.println(res);
        Map result = (Map) JSON.parse(res);
        Map data = (Map) result.get("data");
        JSONArray arr = (JSONArray) data.get("fields");
        JSONArray dataArr = (JSONArray) data.get("items");
        for (int i = 0; i < dataArr.size(); i++) {
//			JSONObject obj=dataArr.getJSONObject(i);
            Object obj = dataArr.get(i);

            System.out.println(obj);
        }

    }

 这样我们就可以获取具体的明细数据。
