使用 C# 采集网站返回的json数据

1、雪球网数据接口使用说明：
https://xueqiu.com/stock/forchartk/stocklist.json?symbol=代码&period=1day&type=复权还是不复权&begin=开始时间时间戳&end=结束时间时间戳&_=结束时间时间戳
地址参数：上海股票在编号前加SH，深圳股票，在编号前加SZ，period代表的时间间隔，复权不复权使用after和before表示，开始时间和结束时间要用时间戳表示。
注意访问下面的网址前要先点击https://xueqiu.com/，进入一次官网，然后在http头中才能记录你的数据，然后才能通过下面的网址获取数据。
2、网址例子、https://xueqiu.com/stock/forchartk/stocklist.json?symbol=SH600756&period=1day&type=before&begin=1478620800000&end=1510126200000&_=1510126200000
3、要求：使用C#完成获取雪球网json数据，需要给出测试结果，demo给出的结果只要symbol（股票代码）volume、open即可

            {
                Console.WriteLine("\t" + result.chartlist[i].volume + " " + result.chartlist[i].open);
            }
            Console.WriteLine("\t" + "...");

作为演示，这里cookie获取我是写死的，你要看到运行效果，需要自己去抓cookie，方法如下：

用程序获取cookie这个你可以自己搜索下，如果搞不定的话，采纳本回答，我可以详细写给你。另外还可以给你写一个时间/时间戳数字的转换的代码。

时间戳的方便的话也发一下吧，谢谢

不好意思，才看到

        {
            HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create("https://xueqiu.com/");

            Console.WriteLine(result.stock.symbol);
            for (int i = 0; i < 20; i++)
            {
                Console.WriteLine("\t" + result.chartlist[i].volume + " " + result.chartlist[i].open);
            }
            Console.WriteLine("\t" + "...");
        }
    }
}

另外给你一个计算时间戳的代码：
static long gettimestamp(DateTime dt)
{
var span = new TimeSpan(dt.Ticks - new DateTime(1970, 1, 1).Ticks);
return (long)span.TotalMilliseconds;
}
使用例子：
Console.WriteLine(gettimestamp(DateTime.Now));
结果
1532593564270

你可以代入你的begin end的参数
begin=1478620800000&end=1510126200000
