我阅读了许多主题如何从网站上获取数据等，但我无法找到解决问题的方法。
所以，我试图从这个表中获取数据： http://www.opole.pios.gov.pl:81/dane-pomiarowe/automatyczne/stacja/118/parametry/461/dzienny/07.02.2017
但是每个方法都只给我这样的html代码：

我无法找到我想要的东西。
答案 0 :(得分：-1)
我相信该表的数据实际上来自JSON服务。
const {nodeInterface, nodeField} = nodeDefinitions(
(globalId, context) => {
const {type, id} = fromGlobalId(globalId);
if (type === 'bar') {
// get Bar with id==id if context.user has access
return getBar(context.user, id);
} else {
return null;
}
},
(obj) => {
// return the object type
}
);

参数，它实际上也是JSON：
query因此，在较高级别，您可以为此JSON创建{"measType":"Auto","viewType":"Station","dateRange":"Day","date":"07.02.2017","viewTypeEntityId":"118","channels":[461]}
并解析结果。上传数据的好方法是使用WebClient.UploadString。
使用JSON.Net以JToken.Parse为例解析结果，您可以访问要查找的元素。
POST结果如下：
string url = "http://www.opole.pios.gov.pl:81/dane-pomiarowe/pobierz";
string data = "query=" + HttpUtility.UrlEncode("{\"measType\":\"Auto\",\"viewType\":\"Station\",\"dateRange\":\"Day\",\"date\":\"07.02.2017\",\"viewTypeEntityId\":\"118\",\"channels\":[461]}");
System.Net.WebClient wc = new System.Net.WebClient();
wc.Headers[System.Net.HttpRequestHeader.ContentType] = "application/x-www-form-urlencoded; charset=UTF-8";
string response = wc.UploadString(url, data);
Newtonsoft.Json.Linq.JToken jsonResponse = Newtonsoft.Json.Linq.JToken.Parse(response);
DateTime epoch = new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc);
foreach (var entry in jsonResponse["data"]["series"][0]["data"])
{
Response.Write("UTC Time: " + epoch.AddSeconds((int)entry[0]) + ", Value: " + entry[1] + "<br>");
}
