Question

我有一个URL，它返回数据数组。例如，如果我有网址http://test.com?id=1，则会返回3,5,6,7等值...

有什么方法可以处理这个URL并获取返回的值而无需去浏览器（处理应用程序中的url）？

由于

Answer 1

非常简单：

using System.Net;

...

var response = new WebClient().DownloadString("http://test.com?id=1");

Answer 2

string urlAddress = "YOUR URL";
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(urlAddress);
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
if (response.StatusCode == HttpStatusCode.OK)
{
  Stream receiveStream = response.GetResponseStream();
  StreamReader readStream = null;
  if (response.CharacterSet == null)
    readStream = new StreamReader(receiveStream);
  else
    readStream = new StreamReader(receiveStream, Encoding.GetEncoding(response.CharacterSet));
  string data = readStream.ReadToEnd();
  response.Close();
  readStream.Close();
}

这应该可以解决问题。

它返回主页的html源代码并将其填入string data。

您现在可以使用该字符串。

这是一个我经常用于类似目的的简单函数（VB.NET）：

Public Shared Function GetWebData(url As String) As String
    Try
        Dim request As WebRequest = WebRequest.Create(url)
        Dim response As HttpWebResponse = CType(request.GetResponse(), HttpWebResponse)
        Dim dataStream As Stream = response.GetResponseStream()
        Dim readStream As StreamReader = New StreamReader(dataStream)
        Dim data = readStream.ReadToEnd()
        readStream.Close()
        dataStream.Close()
        response.Close()
        Return data
    Catch ex As Exception
        Return ""
    End Try
End Function

要使用它，请将URL传递给它，它将返回URL的内容。
