Process URL and Get data
提问by huMpty duMpty
I have a URLwhich returns array of data.
For example if I have the URL http://test.com?id=1it will return values like 3,5,6,7etc…
我有一个URL返回数据数组。例如，如果我有 URL http://test.com?id=1，它将返回诸如3,5,6,7等的值……
Is there any way that I can process this URL and get the returned values without going to browser (to process the url within the application)?
有什么方法可以处理此 URL 并获取返回值而无需访问浏览器（以处理应用程序中的 url）？
Thanks
谢谢

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();
}
This should do the trick.
这应该可以解决问题。
It returns the html source code of the homepage and fills it into the string data.
它返回主页的 html 源代码并将其填充到string data.
You can use that string now.
您现在可以使用该字符串。

This is a simple function I constantly use for similar purposes (VB.NET):
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
To use it, pass it the URL and it will return the contents of the URL.
要使用它，请将 URL 传递给它，它将返回 URL 的内容。
