扒取网站内容(后台方法和前台方法的两种实现)

一.通过javascript可获取某个网站的HTML，不过只在IE下有效

function getHTTPPage(jnkcUrl) {

    var objxml = new ActiveXObject("Microsoft.XMLHTTP");

    objxml.open("GET", jnkcUrl, false);

    objxml.send();

    var sResult = objxml.responseText;

    return sResult;

}

 

二.通过C#获取

/// <summary>

/// 获取网页内容

/// </summary>

/// <param name="url">网址</param>

/// <returns>网站内容</returns>

public string GetWebSiteContent(string url)

{

    System.Net.WebClient web = new System.Net.WebClient();

    System.IO.Stream stream = web.OpenRead(url);

    System.IO.StreamReader sr = new System.IO.StreamReader(stream, System.Text.Encoding.Default);

    return sr.ReadToEnd();

}
