HttpWebRequest、HttpWebResponse简单Demo

HttpWebRequest 和HttpWebRespons 可以模拟浏览器的行为，对Web进行请求与提交，非常有用，我这里就把自己写的简单的例子收藏在这里

 

/// <summary>
/// 创建一个随机IP
/// </summary>
/// <returns>符合IP标准的一个IP值</returns>
private string GetIP()
{
Random random = new Random(DateTime.Now.Millisecond + DateTime.Now.Second * 1000 + DateTime.Now.Minute * 10000 + DateTime.Now.Hour * 100000);
random.Next(1, 254);
string ip = random.Next(1, 254) + "." + random.Next(1, 254) + "." + random.Next(1, 254) + "." + random.Next(1, 254);
return ip;

}
/// <summary>
/// 对一个页面进行数据发送，并返回发送后的结果
/// </summary>
protected void PostRequest()
{
//HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create("http://env.people.com.cn/GB/10725630.html");

string strIPNew = GetIP();
//内容可以使用HttpWatch 或者 FireBug 把Post的内容复制粘贴到这里
byte[] btContent = Encoding.ASCII.GetBytes("内容");

//使用Create来创建HttpWebRequest ,一般不要使用new
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create("http://XXXXX/index.aspx");;
// 如果接收方使用 string IP = Request.ServerVariables["HTTP_X_FORWARDED_FOR"] 来获取IP，就可以伪造IP地址信息
request.Headers.Add("X_FORWARDED_FOR", strIPNew);
//这里使用Post方式
request.Method = "POST";
request.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";
request.ContentType = "application/x-www-form-urlencoded;charset=gb2312";
request.ContentLength = btContent.Length;

//把要Post的内容使用流写入
using (Stream stream = request.GetRequestStream())
{
stream.Write(btContent, 0, btContent.Length);
}
//获取返回值
using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
{
using (StreamReader reader = new StreamReader(response.GetResponseStream()))
{
string strContent = reader.ReadToEnd();
Response.Write(strContent);
}
}
}
