Asp.Net百度站長工具的主動推送功能

public static string PostUrl(string[] urls)
    {
        try
        {
            string formUrl = "http://data.zz.baidu.com/urls?site=www.yoursite.com&token=yourcode";
 
            string formData = "";
 
            foreach (string url in urls)
            {
                formData += url + "\n";
            }
 
            byte[] postData = System.Text.Encoding.UTF8.GetBytes(formData);
 
            // 設置提交的相關參數 
            System.Net.HttpWebRequest request = System.Net.WebRequest.Create(formUrl) as System.Net.HttpWebRequest;
            System.Text.Encoding myEncoding = System.Text.Encoding.UTF8;
            request.Method = "POST";
            request.KeepAlive = false;
            request.AllowAutoRedirect = true;
            request.ContentType = "text/plain";
            request.UserAgent = "curl/7.12.1";
            request.ContentLength = postData.Length;
 
            // 提交請求數據 
            System.IO.Stream outputStream = request.GetRequestStream();
            outputStream.Write(postData, 0, postData.Length);
            outputStream.Close();
 
            System.Net.HttpWebResponse response;
            System.IO.Stream responseStream;
            System.IO.StreamReader reader;
            string srcString;
            response = request.GetResponse() as System.Net.HttpWebResponse;
            responseStream = response.GetResponseStream();
            reader = new System.IO.StreamReader(responseStream, System.Text.Encoding.GetEncoding("UTF-8"));
            srcString = reader.ReadToEnd();
            string result = srcString;   //返回值賦值
            reader.Close();
 
            return result;
        }
        catch(Exception ex)
        {
            return ex.Message;
        }
    }
