[ASP.net教程]C#实现百度ping功能解决百度不抓取收录网站的问题


网站优化必做的事情之一,百度ping,主动推送给百度

 

文章添加时调用百度推送方法

 

    //保存    protected void btnSubmit_Click(object sender, EventArgs e)    {      if (action == DTEnums.ActionEnum.Edit.ToString()) //修改      {        ChkAdminLevel("channel_" + this.channel_name + "_list", DTEnums.ActionEnum.Edit.ToString()); //检查权限        if (!DoEdit(this.id))        {          JscriptMsg("保存过程中发生错误啦!", string.Empty);          return;        }        JscriptMsg("修改信息成功!", "article_list.aspx?channel_id=" + this.channel_id);      }      else //添加      {        ChkAdminLevel("channel_" + this.channel_name + "_list", DTEnums.ActionEnum.Add.ToString()); //检查权限        int id=DoAdd(); //此 id为添加文章返回的 此篇文章的id 需要修改添加文章的方法 返回id if (!(id>0))        {          JscriptMsg("保存过程中发生错误!", string.Empty);          return;        }        //获取频道模板名称        if (channel_id == 13 || channel_id == 16 || channel_id == 18 || channel_id == 25 || channel_id == 6)        {          string channelTemp = new BLL.channel().GetModel(this.channel_id).name.ToString();          string articleUrl = new BasePage().linkurl(channelTemp + "_show", id);          string[] url = new string[100];          url[1] = "http://www.qishunnet.com" + articleUrl;//例如生成的url如http://www.qishunnet.com/knowledge_show_132.html          string info = DTcms.Common.BaiDu.sendUrlToBaidu(url);                   JscriptMsg("添加信息成功!", "article_list.aspx?channel_id=" + this.channel_id + "&message=添加信息成功!百度推送返回信息=" + info + "url:" + url[1]);          return;        }        JscriptMsg("添加信息成功!", "article_list.aspx?channel_id=" + this.channel_id);      }    }

 

 

common类库增加百度ping方法

 

using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace DTcms.Common{  /// <summary>  /// 百度相关类  /// </summary>  public class BaiDu  {    /// <summary>    /// 推送链接至百度    /// </summary>    /// <param name="urls">链接集合</param>    /// <returns></returns>    public static string sendUrlToBaidu(string[] urls)    {      try      {        string formUrl = " http://data.zz.baidu.com/urls?site=www.qishunnet.com&token=FdSmdb3LRa4JitQp";        string formData = "";        foreach (string url in urls)        {          formData += url + "\n";        }        byte[] postData = System.Text.Encoding.UTF8.GetBytes(formData);        // 设置提交的相关参数          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;        // 提交请求数据          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;  //返回值赋值         reader.Close();        return result;      }      catch (Exception ex)      {        return ex.Message;      }    }  }}
