ASP.net百度主动推送功能实现代码

官方提供了curl、post、php、ruby的实现示例,并没有C#的官方示例。既然提供了post的方式,那么就可以用C#实现,下面是实现代码:

ASP.net百度主动推送代码范例

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);                    // 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;          }      }

调用的时候,把您的网址传入

string info = PostUrl(new string[] { "//www.jb51.net/article/1.html", "//www.jb51.net/article/2.html" });

返回的结果是{"remain":498,"success":2} 表示已经推送成功,还剩498条可以推送,本次已经推送成功2条。

另外附上可能出现的异常情况的返回码信息,供调试用:
200  无使用方式错误,需要进一步观察返回的内容是否正确
400  必选参数未提供
405  不支持的请求方式,我们只支持POST方式提交数据
411  HTTP头中缺少Content-Length字段
413  推送的数据过大,超过了10MB的限制
422  HTTP头中Content-Length声明的长度和实际发送的数据长度不一致
500  站长平台服务器内部错误
