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[] { "http://www.qdxw.net/1.html", "http://www.qdxw.net/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
