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

我实际应用代码

 //点击按钮触发
    protected void Button1_Click(object sender, EventArgs e)
    {
      string info = PostUrl(new string[] { "//www.jb51.net/", "//www.jb51.net/article/3.html" });
      this.Label1.Text= info;
    }
