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:

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.zzvips.com/article/1.html", "//www.zzvips.com/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

//点击按钮触发

   {
     string info = PostUrl(new string[] { "//www.zzvips.com/", "//www.zzvips.com/article/3.html" });
     this.Label1.Text= info;
