ASP.net百度主动推送功能实现
百度站长提供了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.laike.net/article/1.html", "//www.laike.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.1fd.net/", "//www.1fd.net/article/3.html" }); this.Label1.Text= info; }
希望能帮到大家。
