ASP.net百度主动推送功能实现代码
(编辑：jimmy 日期: 2024/5/9 浏览：3 次 )
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";
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;
}
