HttpSend网页get/post小工具发布

没事自己写的工具 

核心代码如下 主要是利用httpwebrequest抓取网站 分析数据 自动抓取网站编码。
public static string PostData(string data, string method, string postUrl) { HttpWebRequest request; HttpWebResponse response; ASCIIEncoding encoding = new ASCIIEncoding(); request = WebRequest.Create(postUrl) as HttpWebRequest; request.ProtocolVersion = HttpVersion.Version10; request.AllowAutoRedirect = true; request.KeepAlive = true; request.Headers.Add("Accept-Language", "zh-cn"); request.Accept = "image/gif, image/jpeg, image/pjpeg, image/pjpeg, application/xaml+xml, application/vnd.ms-xpsdocument, application/x-ms-xbap, application/x-ms-application, application/x-shockwave-flash, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, */*"; request.UserAgent = "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.2; Trident/4.0; .NET CLR 2.0.50727; .NET CLR 3.0.04506.30; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729; InfoPath.2; CIBA; .NET4.0C; .NET4.0E)"; request.Method = "GET"; if (method == "post") { byte[] b = encoding.GetBytes(data); request.ContentType = "application/x-www-form-urlencoded"; request.ContentLength = b.Length; request.Method = "POST"; using (Stream stream = request.GetRequestStream()) { stream.Write(b, 0, b.Length); } } string html = string.Empty; try { //获取服务器返回的资源 using (response = request.GetResponse() as HttpWebResponse) { using (StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.GetEncoding("utf-8"))) { html = reader.ReadToEnd(); Regex reg_charset = new Regex(@"charset/b/s*=/s*(?<charset>[^""]*)"); if (reg_charset.IsMatch(html)) { return PostData(data, method, postUrl, reg_charset.Match(html).Groups["charset"].Value); } else if (response.CharacterSet != string.Empty) { return PostData(data, method, postUrl, response.CharacterSet); } else return PostData(data, method, postUrl, Encoding.Default.BodyName); } } } catch (WebException wex) { WebResponse wr = wex.Response; using (Stream st = wr.GetResponseStream()) { using (StreamReader sr = new StreamReader(st, System.Text.Encoding.Default)) { html = sr.ReadToEnd(); } } } catch (Exception ex) { html ="发生异常/n/r" + ex.Message; } return html; } public static string PostData(string data, string method, string postUrl, string encode) { HttpWebRequest request; HttpWebResponse response; ASCIIEncoding encoding = new ASCIIEncoding(); request = WebRequest.Create(postUrl) as HttpWebRequest; request.ProtocolVersion = HttpVersion.Version10; request.AllowAutoRedirect = true; request.KeepAlive = true; request.Headers.Add("Accept-Language", "zh-cn"); request.Accept = "image/gif, image/jpeg, image/pjpeg, image/pjpeg, application/xaml+xml, application/vnd.ms-xpsdocument, application/x-ms-xbap, application/x-ms-application, application/x-shockwave-flash, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, */*"; request.UserAgent = "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.2; Trident/4.0; .NET CLR 2.0.50727; .NET CLR 3.0.04506.30; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729; InfoPath.2; CIBA; .NET4.0C; .NET4.0E)"; request.Method = "GET"; if (method == "post") { byte[] b = encoding.GetBytes(data); request.ContentType = "application/x-www-form-urlencoded"; request.ContentLength = b.Length; request.Method = "POST"; using (Stream stream = request.GetRequestStream()) { stream.Write(b, 0, b.Length); } } string html = string.Empty; try { //获取服务器返回的资源 using (response = request.GetResponse() as HttpWebResponse) { using (StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.GetEncoding(encode))) { html = reader.ReadToEnd(); } } } catch (WebException wex) { WebResponse wr = wex.Response; using (Stream st = wr.GetResponseStream()) { using (StreamReader sr = new StreamReader(st, System.Text.Encoding.Default)) { html = sr.ReadToEnd(); } } } catch (Exception ex) { html = "发生异常/n/r" + ex.Message; } return html; }
