C#抓取網面上的html內容（JS動態生成的無法抓取）

抓取內容的代碼:

        /// </summary>
        /// <param name="url">路徑URL</param>
        /// <param name="path">存儲路徑</param>
        /// <returns></returns>
        public static string HttpDownloadFile(string url, string path)
        {
            try
            {
                // 設置參數
                HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;

                //發送請求並獲取相應回應數據
                HttpWebResponse response = request.GetResponse() as HttpWebResponse;
                //直到request.GetResponse()程序才開始向目標網頁發送Post請求
                Stream responseStream = response.GetResponseStream();

                //可以將生成的流文件直接生成字符串 SourceCode就是生成后的字符串
                //StreamReader readStream = new StreamReader(responseStream, Encoding.UTF8);
                //string SourceCode = readStream.ReadToEnd();

                //創建本地文件寫入流
                if (File.Exists(path))
                {
                    File.Delete(path);
                }
                FileStream fs = File.Create(path);
                fs.Close();
                
                Stream stream = new FileStream(path, FileMode.Create);
                byte[] bArr = new byte[1024];
                int size = responseStream.Read(bArr, 0, (int)bArr.Length);
                while (size > 0)
                {
                    stream.Write(bArr, 0, size);
                    size = responseStream.Read(bArr, 0, (int)bArr.Length);
                }
                stream.Close();
                responseStream.Close();
                return path;
            }
            catch (Exception ex)
            {

                throw ex;
            }

        }

 

調用方式：

                HttpReviceFile.HttpDownloadFile("http://localhost:811/ ", @"D:\Work\Test.xml");
