网站自动化录入小工具

网站自动化录入小工具

 公司要录入一大批信息到OA 系统，破网站也是年久失修没有批量导入操作。
 只能人手工一条条对着EXCEL导入，这啥时候到头啊，要是用按键精灵的话，
 电脑就一直不能关，不能动，还有一大堆活呢，索性写个小工具。

第一步：解析Excle 转化成实体类

      为了保证结果没有错误，可以自我检查，可以把数据放到一个table里面；
   下面是解析excel的代码*：（**注意下xls 和 xlsx 两种格式，引用NPOI即可**）
   转化实体类的就不写了，就是遍历返回List  然后给实体赋值）

      /// 

        /// Excel转化到DataTable
        /// 
        /// 文件路径
        /// true:成功 false:失败
        private List ExcelToDataTable(string strFileName)
        {
            List list = new List();
            DataTable dt = new DataTable();
            HSSFWorkbook hssfworkbook = null;
            XSSFWorkbook xssfworkbook = null;
            string fileExt = Path.GetExtension(strFileName);//获取文件的后缀名
            using (FileStream file = new FileStream(strFileName, FileMode.Open, FileAccess.Read))
            {
                if (fileExt == ".xls")
                    hssfworkbook = new HSSFWorkbook(file);
                else if (fileExt == ".xlsx")
                    xssfworkbook = new XSSFWorkbook(file);//初始化太慢了，不知道这是什么bug
            }
            if (hssfworkbook != null)
            {
                list.Clear();
                int count = hssfworkbook.NumberOfSheets; //获取所有SheetName
                for (int sheetnum = 0; sheetnum < count;sheetnum++ )
                {
                    HSSFSheet sheet = (HSSFSheet)hssfworkbook.GetSheetAt(sheetnum);
                    if (sheet != null)
                    {
                        System.Collections.IEnumerator rows = sheet.GetRowEnumerator();
                        HSSFRow headerRow = (HSSFRow)sheet.GetRow(0);
                        int cellCount = headerRow.LastCellNum;
                        for (int j = 0; j < cellCount; j++)
                        {
                            HSSFCell cell = (HSSFCell)headerRow.GetCell(j);
                            dt.Columns.Add(cell.ToString());
                        }
                        for (int i = (sheet.FirstRowNum + 1); i <= sheet.LastRowNum; i++)
                        {
                            HSSFRow row = (HSSFRow)sheet.GetRow(i);
                            DataRow dataRow = dt.NewRow();
                            for (int j = row.FirstCellNum; j < cellCount; j++)
                            {
                                if (row.GetCell(j) != null)
                                    list.Add(row.GetCell(j).ToString());
                                dataRow[j] = row.GetCell(j).ToString();
                            }
                            dt.Rows.Add(dataRow);
                        }
                        dataGridView1.DataSource = dt;
                       
                    }
                }          
            }
            else if (xssfworkbook != null)
            {
                int isFrist = 0;
                int cellCount = 0;
                int count1 = xssfworkbook.NumberOfSheets; //获取所有SheetName
                  for (int sheetnum = 0; sheetnum < count1; sheetnum++) 
                  {
                      XSSFSheet xSheet = (XSSFSheet)xssfworkbook.GetSheetAt(sheetnum);
                      if (xSheet != null)
                      {
                          if (isFrist==0) 
                          {
                              System.Collections.IEnumerator rows = xSheet.GetRowEnumerator();
                              XSSFRow headerRow = (XSSFRow)xSheet.GetRow(0);
                               cellCount = headerRow.LastCellNum;
                              for (int j = 0; j < cellCount; j++)
                              {
                                  XSSFCell cell = (XSSFCell)headerRow.GetCell(j);
                                  dt.Columns.Add(cell.ToString());
                              }
                              isFrist++;
                          }                        
                          for (int i = (xSheet.FirstRowNum + 1); i <= xSheet.LastRowNum; i++)
                          {
                              XSSFRow row = (XSSFRow)xSheet.GetRow(i);
                              DataRow dataRow = dt.NewRow();
                              for (int j = row.FirstCellNum; j < cellCount; j++)
                              {
                                  if (row.GetCell(j) != null)
                                      list.Add(row.GetCell(j).ToString());
                                      dataRow[j] = row.GetCell(j).ToString();
                              }
                             dt.Rows.Add(dataRow);
                          }
                         dataGridView1.DataSource = dt;
                         
                      }
                  }             
            }
            return list;
        }

第二步：开始使用抓包工具，我用的wireshark，设置好ip和通讯方式以及端口，把你想要自动化的步骤操作一次，记录下包内容然后开始拼凑string

     eg:登录时候，我抓到的包 j_username=123   j_password=123 
     那我就拼好String 发送到访问连接就好了；

StringBuilder sb = new StringBuilder();
            sb.AppendFormat("j_username={0}&j_password={1}", name, pwd);

第三步：发包（最后根据返回信息判断是否成功）

        /// 
        ///  目标地址
        /// 发送信息
        /// 返回信息
        public string PostLogin(string referUrl, string data)
        {
            CookieContainer cookie = new CookieContainer();
            string result = "";
            try
            {
                //命名空间System.Net下的HttpWebRequest类
                HttpWebRequest request = (HttpWebRequest)WebRequest.Create(referUrl);
                //参照浏览器的请求报文 封装需要的参数 这里参照ie9
                //浏览器可接受的MIME类型
                request.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8";
                //包含一个URL，用户从该URL代表的页面出发访问当前请求的页面
                request.Referer = referUrl;
                //浏览器类型，如果Servlet返回的内容与浏览器类型有关则该值非常有用
                request.UserAgent = "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/67.0.3396.99 Safari/537.36";

                request.ContentType = "application/x-www-form-urlencoded; charset=UTF-8";
                //请求方式

                request.Headers.Add("Accept-Encoding", "gzip, deflate");
                //表示请求消息正文的长度
                request.ContentLength = data.Length;
                Stream postStream = request.GetRequestStream();
                request.CookieContainer = new CookieContainer();
                byte[] postData = Encoding.UTF8.GetBytes(data);
                //将传输的数据，请求正文写入请求流
                postStream.Write(postData, 0, postData.Length);
                postStream.Dispose();
                //响应
                string StrDate = ""；
                HttpWebResponse response = (HttpWebResponse)request.GetResponse();
                cookie.Add(response.Cookies);
                MessageBox.Show("获取到cookies" + response.Cookies);
                Stream str = response.GetResponseStream();
                StreamReader Reader = new StreamReader(str, Encoding.Default);
                while ((StrDate = Reader.ReadLine()) != null)
                {
                    result += StrDate + "\r\n";
                } 
               // 判断响应的信息是否为压缩信息 若为压缩信息解压后返回
                if (response.ContentEncoding == "gzip")
                {
                    MemoryStream ms = new MemoryStream();
                    GZipStream zip = new GZipStream(response.GetResponseStream(), CompressionMode.Decompress);
                    byte[] buffer = new byte[1024];
                    int l = zip.Read(buffer, 0, buffer.Length);
                    while (l > 0)

            }
