一、電子簽章:通過接口,傳入參數中有pdf文件,和其他參數,在文件上蓋上電子簽章。
引入:通過NuGet安裝RestSharp,注意版本。
備注:如果后面程序運行有錯,可以看是引用是否更改了web.config文件(一般會更改Newtonsoft.Json的版本)
代碼:
/// <summary> /// 電子簽章(蓋章) /// </summary> /// <param name="apiUrl"></param> /// <param name="filePath"></param> /// <param name="type">為1 表示報名確認函 為2 表示邀約人員名單</param> /// <returns></returns> public static string SendCaESignature(string apiUrl, string filePath, string type) { try { #region 初始化參數 string url = ConfigurationManager.AppSettings["caESignature"].ToString() + apiUrl; string picName = "***.gif"; string certName = "***.pfx"; string page = "0"; string posX = ""; string posY = ""; // 確認涵 x、y軸 string hanPosX = ConfigurationManager.AppSettings["hanPosX"].ToString(); string hanPosY = ConfigurationManager.AppSettings["hanPosY"].ToString(); // 邀約人員名單 string joinPosX = ConfigurationManager.AppSettings["joinPosX"].ToString(); string joinPosY = ConfigurationManager.AppSettings["joinPosY"].ToString(); // 不同名單,簽章位置不一樣 if (type == "1") { posX = hanPosX; posY = hanPosY; } else { posX = joinPosX; posY = joinPosY; } #endregion #region 將文件轉成二進制 byte[] fileContentByte = new byte[10240]; // 文件內容二進制 FileStream fs = new FileStream(filePath, FileMode.Open, FileAccess.Read); fileContentByte = new byte[fs.Length]; // 二進制文件 fs.Read(fileContentByte, 0, Convert.ToInt32(fs.Length)); fs.Close(); #endregion string postUrl = ConfigurationManager.AppSettings["caESignature"].ToString(); var restClient = new RestClient(postUrl); RestRequest re = new RestRequest(apiUrl, Method.POST); re.AddQueryParameter("picName", picName); re.AddQueryParameter("certName", certName); re.AddQueryParameter("page", page); re.AddQueryParameter("posX", posX); re.AddQueryParameter("posY", posY); re.AddFileBytes("pdfFile", fileContentByte, "報名確認涵", "application/octet-stream"); return restClient.Execute(re).Content; } catch (Exception e) { FileHelper.Log("電子簽章:" + e.Message); return ""; } }
二、下載電子簽章:通過接口下載二進制文件流
代碼:
/// <summary> /// 下載電子簽章 /// </summary> /// <param name="fileIden"></param> /// <returns></returns> public static string DownFileCA(string fileIden) { try { //創建本地緩存文件夾 string basePath = System.Web.HttpContext.Current.Server.MapPath("~/Temp/"); if (!Directory.Exists(basePath)) { Directory.CreateDirectory(basePath); } string filePath = basePath + string.Format("PDF_{0}.pdf", Guid.NewGuid().ToString("N")); string returnPath = ""; if (File.Exists(filePath)) {//如果已經存在,那么就不需要拷貝了,如果沒有,那么就進行拷貝 return returnPath; } else { FileStream fs = File.Create(filePath); fs.Close(); } string postUrl = ConfigurationManager.AppSettings["caESignature"].ToString(); var restClient = new RestClient(postUrl); RestRequest re = new RestRequest("/Signature/download", Method.POST); re.AddQueryParameter("fileIden", fileIden); byte[] byteArray = restClient.DownloadData(re); using (FileStream fs = new FileStream(filePath, FileMode.OpenOrCreate, FileAccess.Write)) { fs.Write(byteArray, 0, byteArray.Length); fs.Close(); } return filePath; } catch (Exception ex) { FileHelper.Log("電子簽章:" + ex.Message); return ""; } }
