檢測是否有資料，如果有資料直接在方法中呼叫獲取證書PDF的方法“CertInfoPdf”
/// <summary> /// 檢測是否有證書 /// </summary> /// <param name="personalId"></param> /// <param name="name"></param> /// <param name="code"></param> /// <returns></returns>public ActionResult CheckHasCert(string personalId, string name, string code) { HttpCookie cookie = Request.Cookies["ValidateCode"]; if (cookie != null) { if (cookie.Value != code) { return Json(new{ success = false, msg = "驗證碼錯誤!" }); } } else { return Json(new { success = false, msg = "驗證碼錯誤!" }); } if (string.IsNullOrWhiteSpace(personalId)) { return Json(new { success = false, msg = "資料錯誤" }); } var certInfo = JobClient.GetCert(new JobCertSearch { PersonalId = personalId, Name = name }); if (certInfo == null || certInfo.JobCert == null) { return Json(new { success = false, msg = "暫無證書" }); } if (certInfo.FaceImage == null) { return Json(new { success = false, msg = "請先完善頭像資訊" }); } var certVm = certInfo.JobCert;return CertInfoPdf(personalId, EncodeBase64(Encoding.UTF8, name)); }
由於模板中有二維碼，掃碼二維碼也要展示相同的頁面，但是引數是中文時有問題，所以中文引數進行了下編碼，要掃碼看資料，就需要把方法的許可權放開，不能進行驗證“[CheckLogin(false)]”

if (string.IsNullOrWhiteSpace(personalId))

加密解密方法
/// <summary> /// base64解密 /// </summary> /// <param name="encode">編碼，與js一致</param> /// <param name="result">加密源字串</param> /// <returns></returns> public static string DecodeBase64(Encoding encode, string result) { string decode = ""; byte[] bytes = Convert.FromBase64String(result); try { decode = encode.GetString(bytes); } catch { decode = result; } return decode; } /// <summary> /// base64加密 /// </summary> /// <param name="encode">編碼，與js一致</param> /// <param name="source">加密源字串</param> /// <returns></returns> public static string EncodeBase64(Encoding encode, string source) { string decode = ""; byte[] bytes = encode.GetBytes(source); try { decode = Convert.ToBase64String(bytes); } catch { decode = source; } return decode; }
生成二維碼
public readonly string currentPath = @"/Content/QrCodeImg";
public void GetQrCode(string url, string certNumber) { QRCodeEncoder qrCodeEncoder = new QRCodeEncoder(); System.IO.MemoryStream ms = new System.IO.MemoryStream(); System.Drawing.Bitmap myimg = qrCodeEncoder.Encode(url, System.Text.Encoding.UTF8); //kedee 增加utf-8編碼，可支援中文漢字 SaveImg(currentPath, myimg, certNumber); ms.Dispose(); ms.Close(); }
前臺接收處理，接收到的字串賦值到iframe的src上，由於我用的layui，彈出層可以根據type決定型別，type值為2就是iframe彈出層，所以直接就賦值給彈出層了
