我創建了一個接收Docusign網頁鉤的偵聽器頁面。儘管從webhook獲取數據,但所有內容都起作用,但是當我循環訪問DocumentPDF時,它會創建PDF文件,但它們已損壞且無法打開(當我嘗試在Acrobat中打開它時,我收到以下消息:Acrobat無法打開...因爲它是要麼不支持的文件類型或因爲該文件已損壞。「)已保存的Docusign文檔PDF已損壞
任何人可以幫助我弄清楚爲什麼創建的PDF文件被破壞?
我的代碼頁面如下:
protected void Page_Load(object sender, EventArgs e)
{
StreamReader sr = new StreamReader(Request.InputStream);
string xml = sr.ReadToEnd();
string fileName = HttpContext.Current.Server.MapPath("") + "\\Results\\" + DateTime.Now.Ticks + ".xml";
File.WriteAllText(fileName, xml);
try
{
XmlDocument xmldoc = new XmlDocument();
xmldoc.LoadXml(xml);
var mgr = new XmlNamespaceManager(xmldoc.NameTable);
mgr.AddNamespace("a", "http://www.docusign.net/API/3.0");
XmlNode envelopeStatus = xmldoc.SelectSingleNode("//a:EnvelopeStatus", mgr);
XmlNode envelopeId = envelopeStatus.SelectSingleNode("//a:EnvelopeID", mgr);
XmlNode status = envelopeStatus.SelectSingleNode("//a:Status", mgr);
if (status.InnerText == "Completed")
{
LogException("Looking for DocPDF's_" + DateTime.Now.Ticks + ";");
// Loop through the DocumentPDFs element, storing each document.
XmlNode docs = xmldoc.SelectSingleNode("//a:DocumentPDFs", mgr);
foreach (XmlNode doc in docs.ChildNodes)
{
string documentName = doc.ChildNodes[0].InnerText; // pdf.SelectSingleNode("//a:Name", mgr).InnerText;
string documentId = doc.ChildNodes[2].InnerText; // pdf.SelectSingleNode("//a:DocumentID", mgr).InnerText;
string byteStr = doc.ChildNodes[1].InnerText; // pdf.SelectSingleNode("//a:PDFBytes", mgr).InnerText;
LogException("Writing Out PDF_" + HttpContext.Current.Server.MapPath("") + "\\Documents\\" + envelopeId.InnerText + "_" + documentId + "_" + documentName + "_" + DateTime.Now.Ticks + ";");
File.WriteAllText(HttpContext.Current.Server.MapPath("") + "\\Documents\\" + envelopeId.InnerText + "_" + documentId + "_" + documentName, byteStr);
LogException("Successfully wrote out PDF_" + DateTime.Now.Ticks + ";");
}
}
}
catch (Exception ex)
{
LogException("Exception: " + ex.Message + "; InnerException: " + ex.InnerException.ToString() + "_" + DateTime.Now.Ticks + ";");
}
}
我不知道的DocuSign API,但寫一個PDF文檔的文本字符串也很難是正確的。可能'byteStr'是base64編碼的,你必須解碼才能得到實際的pdf? – mkl
