Docusign-打开通过Rest API下载的PDF时出错 [英] Docusign - Error opening PDF downloaded through the Rest API

问题描述

使用REST API，我试图从完整的信封中取出文档。我的标头使用X-DocuSign-Authentication。

  EnvelopesApi ap = new EnvelopesApi（）; 
编码encoding = System.Text.Encoding.GetEncoding（ utf-8）; 
 
 EnvelopeDocumentsResult edr = ap.ListDocuments（（AccountId， xxx-xx-xxx）; 
 
 List< EnvelopeDocument> docs = edr.EnvelopeDocuments; 
 
 foreach（文档中的EnvelopeDocument doc）
 {
 Stream stream1 = ap.GetDocument（AccountId， xxx-xx-xxx，doc.DocumentId）； 
 StreamReader阅读器=新系统.IO.StreamReader（stream1，encoding）; 
 var data = reader.ReadToEnd（）; 
 StreamWriter writer = new StreamWriter（@ C：\mysigneddoc.pdf）; 
 writer .write（data）; 
 writer.Close（）; 
} 
  

尝试打开完整的pdf时，出现错误，指出

签名人身份尚未得到验证。

有什么想法可能会出错吗？

解决方案

请查看API配方

  var ap = new EnvelopesApi（ ）; 
 var edr = ap.ListDocuments（（AccountId， xxx-xx-xxx）; 
 List< EnvelopeDocument> docs = edr.EnvelopeDocuments; 
 
 foreach（EnvelopeDocument doc in docs）
 {
 // API调用GetDocument（）返回一个MemoryStream 
 var docStream =（MemoryStream）envelopesApi.GetDocument（accountId，envelopeId，doc.DocumentId）; 
 //让我们将文档保存到本地文件系统
 filePath = @ C：\temp\ + Path.GetRandomFileName（）+ .pdf; 
 fs = new FileStream（filePath，FileMode.Create ）; 
 docStream.Seek（0，SeekOrigin.Begin）; 
 docStream.CopyTo（fs）; 
 fs.Close（）; 
} 
  

您还可以使用 GetEnvelopeDocuments api。您无需查询每个文档。

• 组合PDF

传递字符串 combined 作为documentId。

检索包含所有文档和证书的组合内容的PDF。

 字符串信封ID = XXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX； 
字符串accountId = XXXXXX; 
 var envApi = new EnvelopesApi（）; 
 
 // GetDocument（）API调用返回MemoryStream 
 var docStream =（MemoryStream）envApi.GetDocument（accountId，envelopeId， combined）; 
 //将文档保存到本地文件系统
字符串filePath = @ C：\temp\ + Path.GetRandomFileName（）+ .pdf; 
 var fs = new FileStream（filePath，FileMode.Create）; 
 docStream.Seek（0，SeekOrigin.Begin）; 
 docStream.CopyTo（fs）; 
 fs.Close（）;

• ZIP文件

将字符串 archive 作为documentId传递

检索包含所有PDF文档，证书以及用于语音身份验证的任何.WAV文件的ZIP存档。

  var envApi = new EnvelopesApi（）; 
 
 // GetDocument（）API调用返回MemoryStream 
 var docStream =（FileStream）envApi.GetDocument（accountId，envelopeId， archive）; 
 //将文档保存到本地文件系统
字符串filePath = @ C：\temp\ + Path.GetRandomFileName（）+ .zip; 
 var fs = new FileStream（filePath，FileMode.Create）; 
 docStream.Seek（0，SeekOrigin.Begin）; 
 docStream.CopyTo（fs）; 
 fs.Close（）; 
  

With the REST api, I am trying to get the documents out of a completed envelope. My header is using X-DocuSign-Authentication.

EnvelopesApi ap = new EnvelopesApi();
Encoding encode = System.Text.Encoding.GetEncoding("utf-8");

EnvelopeDocumentsResult edr = ap.ListDocuments((AccountId, "xxx-xx-xxx");

List<EnvelopeDocument> docs = edr.EnvelopeDocuments;

foreach(EnvelopeDocument doc in docs)
{  
   Stream stream1 = ap.GetDocument(AccountId, "xxx-xx-xxx", doc.DocumentId);
   StreamReader reader = new System.IO.StreamReader(stream1, encode);
   var data = reader.ReadToEnd();
   StreamWriter writer = new StreamWriter(@"C:\mysigneddoc.pdf");
   writer.Write(data);
   writer.Close();
}

When I try to open the completed pdf, I get the error stating that

the signers identity has not been verified.

Any ideas where I might be going wrong?

解决方案

Please look at the API recipe here to download the documents from an envelope.

var ap = new EnvelopesApi();
var edr = ap.ListDocuments((AccountId, "xxx-xx-xxx");
List<EnvelopeDocument> docs = edr.EnvelopeDocuments;

foreach(EnvelopeDocument doc in docs)
{
  // GetDocument() API call returns a MemoryStream
  var docStream = (MemoryStream)envelopesApi.GetDocument(accountId, envelopeId, doc.DocumentId);
  // let's save the document to local file system
  filePath = @"C:\temp\" + Path.GetRandomFileName() + ".pdf";
  fs = new FileStream(filePath, FileMode.Create);
  docStream.Seek(0, SeekOrigin.Begin);
  docStream.CopyTo(fs);
  fs.Close();
}

You can also download the combined documents in an envelope using the GetEnvelopeDocuments api. You are not required to query for each individual document.

• Combined PDF

Pass the string combined as the documentId.

Retrieve a PDF that contains the combined content of all documents and the certificate.

string envelopeId = "XXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX";
string accountId = "XXXXXX";
var envApi = new EnvelopesApi();

// GetDocument() API call returns a MemoryStream
var docStream = (MemoryStream)envApi.GetDocument(accountId, envelopeId, "combined");
// let's save the document to local file system
string filePath = @"C:\temp\" + Path.GetRandomFileName() + ".pdf";
var fs = new FileStream(filePath, FileMode.Create);
docStream.Seek(0, SeekOrigin.Begin);
docStream.CopyTo(fs);
fs.Close();

---

• ZIP file

Pass the string archive as documentId

Retrieve a ZIP archive that contains all of the PDF documents, the certificate, and any .WAV files used for voice authentication.

var envApi = new EnvelopesApi();

// GetDocument() API call returns a MemoryStream
var docStream = (FileStream)envApi.GetDocument(accountId, envelopeId, "archive");
// let's save the document to local file system
string filePath = @"C:\temp\" + Path.GetRandomFileName() + ".zip";
var fs = new FileStream(filePath, FileMode.Create);
docStream.Seek(0, SeekOrigin.Begin);
docStream.CopyTo(fs);
fs.Close();
