问题：
尝试创建带有多个文档的DocuSign信封
东郭自强
我试图使用DocuSign REST API创建一个包含多个文档的信封，我创建了一个C#控制台应用程序，并以JSON格式在请求中写入了信封参数。我得到了错误代码“信封不完整”，我试图将我的请求与REST API Docusign指南中的请求进行比较，但我看不到我遗漏了什么。下面是我的示例代码：
public class RequestSignature
{
// Enter your info here:
static string email = "email";
static string password = "password";
static string integratorKey = "key";
public static void Main()
{
string url = "https://demo.docusign.net/restapi/v2/login_information";
string baseURL = ""; // we will retrieve this
string accountId = ""; // will retrieve
var objectCredentials = new { Username = email, Password = password, IntegratorKey = integratorKey };
string jSONCredentialsString = JsonConvert.SerializeObject(objectCredentials);
//
// STEP 1 - Login
//
try
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
// request.Headers.Add("X-DocuSign-Authentication", authenticateStr);
request.Headers.Add("X-DocuSign-Authentication", jSONCredentialsString);
request.Accept = "application/json";
request.Method = "GET";
HttpWebResponse webResponse = (HttpWebResponse)request.GetResponse();
StreamReader sr = new StreamReader(webResponse.GetResponseStream());
string responseText = sr.ReadToEnd();
// close stream reader
sr.Close();
JsonTextReader reader = new JsonTextReader(new StringReader(responseText));
JObject jObject = JObject.Parse(responseText);
// get the first User Account data
JToken jUserAccount = jObject["loginAccounts"].First;
// read values from JSON
accountId = (string)jUserAccount["accountId"];
baseURL = (string)jUserAccount["baseUrl"];
//
// STEP 2 - Send Envelope with Information
//
// construct an outgoing JSON request body that create the envelope
string formDataBoundary = String.Format("{0:N}", Guid.NewGuid());
StringBuilder requestBody = new StringBuilder();
string header = string.Format("--{0}\r\nContent-Type: application/json\r\nContent-Disposition: form-data\r\n\r\n", formDataBoundary);
// Documents list to send in the envelope
List<Document> envelopeDocuments = new List<Document>();
Document currentDocument = new Document(1, "ABC.pdf", "C:/Documents/ABC.pdf");
envelopeDocuments.Add(currentDocument);
DocuSignDocument[] documentsArray = (from doc in envelopeDocuments
select new DocuSignDocument()
{
documentId = doc.DocumentID.ToString(),
name = doc.Name
}).ToArray();
//currentDocument = new Document(2, "ABC.pdf", "D:/Documents/ABC.pdf");
//envelopeDocuments.Add(currentDocument);
// creaqte recipients

}
}
};

recipients.Add(firstRecipient);
// api json attributes setting by developer
// setting attributes for the envelope request

我认为问题出在您发送的JSON上。它是有效的JSON格式，但是recipientId的值被删除或没有设置。收件人有以下内容：
"recipientId": null,
若要解决此问题，请将其设置为
"recipientId": "1",
或者您想为它设置的任何值，因为它是用户可配置的。例如，如果需要，可以将其设置为“4321”。
"signHereTabs": [
{
"documentId": "1",
"pageNumber": "1",
"xPosition": "100",
"yPosition": "100"
}
]
CRLF (\r\n)
性格。这是它需要的格式：
--AAA
Content-Type: application/json
Content-Disposition: form-data
<YOUR VALID JSON GOES HERE>
--AAA
Content-Disposition: form-data
Content-Type: multipart/mixed; boundary=BBB
--BBB
Content-Type:application/pdf
Content-Disposition: file; filename=\”document1.pdf"; documentid=1
<PDF Bytes for first document>
--BBB
Content-Type:application/pdf
Content-Disposition: file; filename=\”document2.pdf"; documentid=2
<PDF Bytes for second document>
--BBB--
--AAA--
如果您只发送一个文档，那么您的间距需要完全如下所示：
--AAA
Content-Type: application/json
Content-Disposition: form-data
<YOUR VALID JSON GOES HERE>
--AAA
Content-Type:application/pdf
Content-Disposition: file; filename="document.pdf"; documentid=1
<DOCUMENT BYTES GO HERE>
--AAA--

我知道在最新版本的Mongoose中，您可以将多个文档传递给create方法，在我的例子中，甚至可以传递一个文档数组。 我的问题是数组的大小是动态的，所以在回调中创建一个对象数组会很有帮助。 文档中没有，但这样做可能吗？

使用C#、DocuSign API SDK 4.5.2。 我在同一个信封里寄出三份文件供签名。每个文档将使用相同的服务器模板（它只是使用锚标记将签名元素放置在文档上）。我可以寄出信封，然后从DocuSign收到电子邮件，查看/签署文件。 我遇到的问题是，当我去签名时，我必须在每个文档上签名3次--总共9次--然后才允许单击Finish按钮。每个文件只有一个地方可以签名，但我必须点击签名按钮3次才能
