Question

这是我的C＃.net代码。当我创建临时文档ID然后我发送文件签名然后我收到它空白文件。我认为临时文档id为空白文件创建。你可以帮忙吗？

public getDocumentId getTransientDocumentId(string accessToken, string path1,string filename)
    {
        getDocumentId objGet = new getDocumentId();                   

        var nvc = new NameValueCollection
        {
            {"File", path1},
            {"Content-Type", "multipart/form-data"},
            {"Mime-Type", "application/pdf"},
            {"File-Name", filename}
        };

        string boundary = "---------------------------" + DateTime.Now.Ticks.ToString("x");
        byte[] boundarybytes = System.Text.Encoding.ASCII.GetBytes("\r\n--" + boundary + "\r\n");
        byte[] boundarybytesF = System.Text.Encoding.ASCII.GetBytes("--" + boundary + "\r\n");  // the first time it itereates, you need to make sure it doesn't put too many new paragraphs down or it completely messes up poor webbrick.  

        HttpWebRequest wr = (HttpWebRequest)WebRequest.Create("https://api.na1.echosign.com/api/rest/v5/transientDocuments");
        wr.Method = "POST";
        wr.Headers["Access-Token"] = string.Format(accessToken);
        wr.Headers["Authorization"] = string.Format("Bearer");
        wr.UserAgent = "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_2) AppleWebKit/537.17 (KHTML, like Gecko) Chrome/24.0.1312.52 Safari/537.17";
        wr.KeepAlive = true;
        wr.Credentials = System.Net.CredentialCache.DefaultCredentials;
        wr.AllowWriteStreamBuffering = true;

        wr.ContentType = "multipart/form-data; boundary=" + boundary;

        Stream rs = wr.GetRequestStream();


        bool firstLoop = true;
        string formdataTemplate = "Content-Disposition: form-data; name=\"{0}\"\r\n\r\n{1}";
        foreach (string key in nvc.Keys)
        {
            if (firstLoop)
            {
                rs.Write(boundarybytesF, 0, boundarybytesF.Length);
                firstLoop = false;
            }
            else
            {
                rs.Write(boundarybytes, 0, boundarybytes.Length);
            }
            string formitem = string.Format(formdataTemplate, key, nvc[key]);
            byte[] formitembytes = System.Text.Encoding.UTF8.GetBytes(formitem);
            rs.Write(formitembytes, 0, formitembytes.Length);
        }
        rs.Write(boundarybytes, 0, boundarybytes.Length);
        string headerTemplate = "Content-Disposition: form-data; name=\"{0}\"; filename=\"{1}\"\r\nContent-Type: {2}\r\n\r\n";
        string header = string.Format(headerTemplate,  "File", new FileInfo(path1).Name, "application/octet-stream");
        byte[] headerbytes = System.Text.Encoding.UTF8.GetBytes(header);
        rs.Write(headerbytes, 0, headerbytes.Length);
        FileStream fileStream = new FileStream(path1, FileMode.Open, FileAccess.Read);
        byte[] buffer = new byte[fileStream.Length];
        int bytesRead = 0;
        while ((bytesRead = fileStream.Read(buffer, 0, buffer.Length)) != 0)
        {
            rs.Write(buffer, 0, bytesRead);
        }
        fileStream.Close();
        byte[] trailer = System.Text.Encoding.ASCII.GetBytes("\r\n--" + boundary + "--\r\n");
        rs.Write(trailer, 0, trailer.Length);
        rs.Close();
        try
        {
            var httpResponse = (HttpWebResponse)wr.GetResponse();
            using (var sr = new StreamReader(httpResponse.GetResponseStream()))
            {
                var result = sr.ReadToEnd();
                var jsonSerialization = new JavaScriptSerializer();
                var dictObj = jsonSerialization.Deserialize<Dictionary<string, dynamic>>(result);

                if (dictObj.Count > 0)
                {
                    objGet.transientDocumentId = Convert.ToString(dictObj["transientDocumentId"]);
                    objGet.success = "true";
                }
                else
                {
                    objGet.success = "false";
                }
            }     
        }
        catch (Exception ex)
        {
            objGet.success = "false: " + ex.Message.ToString();
        }
        return objGet;
    }

对于您希望使用transientDocument获取已附加到协议的文档的目的，您可以使用GET /agreements/{agreementId}/documents API调用获取这些文档。

但正如问题所说＆＃34;如何获得瞬态文件＆＃34;。好吧，你无法使用任何API获取transientDocument，原因是transientDocument是临时用途，通常用于创建单个协议并且是短暂的（仅7天）。如果您希望重新使用上载的文档来创建多个协议并且可以独立获取其文档，则应使用POST /libraryDocument

创建libraryDocument。

您可以对这些库文档执行GET API调用，以获取各种详细信息，如文档，auditTrail等。Here是您可以遵循的文档链接，以便更好地了解库文档
