Question

我在ASP.NET网站（WebForms，v4.5）工作。我正在为这个网站提供Docu-Sign集成解决方案。我尝试了REST API调用来发起电子签名请求，下载签名文档..etc（对我来说很好）。现在我正致力于获取多个信封ID的状态。端点为{vx}/accounts/{accountid}/envelopes/status

现在，我正在进行的PUT请求产生以下错误：

远程服务器返回错误：（400）错误请求。

代码段如下：

string username = "YOUR_USERNAME";
string password = "YOUR_PASSWORD";
string integratorKey = "YOUR_INTEGRATOR_KEY";
string url = "https://demo.docusign.net/restapi/v2/login_information";
string baseURL = ""; 
string accountId = ""; 

string authenticateStr =
    "<DocuSignCredentials>" +
    "<Username>" + username + "</Username>" +
    "<Password>" + password + "</Password>" +
    "<IntegratorKey>" + integratorKey + "</IntegratorKey>" +
    "</DocuSignCredentials>";

// 
// STEP 1 - Login
//
try
{
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
    request.Headers.Add("X-DocuSign-Authentication", authenticateStr);
    request.Accept = "application/xml";
    request.Method = "GET";
    HttpWebResponse webResponse = (HttpWebResponse)request.GetResponse();
    StreamReader sr = new StreamReader(webResponse.GetResponseStream());
    string responseText = sr.ReadToEnd();
    using (XmlReader reader = XmlReader.Create(new StringReader(responseText)))
    {
        while (reader.Read())
        { // Parse the xml response body
            if ((reader.NodeType == XmlNodeType.Element) && (reader.Name == "accountId"))
                accountId = reader.ReadString();
            if ((reader.NodeType == XmlNodeType.Element) && (reader.Name == "baseUrl"))
                baseURL = reader.ReadString();
        }
    }
    //
    // STEP 2 - Get Envelope Status(es)
    //

    string envlpIds = "<envelopeIds><string>2e552785-3e1c-458b-9513-9778f59b37ae</string><string>0c0844fc-148f-4c2f-a16a-765a73a8efe0</string></envelopeIds>";

    request = (HttpWebRequest)WebRequest.Create(baseURL + "/envelopes/status");
    request.Headers.Add("X-DocuSign-Authentication", authenticateStr);
    request.Accept = "application/xml";
    request.Method = "PUT";
    request.ContentType = "application/xml";
    request.ContentLength = envlpIds.Length;

    byte[] body = System.Text.Encoding.UTF8.GetBytes(envlpIds);
    Stream dataStream = request.GetRequestStream();
    dataStream.Write(body, 0, envlpIds.Length);
    dataStream.Close();

    // read the response
    webResponse = (HttpWebResponse)request.GetResponse();
    sr.Close();
    responseText = "";
    sr = new StreamReader(webResponse.GetResponseStream());
    responseText = sr.ReadToEnd();

    //--- display results
    lblmsg.Text = responseText;
}
catch (Exception ex)
{
    lblmsg.Text = ex.Message;
}

我在这里缺少什么？请帮我解决这个问题？

更新：

尝试包装信封ID如下：

<envelopeIds>
    <envelopeId>2e552785-3e1c-458b-9513-9778f59b37ae</envelopeId>
    <envelopeId>0c0844fc-148f-4c2f-a16a-765a73a8efe0</envelopeId>
</envelopeIds>

仍然遇到同样的错误。

还尝试了附加的querysting参数，如下所示：

PUT /restapi/v2/accounts/######/envelopes/status?envelope_ids=request_body

也不起作用。

Answer 1

乍一看，我建议您尝试使用<envelopeId>代替<string>来包装每个信封ID：

<envelopeIds>
    <envelopeId>2e552785-3e1c-458b-9513-9778f59b37ae</envelopeId>
    <envelopeId>0c0844fc-148f-4c2f-a16a-765a73a8efe0</envelopeId>
</envelopeIds>

此外，REST API指南中的代码示例包含URI的查询字符串参数/值（ envelope_ids = request_body ）：

PUT /restapi/v2/accounts/######/envelopes/status?envelope_ids=request_body

您可以尝试添加该查询字符串参数/值，以查看是否有任何区别。

如果这些问题都没有解决您的问题，请更新您的问题以包含您的代码生成的XML请求正文，我将尝试提供进一步的反馈。（您可以使用Fiddler或类似工具轻松生成XML请求的跟踪。）

Answer 2

在xml上尝试了六个变种后，我放弃并选择使用contentType =“application / json”

request.ContentType = "application/json";

string envlpIds = "{\"envelopeIds\":[\"2e552785-3e1c-458b-9513-9778f59b37ae\",\"0c0844fc-148f-4c2f-a16a-765a73a8efe0\"]}";
