DocuSign NO_DOCUMENT_RECEIVED

Question

我正在关注Docusign指南上传PDF以进行签名。我收到错误消息NO_DOCUMENT_RECEIVED。你能指导一下导致这种情况的原因吗？我使用的是JDK 8 / Win 7 / 64bit，IDE是Netbeans 7.0.0.1

TIA！ 鲁

重写默认的initializeRequest以处理多部分上传，因此在上传之前，在其他所有情况下将multipart值更改为true，例如login将其设置为false。

private static HttpURLConnection initializeRequest(String url, String method,
            String body, String httpAuthHeader, Boolean multipart) {
        HttpURLConnection conn = null;
try {
            conn = (HttpURLConnection) new URL(url).openConnection();

            conn.setRequestMethod(method);
            conn.setRequestProperty("X-DocuSign-Authentication", httpAuthHeader);
            conn.setRequestProperty("Accept", "application/xml");
            conn.setDoOutput(true);
            if (multipart) {
                conn.setRequestProperty("Content-Type", "multipart/form-data; boundary=BOUNDARY");
            } else {
                conn.setRequestProperty("Content-Type", "application/xml");
                if (method.equalsIgnoreCase("POST") || method.equalsIgnoreCase("PUT") || method.equalsIgnoreCase("DELETE")) {
                    conn.setRequestProperty("Content-Length", Integer.toString(body.length()));
                    DataOutputStream dos = new DataOutputStream(conn.getOutputStream());
                    dos.writeBytes(body);
                    dos.flush();
                    dos.close();
                }
            }
            return conn;
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
    }
