我在从Connect获得的响应中提取数据时遇到问题。我可以看到端点正在获得两个POST，但我没有看到数据，因为console.log（req）报告了所有内容，但我找不到这些信息。
我正在使用ngrok公开我的端点，并且我已配置Connect以在信封签名上发送带有XML更新的文档。
要说明问题，您如何从请求中提取文档？
提前致谢。
编辑： 我使用util来输出整个req，但仍无法找到XML和文档字节所在的对象。它肯定不是正文。

编辑2： 我意识到有些事情是不对的。所以我做了一些查看，发现Node甚至没有接受XML，所以我使用的是一个模块来执行该操作，现在主体正在包含文档。唯一的问题是，当我试图保存它时，它已经损坏了，所以我正在研究它。

您必须确保在DocuSign Connect设置中启用将文档附加到Connect事件。
这里是你想要剥离PDFBytes的XML，然后在解码和保存为PDF时在本地处理它。
