如何通过文档上传器节点将.doc类型的文件上传到发现服务

Question

在Node RED中，它有"文档上传器节点"，听起来可以将文件上传到Discovery Service，但问题是我的客户端想要上传.doc文件。我当然试过了，但发现服务端将负载视为json，无法得到预期的结果。。。

• 我将Node RED flow的json作为js片段附加，可以重现问题
• 仅供参考，我还附上了上传结果文档上传结果

如果有人能帮我，请告诉我。。。

谢谢你，真诚的：(

如果它是您正在发送的真实.doc文件，那么它应该可以工作。代码正在查找.json对象或文件缓冲区。.doc文件将被视为缓冲区。我已经尝试了您的代码，并成功地将文档加载到发现中，尽管文档加载的响应实际上是在msg.document上，而不是在msg.payload上。
