Question

在Node-RED中，它具有“文档上层节点”，听起来可以将文件上传到Discovery Service，但是问题是我的客户端想要上传.doc文件。我当然尝试过，但是发现服务端将有效负载视为json，无法获得预期的结果...

我将Node-RED流的json附加为js代码段，可以重现该问题
仅供参考，还附上了上传结果 Document upload result

请让我知道是否有人可以帮助我...

真诚的感谢您：）

Answer 1

提供它是您要发送的真实的.doc文件，则它应该可以工作。该代码正在寻找.json对象或文件缓冲区。 .doc个文件将被视为缓冲区。我已经尝试了您的代码，并成功地将其加载到发现文档中，尽管文档加载的响应实际上在msg.document而非msg.payload上进行。

如何通过document-uploader-node将.doc类型的文件上传到Discovery服务？
