如果您将数据作为表单的一部分上传，则必须将 multipart/form-data 用于您的 Content-输入.

If you're uploading data as part of a form, you must use multipart/form-data for your Content-Type.

表单上特定文件的 Content-Type 可以为每个文件设置，但 Facebook 似乎不希望为此提供额外的数据.

The Content-Type for a particular file on a form can be set per-file, but it seems that Facebook doesn't want that extra data for this.

不要为你的 HTTP 请求设置 Content-Type ，你应该没问题，因为请求模块会为你设置它.此外，您可以在此处找到文档:https://github.com/request/request#multipartform-data-multipart-form-uploads

Don't set Content-Type for your HTTP request and you should be fine, as the Request module will set it for you. Also, you can find the documentation here: https://github.com/request/request#multipartform-data-multipart-form-uploads
