推荐答案

如果它是文件，并且您正在尝试上传特定的媒体类型， 标题"Content-Type":"application/x-www-form-urlencoded"对我来说似乎不正确.在这里查看适当的媒体类型:

If it's a file and you are trying to upload a particular media type, the header 'Content-Type': 'application/x-www-form-urlencoded' does not seem right to me. Have a look at the appropriate media type here:

http://www.iana.org/assignments/media- types/media-types.xhtml

另外，您将数据序列化为JSON，如果您的数据是二进制的，则需要将其更改为字节数组.

Also, you serialize data to JSON, if your data is binary you will need to change that to a byte array.

您可能会在这里找到一些有用的信息:

还要在URL和标头中都设置一个令牌，我建议仅在标头中设置它.

Also you set a token both in your URL and your header, I'd recommend to set it in the header only.
