Multer: Content-type = 'multipart/form-data', req.body, req.file still undefined

[jyjin]

I waste a lot of time to resolve this problem, I have tried to use html form element post data, and use FormData object post data. But it stile undefined in my req.body

shotcut for my http request:

my server code:

and server log:

Besides, .single(fieldname), Are this 'fieldname' is the formdata file key?

Hmm, the only thing I can think of is that something else is consuming the body before multer. Do you have any other middlewares that runs before this route?

[juanmav]

@LinusU I have the same issue and I have removed all middlewares to test it and still fails.

[LinusU]

Interesting, would you mind posting similar data as @jyjin did? I think it could help me debug the issue 😃

[jyjin]

I ve got the point，my problem made by I have a redirect server which didnt handle the request. so when a post a request , it lose the data on the middle redirect server. Now I pipe the request or temp save and resend formdata to final server，it worked！

[LinusU]

Glad to hear that you solved it!

@juanmav if you still have a problem and can share some more data I'll reopen this 👌
