When i try to upload the gzip file it adds multiform header which breaks my gzip reader because of the Content-Type header

curl -X 'POST'
'http://localhost:3013/test'
-H 'accept: application/json'
-H 'X-REQUEST-SIGNATURE: test'
-H 'Content-Type: multipart/form-data'
-F 'file=@test.json.gz;type=application/gzip'

I need it to be application/gzip, is there any solution for this problem? Thank you in advance.

The issue is actually in your go implementation.
a multipart-form data looks like the following. Each element from multipart form has his own content-type as you may actually see int the CURL example command.

POST / HTTP/1.1
[[ Less interesting headers ... ]]
Content-Type: multipart/form-data; boundary=---------------------------735323031399963166993862150
Content-Length: 834

-----------------------------735323031399963166993862150
Content-Disposition: form-data; name="text1"

text default
-----------------------------735323031399963166993862150
Content-Disposition: form-data; name="text2"

aωb
-----------------------------735323031399963166993862150
Content-Disposition: form-data; name="file1"; filename="a.txt"
Content-Type: text/plain

Content of a.txt.

-----------------------------735323031399963166993862150
Content-Disposition: form-data; name="file2"; filename="a.html"
Content-Type: text/html

<!DOCTYPE html><title>Content of a.html.</title>

-----------------------------735323031399963166993862150
Content-Disposition: form-data; name="file3"; filename="binary"
Content-Type: application/octet-stream

I was saying, is there any way I can write in documentation using annotations that I am uploading a gzip file not like form data but like a gzip:

// @Param gzip formData file true "Application gzip file"

because I need to upload binary gzip file. On postman this curl works:

curl --location --request POST 'http://localhost:3013/test' \ --header 'X-REQUEST-SIGNATURE: test==' \ --header 'Authorization: Basic test=' \ --header 'Content-Type: application/gzip' \ --data-binary '@/home/test/test.json.gz'

I had to edit my code and add support for multipart, because i cant send request from swagger without it.

if strings.HasPrefix(req.Header.Get("Content-Type"), "multipart/") { r, err = supportMultiParRequest(req) if err != nil { logger.LogError("Invalid JSON data", err) renderer.Renderer.Error(req, res, http.StatusInternalServerError, err.Error()) return } } else { r, err = gzip.NewReader(req.Body) if err != nil { logger.LogError("Invalid JSON data", err) renderer.Renderer.Error(req, res, http.StatusInternalServerError, err.Error()) return } }

If you want to use binary, you can use "octet-stream" for application/octet-stream. On the other hand, application/gzip can be added, but it won't say too much about the content type.
