How to make alamofire post request with "form-data" parameters

Question

How to make post request in swift using alamofire with parameters as below(screenshot from postman)image is file-type, title is text-type

I'm trying sth like this:

let headers = [
        "Content-Type": "application/form-data",
        "X-App-Token": user.token!
    ]
    Alamofire.upload(multipartFormData:{ multipartFormData in
        multipartFormData.append(UIImagePNGRepresentation(imgToSend)!, withName: "image")
        multipartFormData.append(titleToSend.data(using: .utf8)!, withName: "title")},
                     usingThreshold:UInt64.init(),
                     to: url!,
                     method:.post,
                     headers:headers,
                     encodingCompletion: { encodingResult in
                        switch encodingResult {
                        case .success(let upload, _, _):
                            upload.responseJSON { response in
                                debugPrint(response)
                            }
                        case .failure(let encodingError):
                            print(encodingError)
                        }
    })

but I got error: [BoringSSL] Function boringssl_session_errorlog: line 2868 [boringssl_session_write] SSL_ERROR_SYSCALL(5): operation failed externally to the library

and (this is weird) debugger goes into .success but when I log response there is error from api

Does this help ? https://stackoverflow.com/questions/33869058/using-form-data-with-alamofire — GoodSp33d, Jan 23 '18 at 13:16
Try changing `multipartFormData.append(UIImagePNGRepresentation(imgToSend)!, withName: "image")` to `multipartFormData.append(UIImagePNGRepresentation(imgToSend)!, withName: "image", fileName: "sample.png", mimeType: "image/png")` — Mukesh, Jan 23 '18 at 13:18
@GoodSp33d No, I know how to make normal requests, but this is specific one — Gorthez, Jan 23 '18 at 13:20

Try changing

multipartFormData.append(UIImagePNGRepresentation(imgToSend)‌!, withName: "image")

to

multipartFormData.append(UIImagePNGRepresentation(imgToSend)‌!, withName: "image", fileName: "sample.png", mimeType: "image/png")

If you're getting warning like:

line 2878 [boringssl_session_write] SSL_ERROR_SYSCALL(5): operation failed externally to the library

You can simply ignore it. This simply means that an operation on the TLS connection failed because the TLS was closed via the close_notify alert. This sort of thing is not a problem in and of itself.

You can disable OS logging in Xcode to make them go away. With your project window open, go to Project -> Scheme -> Edit Scheme... and add "OS_ACTIVITY_MODE" to the Environment Variables section and set its value to "disable". When you rerun the app those warnings should now not appear.

I'm trying to upload files using the fileName and mimeType parameters, but the error still happens: `line 2878 [boringssl_session_write] SSL_ERROR_SYSCALL(5): operation failed externally to the library` – Cenobyte321 Apr 13 '18 at 01:41
has anyone gotten passed this yet? I'm still experiencing this error even with this code. – user2726072 Jun 07 '18 at 13:13
@Mukesh did the same but still getting 2018-09-20 11:31:13.863005+0545 SDoky[325:23893] [BoringSSL] Function boringssl_session_errorlog: line 2878 [boringssl_session_write] SSL_ERROR_SYSCALL(5): operation failed externally to the library – dip Sep 20 '18 at 05:47
