Alamofire 4.0 Upload MultipartFormData Header

Question

How do we add an authentication header to the upload function of Alamofire 4.0?

below is the sample code, however I see no way in adding a header to the function.

Alamofire.upload(
    multipartFormData: { multipartFormData in
        multipartFormData.append(unicornImageURL, withName: "unicorn")
        multipartFormData.append(rainbowImageURL, withName: "rainbow")
    },
    to: "https://httpbin.org/post",
    encodingCompletion: { encodingResult in
        switch encodingResult {
        case .success(let upload, _, _):
            upload.responseJSON { response in
                debugPrint(response)
            }
        case .failure(let encodingError):
            print(encodingError)
        }
    }
)

Previous version of alamofire supported adding header directly, but not the new one. Any ideas?

Solution

I got the solution.

Alamofire.upload(multipartFormData:{ multipartFormData in
         multipartFormData.append(unicornImageURL, withName: "unicorn")
         multipartFormData.append(rainbowImageURL, withName: "rainbow")},
       usingThreshold:UInt64.init(),
       to:"https://httpbin.org/post",
       method:.post, 
       headers:["Authorization": "auth_token"], 
       encodingCompletion: { encodingResult in
        switch encodingResult {
        case .success(let upload, _, _):
            upload.responseJSON { response in
                debugPrint(response)
            }
        case .failure(let encodingError):
            print(encodingError)
        }
    })

Hope it will help you.
