xcode - How to upload image with parameters using Alamofire in Swift

Question

I am developing an iPhone application with swift. and I'am using Alamofire framework for handling http requests. I use Alamofire.request for POST , GET and etc like this:

Alamofire.request(.POST, myURL , parameters: ["a": "1", "b" : "2" ])
        .response { (request, response, data, error) in
}  

And I use Alamofire.upload to upload image to server this :

Alamofire.upload(.POST, uploadURL , fileURL)

And both works perfectly, but now I want to upload an image and also send some parameters with, and my content type should be multipart/form-data and Alamofire.upload does not accept parameters.

There are two more question on SO about this issue with swift, which first one is not using Alamofire (and really, why not?) and in second one, mattt (Alamofire Developer) cited to use encoding parameters.

I checked his example, but still couldn't figure out how to do that.

Can any one please help me solve this problem?

Thank you! :)

Answer 1

you can use Alamofire 3.0+ below code

func uploadImageAndData(){
    //parameters
    let gender    = "M"
    let firstName = "firstName"
    let lastName  = "lastName"
    let dob       = "11-Jan-2000"
    let aboutme   = "aboutme"
    let token     = "token"

    var parameters = [String:AnyObject]()
    parameters = ["gender":gender,
                  "firstName":firstName,
                  "dob":dob,
                  "aboutme":about,
                  "token":token,
                  "lastName":lastName]

    let URL = "http://yourserviceurl/"
    let image = UIImage(named: "image.png")

    Alamofire.upload(.POST, URL, multipartFormData: {
        multipartFormData in

        if let imageData = UIImageJPEGRepresentation(image, 0.6) {
            multipartFormData.appendBodyPart(data: imageData, name: "image", fileName: "file.png", mimeType: "image/png")
        }

        for (key, value) in parameters {
            multipartFormData.appendBodyPart(data: value.dataUsingEncoding(NSUTF8StringEncoding)!, name: key)
        }
    }, encodingCompletion: {
        encodingResult in

        switch encodingResult {
        case .Success(let upload, _, _):
            print("s")
            upload.responseJSON { 
                response in
                print(response.request)  // original URL request
                print(response.response) // URL response
                print(response.data)     // server data
                print(response.result)   // result of response serialization

                if let JSON = response.result.value {
                    print("JSON: (JSON)")
                }
            }
        case .Failure(let encodingError):
            print(encodingError)
        }
    })
}
