How to upload image using multipart request with Moya Swift?

Question

I\'m using Moya 10.0.1 and I\'m having a problem when I\'m trying to upload an image to the server.

I did follow the Multipart Upload example and this is my setup code:<

Answer 1

    var task: Task {
    switch self {
    case .updateProfilePic(let memberID, let image):
        let imageData = UIImageJPEGRepresentation(image, 1.0)
        let memberIdData = memberID.data(using: String.Encoding.utf8) ?? Data()
        var formData: [Moya.MultipartFormData] = [Moya.MultipartFormData(provider: .data(imageData!), name: "user_img", fileName: "user.jpeg", mimeType: "image/jpeg")]
        formData.append(Moya.MultipartFormData(provider: .data(memberIdData), name: "member_id"))
        return .uploadMultipart(formData)
    }

In Moya multipart request we have to pass parameter as multipartdata form along with it's key name.

complete detail of uploading image using multipart request with Moya Swift. setp 1

 import Foundation
import Moya

enum ImageService {
    case updateUserAvatar(user_id: Int, cover_image: UIImage)
}
extension ImageService: TargetType {
    public var baseURL: URL { return URL(string: "https://api.shoclef.com/api")! }
    public var path: String {
        switch self {
        case .updateUserAvatar(_,_): return "/updatecoverimage"
        }
    }
    public var method: Moya.Method {
        switch self {
        case .updateUserAvatar(_, _):
            return .post
        }
    }
    var task: Task {
        switch self {

    case .updateUserAvatar(let user_id, let cover_image):
        let imageData = UIImageJPEGRepresentation(cover_image, 1.0)
        let memberIdData = "\(user_id)".data(using: String.Encoding.utf8) ?? Data()
        var formData: [Moya.MultipartFormData] = [Moya.MultipartFormData(provider: .data(imageData!), name: "cover_image", fileName: "asdas.png", mimeType: "image/jpeg")]
        formData.append(Moya.MultipartFormData(provider: .data(memberIdData), name: "user_id"))
        return .uploadMultipart(formData)
    }
}
public var sampleData: Data {
    return Data()
}
public var headers: [String : String]? {
    switch self {
    case .updateUserAvatar: return ["Content-type" : "application/json"]

    }}}

step 2

@IBOutlet weak var myImage: UIImageView!
    var provider = MoyaProvider<ImageService>()
 @IBAction func uploadImage(_ sender: UIButton) {
        provider.request(ImageService.updateUserAvatar(user_id: 1163, cover_image: myImage.image!)) { result in
            switch result {
            case .success(let response):
                do {

                    let image = try JSONDecoder().decode(Updatecoverimage.self, from: response.data)
                    print(image.data)
                } catch {
                    print(error)  // This code will run because the statusCode is 500
                }

            case .failure(let error):
                print("Failure: \(error)")
            }
        }

    }

}

    let status, data: String
