Moya: fatal error: Test is not a multipart upload target

[Dhvl-Golakiya]

Hi, I'm using Moya (8.0.0-beta.6) for uploading image and post parameters.

But I'm getting fatal error: Test("username") is not a multipart upload target error. My request's multipart body is empty.

I'm using following code:

This is APIProvider class

    class APIProvider {

    static let sharedInstance = APIProvider()

    internal static func endpointClosure(target: Appname) -> Endpoint<Appname> {
        let sampleResponseClosure = { return EndpointSampleResponse.networkResponse(200, target.sampleData) }
        let method = target.method
        let path = target.path
        let parameters = target.parameters
        return Endpoint<Appname>(url: Constants.API_URL + path, sampleResponseClosure: sampleResponseClosure, method: method, parameters: parameters, parameterEncoding: URLEncoding() )
    }

    var provider = RxMoyaProvider<Appname>(endpointClosure: APIProvider.endpointClosure)

    private init() {
        provider = RxMoyaProvider<Appname>(endpointClosure: APIProvider.endpointClosure)
    }

    //     MARK: - Upload image

    func getTestImage(name : String, image : UIImage) -> Observable<Test> {
        return self.provider
            .request(Appname.Test(name: name, image: image))
            .debug()
            .mapObject(Test.self)
    }

This is Endpoint:

      enum Appname {

    case Test(name : String, image : UIImage)
    }

      extension Nutrick : TargetType {
    var baseURL: URL {
        let url =  URL(string: Constants.API_URL)!
        print(url)
        return url
    }

    var path: String {
        switch self {
        case .Test:
            return "image"
        }

    }

    var method: Moya.Method {
        switch self {
        case .Test:
            return .post
        }
    }

    var parameters: [String: Any]? {
        switch self {
        case .Test(let name, _):
            return ["name" : name]
        }
    }

    var multipartBody: [MultipartFormData]? {
        switch self {
        case .Test(_, let image):

            let imageData = UIImageJPEGRepresentation(image, 1.0)
            let formData: [MultipartFormData] = [MultipartFormData(provider: .data(imageData!), name: "image", fileName: "photo.jpg", mimeType: "image/jpeg")]
            return formData


        default:
            return []
        }
    }

    var sampleData: Data {

        switch self {
        case .Test:
             return "{\"name\":\"1\",\"path\":\"User logged in successfully.\"}".data(using: String.Encoding.utf8)!
        }

    }

    var task : Task {
        switch self {

        case .Test:
            return .upload(UploadType.multipart([]))
        default:
            return .request
        }
    }
    }

If I set breakpoints on parameters and multipartBody vars then parameters breakpoint getting called but multipartBody breakpoint is not getting called. Is anything missing in APIProvider initialization? I already set task type to upload.

Please help me to fix this.

Hi,

me to have same issue, it was working before in previous version. Pleas suggest where i am wrong in implementation??

Hi,

The issue is fixed.

I'm sending an image in the multipart body instead of task.

Solution is:

 var task : Task {
        switch self {
        case .Test(_, let image):

            let imageData = UIImageJPEGRepresentation(image, 1.0)
            let formData: [MultipartFormData] = [MultipartFormData(provider: .data(imageData!), name: "image", fileName: "photo.jpg", mimeType: "image/jpeg")]
            return .upload(UploadType.multipart(formData))
        default:
            return .request
        }
    }

Thanks
