I am able to upload the file using pure okhttp code but not quite able to replicate it using retrofit2, I do not want entry of credentials because that isn't required in the case of okhttp so shouldn't be required here as well (I assume).
Following is my okhttp code.

val client = OkHttpClient()

val file = File(pathOfFileToSend)

val requestFile = okhttp3.RequestBody.create(okhttp3.MediaType.parse("image/jpeg"), file)

val body = MultipartBody.Builder()

for (field in mS3Params!!.post_params!!.fields) {

    body.addFormDataPart(field.name ?: "", field.value ?: "")

}

body.addPart(Headers.of("Content-Disposition", "form-data; name="file""),requestFile)

val request = Request.Builder()

                .url(BuildConfig.S3_IMAGE_SERVER_URL)

                .post(body.build())

                .build()

val response = client.newCall(request).execute()

if (!response.isSuccessful) {

   //Success

} else {

   //Fail

}

This above code works perfectly fine. Sharing my mS3Params for reference as well.

class S3ImageParamsResponseModel {

var action: String? = null

var card_id: String? = null

var image_url: String? = null

var post_params: PostParams? = null



class PostParams {

    lateinit var fields: List<Field>



    override fun toString(): String {

        return "PostParams{" +

                "fields=" + fields +

                '}'.toString()

    }

}



class Field {

    var name: String? = null

    var value: String? = null



    override fun toString(): String {

        return "Field{" +

                "name='" + name + '''.toString() +

                ", value='" + value + '''.toString() +

                '}'.toString()

    }

}



override fun toString(): String {

    return "S3ImageParamsResponseModel{" +

            "action='" + action + '''.toString() +

            ", card_id='" + card_id + '''.toString() +

            ", image_url='" + image_url + '''.toString() +

            ", post_params=" + post_params!!.toString() +

            '}'.toString()

}

Now I am unable to convert the above into a retrofit2/rxjava request. My code is always giving 405 exception. Here are the two trials.

Trial 1 -

val file = File(pathOfFileToSend)

        Timber.d(TAG, "onRun: length=" + file.length())



        val descriptionPart = RequestBody.create(MultipartBody.FORM, "imageFile")



        val requestFile = RequestBody.create(MediaType.parse("image/jpeg"), file)



        val filePart = MultipartBody.Part.createFormData("photo", "imageFile",

                requestFile)



        val httpClient = OkHttpClient.Builder()

        httpClient.addNetworkInterceptor(StethoInterceptor())

        val client = httpClient.build()

        val retrofit = Retrofit.Builder()

                .baseUrl(BuildConfig.S3_IMAGE_SERVER_URL)

                .addCallAdapterFactory(RxJava2CallAdapterFactory.create())

                .addConverterFactory(GsonConverterFactory.create())

                .client(client)

                .build()

        val uploadService = retrofit.create(FreshClient::class.java)

        val uploads = uploadService.uploadFile(mS3Params!!.image_url!!,

                descriptionPart, filePart)



        uploads.subscribeOn(Schedulers.newThread())

                .observeOn(AndroidSchedulers.mainThread())

                .subscribe(object : DisposableObserver<ResponseBody>() {

                    override fun onComplete() {



                    }



                    override fun onError(e: Throwable) {

                        Timber.d("", "")

                    }



                    override fun onNext(uploadData: ResponseBody) {

                        Timber.d("", "")

                    }

                })

Trial 2 -

val file = File(pathOfFileToSend)

        Timber.d(TAG, "onRun: length=" + file.length())



        val descriptionPart = RequestBody.create(MultipartBody.FORM, "imageFile")



        val requestFile = RequestBody.create(MediaType.parse("image/jpeg"), file)



        val body = MultipartBody.Builder()



        for (field in mS3Params!!.post_params!!.fields) {

            body.addFormDataPart(field.name ?: "", field.value ?: "")

        }



        body.addPart(

                Headers.of("Content-Disposition", "form-data; name="file""),

                requestFile)



        val httpClient = OkHttpClient.Builder()

        httpClient.addNetworkInterceptor(StethoInterceptor())

        val client = httpClient.build()

        val retrofit = Retrofit.Builder()

                .baseUrl(BuildConfig.S3_IMAGE_SERVER_URL)

                .addCallAdapterFactory(RxJava2CallAdapterFactory.create())

                .addConverterFactory(GsonConverterFactory.create())

                .client(client)

                .build()

        val uploadService = retrofit.create(FreshClient::class.java)

        val uploads = uploadService.uploadFile(mS3Params!!.image_url!!,

                descriptionPart, body.build().part(0))



        uploads.subscribeOn(Schedulers.newThread())

                .observeOn(AndroidSchedulers.mainThread())

                .subscribe(object : DisposableObserver<ResponseBody>() {

                    override fun onComplete() {



                    }



                    override fun onError(e: Throwable) {

                        Timber.d("", "")

                    }



                    override fun onNext(uploadData: ResponseBody) {

                        Timber.d("", "")

                    }

                })

And my service in both cases is as follows -

@Multipart

@POST("")

fun uploadFile(@Url url: String,

               @Part("description") description: RequestBody,

               @Part file: MultipartBody.Part): Observable<ResponseBody>

Please help out how to convert a working okhttp code to retrofit2/rxjava.
