MultiPart를 이용한 이미지 업로드 하기

구현 방법

MultPart 어노테이션을 적용한 인터페이스 구성

    @Multipart
    @POST("profile/register")
    fun postCatProfile(
        @Header("token") token: String,
        @Part profileImg: MultipartBody.Part,
        @PartMap body: HashMap<String, RequestBody>
    ): Call<ResponseCatProfileData>

이미지 uri를 MultiPartBody.Part 타입으로 변경

    private fun settingImgMultiPart(): MultipartBody.Part {
        val options = BitmapFactory.Options()
        val inputStream = contentResolver.openInputStream(CatInfoData.catProfileUri!!)!!
        val bitmap = BitmapFactory.decodeStream(inputStream, null, options)
        val byteArrayOutputStream = ByteArrayOutputStream()
        bitmap!!.compress(Bitmap.CompressFormat.JPEG, 20, byteArrayOutputStream)
        val photoBody =
            RequestBody.create(MediaType.parse("image/jpg"), byteArrayOutputStream.toByteArray())

        return MultipartBody.Part.createFormData(
            "profileImg",
            File(CatInfoData.catProfileUri.toString()).name,
            photoBody
        )
    }

나머지 String 값은 HashMap으로 설정

val name = RequestBody.create(MediaType.parse(PARSE_STRING), CatInfoData.profileName)

mOunce.SERVICE.postCatProfile(
            token = accessToken,
            profileImg = pictureRb,

                "profileName" to name,
