Upload file form uri using retrofit android with kotlin

Question

I am trying to upload a video using retrofit, but I can't generate the correct format this is my postman request :

postman request: https://i.stack.imgur.com/rDC6s.png

and this is the API endpoint call :

@POST("uploadVideo")
suspend fun uploadVideo(@Body body: UploadVideoRequest) : Response<DefaultResponse>

,Also this the "UploadVideoRequest" class :

data class UploadVideoRequest(
    @SerializedName("video")
    val video: RequestBody? = null
)

finally this is my call :

fun createPostWithVideo(fileName: String) {

    val file = File(fileName);
    val requestFile = RequestBody.create("multipart/form-data".toMediaTypeOrNull(), file)
    val body = MultipartBody.Part.createFormData("video", requestFile.toString())


    viewModel.uploadVideoRequest = UploadVideoRequest(
        video = body.body,
    )
    viewModel.uploadVideo()

}

But I am still not able to send that request

Answer 1

The way you are trying to send the video is not correct. Please follow these steps to send a video using retrofit. First, create a network interface like this.

@Multipart
@POST("uploadVideo")
suspend fun uploadVideo(@Part part: MultipartBody.Part) : Response<DefaultResponse>

Second, call function like this:

fun createMultipartBodyPart(file: File) {
    val requestBody = RequestBody.create("multipart/form-data".toMediaTypeOrNull(), file)
    val body = MultipartBody.Part.createFormData("name", file.name, requestBody)

    service.uploadVideo(body)
}
