I have an API POST request that takes in form/data with both text (strings) and 1 image file. In postman, this is what it looks like, and it works perfectly :)

I am trying to send the same thing through a POST request on an android app through OKHTTP. Here is the code that I wrote:

        MediaType mediaType = MediaType.parse(getMimeType(imageFile.toURI().toURL().toString()));
        requestBody = new MultipartBody.Builder().setType(MultipartBody.FORM)
                .addFormDataPart("imageFile", imageFile.getName(), RequestBody.create(imageFile, mediaType))
                .addFormDataPart("machineKey", machineKey)
                .addFormDataPart("authToken", authToken)
                .addFormDataPart("UIID", UIID)
                .addFormDataPart("localItemID", localItemID)
                .addFormDataPart("itemName", itemName)
                .addFormDataPart("itemDescription", itemDescription)
                .addFormDataPart("itemPrice", itemPrice)
                .addFormDataPart("itemStock", itemStock)
                .addFormDataPart("itemAge", itemAge)
                .build();
    Request request = new Request.Builder()
            .url(URLString)
            .post(requestBody)
            .build();
    System.out.println("POST: calling: "  URLString);
    Response response = client.newCall(request).execute();

Here are a few notes to keep in mind :)

1. imageFile is the file if the image (and the file is guaranteed to always exist, and is accessible)

2. all strings are never null

   (getMimeType(imageFile.toURI().toURL().toString()) will return "image/jpeg" or "image/*", I have tried both

I am running this code asynchronously, and this code will post the string values correctly, but for some reason will not correctly post the image file. Any ideas? Thanks!

You are missing to set the content-type request header: .addHeader("content-type", "multipart/form-data")

Actually figured it out... turns out the files names I were sending were not sanitized, so some files being sent had illegal characters in its file name, so I got that fixed! thanks! :)
