Deprecated WWW still works however can't use UnityWebRequest to do the same task. Need help

Hi!

I have a piece of code that helps me upload images on imgur using the imgur api. I have a piece of code that works perfectly using the WWW class. I wanted to convert this to the UnityWebRequest class and it has been extremely problematic and I can’t seem to find a way of doing this thing correctly. Here’s the information:

Code that works without any problem:

private Dictionary<string, string> FormatHeadersForImgur()
    {
        Dictionary<string, string> headers = new Dictionary<string, string>
        {
            {
                "Authorization",
                "Client-ID myClientIDHere"
            },
            {
                "User-Agent",
                Application.platform + ":" + Application.identifier + ":" + Application.version +
                " someInfoHere"
            },
            {
                "X-Mashape-Key",
                "myXMashapeKeyHere"
            }
        };
        return headers;
    }

WWW uploadImage = new WWW("https://imgur-apiv3.p.mashape.com/3/image", imageAsByteArrayFromPNG, headers);
yield return uploadImage;

Code that I have tried #1 and is giving me a IMGUR401 error which is explained as: The request requires user authentication. Either you didn’t send send OAuth credentials, or the ones you sent were invalid.

List<IMultipartFormSection> requestData = new List<IMultipartFormSection>();
        requestData.Add(new MultipartFormDataSection("Authorization", "Client-ID myactualclientidhere"));
        requestData.Add(new MultipartFormDataSection("User-Agent", Application.platform + ":" + Application.identifier + ":" + Application.version + " someappspecificinfohere"));
        requestData.Add(new MultipartFormDataSection("X-Mashape-Key", "myactualmashapekeyhere"));
        requestData.Add(new MultipartFormDataSection("image", imageAsByteArrayFromPNG));
        UnityWebRequest imgurPostRequest = UnityWebRequest.Post("https://imgur-apiv3.p.mashape.com/3/image", requestData, imageAsByteArrayFromPNG);
UnityWebRequestAsyncOperation imgurPostOperation = imgurPostRequest.SendWebRequest();

Code that I have tried #2 and is giving me a IMGUR404 error which is explained as: Resource does not exist. This indicates you have requested a resource that does not exist. For example, requesting an image that doesn’t exist.

UnityWebRequest imgurPostRequest = UnityWebRequest.Put("https://imgur-apiv3.p.mashape.com/3/image", imageAsByteArrayFromPNG);
        imgurPostRequest.SetRequestHeader("Authorization", "Client-ID myactualclientidhere");
        imgurPostRequest.SetRequestHeader("User-Agent", Application.platform + ":" + Application.identifier + ":" + Application.version + " someappspecificinfohere");
        imgurPostRequest.SetRequestHeader("X-Mashape-Key", "myactualmashapekeyhere");
        UnityWebRequestAsyncOperation imgurPostOperation = imgurPostRequest.SendWebRequest();

I’d like to know what I’m doing wrong and do it right. I’m confident there are no errors in terms of the api call since I have an already working case up top. So I must be doing something wrong with the UnityWebRequest class.

Code that I have tried #3 and worked: I also found another bit of code that works which doesn’t employ WWW or UnityWebRequest for that matter. Below is the code.

using (WebClient webClient = new WebClient())
        {
            webClient.Headers.Add("Authorization","Client-ID myactualclientidhere");
            webClient.Headers.Add("User-Agent", Application.platform + ":" + Application.identifier + ":" + Application.version + " someappspecificinfohere");
            webClient.Headers.Add("X-Mashape-Key", "myactualmashapekeyhere");
            imageAsByteArrayFromPNG = texture.EncodeToPNG();
            string imageAsBase64String = Convert.ToBase64String(imageAsByteArrayFromPNG);
            NameValueCollection uploadValues = new NameValueCollection();
            uploadValues.Add("image", imageAsBase64String);
            uploadValues.Add("type", "base64");
            webClient.UploadValues("https://imgur-apiv3.p.mashape.com/3/image", uploadValues);
            byte[] imgurResponse = webClient.UploadValues("https://api.imgur.com/3/image.xml", uploadValues);
            Debug.Log(XDocument.Load(new MemoryStream(imgurResponse)));
            yield return imgurResponse;
        }

TL;DR Anyone who was able to use UnityWebRequest to successfully make a post and receive a response has an example to share?

Why are you using Put in your second code, rather than Post?
The request headers should be setup like you do in second sample, but you should use Post in it, not put.
