How do I get upload progress for web request

Question

Tried to use progressMessageHandler from Net.Http.Handlers namespace but I got

The type or namespace name 'Handlers' does not exist in the namespace 'System.Net.Http' (are you missing an assembly reference?)

Things I have tried:

Visual studio's Add reference. not working cause unity download System.Net.Http dll and put it to unity dll's not working too
update System.Net.Http from nuget

My current code is:

public static async Task<string> Upload(string uri, string pathFile)
    {

        byte[] bytes = System.IO.File.ReadAllBytes(pathFile);

        using (var content = new ByteArrayContent(bytes))
        {
            content.Headers.ContentType = new MediaTypeHeaderValue("*/*");

            //Send it
            var response = await nftClient.PostAsync(uri, content);
            response.EnsureSuccessStatusCode();
            Stream responseStream = await response.Content.ReadAsStreamAsync();
            StreamReader reader = new StreamReader(responseStream);
            return reader.ReadToEnd();
        }
    }

Sounds like an [xy problem](https://meta.stackexchange.com/a/66378/405359). What are you trying to use that namespace for? — Ruzihm, Mar 03 '22 at 17:57
for progressMessageHandler , I have HTTP ClIENT to Upload my file to server . And Show my user Upload progress — ArIaNFury, Mar 03 '22 at 18:22
handler.HttpSendProgress += (s, e) => { float prog = (float)e.BytesTransferred / (float)bytes.Length; prog = prog > 1 ? 1 : prog; print(prog); }; — ArIaNFury, Mar 03 '22 at 18:23

I would just use UnityWebRequest and use uploadProgress to update the progress:

UnityWebRequest uwr;

void Start()
{
    StartCoroutine(PutRequest("http:///www.yoururl.com"));
    StartCoroutine(UploadProgressCoroutine());
}

IEnumerator PutRequest(string url)
{
    byte[] dataToPut = System.Text.Encoding.UTF8.GetBytes("Hello, This is a test");
    uwr = UnityWebRequest.Put(url, dataToPut);
    yield return uwr.SendWebRequest();

    if (uwr.isNetworkError)
    {
        Debug.Log("Error While Sending: " + uwr.error);
    }
    else
    {
        Debug.Log("Received: " + uwr.downloadHandler.text);
    }
}

IEnumerator UploadProgressCoroutine()
{
    while (!uwr.isDone)
    {
        HandleProgress(uwr.uploadProgress);
        yield return null;
    }
}

void HandleProgress(float currentProgress)
{
    // currentProgress is value between 0 and 1
}

Based on Programmer's code here.

Or for your specific use case, you will need to create your own UnityWebRequest to get the headers and data the way your server expects:

UnityWebRequest uwr;

void Start()
{
    StartCoroutine(PostRequest("http:///www.yoururl.com", "/file/path/here"));
    StartCoroutine(UploadProgressCoroutine());
}

IEnumerator PostRequest(string url, string filePath)
{
    byte[] dataToPost = System.IO.File.ReadAllBytes(filePath);

    uwr = new UnityWebRequest(url, "POST", new DownloadHandlerBuffer(),
            new UploadHandlerRaw(dataToPost));

    uwr.SetRequestHeader("Content-Type", "*/*");
    uwr.SetRequestHeader("Accept", "application/json"); 
    uwr.SetRequestHeader("Authorization", "Bearer " + apiToken);

    yield return uwr.SendWebRequest();

    if (uwr.isNetworkError)
    {
        Debug.Log("Error While Sending: " + uwr.error);
    }
    else
    {
        Debug.Log("Received: " + uwr.downloadHandler.text);
    }
}

IEnumerator UploadProgressCoroutine()
{
    while (!uwr.isDone)
    {
        HandleProgress(uwr.uploadProgress);
        yield return null;
    }
}

void HandleProgress(float currentProgress)
{
    // currentProgress is value between 0 and 1
}

@ArIaNFury "Created other problems" doesn't describe what happened or didnt happen, only that it didn't meet your expectation. Please be more descriptive. Including your code was helpful. See my edit. — Ruzihm, Mar 03 '22 at 20:07
it works fine but there is problem I cant get information from api Debug.Log("Received: " + uwr.downloadHandler.text); give me wrong info how can put DefaultRequestHeaders ? such nftClient.DefaultRequestHeaders.Add("Accept", "application/json"); and nftClient.DefaultRequestHeaders.Add("Authorization", "Bearer " + apiToken); — ArIaNFury, Mar 03 '22 at 20:24
amazing thanks. I just add uwr.SetRequestHeader and worked as should be — ArIaNFury, Mar 03 '22 at 20:31
