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();
        }
    }

CodePudding user response：

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
}
