    Hi,

    Thanks. Could you upgrade your Abp NuGet packages to 6.4 and redeploy your app to see if it fixes the problem. I think you are facing a similar issue to https://github.com/aspnetboilerplate/aspnetboilerplate/pull/6165

    Hi,

    We upgraded the nuget package to 6.4 and in that process we faced lot of issues. So we upgraded lot of other dlls as well and that lead to one more issue as follows:

    Basically what we are trying to do is fetch data from URL and showing at our end. We are passing URL in following CreateProxyHttpRequest and getting the data without any issue in version 5.10 but getting above attached image error after upgrading to 6.4.

    var request = HttpContext.CreateProxyHttpRequest(new Uri(_url));
    var response = await _client.SendAsync(request, HttpCompletionOption.ResponseHeadersRead, HttpContext.RequestAborted);
    await HttpContext.CopyProxyHttpResponse(response);
    

    Following is the code which we are using for Proxy request:

    `public static class ProxyRequest { public static HttpRequestMessage CreateProxyHttpRequest(this HttpContext context, Uri uri) { var request = context.Request;

        var requestMessage = new HttpRequestMessage();
        var requestMethod = request.Method;
        if (!HttpMethods.IsGet(requestMethod) &&
            !HttpMethods.IsHead(requestMethod) &&
            !HttpMethods.IsDelete(requestMethod) &&
            !HttpMethods.IsTrace(requestMethod))
        {
            var streamContent = new StreamContent(request.Body);
            requestMessage.Content = streamContent;
        }
    
        // Copy the request headers
        foreach (var header in request.Headers)
        {
            if (!requestMessage.Headers.TryAddWithoutValidation(header.Key, header.Value.ToArray()) && requestMessage.Content != null)
            {
                requestMessage.Content?.Headers.TryAddWithoutValidation(header.Key, header.Value.ToArray());
            }
        }
    
        requestMessage.Headers.Host = uri.Authority;
        requestMessage.RequestUri = uri;
        requestMessage.Method = new HttpMethod(request.Method);
    
        return requestMessage;
    }
    public static async Task CopyProxyHttpResponse(this HttpContext context, HttpResponseMessage responseMessage)
    {
        if (responseMessage == null)
        {
            throw new ArgumentNullException(nameof(responseMessage));
        }
    
        var response = context.Response;
    
        response.StatusCode = (int)responseMessage.StatusCode;
        foreach (var header in responseMessage.Headers)
        {
            response.Headers[header.Key] = header.Value.ToArray();
        }
    
        foreach (var header in responseMessage.Content.Headers)
        {
            response.Headers[header.Key] = header.Value.ToArray();
        }
    
        // SendAsync removes chunking from the response. This removes the header so it doesn't expect a chunked response.
        response.Headers.Remove("transfer-encoding");
    
        using (var responseStream = await responseMessage.Content.ReadAsStreamAsync())
        {
            await responseStream.CopyToAsync(response.Body, 1000000, context.RequestAborted);
        }
    }
    

    }`

    Hi @huntethan89

    This seems like an error related to ASP.NET Core. As I can see, there are many reasons for this error, see https://stackoverflow.com/questions/58215104/whats-the-neterr-http2-protocol-error-about.

    • Have you solved this issue ?
    • Does that happen on development time ?

    Hi,

    Issue is not resolved yet. We tried with ASP.net Core 5.0 application without ABP and tested there with ASPNETCore.Proxy. It is working fine there but when using with ABP net zero it was not working.

    Hi,

    Could you try the solution below;

    1. Add [WrapResult(WrapOnSuccess = false, WrapOnError = false)] to related action method
    2. Add AddProxies as shown below;

    Hi,

    Here is the message;

    You were right, it doesn't work for the Index action but it works for ProxyToPHPServer. Is that enough for you or do you want us to investigate it deeper ?

    Hi,

    Our work is specifically with the action method. If you can resolve the issue for the Index action method, that would be helpful.

    Hi @huntethan89

    We are looking into this but couldn't find the reason yet. Could you share why do you want to use the result type Task<IActionResult> instead of Task ? We can consider your use case while checking the issue.

    Hi, We want to use Task&lt;IActionResult> because the function returns view as in most of the conditions. I am attaching the actual function. I hope it will help you to understand the case.

    <br> <br> public async Task<IActionResult> Index(string SclGuid, string SubGuid, string Categoryid, string bookid, string title, string bookcode, string toc, string QuotID, string QuoteCategoryid, bool IsRead) { if (QuotID != null && QuoteCategoryid != null && Categoryid == null) { Categoryid = QuoteCategoryid; } bool isTokenAccessExpired = false; var AccessTokenId = ""; bool isQuoteSetting = false; // isQuoteSetting = await isQuoteData(SubGuid); //** This id done for user Access when user login from Openlightbox.com *// var SubsId = SubGuid.Split("|"); if (SubsId.Length > 1) { try { AccessTokenId = HttpContext.Session.GetString("AccessTokenId").ToString(); isTokenAccessExpired = AccessTokenId == null ? true : false; } catch { return Redirect("https://openlightbox.com"); } } int? subscriptionId = await _entity_SchoolSubscriptionsMaster.GetAll() .Where(x => x.SubscriptionGuid_Id == SubsId[0]).Select(x => x.SubscriptionId_FK) .FirstOrDefaultAsync(); bool IsForTeacher = await _entity_SubscriptionMaster.GetAll().WhereIf(subscriptionId != null, x => x.Id == subscriptionId).Select(x => x.IsForTeacher).FirstOrDefaultAsync(); if (IsForTeacher && !User.Identity.IsAuthenticated) { return Redirect("/Account/Login?returnUrl=" + HttpContext.Request.Path.Value); } if (!isTokenAccessExpired) { TASubscriptionModel model = new TASubscriptionModel(); // model.IsQuoteSetting = isQuoteSetting; model.IsTeacherView = IsForTeacher; AdminQuoteSettingController quoteSetting = await QuoteSetting(SubGuid); if (quoteSetting == null) model.IsQuoteSetting = false; else { isQuoteSetting = model.IsQuoteSetting = true; model.Discount = quoteSetting.Discount; var QuoteInfo = await _entity_QuoteInfo.GetAll() .Where(x => x.QuoteSettingIDFK == quoteSetting.Id) .WhereIf(QuotID != null && QuotID.Trim() != "", x => x.Id == Convert.ToInt32(QuotID)) .FirstOrDefaultAsync(); Tuple<int, Double> BookCountPrice = await GetBookCountPrice(model.Discount, QuoteInfo == null ? 0 : QuoteInfo.Id); model.BookCount = BookCountPrice.Item1; model.BookQuoteAmount = BookCountPrice.Item2.ToString(); } try { string ActiveSubscriptionMessage = await _taSubscriptionAppService.IsSubscriptionActive(SubsId[0], isQuoteSetting); if (ActiveSubscriptionMessage == "" || isQuoteSetting == true) { if (ActiveSubscriptionMessage != "") { model.SubscriptionStatus = "Past"; } if ((Categoryid == null || Categoryid.Contains("Filter-") == true) && bookid == null) { if (SubsId[0] != null) { //model.sliderList = await _taSubscriptionAppService.GetSlidersinfo(SubGuid); //model.tasubscriptionBooksInfo = await _taSubscriptionAppService.GetBookDataForTASubscription(SclGuid, SubGuid, "", "", "%", "-", "-", "-", 1, false, false, false); model.advanceSearchGrades = await _taSubscriptionAppService.GetSubscriptionAdvanceFilters(SubsId[0], isQuoteSetting); model.SchoolGuidId = SclGuid; model.SubscriptionGuidId = SubsId[0]; model.bookResources = await _taSubscriptionAppService.GetBookResourcesIcons(SclGuid, SubsId[0]); model.isFilterActive = false; if (Categoryid != null) { string FilterToken = Categoryid.Split("Filter-")[1]; if (FilterToken.Trim() != "") { HttpContext.Session.Clear(); if (!string.IsNullOrWhiteSpace(AccessTokenId)) { HttpContext.Session.SetString("AccessTokenId", AccessTokenId); } model.ActivefilterValues = await _taSubscriptionAppService.GetActiveFiltersdata(FilterToken); } } } return View(model); } else { var url = HttpContext.Request.GetDisplayUrl(); await TAsubscriptionBookView(Convert.ToInt32(Categoryid), Convert.ToInt32(bookid), SclGuid, SubsId[0], title, bookcode, toc, url, isQuoteSetting, QuotID, IsRead); model.ValidsubscriptionMsg = ActiveSubscriptionMessage; return View(model); } } else { System.Text.RegularExpressions.Match match = Regex.Match(ActiveSubscriptionMessage, @"[A-Za-z]{3}\s\d{2},\s\d{4}"); string date = match.Value; if (!string.IsNullOrEmpty(date)) { var dateTime = CommonClass.GlobelDateFormat(System.DateTime.ParseExact(date, "MMM dd, yyyy", CultureInfo.CurrentCulture)); //--- Future if (dateTime > CommonClass.GlobelDateFormat(System.DateTime.Now.Date)) { model.SubscriptionStatus = "Future"; model.booksThumbnailsData = await _taSubscriptionAppService.GetBooksCoverImagesBySubscription(SubGuid); } else if (dateTime < CommonClass.GlobelDateFormat(System.DateTime.Now.Date)) { model.SubscriptionStatus = "Past"; } model.SubscriptionStatusDate = dateTime; } if (model.SubscriptionStatus == "Past") model.ValidsubscriptionMsg = Convert.ToDateTime(model.SubscriptionStatusDate).ToString("MMMM dd, yyyy") + "| "; else model.ValidsubscriptionMsg = ActiveSubscriptionMessage; return View(model); } } catch (Exception ex) { CommonClass.Writelogs1("Error: " + ex.Message); return View(model); } } else { return Redirect("https://openlightbox.com"); } }


    the function `TAsubscriptionBookView` is being called in the above-mentioned index function to return the proxy URL.

    Hi @huntethan89,

    Could you try this solution?

    Add wrap attribute to the class.

    [WrapResult(WrapOnSuccess = false, WrapOnError = false)]
    public class ProxyController : ProjectDemoControllerBase
    {
        public async Task<IActionResult> Index()
        {
            var url = "the-url";
    
            // Ensure the response is fully handled by HttpProxyAsync
            await this.HttpProxyAsync(url);
            
            // Return a blank result to avoid modifying the response after it has started
            return new EmptyResult();
        }
    
        public Task ProxyToPHPServer()
        {
            return this.HttpProxyAsync("url");
