Using Visual Studio 2010, I’m calling SOAP webservices and keep getting the error «Error in deserializing body of reply message«.

I call the WS method like this:

    wsConfig.config_pttClient client = new wsConfig.config_pttClient();
    wsConfig.getConfigInput gci = new wsConfig.getConfigInput();
    wsConfig.getConfigOutput gco = new wsConfig.getConfigOutput();

    gco = client.getConfig(gci); // the exception is thrown here

The method doesn’t need input data: I test it using SoapUI and it works fine. Using fiddler, I see the call is made and the answer with all the data correct.

After researching for a while, I tried to alter the readerQuotas like maxStringContentLength, maxDepth etc. inside the xsd but no luck.

I got a little workaround for the getConfig method though: when I alter the Reference.cs file and change the System.DateTime variable types to string, it works fine but then I need to invoke a setConfig method, and that alteration brings another problem… Also, I’ve read that altering the webservice contract isn’t a good practice.

I’ve been looking for a solution for a while now and here are some places I checked: this, this, this or this.

Can someone help?
Thanks

Есть сервис расположенный по адресу https://ххх.рф (основной), у него есть API с маршрутом до него — https://ххх.рф/api/TelegramBot/AcceptReplyMessageBot:

[HttpPost("AcceptReplyMessageBot")]
        public async Task<IActionResult> AcceptReplyMessageBot([FromBody] MessageData messageData)
        {
            Friend friend;
        ResponseMessageData responseMessage;
        string jsonResponse;
        string numberPhone = messageData.PhoneNumber != null ? ServicePhoneNumber.LeaveOnlyNumbers(messageData.PhoneNumber) : null;
        if (numberPhone != null && numberPhone.Length > 10)
        {
            friend = _serviceFriends.FindUserByPhoneNumber(numberPhone);
        }
        else
        {
            responseMessage = new ResponseMessageData { Status = "Invalid phone number" };
            return Ok(responseMessage);
        }

        string textQrCode;
        Byte[] byteCode = null;

        if (friend != null) {
            textQrCode = friend.TextQRcode;
        }
        else
        {
            responseMessage = new ResponseMessageData { Status = "Not found" };
            return Ok(responseMessage);
        }

        if(friend.ByteQrcode != null)
        {
            byteCode = friend.ByteQrcode;
        }

        if(textQrCode != null && byteCode != null)
        {
            responseMessage = new ResponseMessageData { PhoneNumber = friend.Telephone, TextMessage = textQrCode, ByteQrcode = byteCode };
        }
        else if (textQrCode != null)
        {
            responseMessage = new ResponseMessageData { PhoneNumber = friend.Telephone, TextMessage = textQrCode};
        }
        else
        {
            responseMessage = new ResponseMessageData { TextMessage = "Участнику с данным номером телефона не присвоен QR-код!" };
        }

        return Ok(responseMessage);
        }

Есть другой микро сервис по адресу https://messanger.ххх.рф (TLmessenger), который отправляет на вышеописанный основной сервис POST запросы и обрабатывает от него ответы:

                    messageNumberPhone = ServicePhoneNumber.LeaveOnlyNumbers(message.Text);

                    if (messageNumberPhone.Length < 11 || messageNumberPhone.Length > 12)
                    {

Пробовал отправлять на каждый из этих контроллеров обоих сервисов POST запросы через Postman — все отрабатывает норм.
Проверил работает ли 2-ой сервис (бот TLmessenger) отдельно без отправки запросов на основной — работает.
Добавил отправку запросов из бота TLmessenger на основной сервис — TLmessenger перестал работать.

Далее запустил первый (основной) сервис у себя на локально через ngrok, а 2-му (боту TLmessenger) прописал адрес url на который нужно слать запросы на 1-ый, который сформировал ngrok. Залил 2-ой (бота TLmessenger) на хостинг, в итоге TLmessenger сообщения из телеграмма получает, обрабатывает, отправляет POST запрос на основной сервис, основной сервис получает этот запрос отрабатывает и отправляет ответ, но TLmessenger не отвечает, по ходу не может обработать ответ.

Попробовал запустил первый (основной) сервис у себя на локально через ngrok. 2-ой (бота TLmessenger) запустил в режиме отладки на другом ПК и отправил запрос через swagger, в итоге TLmessenger сообщение из swagger получает, обрабатывает, отправляет POST запрос на основной сервис (запущенный на ngrok), основной сервис получает этот запрос отрабатывает и отправляет ответ, TLmessenger ответ получает, но когда пытается вернуть его

string jsonResponseData = await PostRequestHttpAsync(url, jsonRequest);
                ResponseMessageData responseData = JsonSerializer.Deserialize<ResponseMessageData>(jsonResponseData);
                string str = responseData.Status;
                return Ok(str);

получаю ошибку:

204 Undocumented Response headers  date: Thu30 Sep 2021 04:58:28 GMT   server: Microsoft-IIS/10.0   x-powered-by: ASP.NET

Не пойму в чем проблема.

Скрины ответа полученного от основного сервиса из отладчика:

Запустил оба сервиса на одном хосте, но на разных портах с помощью Kestral. При тестировании выдало следующею ошибку:

С основного сервиса у меня уходит ответ следующего вида:

Я пишу консольный WCF-клиент для одного WCF-WebService. При вызове службы я получаю ошибку при десериализации тела запроса:

Ошибка десериализации тела ответного сообщения для операции «GetProfiles»

Profile[] profiles = mediaClient.GetProfiles(); // throw excpetion

Я уже смотрел запросы и ответы со сниффером, и это нормально! WebService отправил «200 OK». Если у меня есть небольшой ответ от WebService, ошибок и исключений не будет! У меня нет кода WebService. Что мне делать?

Я переписываю свой код. Теперь у меня есть:

    string soapRequest = "<s:Envelope xmlns:s="http://www.w3.org/2003/05/soap-envelope">" +
                                 "<s:Header>" +
                                 "</s:Header>" +
                                 "<s:Body xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">" +

                                 "</s:Envelope>";


XmlReader envelopeReader = XmlReader.Create(new StringReader(soapRequest));

Message requestMsg = Message.CreateMessage(envelopeReader, int.MaxValue, MessageVersion.Soap12);

Message responseMsg = null;

IChannelFactory<IRequestChannel> channelFactory = binding.BuildChannelFactory<IRequestChannel>();
channelFactory.Open();

IRequestChannel channel = channelFactory.CreateChannel(MediaEndPointAddress);
channel.Open();

responseMsg = channel.Request(requestMsg);
Console.WriteLine(responseMsg.ToString());

Последнее сообщение возврата строки «Ошибка чтения тела: System.Xml.XmlException:» «содержит недопустимые байты UTF8….}».

WebService отправляет байты без ut8, но указывает «UTF-8» в заголовке.
Что я могу сделать?

I am using third party service to get data using rest API. But sometimes it return more than 6 MB data. They don’t have API to provide data in chunks. I am already using future method to increase heap size limit to 12 MB.

With below code, I am facing heap size error at the time of de-serialization of data. I have also emphasised that line where I am getting error.

Столкнулся с ошибкой при десериализации ответа от api.vk.com.
