HttpClient.SendAsync или PostAsync выдает ошибку ниже.
System.Net.Http.HttpRequestException: An error occurred while sending the request. ---> System.Exception: The text associated with this error code could not be found.
'': Invalid characters found.

Вот код C #:
var address = new AddressModel()
{
CommunicationId = "email@domain.com",
......
};
var stringContent = new StringContent(JsonConvert.SerializeObject(address), Encoding.UTF8, "application/json");
HttpClient client = new HttpClient();
client.DefaultRequestHeaders
.Accept
.Add(new MediaTypeWithQualityHeaderValue("application/json"));//ACCEPT header
client.DefaultRequestHeaders.Add("Cookie", AuthCookie);
client.DefaultRequestHeaders.Add("X-Requested-With", "X");
HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Post, url)
{
Content = stringContent//CONTENT-TYPE header
};
try
{
//Failing on this Line.
responseMessage = await client.SendAsync(request);
if (responseMessage.IsSuccessStatusCode)
{
var responseContent = await responseMessage.Content.ReadAsStringAsync();
}
}
catch (Exception ex)
{
//
}
На самом деле, вызов Post был успешным, и был создан код ответа 201, если мы наблюдаем его в fiddler.но ответ Json, возвращаемый после вызова, вызывает ошибку, и поэтому PostAsync не может подготовить объект HttpResponseMessage.
Я не вижу проблем с ответом JSON, вставленным ниже, который мог бы вызвать - найдены недопустимые символы.
Предоставление необработанного запроса и ответа.
