I am passing a list of objects to my API in C #. When the list size is smaller, everything happens as it should. When the list is a bit larger the list comes empty in my API.
When the list is smaller I get the expected result:
HoweverwhenIsendthislist:
Igetthisresult:
Could someone explain to me why and how to solve this problem?
You can modify the httpRuntime element in the file web.config by adding the following attribute. This should resolve the problem of having object null when executing POST.
// limite para o buffer de fluxo de entrada, em kilobytes
<httpRuntime maxRequestLength="2147483647" />
However, you may have problems with request filtering introduced in version 7.0 of IIS. More specifically (my translation):
When request filtering blocks an HTTP request, IIS 7 will return an HTTP 404 error to the client and register the HTTP status with a unique substatus that identifies the reason why the request was denied.
+----------------+------------------------------+
| HTTP Substatus | Descrição |
+----------------+------------------------------+
| 404.5 | Sequência URL Negada |
| 404.6 | Verbo Negado |
| 404.7 | Extensão de arquivo Negada |
| ... | |
To resolve this limitation, you can modify the <requestLimits> element within the web.config
// limita o POST para 10MB, query string para 256 chars, url para 1024 chars
<requestLimits maxQueryString="256" maxUrl="1024" maxAllowedContentLength="102400000" />
Try to send this:
public JsonResult PdfSellout(List<SellOut> sellout)
{
var lista = buscarLista();
var jsonResult = Json(lista, JsonRequestBehavior.AllowGet);
jsonResult.MaxJsonLength = int.MaxValue;
return jsonResult;
}
Edit: The above method is for reply, for sending files use the following:
var httpClient = new HttpClient();
httpClient.DefaultRequestHeaders.TransferEncodingChunked = true;
var content = new CompressedContent(new StreamContent(new FileStream("c:\big-json-file.json",FileMode.Open)),"UTF8");
var response = httpClient.PostAsync("http://example.org/", content).Result;
