Правя GET с помощта на jQuery. Методът, който извиквам, е в моя контролер (MVC-4) и методът има 1 параметър.
Имам своите данни и знам, че низът с данни е валиден. Мога също да кажа, че публикуваните от мен данни са валидни JSON, като това:
{
"txid": "051e30921f2886595ad9f22401437f10a77635c21b33b0e9e0aaefd52488e234-000"
}
Въпреки това, когато направя командата GET, моят параметър на контролера е нулев. Във FireBug виждам, че е извършено повикване и получавам следната грешка:
"NetworkError: 500 Internal Server Error - http://localhost:52705/Home/GetInformationAboutTransaction?{%22txid%22:%22051e30921f2886595ad9f22401437f10a77635c21b33b0e9e0aaefd52488e234-000%22}"
И с точка на прекъсване в контролера, мога да стартирам кода на контролера с моя нулев параметър.
Не съм променил нищо в стандартния MVC проект (без маршрутизиране, без промени в global.asax).
Код:
var txId = $('#infoTransactionTxIdBox').val();
if (txId) {
alert(txId);
$.ajax({
type: "GET",
datatype: "json",
contentType: "application/json; charset=utf-8",
data: '{"txid":"' + txId + '"}',
url: "/Home/GetInformationAboutTransaction",
success: function (data) {
$('#infoAboutTransactionLbl').text(data);
}
});
} else {
$('#infoAboutTransactionLbl').text('You need to enter a transaction id');
}
Контролерът:
[HttpGet]
public JsonResult GetInformationAboutTransaction(string txid)
{
var rawTransaction = _baseBtcConnector.GetRawTransaction(txid);
var infoAboutTransaction = _baseBtcConnector.DecodeRawTransaction(rawTransaction);
return Json(infoAboutTransaction);
}
