I am using dataUrl to populate my dropdown in form edit of jqGrid, but i am not getting any response from server. what am i missing? fiddler shows no error
editoptions: {
dataUrl: "CurrencySetting.aspx/GetDet",
buildSelect: function (response) {
alert(response.responseText);
var data = typeof response === "string" ?
$.parseJSON(response.responseText) : response;
s = "<select>";
s += '<option value="0">------</option>';
$.each(data, function () {
s += '<option value="1">' + this.CurrencyCd +
'</option>';
});
return s + "</select>";
}
}
server code:
public static string GetDet()
{
SysDataContext db = new SysDataContext();
var query = (from SC in db.SysCurrencySettings
select new
{
SC.CurrencyCd
}).ToList();
return JsonConvert.SerializeObject(query);
}

I am doing post request to an api !
string url = "http://xxx.xxx.xx.xx/api/QMn/Create";
var client = new HttpClient();
client.BaseAddress = new Uri(url);
// client.Headers.ContentType = new MediaTypeHeaderValue("application/json");
StringContent content = new StringContent(JsonConvert.SerializeObject(DataToSave), Encoding.UTF8, "application/json");
HttpResponseMessage response = await client.PostAsync(url, content);
var result = await response.Content.ReadAsStringAsync();
the Api recieving request is this :
public void Create([FromBody] IEnumerable<QMSRejection> DataToSave)
{
try
{
_QMSRejection.Create(DataToSave);
}
catch (Exception ex)
{
Console.WriteLine(ex);
}
}
I am receiving this error I am not able to understand why ?

Do I have to pass headers but I only require to pass body !
I solved the issue the error was from API Side and not client side ! There were validations in the API that was causing it to give such errors !
I have a xamarin app that pull data from a webAPI. I check api address so many times and i am sure it is correct. When i debug my code i have 404 not found error from server. However when i copy and paste the URL to browser i have expected result. I couldn't figure out why my app return 404.
My Method:
public async Task<ICustomerType> GetById(int id)
{
string _token;
if (App.Current.Properties.ContainsKey("token"))
{
_token = (string)App.Current.Properties["token"];
}
else
{ _token = null; }
var webApiResponse =
_connector.PostAsync(
"api/Customer/get/id/" + id,
string.Empty, _token).Result;
var response = webApiResponse.Result.ToString();
var jObjectResponse = JObject.Parse(response);
ICustomerType customerTypeObj = null;
return customerTypeObj;
}
My bridge method to HttpClient's PostAsync method:
private async Task<TResponse> PostAsync(string requestPath, string
jsonContent, bool getToken, string token)
{
HttpClient client = new HttpClient();
client.BaseAddress = new Uri(_apiUrl);
client.DefaultRequestHeaders.Accept.Clear();
var contentType = new MediaTypeWithQualityHeaderValue("application/json");
client.DefaultRequestHeaders.Accept.Add(contentType);
if (getToken)
{
token = GetApiTokenAsync().Result;
}
if (!string.IsNullOrEmpty(token))
{
client.DefaultRequestHeaders.Add("Authorization", "Bearer " + token);
}
var httpContent = new StringContent(jsonContent, Encoding.UTF8, "application/json");
var response = client.PostAsync(requestPath, httpContent).Result;
var jsonData = await response.Content.ReadAsStringAsync();
return JsonConvert.DeserializeObject<TResponse>(jsonData);
}
Token: Correct
API Url: Correct(I check "/" signs from debug output.They are well placed. My Api like:
https://MyApi.net/api/Personel/get/id/1)
My Error:

your method verb in API is "GET" but you used "POST" in the client So in browser works because browser call "GET", but in the client doesn't work.
instead of :
var webApiResponse =
_connector.PostAsync(
"api/Customer/get/id/" + id,
string.Empty, _token).Result;
use :
var webApiResponse =
_connector.GetAsync(
"api/Customer/get/id/" + id,
string.Empty, _token).Result;
Getting error while posting data to sql using .net Web API in xamarin.forms

this is my code to post data
T returnResult = default(T);
HttpClient client = null;
try
{
client = new HttpClient();
client.BaseAddress = new Uri(HostName);
client.DefaultRequestHeaders.Add("Accept", "application/json");
client.Timeout = new TimeSpan(0, 0, 15);
HttpResponseMessage result = null;
StringContent data = null;
if (content != null)
// data = new StringContent(JsonConvert.SerializeObject(content), UTF8Encoding.UTF8, "application/json");
data = new StringContent(JsonConvert.SerializeObject(content), Encoding.UTF8, "application/json");
if (method == HttpMethod.Get)
result = await client.GetAsync(endpoint);
if (method == HttpMethod.Put)
result = await client.PutAsync(endpoint, data);
if (method == HttpMethod.Delete)
result = await client.DeleteAsync(endpoint);
if (method == HttpMethod.Post)
result = await client.PostAsync(endpoint, data);
if (result != null)
{
if (result.IsSuccessStatusCode
&& result.StatusCode == System.Net.HttpStatusCode.OK)
{
var json = result.Content.ReadAsStringAsync().Result;
returnResult = JsonConvert.DeserializeObject<T>(json);
}
}
where should be the problem ?. My API is working fine and it is enabled CORS
Here is an example of how I am using PostAsync in my code, I think the error 'No Content' is referring on you are not sending anything to the server maybe? I hope this example helps:
public async Task<bool> PostAppointmet(AppointmentEntity anAppointment)
{
try{
HttpClient client = new HttpClient();
client.DefaultRequestHeaders.Add("Authorization", "Bearer " + App.apiToken);
const string resourceUri = ApiBaseAddress + "/citas";
string postBody = JsonConvert.SerializeObject(anAppointment);
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
HttpResponseMessage response = await client.PostAsync (resourceUri, new StringContent (postBody, Encoding.UTF8, "application/json"));
if (response.IsSuccessStatusCode) {
return true;
}
return false;
}
catch{
return false;
}
}
Where AppointmentEntity is my Model:
public class AppointmentEntity
{
public int doctor { get; set; }
public PatientEntity paciente { get; set; }
public DateEntity cita { get; set; }...
}
Try to use like this
var task = client.PostAsync(endpoint,content:data);
Recently I found very strange behavior of IE8/9 when sending XHR data. I'd like to ask you if you have ever seen such behavior? Is it IE bug? How can I protect my server from "empty" request generated by IE? Here are more details:
I found out that when your page tries to send XHR data and JavaScript freezes or lags browser, IE lags sending POST data to server. To make it clear, here are steps to reproduce:
Create simple server which dumps POSTs received. I've used Node.JS for tests. You can find corresponding codes at the bottom of the post.
Open localhost:8080 in IE, open debug window and start debuging scripts with breakpoint set in line 51 of file localhost:8080
Hit Send by JQuery. You should have your javascript waiting on the breakpoint and server logged message:
--------------------------------------
14:04:19
REQUEST: /
HTTP HEADER:
accept = text/html, application/xhtml+xml, */*
accept-language = pl-PL
user-agent = Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; WOW64; Trident/5.0)
accept-encoding = gzip, deflate
host = localhost:8080
connection = Keep-Alive
--------------------------------------
14:04:35
REQUEST: /test
HTTP HEADER:
accept = */*
content-type = application/json
x-requested-with = XMLHttpRequest
referer = http://localhost:8080/
accept-language = pl
accept-encoding = gzip, deflate
user-agent = Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; WOW64; Trident/5.0)
host = localhost:8080
content-length = 24
connection = Keep-Alive
cache-control = no-cache
When you release JavaScript from the breakpoint server reports incoming data by new line:
POST: {"data1":10,"data2":123}
I've done the same test on Opera 12.15 and Chrome 27.0.1453.94 m and, as expected, POST data are sent immediately.

Code for node.js server:
var http = require('http');
var qs = require('querystring');
var fs = require('fs');
http.createServer(function (req, res) {
console.log('--------------------------------------');
console.log(new Date().toLocaleTimeString());
console.log('REQUEST: ' + req.url);
console.log('HTTP HEADER: ');
for (var header in req.headers) {
console.log(' ' + header + ' = ' + req.headers[header]);
}
switch (req.method) {
case 'POST':
var body = '';
req.on('data', function (data) {
body += data;
});
req.on('end', function() {
console.log('POST: ' + body);
});
res.writeHead(200, {'Content-type': 'application/json'});
res.end(JSON.stringify({ succeeded: true, value: 'Hello world!' }));
break;
case 'GET':
fs.readFile('./servertest.html', function (err, data) {
if (err) {
throw err;
}
res.writeHeader(200, {'Content-type': 'text/html'});
res.end(data);
});
break;
}
}).listen(8080, 'localhost');
console.log('listening on localhost:8080');
Code for servertest.html:
<!DOCTYPE html>
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
</head>
<body>
<button onclick="send()">Send by JQuery</button>
<button onclick="sendXHR()">Send by XHR</button>
</body>
<script type="text/javascript">
var _xhr;
function sendXHR() {
_xhr = new XMLHttpRequest();
new XHRStateChangeListener();
var url = '/testXHR';
var method = 'POST';
_xhr.open(method, url);
_xhr.setRequestHeader("Content-Type", "application/json");
_xhr.send(JSON.stringify({test: 'this is a test', aoawiejf:23423}));
}
function XHRStateChangeListener() {
callback = function() {
var msg;
if (_xhr.readyState == 4 && /200|304/.test(_xhr.status)) {
alert('ready: ' + _xhr.responseText);
}
};
_xhr.onreadystatechange = callback;
}
function send() {
$.ajax({
url: '/test',
type: 'POST',
data: JSON.stringify({data1: 10, data2: 123}),
contentType: 'application/json',
error: function(xhr, status, err) {
alert('Error: ' + err + '\nStatus: ' + status);
},
success: function (data) {
alert('succeeded! data: ' + data);
}
});
}
</script>
</html>
You are using sync-mode, right is async-mode:
replace
_xhr.open(method, url);
by
_xhr.open(method, url, true);//Async mode
Note: Remember "onreadystatechange" is only for async-mode
the problem may also be in this function (just a guess):
JSON.stringify
try sending empty data, ie: data:""
Can somebody help me how to post an array of type long to a WebApi.
I think I have to use PostAsync from HttpClient, but I am not sure how to put array to HttpContent.
This is my controller.
[HttpPost]
[Authorize]
public void UpdateBatchesToReadyToShip(long[] batchIds)
{
// process request
}
And this is how I am trying to consume API
var buffer = Encoding.ASCII.GetBytes("username:password");
var authHeader = new AuthenticationHeaderValue("Basic", Convert.ToBase64String(buffer));
client.DefaultRequestHeaders.Authorization = authHeader;
var arr = new long[3];
arr[0] = 10;
arr[1] = 12;
arr[2] = 13;
HttpContent content = new StringContent(string.Join(",", from i in arr select i.ToString()));
var task = client.PostAsync("https://<uri>/api/orderprocessing/UpdateBatchesToReadyToShip",content:content);
if (task.Result.StatusCode == HttpStatusCode.Unauthorized)
{
Console.WriteLine("wrong credentials");
}
else
{
//task.Result.EnsureSuccessStatusCode();
HttpResponseMessage message = task.Result;
if (message.IsSuccessStatusCode)
{
var details = message.Content.ReadAsStringAsync().Result;
Console.Write(details);
}
}
And I am getting this exception
{StatusCode: 500, ReasonPhrase: 'Internal Server Error', Version: 1.1, Content: System.Net.Http.StreamContent, Headers:
{
Pragma: no-cache
Cache-Control: no-cache

X-Powered-By: ASP.NET
Content-Length: 1060

}}
Instead of using StringContent, you can use ObjectContent:
var content = new ObjectContent<long[]>(arr, new JsonMediaTypeFormatter());
var task = client.PostAsync(
"https://<uri>/api/orderprocessing/UpdateBatchesToReadyToShip",
content:content);
