I need a C# code that will trigger a nprinting task. On our server we are not allowed to evoke html file, hence I can't use javascript attached.
The attached works just need to translate it to .net as I can't use html on our server
Javascripts below works just fine
<html>
<head>
</head>
<body>
<h1>NPrinting API task starter</h1>
<script src="http://code.jquery.com/jquery-1.10.1.min.js"></script>
<script type="text/javascript">
(function(){
console.log("started")
var taskIDs=[
"f3ebd873-b310-4a22-a269-24ce81b8ce74"
]
$.ajax({
url: 'URL:4993/api/v1/login/ntlm',
xhrFields: {
withCredentials: true
}
}).done(function(data) {
console.log(data);
for(var i=0;i<taskIDs.length;i++){
$.ajax({
type: "POST",
url: 'URL:4993/api/v1/tasks/'+taskIDs[i]+'/executions',
xhrFields: {
withCredentials: true
}
}).done(function(data) {
console.log("task "+i);
console.log(data);
if(i==taskIDs.length)
open(location, '_self').close();
});
}
});
})();
<!-- open(location, '_self').close(); -->
</script>
</body>
</html>
C# code which I can't complete all the below works but doesn't start the task.
//Create the HTTP Request (authenticate) and add required headers
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(URL:4993/api/v1/login/ntlm");
CookieContainer cookies = new CookieContainer();
request.CookieContainer = cookies;
request.Method = "GET";
request.UserAgent = "Windows";
request.Accept = "application/json";
// specify to run as the current Microsoft Windows user
request.UseDefaultCredentials = true;
try
{
// make the web request and return the content
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
StreamReader responseReader = new StreamReader(response.GetResponseStream());
string sResponseHTML = responseReader.ReadToEnd();
Console.WriteLine(sResponseHTML);
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
//Create second HTTP request (get list of apps) and add required headers
HttpWebRequest secondRequest = (HttpWebRequest)WebRequest.Create(@"URL:4993/api/v1/tasks/f3ebd873-b310-4a22-a269-24ce81b8ce74/executions");
//assign cookie to request to maintain session
secondRequest.CookieContainer = cookies;
secondRequest.Method = "POST";
secondRequest.UserAgent = "Windows";
secondRequest.Accept = "application/json";
// specify to run as the current Microsoft Windows user
secondRequest.UseDefaultCredentials = true;
Thanks
