api - C# POST request to webapi using a console program -


i have web api can access through browser :-

https://127.0.0.1:8443/ncrapi

i trying create simple console program in c# using vs2015 send data , receive response using http post.

here have far:-

using system; using system.net.http; using system.net.http.headers; using system.threading.tasks;  namespace websample {      class apisenddata     {         public string apifunction { get; set; }         public string dppname { get; set; }         public string cleardata { get; set; }         public string dppversion { get; set; }     }        class program     {         static void main(string[] args)         {             // main function calls async method named runasync              // , blocks until runasyncc completes.             runasync().wait();         }          static async task runasync()         {             using (var client = new httpclient())             {                 // code sets base uri http requests,                  // , sets accept header "application/json",                  // tells server send data in json format.                 client.baseaddress = new uri("https://localhost:8443/ncrapi");                 client.defaultrequestheaders.accept.clear();                 client.defaultrequestheaders.accept.add(new mediatypewithqualityheadervalue("application/json"));                   // http post                 var datatobesent = new apisenddata()                                     {                                         apifunction ="ncrsecuredata",                                         dppname ="csamplecustomer",                                         dppversion ="latest",                                         cleardata ="1234567890"                                     };                  httpresponsemessage response = await client.postasjsonasync("ncrapi", datatobesent);                  if (response.issuccessstatuscode)                 {                     // uri of created resource.                     uri ncrurl = response.headers.location;                      // whatever need here returned data //                   }             }         }     } }

however getting error on httpresonsemessage response statement....{"an error occurred while sending request."} {"the request aborted: not create ssl/tls secure channel."}

i suspect because not correctly understanding the client.baseaddress , httpresponsemessage response statements.

here have been following:- http://www.asp.net/web-api/overview/advanced/calling-a-web-api-from-a-net-client

you getting error because final address baseaddress + post address, is: http://localhost:8443/nrcapi/nrcapi , doesn't exist

try changing client.baseaddress to:

client.baseaddress = new uri("https://localhost:8443/");

for ssl connection errors, try generating trusted certificate: make https call using httpclient
