Angular 2 HTTP post no HTTP-resource found - asp.net

Question

I am using Angular 2 in order to send http requests to the server.
The server is running with ASP.Net.
My API:
public class LagerController : ApiController
{
public IHttpActionResult RepHistorie(string vnr, string lagerort)
{
...
}
}
So I would call the API with
http://123.456.7.89/api/lager?vnr=W17291092373&lagerort=0382691395
This works fine when using a tool called postman with wich you can test API's.
But when making a post request with Angular 2, it doesn't work.
It says that the HTTP-resource is not found.
Angular 2:
submit() {
var body = 'vnr=W17291092373&lagerort=0382741400';
var link = 'http://123.456.7.89/api/lager';
this.http.post(link, body)
.subscribe(data => {
console.log(data);
}, error => {
console.log("Oooops!");
});
}
It seems like the parameters aren't added correctly.

Answer 1

This needs clarification, since the API above seems to be a GET Request.
In case it is a POST Request , then you should use the whole URL while running the API
In case you want to submit an object , you should use [FromBody] as a parameter
Example
[HttpPost]
public IHttpActionResult( [FromBody]YourObject item ) {
}
====
Client-side
var postUrl = 'http://123.456.7.89/api/lager?vnr=W17291092373&lagerort=0382691395';
var postObject = {};
http.post(postUrl,postObject)
For GET request where you would like to use QueryString
[HttpGet]
public IHttpActionResult RepHistorie([FromQuery]string vnr,[FromQuery]string lagerort){
...
}
====
// Query string can be built using RequestOptionsArgs as well
var builtUrl = 'http://123.456.7.89/api/lager?vnr=W17291092373&lagerort=0382691395';
http.get(builtUrl)
Alternative way is to
var getUrl = 'http://webapi/api/lager';
var requestOptions = {};
http.get(getUrl,requestOptions);
Reference:
Angular HTTP: https://angular.io/api/http/Http , check get() and post() methods
RequestOptionsArgs : https://angular.io/api/http/RequestOptionsArgs
