post data in angular2 - json

Question

I am facing the issue of json added being added to the url after calling the service to add the data.
below is my file
first.ts
CreateNew(): void {
this.router.navigate(['/detail', 0]);
}
detail.ts
Submit() {
let templateId;
this.route.params.subscribe(
(param: any) => {
templateId = +param['templateid']; });
if (templateId === 0) {
this.jobservice.addJob(this.job).subscribe(error => this.errorMessage = <any>error);
}
this.router.navigate(['/template']);
}
service.ts
addJob(job: Job): Observable <Job> {
let headers = new Headers({ 'Content-Type': 'application/json' });
let options = new RequestOptions({ headers: headers });
console.log(job);
return this.http.post('http://sample/api/Product/AddProduct', JSON.stringify(job), options).map(this.extractData).catch(this.handleError);
}
I am not able to find the issue why it is adding the json data to the url.

When you use the RequestOption, you dont use the method post, get, put or delete. But you use "request". Here is a sample request that works:
post<RQ, RS>(url: string, request: RQ, responseType: RS, withToken: boolean): Promise<RS> {
let postReq: Request = this.createAuthorizationHeader<RQ>(url, request, RequestMethod.Post, withToken);
return this.http.request(postReq).toPromise()
.then(res => {
return this.processingData<RS>(res, responseType);
})
.catch(this.handleError);
}
Then here you add your header to the request:
/**
* This function updates the token in the header
*/
createAuthorizationHeader<RQ>(url: string, requestData: RQ, method: RequestMethod, withToken: boolean) {
let headers = new Headers();
let options = new RequestOptions({
method: method,
url: url
});
/**
* Include token when boolean is passed
*/
if (withToken) {
headers.append('token', token);
options.headers = headers;
}
/**
* create bosy for post and put
*/
if (method === RequestMethod.Post || method === RequestMethod.Put) {
// do something
}
let request = new Request(options);
return request;
}
This should work, remember to use "http.request.." when you use request options
import { Http, Request, Response, Headers, RequestMethod, RequestOptions } from '#angular/http';
...
let headers = new Headers({ 'Content-Type': 'application/json' });
let options = new RequestOptions({
method: RequestMethod.Post,
url: url,
headers = headers,
body: job
});
let request = new Request(options);
console.log(options);
return this.http.request(options).map(this.extractData).catch(this.handleError);

The issue was that while refresh of page it was showing 404 error.
In app.module.ts
Add imports: import { HashLocationStrategy, LocationStrategy } from '#angular/common';
And in NgMoudle provider, add: {provide: LocationStrategy, useClass: HashLocationStrategy}
which fixed the issue.

This should be working out fine. I have this working on my environment using angular 2.1.0.
import { Http, Request, Response, Headers, RequestMethod, RequestOptions } from '#angular/http';
...
let headers = new Headers({ 'Content-Type': 'application/json' });
let options = new RequestOptions({
method: RequestMethod.Post,
url: 'localhost:51293/template',
headers = headers,
body: job
});
let request = new Request(options);
console.log(options);
return this.http.request(options).map(this.extractData).catch(this.handleError);
