I am trying to pass a JSON Object from a typescript POST call to a Web API method. Fiddler shows that the object has been converted into JSON and the Content-Type is 'application/JSON'. But at the API controller, the parameter value displays null instead of JSON.
Typescript:
createPO(product: string): Promise<string> {
var headers = new Headers();
headers.append('Content-Type', 'application/json');
let options = new RequestOptions({ headers: headers });
return this._http.post(this._creatPOUrl, JSON.stringify(product), options)
.toPromise()
.then(response => <string>response.statusText)
.catch(this.handleError);
}
Web API: [HttpPost] public async Task CreatePOInMO([FromBody] string product) { return Ok(); }
product contains null. If I pass the actual value inside product object from typescript(which is a JSON) , it works. But I cannot hard code like this.
I followed this post : Angular2 Service not passing JSON to WebAPI But it looks like I am doing whatever is mentioned here.
