c# - Angular 2 HTTP post Web API 2 always receive null -

user.service.ts

import { injectable } '@angular/core'; import { http, response, headers } '@angular/http'; import 'rxjs/rx'; import { observable } 'rxjs/observable';  import * myglobal '../global';  @injectable() export class userservice {  constructor(private http: http) {}  postuser(user:any[]) {   let headers = new headers({ 'content-type': 'application/x-www-form-   urlencoded; charset=utf-8', 'accept' : 'application/json' });   return this.http.post(myglobal.myurl + 'user/insert', json.stringify(user)   , {headers: headers});   } } 

user.component.ts

submitform(data: any):void{   console.log(data);   this._service.postuser(data)   .subscribe(   (response) => console.log(response),   (error) => console.log(error)   ); } 

web api

[httppost] [route("api/user/insert")] public httpresponsemessage insertvehiclesdevice(modeluser data) {   //stuff   return new httpresponsemessage { statuscode = httpstatuscode.ok }; } 

when invoke method insert, data arrive in null or zero, had change { 'accept' : 'application/json' } line { 'content-type': 'application/x-www-form-urlencoded; charset=utf-8', 'accept' : 'application/json' } because gave me 405 error

thanks in advance everyone

problem here:

return this.http.post(myglobal.myurl + 'user/insert'       , json.stringify(user)      , {headers: headers}); 

change to:

return this.http.post(myglobal.myurl + 'user/insert'       , json.stringify(user)      , {headers: headers})    .map(    (response: response) =>response.json())    .catch(this._errorhandler); 

error handler:

_errorhandler(error:response){   console.log(error);   return observable.throw(error || "internal server error"); } 

you need import:

  import { http, response } '@angular/http';   import { observable } 'rxjs/observable';   import 'rxjs/add/operator/map';   import 'rxjs/add/operator/catch';   import 'rxjs/add/observable/throw';
