I want try do a Post request from my frontend (Angular 2) to my backend (Spring). But I can't.
The error:
GET http://localhost:8080/loginPost 405 ()
Failed to load http://localhost:8080/loginPost: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://192.168.0.190:4200' is therefore not allowed access. The response had HTTP status code 405.
My Angular Service:
import {Injectable} from "@angular/core"; import { Headers, Http } from '@angular/http'; import 'rxjs/add/operator/toPromise'; import { Login } from'../data-login/models/login.model'; @Injectable() export class LoginService{ private loginUrl = 'http://localhost:8080/loginPost'; // URL to web API private headers = new Headers({'Content-Type': 'application/json'}); constructor(private http: Http){} loginQuery(login: Login){ console.log(login.id); return this.http.request(this.loginUrl,JSON.stringify(login)); } } My Spring Backend Code:
import org.springframework.http.HttpStatus; import org.springframework.http.MediaType; import org.springframework.http.ResponseEntity; import org.springframework.web.bind.annotation.*; @RestController public class LoginProvider { @CrossOrigin(origins = "http://192.168.0.190:4200") @PostMapping(value="/loginPost", consumes = { MediaType.APPLICATION_JSON_UTF8_VALUE }) public ResponseEntity<?> verifyLogin(@RequestBody String maoe){ System.out.println(maoe); return new ResponseEntity<>(HttpStatus.OK); } } I need to read the Json sent by my frontend, checking and responding with OK, no problems. But I can not read Json. I'm trying to store it in the variable "maoe"
