I'm encountering a really strange problem with my Angular 2 application. I actually want to make a POST call containing a JSON to my Play Scala API, but it keeps want to try to make an OPTIONS call.
Here is my code :
LoginService
constructor (private _apiEndpoint: ApiEndpoint) {}
postLogin(login: string, credential: string): Observable<AuthToken> {
let headers = new Headers({ "Content-Type": "application/json" })
let jsonLogin = {"login": login, "password": credential}
return this._apiEndpoint.postLogin(JSON.stringify(jsonLogin), headers)
.map(this._apiEndpoint.extractData)
}
ApiEndpoint
constructor (private _http: Http) {}
postLogin(body: string, options: any) {
return this._http.post("http://localhost:9000/login", body, {
headers: options
})
}
And then when I try to make the call (I've tried to console.log to check the JSON and it's correct), and the call tries to make an OPTIONS call for whatever reason :
Has anyone an idea ? Thanks !
You are making a cross domain request.
The request is to localhost:9000
and is made from localhost:9002
.
The browser creates a pre-flight request with the OPTIONS verb in order to know if he can continue and make the "real" request.
