HTTP Question
how to return the data after getting response in http api call in angular 4?
This is my function which i define in my service and i am calling this
service method in my component but it return before the response has
come from http api call, so i get undefined return data.
home(){
this._http
.post("http://localhost:3000/home", {
email: JSON.parse(this.cookieService.get("token")).email
})
.subscribe(data => {
this.result = JSON.parse(data["_body"]);
console.log(this.result);
send=>{return this.result}
})
}

Return the observable from your service like the following,
home() : Observable<any> {
return this._http
.post("http://localhost:3000/home", {
email: JSON.parse(this.cookieService.get("token")).email
})
.map(data => {
let result = JSON.parse(data["_body"]);
return result;
});
}
And subscribe on the returned Observable from you component code like this,
this.chatService.home().subscribe((result) => { this.result = result; });
