I am integrating Neo4j into my angular and nodejs application. I have to access the Neo4j database using bolt url as http doesn't work in my case.
Because i am getting error in console as -
Response with status: 0 for URL: null
and
Failed to load http://localhost:11002/viewNodesStart: Response for
preflight has invalid HTTP status code 404.
Angular code -
app.component.ts
export class Neo4jPrimaryComponent implements OnInit {
constructor(private http: Http, private notify: ToasterService) {
}
ngOnInit() {
this.viewNodesStart();
}
emptyObj;
info;
// ------------------------------- Nodes Entire Data -------------
viewNodesStart() {
console.log("INSIDE viewNodesStart()")
// Nodes Value
console.log("inside Nodes Value");
var data = localStorage.getItem('token');
console.log("data is=>",data);
var url = config.url;
var port = config.port;
'Bearer ' + localStorage.getItem('token') }) }
this.http.post("http://"+url+":"+port+"/viewNodesStart",this.emptyObj,
{ headers: new Headers({ 'Authorization': 'Bearer ' +
localStorage.getItem('token') }) } )
.map(Response => Response.json())
.subscribe((res: Response) => {
console.log("XXXXXXXXXXXX", res);
this.info = res;
console.log('success', this.info.statusCode);
if (this.info.statusCode == 200) {
this.notify.Success("Data added successfully");
} else {
this.notify.Error("Data is not inserted")
}
});
}
}
