I'm using the same code to get/post to my API as I did with my previous applications, but now it doesn't work:
let options_ = {
method: "get",
headers: new Headers({
"Content-Type": "application/json",
"Accept": "application/json"
})
};
return this.http.get(url_, options_).flatMap((response_) => {
return this.processResponse(response_);
})
this code works for me in other applications but in this one doesn't. It doesn't reach the server and in the traffic tab I see no request. I've enabled cors on the server. How do I fix this issue?
A request isn't executed unless you subscribe
to the Observable
returned by the get
function, as shown in the example below:
doGet() {
return this.http.get(url_, options_).flatMap((response_) => {
return this.processResponse(response_);
});
}
yourOtherFunction() {
doGet().subscribe(result => {
// your code
});
}
Try by using observables fucntions
Get Method
getFuntion(): Observable<any[]> {
return this._http.get(this._baseUrl+'/controller/api')
.map(res => {
return res.json().map(item => {
return item;
});
});
}
Post Method
postFunction(id, action) {
let data = {
id: id,
action: action
};
let body = JSON.stringify(data)
let head = new Headers({
'Content-Type': 'application/json'
});
return new Observable(observer => {
this._http.post(this._baseUrl+'/controller/api/',
body , {headers : head})
.map((res: Response) => res.json())
.subscribe(res => {
observer.next(res);
observer.complete();
});
});
}
