I use the below code but it does not work.
When I entered to homepage the log is not display as I want (In console
log, it show : *first* then *last*, and the last is *second*) so It always
return token invalid because it does not run in order. I dont know where I
wrong.
Please help me. Thank you all !
logIn(identifi : string, password : string ) {
let headers = new Headers();
headers.append('Access-Control-Allow-Origin', '*');
headers.append('Access-Control-Allow-Methods', '*');
headers.append('Access-Control-Allow-Headers', 'Content-Type,
Access-Control-Allow-Headers, Authorization, X-Requested-With');
let body = {
"user_id" : identifi,
"password" : password
};
let options = new RequestOptions({ headers: headers });
return this.http.post(api.logIn, body, options).map((res:Response) =>
res.json());
}
checkToken() {
this.storage.get('user').then((user) => {
if(user) {
this.token = user.token;
this.token_date = user.token_date - 100;
this.currentDate = new Date();
this.expDate = new Date(this.token_date * 1000);
if (this.expDate === this.currentDate) {
// token expired, login again
console.log('first');
this.logIn(user.user_id, user.password).subscribe(
data => {
this.storage.set("user", userInfo);
console.log('second');
return userInfo.token;
},
err => {
console.log(err);
});
}
}
})
}
getDataHomepage(retailerId: number,pageIndex: number) {
this.checkToken();
console.log('last');
let headers = new Headers();
headers.append('Authorization', 'Bearer ' + this.token);
let options = new RequestOptions({ headers: headers });
return this.http.get(api.promotion + '?retailer_id=' + retailerId +
'&page=' + pageIndex, options).map((res:Response) => res.json());
}
