Hi,

Can someone post working code example on how to read HTTP response headers? I am having issues with this.

Thanks

The res has already the headers data. Just don’t call .map function

Hi, How are you?
Could you tell me how did you to get Set-Cookie value from the header? I am trying to get it with map, but it isn’t work, What way did you use?

My code:
this.http.post(‘http://localhost:8080/NXV/Login’, body)
.map((response: Response) => {
console.log(response);
});

Try this one
this.http.post(APIVariables.API_URL+‘user/login’,body,options)
.map(res => res.json()).subscribe(res => {
// let alert = this.alertCtrl.create({
// title: ‘Response message’,
// subTitle: res.message,
// buttons: [‘Dismiss’]
// });
// alert.present();

this.userData.login(res.data.email);
this.navCtrl.setRoot(HomePage);

}, err => {
this.spinner=false;
let alert = this.alertCtrl.create({
title: ‘Response message’,
subTitle: err,
buttons: [‘Dismiss’]
});
alert.present();
});
