I`m trying to access a URL with Basic Authentication.
The URL returns JSON data.
How can I add my username and password to this http request below?
private postsURL = "https://jsonExample/posts";
getPosts(): Observable<AObjects []>{
return this.http.get<AObjects[]>(this.postsURL);
}
Refer to https://angular.io/guide/http or https://v6.angular.io/guide/http#adding-headers
import { HttpHeaders } from '@angular/common/http';
const httpOptions = {
headers: new HttpHeaders({
'Content-Type': 'application/json',
'Authorization': 'Basic ' + btoa('username:password')
})
};
Then use the headers:
return this.http.get<AObjects[]>(this.postsURL, httpOptions);
http.get() ? Do you use any header that relates to a different method, like pre-flight request?i don't know what you want to do exactly after getting authorized, but to get authorized using a simple call with basic authentication you need to do like this:
let authorizationData = 'Basic ' + btoa(username + ':' + password);
const headerOptions = {
headers: new HttpHeaders({
'Content-Type': 'application/json',
'Authorization': authorizationData
})
};
this.http
.get('{{url}}', { headers: headerOptions })
.subscribe(
data => { // json data
console.log('Success: ', data);
},
error => {
console.log('Error: ', error);
});
Since btoa() ist deprecated the following might be a cleaner solution than https://stackoverflow.com/a/53613780
import { HttpHeaders } from '@angular/common/http';
const username = 'JohnDoe'
const password = 'JonhnsSecret'
const token = Buffer.from(`${username}:${password}`, 'utf8').toString('base64');
const httpOptions = {
headers: new HttpHeaders({
'Content-Type': 'application/json',
'Authorization': 'Basic ' + token)
})
};
Then use the headers:
return this.http.get<AObjects[]>(this.postsURL, httpOptions);
postmethod instead ofget? If you are usinggetthen you should append credentials to the header of a request
