I have written a method in my service:
getPost(nid: string): Observable<Post[]>{
let url = "http://test.co.uk/api/v1/basic/" + nid;
return this.http.get(url, {headers: this.headers}).map(res => res.json() as Post).catch(err => {
return Observable.throw(err);
});
}
Here is the structure of my component class:
export class PostDetailComponent implements OnInit {
posts: Post[] = [];
post: Post = new Post();
constructor(
private route: ActivatedRoute,
private postService: PostService
) { }
ngOnInit() {
this.route.params.switchMap((params: Params) => {
let nid = params ['nid'];
return this.postService.getPost(nid); }).subscribe(res => {
console.log(res)
this.post = res as Post;
}, err =>{
console.log(err);
});
}
}
This is the JSON feed data (containing one object in the array):
[
{
"nid":"3",
"title":"When Unity meets Vuforia",
"body":"<p>Unless you have been living under a rock in the past 7 - ...",
"uid":"admin",
"path":"\/node\/3",
"field_article_image":"http:\/\/test.co.uk\/sites\/default\/files\/when-unity-meets-vuforia_0.jpg?itok=BGYaotay"
}
]
When I try to display {{post}}, it shows as [object Object] on the screen.
Displaying {{post | json}} shows the raw JSON feed data.
However, trying to show {{post.title}} or {{post?.title}} does not display anything.
The class Post has the following structure:
export class Post{
constructor(
public nid?: string,
public title?: string,
public body?: string
public image?: string
){
}
}
Any suggestions on how to solve this issue?
