I've come across several examples on the web that look like this:
createArticle(article: Article): Observable<Article> {
return this.http.post<Article>(this.url, article);
}
These examples all assume that the web API's response contains an Article. But how can I modify the above code so that it posts an Article to the web API and receives a response in the form of a string?
I stumbled upon a solution that worked flawlessly in resolving the issue at hand.
Simply changing the return type will not suffice; you must also include headers in your request like so:
createArticle(article: Article): Observable<any> {
var headers = new HttpHeaders().set('Content-Type', 'text/plain; charset=utf-8');
return this.http.post<any>(this._url, article, { headers, responseType: 'text' as 'json' })
.pipe(catchError(err => {
console.log(err);
return Observable.throw(err);
}));
}
