I'm attempting to fetch a logo image (such as jpeg, png, gif) from an API. While I can see the image in the Network tab, the console is throwing an error, which is displayed in the attached image. Any ideas on how to resolve this? I am using htppclient.get and .toPromise() in the latest version of Angular.
edit: I have also set this header:
const headers = new HttpHeaders().set('Content-Type', 'application/json');
return this.getHeaders().append('responseType', 'text');
If your request is returning data of type 'blob', you may need to adjust your headers accordingly. Consider changing the accept-type from JSON to image format. Take a look at the code snippet below to see how this can be achieved:
getImage() {
let httpHeaders = new HttpHeaders()
.set('Accept', "image/webp,*/*");
return this.http.get<Blob>(url, { headers: httpHeaders, responseType: 'blob' as 'json' });
}
Once you've made these changes, you should be able to create an image from the retrieved data.
To effectively handle image files, it is recommended to return the HTTP code in the following manner using Blobs.
fetchImage(imageUrl: string): Observable<Blob> {
return this.httpClient.get(imageUrl, { responseType: 'blob' });
}
For further information, please refer to this informative blog post.
While both responses provided below were helpful, my specific situation involved not creating an image initially. Upon performing a GET request and subsequently creating the image, I was able to successfully resolve the issue.
