This works in Angular 9 and 10 (note observe: 'events'
)
const headers = new HttpHeaders({
'Content-Type': 'application/json',
Accept: 'application/json',
Authorization: token
}))
const formData = new FormData();
formData.append('file_param_name', file, file.name);
this.httpClient.post(url, formData, {
headers,
reportProgress: true,
observe: 'events'
}).subscribe(resp => {
if (resp.type === HttpEventType.Response) {
console.log('Upload complete');
}
if (resp.type === HttpEventType.UploadProgress) {
const percentDone = Math.round(100 * resp.loaded / resp.total);
console.log('Progress ' + percentDone + '%');
}
});
