I have to submit a form along with image. i have tried this code (with multiple ways) but did't work for me. is there anyone having working demo of file uploading using angular2 please help me out.
component.html
<form class="form-horizontal" role="form" >
<div class="form-group">
<label class="control-label col-sm-4" for="myname" style="">Name<span class="asterisk">*</span></label>
<div class="col-sm-7">
<div>
<input type="text" class="form-control" id="myname"
[(ngModel)]="myfile.name">
</div>
</div>
</div>
<div class="form-group">
<label class="control-label col-sm-4" for="myimage">Image</label>
<div class="col-sm-7">
<div>
<input type="file" (change)="fileChangeEvent($event)" placeholder="Upload file..." />
</div>
</div>
</div>
<div class="form-group">
<div class="text-center">
<button type="button" (click)="upload()">Upload</button>
</div>
</div>
</form>
component.ts
myfile={
"name":"Mubashshir",
"image":''
}
fileChangeEvent(fileInput: any){
this.myfile.image = fileInput.target.files;
}
upload(){
this.base_path_service.PostRequest('http://128.199.190.109/api/school/schoolDetail/',this.myfile)
.subscribe(
data => {
console.log("data submitted");
},
err => console.log(err),
() =>{
console.log('Authentication Complete');
}
);
}
In fact, the Http
class doesn't support that at the moment.
You need to leverage the underlying XHR object to do that:
import {Injectable} from 'angular2/core';
import {Observable} from 'rxjs/Rx';
@Injectable()
export class UploadService {
constructor () {
this.progress$ = Observable.create(observer => {
this.progressObserver = observer
}).share();
}
private makeFileRequest (url: string, params: string[], files: File[]): Observable {
return Observable.create(observer => {
let formData: FormData = new FormData(),
xhr: XMLHttpRequest = new XMLHttpRequest();
for (let i = 0; i < files.length; i++) {
formData.append("uploads[]", files[i], files[i].name);
}
xhr.onreadystatechange = () => {
if (xhr.readyState === 4) {
if (xhr.status === 200) {
observer.next(JSON.parse(xhr.response));
observer.complete();
} else {
observer.error(xhr.response);
}
}
};
xhr.upload.onprogress = (event) => {
this.progress = Math.round(event.loaded / event.total * 100);
this.progressObserver.next(this.progress);
};
xhr.open('POST', url, true);
xhr.send(formData);
});
}
}
