I am using ng2-file-upload in angular 4. Is there any way to return custom data from server? How would we access it in ts file?
You should be using uploader onSuccessItem and onErrorItem callbacks:
import { Component } from '@angular/core';
import {FileUploader, FileItem, ParsedResponseHeaders} from "ng2-file-upload";
@Component({
selector: 'upload-file',
template: `
<input type="file" ng2FileSelect [uploader]="uploader">
`,
})
export class UploadFileComponent {
uploader:FileUploader;
ngOnInit(): void {
this.uploader = new FileUploader({
url: 'http://url.to/upload',
headers: [{name:'Accept', value:'application/json'}],
autoUpload: true,
});
this.uploader.onErrorItem = (item, response, status, headers) => this.onErrorItem(item, response, status, headers);
this.uploader.onSuccessItem = (item, response, status, headers) => this.onSuccessItem(item, response, status, headers);
}
onSuccessItem(item: FileItem, response: string, status: number, headers: ParsedResponseHeaders): any {
let data = JSON.parse(response); //success server response
}
onErrorItem(item: FileItem, response: string, status: number, headers: ParsedResponseHeaders): any {
let error = JSON.parse(response); //error server response
}
}
