I have an Angular application 5 that makes a request to the backend made in Lumen 5.6, in this backend, I have a function that creates an excel file, with the Maatwebsite \ Excel library, for download. However I am not able to download the file through the API, if I create a route that is accessible without credentials, through the browser I can download, but the API returns me some weird characters.
What brings me back this time:
MyAPIrequest(Angula5):
Anglefunction
download(e){e.preventDefault();this.httpService.builder('/registrations/download').download().then((res)=>{letblob=newBlob([res],{type:'text/csv'});leturl=window.URL.createObjectURL(blob);window.open(url);});}Angularservice:
download(){letheader:Headers;lettoken=this.getCookie('token');this.header=newHeaders({'Authorization':'Bearer'+token,'Accept':'application/csv','responseType':'blob'});letobservable=this.watch(this.http.get(this.url,{headers:this.header}));returnthis.toPromise(observable);}Lumen5.6
publicfunctiondownloadExcel(){$data=$this->model->all();$headers=['Access-Control-Allow-Origin'=>'*','Accept'=>'application/csv','responseType'=>'blob'];$teste=Excel::create('LaravelExcel',function($excel)use($data){$excel->sheet('Excelsheet',function($sheet)use($data){$header=array('ID','FirstName','LastName',);$sheet->fromArray(array($header),null,'A1',false,false);foreach($dataas$row){$row=$row->toArray();$sheet->fromArray(array($row),null,'A1',false,false);}});})->download('xls',$headers);returnresponse()->download($teste,'myfile.csv',['Content-Type'=>'text/csv','Content-Disposition'=>"attachment; filename='myfile.csv'",
]);
}
