问题描述
我是angular的新手,目前我正在一个需要csv导出的项目中工作.在这里,我将Angular 6用作前端,将laravel用作后端
I'm new to angular, currently i'm working in a project which needs an csv export. Here i'm using Angular 6 as frontend and laravel as backend
这就是我使用mattwebsite/excel编写laravel函数的方式
This is how i wrote laravel function using mattwebsite/excel
// Lead export to csv
public function downloadExcel(Request $request)
{
$credentials = $request->only('token');
$token = $credentials['token'];
$userid = $this->getUseridFromToken($token);
$type = "xls";
$data = DB::table('user_mailbox AS A')
->select('A.id', 'A.name', 'A.email', 'A.phone', DB::raw('DATE_FORMAT(A.send_on, "%d / %b / %Y") as send_on'), 'B.listing_heading','B.listing_id','B.listing_heading', 'C.name')
->leftjoin('broker_listing AS B', 'B.listing_id', '=', 'A.listing_id')
->leftjoin('users AS C', 'C.id', '=', 'A.sent_by')
->where('A.sent_to', $userid)
->where('A.user_type', '1')
->orderBy('A.id', 'desc')->get()->toArray();
Excel::create('Lead_Export', function($excel) use ($data) {
$excel->sheet('Lead_Export', function($sheet) use ($data)
{
$sheet->fromArray($data);
});
})->download($type);
}
这就是我在角度分量中编写函数的方式
This is how i wrote function in angular component
// Download leads as excel
download_excel(){
const fd = new FormData();
fd.append('token',this.token);
this.brokerleads.downloadLeads(fd).subscribe(
data => this.handleResponsedwnload(data),
error => this.handleErrordwnload(error)
);
}
handleResponsedwnload(data){ console.log('test');
const blob = new Blob([data], { type: 'text/xls' });
const url= window.URL.createObjectURL(blob);
window.open(url);
}
handleErrordwnload(data){
}
服务就是这样
// Download as excel
downloadLeads(data):Observable<any>{
return this.http.post(`${this.baseUrl}downloadExcel`, data);
}
查看
<a class="export-leads" href="javascript:void(0);" (click)="download_excel()" >EXPORT LEADS</a>
在执行此操作时,我得到了这样的响应,但文件未下载
while doing this i'm getting response like this but file is not downloading
推荐答案
这也可以使用文件保护程序:
import * as FileSaver from 'file-saver';
this.http.post(`${this.baseUrl}downloadExcel`, data, { responseType: 'blob' })
.subscribe((resp: any) => {
saveAs(resp, `filename.csv`)
});
