[英]Symfony and PHPExcel (with React.js), not downloading
我正在使用liuggio / ExcelBundle,這是我編寫和下載xlsx的代碼:
$writer = $this->get('phpexcel')->createWriter($phpExcelObject, 'Excel2007');
$response = $this->get('phpexcel')->createStreamedResponse($writer);
$dispositionHeader = $response->headers->makeDisposition(
ResponseHeaderBag::DISPOSITION_ATTACHMENT,
'XXX_-_' . ( new \DateTime() )->format( 'Y_n_j' ) . '.xlsx'
);
$response->headers->set('Content-Type', 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet; charset=utf-8');
$response->headers->set('Cache-Control', 'maxage=1');
$response->headers->set('Content-Disposition', $dispositionHeader);
當我直接從React組件調用該方法時,它會下載確定:
e.preventDefault();
location.href = path.url_descarga_excel;
$.UIkit.init();
但是我需要傳遞一些論點。 當我嘗試使用AJAX下載時:
e.preventDefault();
var sist_electrico = {
sic: ReactDom.findDOMNode(this.refs.SIC).checked,
sing: ReactDom.findDOMNode(this.refs.SING).checked
};
var periodo = {
inicio: this.refs.fechaInicio.getValue(),
fin: this.refs.fechaFin.getValue()
};
var form = $('input[name="radio_tipoForm"]:checked').val();
$.ajax({
url:path.url_descarga_excel, async:false,
type:"post", dataType:"json", data:{form, sist_electrico, periodo},
});
它不會下載,只是在Chrome的預覽中顯示文件的字符:

我做錯了什么?
好吧,終於我做到了:
exportarExcel:function(e){
e.preventDefault();
var sist_electrico = {
sic: ReactDom.findDOMNode(this.refs.SIC).checked,
sing: ReactDom.findDOMNode(this.refs.SING).checked
};
var periodo = {
inicio: this.refs.fechaInicio.getValue(),
fin: this.refs.fechaFin.getValue()
};
var form = $('input[name="radio_tipoForm"]:checked').val();
location.href = path.url_descarga_excel + "?form=" + form + "&sist_electrico=" + sist_electrico + "&periodo=" + periodo;
$.UIkit.init();
帶參數的舊location.href。 現在,PHP正在接收參數,並且已正確下載xlsx。
