使用Java Rest API下载doc或pdf

Question

从服务器下载doc或pdf文件在IE 11和firefox中不起作用。它适用于Chrome。请帮忙。

我正在从javascript调用以下函数。

function downloadFile(urlToSend) {
                    var req = new XMLHttpRequest();

                    req.open("GET", urlToSend, true);
                    req.responseType = "blob";

                    req.onload = function (event) {
                       
                        var blob = req.response;

                        var fileName = 'sample.doc';
                       
                        var link = document.createElement('a');
                        link.href = window.URL.createObjectURL(blob);
                        link.download = fileName;
                        link.click();


                    };

                    req.send();
                }
