一. 使用window.location.href+url的方式
這種方式可以獲取到要下載的文件,但是當下載的文件不存在,或者下載過程中后台報錯的話會發生跳轉
二. 使用$http實現異步無刷新的下載文件(1)
$http({ method : "post", url : Constant.prefixUrl+"/customerQueryCount/exportMonthReport", timeout : Constant.timeout, responseType: "blob" //注意此參數 }).success(function(data, status, headers, config){ var blob = new Blob([data], {type: "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"}); if(blob.size()>0){ var fileName = $rootScope.currentAdminUserId +""+ (new Date()).getTime(); var a = document.createElement("a"); document.body.appendChild(a); a.download = fileName; a.href = URL.createObjectURL(blob); a.click(); }else{ deferred.resolve("下載報表失敗"); } }).error(function(data, status, headers, config){ commonService.goLoginPage(status); });
//-----------------------------------------
// 創建a標簽模擬下載
function exportExcel(params, filename) {
return $http({
url: '/api/exportExcel',
method: "POST",
headers: {
'Content-type': 'application/json'
},
params: params,
responseType: 'arraybuffer'
}).success(function (data) {
var blob = new Blob([data], {type: "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"});
var objectUrl = URL.createObjectURL(blob);
var a = document.createElement('a');
document.body.appendChild(a);
a.setAttribute('style', 'display:none');
a.setAttribute('href', objectUrl);
a.setAttribute('download', filename);
a.click();
URL.revokeObjectURL(objectUrl);
});
}
三. 使用$http實現異步無刷新的下載文件(2) -----存在缺陷,如果用戶禁用瀏覽器的window.open將不能實現文件的下載
$http({ method : "post", url : Constant.prefixUrl+"/customerQueryCount/exportMonthReport", timeout : Constant.timeout, responseType: "arraybuffer" //注意此參數 }).success(function(data, status, headers, config){ var blob = new Blob([data], {type: "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"}); var objectUrl = URL.createObjectURL(blob); window.open(objectUrl); }).error(function(data, status, headers, config){ commonService.goLoginPage(status); });
