angularJS的文件下载
一. 使用window.location.href+url的方式
这种方式可以获取到要下载的文件,但是当下载的文件不存在,或者下载过程中后台报错的话会发生跳转
二. 使用$http实现异步无刷新的下载文件(1)
$http({ method : "post", url : Constant.prefixUrl+"/customerQueryCount/exportMonthReport", timeout : Constant.timeout, responseType: "blob" //注意此参数 }).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("下载报表失败"); } }).error(function(data, status, headers, config){ commonService.goLoginPage(status); });
//-----------------------------------------
// 创建a标签模拟下载
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实现异步无刷新的下载文件(2) -----存在缺陷,如果用户禁用浏览器的window.open将不能实现文件的下载
$http({ method : "post", url : Constant.prefixUrl+"/customerQueryCount/exportMonthReport", timeout : Constant.timeout, responseType: "arraybuffer" //注意此参数 }).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); });
