使用FileSaver.js,从这里获取它
saveAs将为您下载一个pdf文件。首先,您的请求-响应类型必须是
arraybuffer
function openFile(response,fileName,saveFile){
var fileURL;
var contentType = response.headers('Content-Type');
var blob = new $window.Blob([response.data], { type: contentType });
if(saveFile){
saveAs(blob, fileName);
}else{
if($window.navigator.msSaveOrOpenBlob){
$window.navigator.msSaveOrOpenBlob(blob , fileName);
}else{
fileURL = URL.createObjectURL(blob);
$window.open(fileURL, '_blank');
}
}
}
$window
是一个AngularJS服务-对browerswindow
对象的引用
$window.navigator.msSaveOrOpenBlob
-这是一种特定于IE浏览器的方法,支持创建和下载文件,而不是IE不支持的Blob URL
saveAs
-此参考资料将帮助您:
function openFile(response,fileName,saveFile){
var fileURL;
var contentType = response.headers('Content-Type');
var blob = new $window.Blob([response.data], { type: contentType });
if(saveFile){
saveAs(blob, fileName);
}else{
if($window.navigator.msSaveOrOpenBlob){
$window.navigator.msSaveOrOpenBlob(blob , fileName);
}else{
fileURL = URL.createObjectURL(blob);
$window.open(fileURL, '_blank');
}
}
