使用AngularJS的头文件中的“内容-处置”和文件名

Question

我使用angularjs 1.3.14

我有一个java REST服务生成一个xml文件，它的头是：“Content-Disposition”，“attachment；filename=yourfilename”；

$http.get('/someUrl').success(function(data, status, headers){
var myHeaders = headers();
...
});

Java服务：

@GET
@Path(EXPORT_URL)
@Produces(MediaType.APPLICATION_XML)
public Response export(@Context HttpServletRequest request) {
    String userName = request.getRemoteUser();
    if (userName != null) {
        ...
        ResponseBuilder response = Response.ok(myObject);
        response.header("Content-Disposition", "attachment; filename=myFile.xml");
        return response.build();
    } else {
        return Response.status(Status.FORBIDDEN).build();
    }
}

两年后，我找到了一个解决办法：

@RequestMapping(value = "/export", method = RequestMethod.GET, produces = MediaType.APPLICATION_XML)
public ResponseEntity<String> export(...

HttpHeaders headers = new HttpHeaders();
headers.setAccessControlExposeHeaders(Collections.singletonList("Content-Disposition"));
headers.set("Content-Disposition", "attachment; filename=" + filename);
return new ResponseEntity<>(exportedContent, headers, HttpStatus.OK);
