Question

我使用angularjs 1.3.14

我有一个java REST服务生成一个带有这个标题的xml文件：＆＃34; Content-Disposition＆＃34;，＆＃34; attachment;文件名= yourFileName＆＃34 ;;

我需要在AngularJS上获取带有我文件名的文件。

我有这段代码：

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

但在myHeaders中只有{content-type =＆＃34; application / xml＆＃34;}。 我需要找到＆＃34; Content-Disposition＆＃34;，＆＃34;附件;文件名= yourFileName＆＃34;

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();
    }
}

Answer 1

这是服务器端CORS问题。您需要启用此功能：

"Access-Control-Expose-Headers", "Content-Disposition"

Answer 2

2年后，我找到了解决方案：

@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);

＆＃34;内容处置＆＃34; AngularJS
