AngularJS向Web服务发送下载文件的请求

Question

我需要使用AngularJS中的HTTP POST方法将JSON发送到Web服务以下载文件。

AngularJS： -

$http
                .post(
                    'url',
                    'My Json data ')
                .success(function(response) {
                    console.log('file downloading');
                })
                .error(
                    function(response) {
                        console
                            .log('Error while downloading file');
                    });

Spring Controller： -

@RequestMapping(value = "/url", method = RequestMethod.POST)
    @ResponseBody
    public void getfile(@RequestBody List<ABC> abc, HttpServletResponse response)
            throws JRException, IOException, SQLException {
//My code here 
        response.reset();
        response.setContentType("application/x-pdf");
        response.setHeader("Content-disposition", "attachment; filename=ABC.pdf");
        final OutputStream outStream = response.getOutputStream();  
        JasperExportManager.exportReportToPdfStream(jasperPrint,outStream);
        outStream.flush();
        outStream.close();

我必须使用POST请求从angular调用它。怎么实现呢？

修改 我能够通过引用this线程来满足要求。
