从REST通过AngularJS

Question

尝试使用OutputStream获取带有数据的excel表，但是在尝试使用angularjs FileSaver时无法获取数据并且只获取字节。

         var blob = new Blob([result.data],  {type : 'application/vnd.ms-excel'});
         FileSaver.saveAs(blob, "Report.xls");

路线呼叫

 var promise = $http.get(urlLink + '/downloadxls', {
            params: {
                search_param: searchParam
            }
        },{cache: true,responseType: 'arraybuffer',headers: {
   'Content-Type': 'application/octet-stream; charset=x-user-defined'
}});

响应标题

Access-Control-Allow-Headers:x-requested-with, content-type
Access-Control-Allow-Methods:GET OPTIONS
Access-Control-Allow-Origin:*
Access-Control-Max-Age:3600
Content-Type:application/vnd.ms-excel;charset=UTF-8
Date:Mon, 26 Sep 2016 06:02:33 GMT
Server:Apache-Coyote/1.1
Transfer-Encoding:chunked
X-Application-Context:application:8080

请求标题

Provisional headers are shown
Accept:application/json, text/plain, */*
Origin:http://localhost:9000
Referer:http://localhost:9000/

在Spring REST服务中，

response.setHeader("Content-Disposition",
            "attachment; filename=MyExcel.xls");
response.setContentType("application/vnd.ms-excel");

在Excel表格中获取字节不是正确对齐的数据，而是在后端可以正确保存数据，
