如何使用AngularJS并调用MVC API下载文件？ [英] how to download file using AngularJS and calling MVC API?

问题描述

我使用AngularJS，我有一个MVC 4 API，它返回的Htt presponseMessage带有附件。

I am using AngularJS, and I have a MVC 4 API that returns a HttpResponseMessage with an attachment.

var result = new MemoryStream(pdfStream, 0, pdfStream.Length) {
     Position = 0
};
var response = new HttpResponseMessage {
     StatusCode = HttpStatusCode.OK,
     Content = new StreamContent(result)
};
response.Content.Headers.ContentDisposition = 
           new ContentDispositionHeaderValue("attachment") {
                    FileName = "MyPdf.pdf"
           };
response.Content.Headers.ContentType = new MediaTypeHeaderValue("application/octet-stream");
return response;

推荐答案

我有同样的问题。通过使用所谓的JavaScript库解决了它 FileSaver

I had the same problem. Solved it by using a javascript library called FileSaver

就叫

saveAs(file, 'filename');

展开HTTP POST请求：

$http.post('apiUrl', myObject, { responseType: 'arraybuffer' })
  .success(function(data) {
            var file = new Blob([data], { type: 'application/pdf' });
            saveAs(file, 'filename.pdf');
        });
