资源解释为Document但使用MIME类型application / zip传输:

我无法使用Web API get调用从服务器成功下载文件。下载似乎已开始,但随后Chrome抛出:

“资源被解释为文档但使用MIME类型application / zip传输”

Firefox没有说明,但下载仍然失败。

在以下设置中我做错了什么?:

    [HttpGet, Route("api/extractor/downloadresults")]
    public HttpResponseMessage DownloadResultFiles()
    {
        int contentLength = 0;
        this.ResultFiles.ForEach(f => contentLength = contentLength + f.FileSize);

        var streamContent = new PushStreamContent((outputStream, httpContext, transportContent) =>
        {
           ...zip files...
        });

        streamContent.Headers.ContentType = new MediaTypeHeaderValue("application/zip");
        streamContent.Headers.ContentLength = contentLength;
        streamContent.Headers.ContentDisposition = new ContentDispositionHeaderValue("attachment")
        {
            FileName = "result.zip"
        };

        var response = Request.CreateResponse();

        response.StatusCode = HttpStatusCode.OK;
        response.Content = streamContent;
    }

我通过以下方式触发下载:

  window.location.href = "api/extractor/downloadresults";

使用生成的标题:
