如何使用JavaScript（React）下载pdf文件以实现Content Type application / pdf的c＃API响应

Question

我有服务器端pdf生成，为此，我正在使用c＃读取数据并使用iTectSharp生成pdf。生成pdf后，我将响应返回到UI，并且在UI上，JavaScript应下载pdf文件。但是Java脚本代码无法下载pdf。

API请求响应标头如下

Cache-Control: no-cache
Content-Disposition: attachment; filename=ReportSummary.pdf
Content-Length: 84595
Content-Type: application/pdf
Date: Wed, 13 Feb 2019 05:11:03 GMT
Expires: -1
Pragma: no-cache
Server: Microsoft-IIS/10.0
X-Powered-By: ASP.NET

在服务器上获取API的代码

using (var workStream = new MemoryStream())
            {
                using (var pdfWriter = new PdfWriter(workStream))
                {
                    ConverterProperties props = new ConverterProperties();
                    HtmlConverter.ConvertToPdf(contents, pdfWriter,props);
                    byte[] byteInfo = workStream.ToArray();

                    var res = new HttpResponseMessage(HttpStatusCode.OK);
                    res.Content = new ByteArrayContent(byteInfo);
                    res.Content.Headers.ContentType = new MediaTypeHeaderValue("application/pdf");
                    res.Content.Headers.ContentDisposition = new ContentDispositionHeaderValue("attachment")
                    {
                        FileName = "BenchmarkSummary.pdf"
                    };

                    return res;
                }
            }

前端API的代码

Service.getReport(values).then(response => {            
    var blob=new Blob([response.data]);
    const link = this.linkRef.current;
    link.href= window.URL.createObjectURL(blob);
    link.download="Report.pdf";
    link.click();
})
