javascript - 从 safari ASP.NET 下载时出现无法加载资源错误

Question

我使用的是 ASP.NET MVC 5，从 Safari 下载文件时遇到错误，它在 FireFox/Chrome 上正常工作。

在我的网站中，我尝试下载 xls 文件，该文件显示错误(来自 Safari)

[Error] Failed to load resource: Frame load interrupted

这是我的代码片段

var memStream = new  MemoryStream(encoding.GetBytes(model.ExportGenericHtml(true)));
           HttpResponseMessage fullResponse = >Request.CreateResponse(HttpStatusCode.OK);
           fullResponse.Content = new StreamContent(memStream);
           fullResponse.Content.Headers.ContentType = _XlmediaType;
        // Response.AddHeader("Content-Length", data.Length.ToString());
           fullResponse.Content.Headers.Add("Content-Length",  memStream.Length.ToString());
           string fileName = "transactions.xls";
           fullResponse.Content.Headers.ContentDisposition = new ContentDispositionHeaderValue("fileName") { FileName = fileName };
           fullResponse.Content.Headers.Add("x-filename", fileName);
           return fullResponse;

有什么办法可以解决这个错误吗？

Answer 1

检查这些参数:

来自Failed to load resource: Frame load interrupted - Agian

header("Pragma: public"); // required
header("Expires: 0"); 
header("Cache-Control: must-revalidate, post-check=0, pre-check=0"); 
header("Cache-Control: private",false); // required for certain browsers 
header("Content-type: application/x-unknown"); // I always use this
header("Content-Disposition: attachment; filename='theFilename.ext'");
header("Content-Transfer-Encoding: binary");
header("Content-Length: 177998"); // you might want to set this

显然上面答案中的内容类型不符合您的需求，但其他参数应该验证。
