Chrome显示“已取消”成功下载文件（200状态） [英] Chrome showing "canceled" on successful file download (200 status)

问题描述

不知道这是否是一个实际的问题，但是我正在ASP.NET中编写一个文件，即使文件总是成功地通过，在Chrome的开发者工具网络标签中，我总是看到这行红色，标记为已取消。

Not sure if this is an actual problem or not, but I'm writing a file out in ASP.NET, and even though the file always successfully goes through, in Chrome's developer tools, network tab, I always see the line in red, marked "Canceled".

我已经尝试了很多方法，为了简单起见，我用一个简单的文本文件来尝试，但它是对于PDF和其他文件类型也是如此。

I've tried lots of ways of doing this - for simplicity, I'm trying this with a simple text file, but it's true for PDF and other file types as well.

WebForms：我已经尝试了很多以下组合：

WebForms: I've tried it with lots of combinations of the following:

Response.Clear();
// and/or/neither
Response.ClearHeaders();

// with and without this
Response.Buffer = true;

Response.Charset = "";
// or/neither
Response.Charset = "utf-8";

// application/pdf for PDF, also tried application/octet-stream
Response.ContentType = "text/plain";

// with and without this
Response.AddHeader("Content-Length", bytes.Length.ToString());

Response.AddHeader("Content-Disposition", "attachment; filename=1.txt");

// bytes is the UTF8 bytes for a string or the PDF contents
new MemoryStream(bytes).WriteTo(Response.OutputStream);
// or
Response.Write("12345");

// any combination of the following 3, or none at all
Response.Flush();
Response.Close();
Response.End();

MVC（2和3，尚未尝试4）：

MVC (2 and 3, haven't tried 4):

byte[] fileContents = Encoding.UTF8.GetBytes("12345");
return File(fileContents, "text/plain", "1.txt");
// or
return File(@"C:\temp\1.txt", "text/plain", "1.txt");

它始终是一样的 - 文件通过只是罚款，但开发工具显示我：

It's always the same - the file goes through just fine, but dev tools shows me this:

我是认为只是忽略它，继续生活，但红色只是打扰了我。任何想法如何处理？

I'm thinking of just ignoring it and moving on with life, but the red just bothers me. Any idea how I can deal with that?

推荐答案

这只是意味着chrome没有离开页面。行为是设计的。不要担心。

This just means that chrome didn't navigate away from the page. The behavior is by design. Don't worry about it.
