Chrome的表现＆QUOT;取消＆QUOT;成功的文件下载（200状态） [英] Chrome showing "canceled" on successful file download (200 status)

问题描述

不知道这是一个实际的问题或没有，但我正在写一个文件出来在ASP.NET中，即使该文件总能成功经历，在Chrome的开发者工具，网络选项卡上，我总是看行红色，标注取消。

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".

我试过很多这样的方式 - 为简单起见，我用一个简单的文本文件尝试此，但它是PDF等多种文件类型，以及真

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的：我有很多下面的组合试了一下：

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，还没有尝试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");

它总是一样的 - 文件经过就好了，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:

我想只是忽略它，并与生活在继续，但红只是困扰我。任何想法，我该怎么处理呢？

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

这仅仅意味着Chrome未导航离开该页面。该行为是由设计。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.
