我们刚刚开始在Chrome v.29浏览器上遇到文件下载问题。系统不会提示用户下载文件。
请参阅以下代码:
context.Response.Clear();
context.Response.ClearHeaders();
context.Response.ClearContent();
context.Response.AddHeader("Content-Disposition", "attachment; filename=Test.txt");
context.Response.CacheControl = "private";
context.Response.ContentType = "text/plain";
byte[] data = new byte[Encoding.UTF8.GetByteCount("Test")];
data = Encoding.UTF8.GetBytes("Test");
context.Response.AppendHeader("Content-Length", data.Length.ToString());
context.Response.ContentEncoding = Encoding.UTF8;
context.Response.BinaryWrite(data);
context.Response.Flush();
context.Response.End();
http header / body:
HTTP/1.1 200 OK
Date: Thu, 29 Aug 2013 21:47:44 GMT
Server: Microsoft-IIS/6.0
X-Powered-By: ASP.NET
Content-Disposition: attachment; filename=Test.txt
Content-Length: 4
Cache-Control: private
Content-Type: text/plain
Test
相同的代码适用于除chrome之外的所有浏览器!它曾经在chrome上工作,直到推出版本29 !!!
答案 0 :(得分:2)
我总是使用以下内容而没有任何问题:
context.Response.ContentType = "application/octet-stream";
或
context.Response.ContentType = "application/download";
如果您仍遇到问题,请查看chrome extensions。
使用Chrome v.29下载示例(包含Content-Type:“application / octet-stream”)
和chrome版本29.0.1547.62
