从服务器收到的重复标头 [英] Duplicate headers received from server

问题描述

从服务器收到重复的标头

Duplicate headers received from server

来自服务器的响应包含重复的标头.此问题通常是错误配置的网站或代理的结果.只有网站或代理管理员可以解决此问题.

The response from the server contained duplicate headers. This problem is generally the result of a misconfigured website or proxy. Only the website or proxy administrator can fix this issue.

错误 349 (net::ERR_RESPONSE_HEADERS_MULTIPLE_CONTENT_DISPOSITION):收到多个不同的 Content-Disposition 标头.这是不允许的，以防止 HTTP 响应拆分攻击.

Error 349 (net::ERR_RESPONSE_HEADERS_MULTIPLE_CONTENT_DISPOSITION): Multiple distinct Content-Disposition headers received. This is disallowed to protect against HTTP response splitting attacks.

我在 chrome 中导出为 pdf 时发现了这个错误.

I found this error while exporting to pdf in chrome.

Response.Buffer = false;
Response.ClearHeaders();
string ext = objProp.PACKAGEFILENAME.Substring(objProp.PACKAGEFILENAME.LastIndexOf("."));
string ext1 = ext.Substring(1);
Response.ContentType = ext1;
Response.AddHeader("Content-Disposition", "target;_blank,attachment; filename=" + objProp.PACKAGEFILENAME);
const int ChunkSize = 1024;
byte[] binary = objProp.PACKAGEDOCUMENT;
System.IO.MemoryStream ms = new System.IO.MemoryStream(binary);
int SizeToWrite = ChunkSize;

for (int i = 0; i < binary.GetUpperBound(0) - 1; i = i + ChunkSize)
{
    if (!Response.IsClientConnected) return;
    if (i + ChunkSize >= binary.Length) SizeToWrite = binary.Length - i;
    byte[] chunk = new byte[SizeToWrite];
    ms.Read(chunk, 0, SizeToWrite);
    Response.BinaryWrite(chunk);
    Response.Flush();
}
Response.Close();

如何解决这个问题?

推荐答案

这个有点旧，但在谷歌排名中很高，所以我想我会抛出我从 Chrome，pdf 显示，从服务器收到的重复标题

This ones a little old but was high in the google ranking so I thought I would throw in the answer I found from Chrome, pdf display, Duplicate headers received from the server

基本上我的问题也是文件名包含逗号.替换逗号以删除它们，您应该没问题.我制作有效文件名的功能如下.

Basically my problem also was that the filename contained commas. Do a replace on commas to remove them and you should be fine. My function to make a valid filename is below.

    public static string MakeValidFileName(string name)
    {
        string invalidChars = Regex.Escape(new string(System.IO.Path.GetInvalidFileNameChars()));
        string invalidReStr = string.Format(@"[{0}]+", invalidChars);
        string replace = Regex.Replace(name, invalidReStr, "_").Replace(";", "").Replace(",", "");
        return replace;
    }
