MVC FilePathResult行動導致在Chrome

Question

重複請求我有一個MVC的行動，被稱爲如下：

http://localhost/Report/PrintContainerMasterTrayList?containerMasterId=x&type=downloadview

行動具有以下簽名

public ActionResult PrintContainerInstanceTrayList(int containerInstanceId, string type) 

這如下返回FilePathResult ：

return File(filename, "application/pdf"); 

這是除了Chrome中的請求觸發兩次外，沒有任何問題。該請求僅在Firefox和IE11中進行一次。

原始請求

GET http://localhost/DEV-SAF/Report/PrintContainerMasterTrayList?containerMasterId=x&type=downloadview HTTP/1.1 Host: localhost Connection: keep-alive Cache-Control: max-age=0 Upgrade-Insecure-Requests: 1 User-Agent: Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/52.0.2743.82 Safari/537.36 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8 Accept-Encoding: gzip, deflate, sdch Accept-Language: en-GB,en;q=0.8 Cookie: .ASPXANONYMOUS=-

的第二請求

GET http://localhost/DEV-SAF/Report/PrintContainerMasterTrayList?containerMasterId=x&type=downloadview HTTP/1.1 Host: localhost Connection: keep-alive User-Agent: Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/52.0.2743.82 Safari/537.36 Accept: */* Referer: http://localhost/DEV-SAF/Report/PrintContainerMasterTrayList?containerMasterId=x&type=downloadview Accept-Encoding: gzip, deflate, sdch Accept-Language: en-GB,en;q=0.8

從兩個請求的響應是相同的（在這種情況下達到一個4Mb的文件，該文件正在使用過多的帶寬）。

是什麼導致了這種行爲？

Answer 1

嘗試內容處置頭添加到響應你的行動與以下內容爲「附件;文件名= test.pdf」或者簡稱「附件」

Response.AppendHeader("Content-Disposition", "attachment");
