java下載文件解決net::ERR_RESPONSE_HEADERS_MULTIPLE_CONTENT_DISPOSITION及下載文件亂碼

1、java下載文件亂碼：

 String userAgent = request.getHeader("User-Agent");  
 String formFileName = file.getFileName();  
    // 針對IE或者以IE爲內核的瀏覽器：  
    if (userAgent.contains("MSIE") || userAgent.contains("Trident")) {  
        formFileName = java.net.URLEncoder.encode(formFileName, "UTF-8");  
    } else {  
        // 非IE瀏覽器的處理：  
        formFileName = new String(formFileName.getBytes("UTF-8"), "ISO-8859-1");  
    }  
    response.setHeader("Content-disposition",String.format("attachment; filename=\"%s\"", formFileName));  
    response.setContentType("multipart/form-data");   
    response.setCharacterEncoding("UTF-8");

2、解決Chrome 下載帶半角分號出現net::ERR_RESPONSE_HEADERS_MULTIPLE_CONTENT_DISPOSITION的問題：

方式一：添加雙引號
Response.AddHeader("content-disposition", "attachment; filename=\"" + FileName + "\"")

方式二：替換掉文件的半角分號

var FileName = "www.kzwr.com,酷站網軟".Replace(",", "")
Response.ContentType = "application/pdf"
Response.AddHeader("content-disposition", "attachment; filename=" & FileName)    
Response.BinaryWrite(myPDF)
