 /*** to distinguish between IE and other browser download file garbled problem *@paramRequest *@paramFileName *@return     */     Publicstring GetFileName (httpservletrequest req,string fileName) {string useragent= Req.getheader ("User-agent"); UserAgent= UserAgent = =NULL?"": Useragent.tolowercase (); String name=FileName; Try {
For IE or IE as the kernel browser:if(Useragent.contains ("MSIE") | | Useragent.contains ("Trident") ) {Name= Urlencoder.encode (Name, "UTF-8")); }Else{Name=NewString (Name.getbytes (), "Iso-8859-1"); }        } Catch(Exception e) {Throw Newsysexception (Errorconstants.common_system_error, E); }        returnname; }

Online Many examples are used msie and like Gecko to make a distinction, said Ie11 removed MSIE;

Personally test Google browser also with like Gecko,ie11 msie not removed, and with Trident tag

The conclusion is not to use like Gecko to make a distinction, and finally

 Public void Exportexcel (httpservletrequest req,httpservletresponse response) {        try{              Response.setcontenttype ("Application/octet-stream");               = "file name";              Response.AddHeader ("Content-disposition", "Attachment;filename=" +getfilename (req,excelname) + ". xls");              = response.getoutputstream ();              Testservice.export (out);          } Catch (Exception e) {//          }
