ASP. NET MVC 5 turns off XSS filtering

Add [ValidateInput (false)] to the head of the Controller method

Submitting content with HTML tags to the MVC server results in a checksum failure exception, so that the desired result is not obtained, and the method of closing is to add the [ValidateInput (false)] property to the header of the corresponding method.

Such as:

[ValidateInput (false)]         PublicActionResult SendMail (stringTitlestring[] Shoujian,stringcontent, httppostedfilebase file) {            stringSessionId = request.cookies["sessionId"]?. Value??""; if(string. IsNullOrEmpty (sessionId)) {returnRedirect ("/login/index"); } savemail (Title,shoujian,content,file,false, sessionId); returnContent ("OK"); }
