html-encode

问题 Yes, I've googled it, and surprisingly got confusing answers. One page says that < > & " are the only reserved characters in (X)HTML. No doubt, this makes sense. This page says < > & " ' are the reserved characters in (X)HTML. A little confusing, but okay, this makes sense too. And then comes this page which says < > & " © ° £ and non-breaking space ( &nbsp ) are all reserved characters in (X)HTML. This makes no sense at all, and pretty much adds to my confusion. Can someone knowledgeable,

问题 What is the easiest way to Html encode in PHP? 回答1: By encode, do you mean: Convert all applicable characters to HTML entities? htmlspecialchars or htmlentities You can also use strip_tags if you want to remove all HTML tags : strip_tags Note: this will NOT stop all XSS attacks 回答2: Encode.php <h1>Encode HTML CODE</h1> <form action='htmlencodeoutput.php' method='post'> <textarea rows='30' cols='100'name='inputval'></textarea> <input type='submit'> </form> htmlencodeoutput.php <?php $code

问题 I have a string that is HTML encoded: '''<img class="size-medium wp-image-113"\ style="margin-left: 15px;" title="su1"\ src="http://blah.org/wp-content/uploads/2008/10/su1-300x194.jpg"\ alt="" width="300" height="194" />''' I want to change that to: <img class="size-medium wp-image-113" style="margin-left: 15px;" title="su1" src="http://blah.org/wp-content/uploads/2008/10/su1-300x194.jpg" alt="" width="300" height="194" /> I want this to register as HTML so that it is rendered as an image by

问题 I am not concerned about other kinds of attacks. Just want to know whether HTML Encode can prevent all kinds of XSS attacks. Is there some way to do an XSS attack even if HTML Encode is used? 回答1: No. Putting aside the subject of allowing some tags (not really the point of the question), HtmlEncode simply does NOT cover all XSS attacks. For instance, consider server-generated client-side javascript - the server dynamically outputs htmlencoded values directly into the client-side javascript,

问题 I am developing web application on ASP.NET and I am getting textarea input from users and later display this input on website. While saving input into database I am not encoding input and directly write them into db. If input contains "enter" I don't want to lose line breaks. So I am replacing data like that: Replace("\r\n", " <br /> ") And to prevent XSS attack before displaying I am encoding data using Microsoft's AntiXSS library's Microsoft.Security.Application.Encoder.HtmlEncode function.

问题 I want to be able to pass any string to the buttons text in JQuery UI. Suppose I have this string: Ajouter L'amie a la liste "amies" The only way to actually pass this text without causing a massive JavaScript error is by HTML-encoding it. registerhtml.dialog({ modal: true, title: 'My Dialog Title', resizable: false, buttons: [ { text: 'Ajouter L'amie a la liste "amies"', click: function(){ // Do something important $(this).dialog('close'); } }, { text: 'Cancel', click: function() { $(this)

问题 I am fairly new to asp.net and come into a problem whilst using a gridview. I have added some entries that contain the "&" symbol eg "PR Murphy & Associates". I haven't done any encoding of my data prior to inserting it into the database. When the gridview is changed to edit mode my text looks like this: "PR Murphy & Associates" Is thee a ny way I can stop it from encoding the information, I mean just keep the text as "PR Murphy & Associates" when inserting and then after/during an edit.

问题 The HttpUtility class provides for both encoding and decoding. But, when I use the MS AntiXSS 3.1 Library I have a set of methods only for encoding, does this mean decoding can be avoided? For example Before applying AntiXSS: lblName.Text = "ABC" + "<script> alert('Inject'); </script"; After applying AntiXSS: lblName.Text = AntiXSS.HTMLEncode("ABC" + "<script> alert('Inject'); </script"); So, after applying the encoding, the HTML tags show up in my Label control. Is this the desired outcome?

问题 We're having conflict with coworkers on whether we should htmlencode user input and then save it to db ( vs saving it straight forward as it is) I also found various answers which says that DB should save the plain(!) input. Why ? because DB should know that the user length is 1 in < and not 4 in < The html encoding should only be made when outputting. but: Having said that , I see that Stackoverflow is not following this rule. When I save a question here at SO , which contains plain < it

问题 Here I've found a grate way to HTML encode/escape special chars. Now I wonder how to unescape HTML encoded text in C++? So codebase is: #include <algorithm> namespace xml { // Helper for null-terminated ASCII strings (no end of string iterator). template<typename InIter, typename OutIter> OutIter copy_asciiz ( InIter begin, OutIter out ) { while ( *begin != '\0' ) { *out++ = *begin++; } return (out); } // XML escaping in it's general form. Note that 'out' is expected // to an "infinite"
