问题 Is there a similar or equivalent function in Python to the PHP function htmlspecialchars()? The closest thing I've found so far is htmlentitydefs.entitydefs(). 回答1: Closest thing I know about is cgi.escape. 回答2: from django.utils.html import escape print escape('<div class="q">Q & A</div>') 回答3: You probably want xml.sax.saxutils.escape: from xml.sax.saxutils import escape escape(unsafe, {'"':'"'}) # ENT_COMPAT escape(unsafe, {'"':'"', '\'':'''}) # ENT_QUOTES escape(unsafe) # ENT_NOQUOTES

问题 I pass my template an array of strings which I would like to convert to a jaavascript array: Controller file (php): $myVar = array('a','b','c'); Desired html: var myVar = ["a","b","c"]; I try the following code (twig): var myVar = ["{{ myVar | join('","') }}"]; But the twig generator converts the quotation marks to html entities and this is the result: var myVar = ["a","b","c"]; Some idea? 回答1: You need to apply the raw filter: var myVar = ["{{ myVar | join('","') | raw }}"]; 来源： https:/

问题 I am a little confused on this. I have been reading about htmlspecialchars() and I am planning to use this for the textareas POST to prevent XSS attack. I understand that usually htmlspecialchars() are used to generate the HTML output that is sent to the browser.

Before anyone says anything, yes, I am filtering on db input as well as using prepared statements with bindings. I am only concerned about securing the output. I am confused as to when to use ENT_COMPAT , ENT_QUOTES , ENT_NOQUOTES . I came across the following excerpt while doing my research: The second argument in the htmlspecialchars() call is ENT_COMPAT . I've used that because it's a

问题 I am trying to use the e function in Laravel which is equivalent to the htmlentities PHP function. In my Form view and Controller I am trying to save a document that uses the e function which looks like this: Form view: {{ Form::text('client_name') }} Controller: $client = new Client; $client->client_name = e(Input::get('client_name')); $client->save(); Say I wrote <script type="text/javascript">alert('gotcha!');</script> into the client_name field. I then save it to database but when it

问题 I encountered a particular string (it's not completely printable, but you can see it below) that causes a htmlspecialchars() to return a zero-length string. Is there any way this can be fixed? $Stmnt = 'SELECT subject_name FROM bans WHERE id = 2321'; $Fetch = $Conn->query($Stmnt); if(!$Fetch) die('Could not query DB'); while($Row = $Fetch->fetch_array(MYSQLI_ASSOC)) { $RawName = $Row['subject_name']; $RawLen = strlen($RawName); echo('RAW NAME: ['.$RawName.']'.', LENGTH: ['.$RawLen.']'.'<br />
