cross-domain-policy

问题 I have a normal JSON feed that I am polling at a url (normalJSONfeed). I am getting the cross origin policy error each time. How can I alter the $.ajax function to get around this limitation when I do not have any way of changing the JSON feed (in other words I can not wrap the JSON feed in a function call). $.ajax({ type : "GET", dataType : "jsonp", url : '/normalJSONfeed', data : {} success: function(obj){ } }); 回答1: There is nothing that you can change in the code only that lets you

问题 i got two servers (prod.example.com and img.example.com) so on "prod" i process images from "img" using canvas in FF and Chrome all is Ok but in Safari i got this SECURITY_ERR: DOM Exception 18: An attempt was made to break through the security policy of the user agent. all images from "img" has Access-Control-Allow-Origin:* in headers so where is padla? 回答1: getImageData which you probably call will raise this if you try to access the one host from the other. You cannot go around this, the

问题 I have domain sub.example.com with configured restangular: RestangularProvider.setDefaultHeaders({ 'Content-Type': 'application/json', 'X-Requested-With': 'XMLHttpRequest' }); RestangularProvider.setDefaultHttpFields({ 'withCredentials': true }); Then I'm building other factory via: return Restangular.withConfig(function(RestangularProvider) { RestangularProvider.setBaseUrl('http://api.example.com'); }); And, obviously, getting error No 'Access-Control-Allow-Origin' header is present on the

问题 In my Flash app, I'm connecting to my server like this: Security.loadPolicyFile("xmlsocket://example.com:12860"); socket = new Socket("example.com", 12869); socket.writeByte(...); ... socket.flush(); At port 12860 I'm running a socket policy server, which (according to this document) correctly serves up my policy like this: 00000000 3c 70 6f 6c 69 63 79 2d 66 69 6c 65 2d 72 65 71 <policy- file-req 00000010 75 65 73 74 2f 3e 00 uest/>. 00000000 3c 63 72 6f 73 73 2d 64 6f 6d 61 69 6e 2d 70 6f

问题 I have a server script that I need to pass data to from the browser without reloading the page (aka ajax). The data is sensitive so should be sent via https. The page however is on the http layer. Because of same domain/protocol restriction, the browser doesn't allow this. I'm thinking of cheating the system a bit by dynamically creating image tags and call the script using the src tag such as: <img src="https://mydomain.com/mysecurescript/&data=to&pass=to&my=script" /> I'd like to know if

问题 Is it possible to disable cross domain security checks in Chromium while running dart application in Dart VM ? The problem is that it is running on its own port, and thus my application can't send asynchronous requests to my backend which is running on another port. Yes, I know that I can copy dart file to my backend and it will run just fine, but then I can't debug it. 回答1: If you're after a stop gap solution, just for debugging, you can use a flag to turn it off in chrome.

问题 I'm having an issue when attempting to include and access multiple XML documents in an XSL stylesheet. I'm assigning document nodes as variables and then attempting to access them in my xsl:template, similar to this: <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output method="xml" omit-xml-declaration="yes" /> <xsl:variable name="doc1" select="document('test.xml')" /> <xsl:template match="/"> <div> <span id="id_total"> <xsl:value-of select="count($doc1/

问题 I'm developing a jQuery plug-in that will be a connector for some REST API. The implementation is straight forward, but the same origin policy is definitely painfull. I need to perform mostly POST requests. I also tried to implement the OPTIONS method and returning (is python, but the meaning should be clear) def options(self): self.response.headers['Access-Control-Allow-Origin'] = self.request.host_url self.response.headers['Access-Control-Allow-Methods'] = 'POST, GET, OPTIONS' self.response

问题 Is there a "safe" way to check if the same origin policy applies to an URL before actually trying to use ajax methods? Here is what I have: function testSameOrigin(url) { var loc = window.location, a = document.createElement('a'); a.href = url; return a.hostname == loc.hostname && a.port == loc.port && a.protocol == loc.protocol; } This sort of works, but it’s kind of a manual guess based on the wikipedia article. Is there a better way of pre-checking cross domain allowance? jQuery is OK to

问题 Is it possible to set some http headers while http-redirect(302 or 307)? <? header("some-header: xxx"); header("Location: http://other.domain.com/foo.php",TRUE,307); ?> 回答1: You can basically set whatever http headers you want either as the server or the client. If you are indicating a redirect you should supply the Location header as your example suggests. You should also ensure that your response headers refer to that response rather than the resource that the client is being redirected to.
