cross-domain

问题 I'm trying to access web service from my angular service with cross-origin related headers set. But still, I'm not able to access the web service. The browser keeps saying, Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:4200' is therefore not allowed access. The response had HTTP status code 403. I'm able to access the same URL in the browser (chrome) and postman but not in

问题 The goal is to access and edit a SVG document rendered via an iFrame with a Base64 data URI. Accessing the SVG document yields a cross-origin error, even though the iFrame is rendered locally via a data URI. What's the right way to access a SVG document rendered via an iFrame with a data URI? jquery.min.js:2 Uncaught DOMException: Blocked a frame with origin "http://localhost:3000" from accessing a cross-origin frame. at new w.fn.init (https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery

问题 I basically need to perform a GetListItems from a SharePoint list on a different server. I have tried different codes but they all error out. Can someone look at what I have and see if it's wrong or if it's just not possible? I get the Error alert then an xData.ResponseText alert as 'undefined'. Nothing after that. The server where I'm running the code is server3.intranet.com. Thank you. var soapEnv = "<soapenv:Envelope xmlns:soapenv='http://schemas.xmlsoap.org/soap/envelope/'> \ <soapenv

问题 Maybe I'm just not understanding this right, but this doesn't seem to make sense to me. I have an MVC4 project exposing an ASP.NET WebApi. It works great making calls to the API within that project, but obviously making calls to it from another running project (on another port) requires cross-site scripting. But here's my question: Doesn't this defeat the purpose of an API? If I want to make calls to the reddit API from my site, the fact that this is considered cross-site scripting makes it

问题 I would like to call and show a page from another domain to my domain using ajax/javascript. I would like to hide the original url of the page. (Example in the case of surveymoneky, I can load the survey page in my web site with out showing the surverymonkyes url.) How can I do it ? Thanks in advance.. Regards, Sunil 回答1: Due to the SOP (same origin policy) implemented in browsers, you can only retrieve information from another domain using Ajax if the other domain allows that by setting the

问题 I have a server-side API on the domain api.example.com User is visiting www.website.com where a script makes an XmlHttpRequest to api.example.com and gets a response with a cookie. It appears the API's response cookie is not honored by the HTTP agent. I'm aware of the non-cross-domain-leaking-cookie policy, but I thought the domain here would be api.example.com . Seems I guessed wrong. Is there some other way that my API on api.example.com could remember user data from one site to another? If

问题 Make it Using javascript API. On their site works fine, but locally cant send cross-domain request. Where is the problem? request is XMLHttpRequest cannot load http://pubsub.pubnub.com/publish/KEY//0/broadcast/0/%224444444444444%22. Origin localhost:3000 is not allowed by Access-Control-Allow-Origin. 回答1: Using PubNub Everywhere! Even localhost and file:/// Using PubNub on localhost is super easy!

问题 I have a web page, designed as a popup window that must be hosted by many external web sites. When the user clicks on a button in the hosting web page, the button should cause my iFrame to display. The user then interacts with my iFrame'd page to complete a specific task and eventually clicks the "close" button within my page and the frame becomes hidden again. However, because the two documents reside in different domains (and must do so), I am running up against browser security

问题 First off, I am working on a local EaselJS/CreateJS project, only to test some sprite and mouse interaction. I have added a simple sprite image to the stage, and I called it "enemy1": //Create the enemy sprite and add it to the stage var enemy_image = new Image(); enemy_image .src = "enemy_sprite.png"; var enemy1 = new createjs.Bitmap(enemy_image); enemy1 .x = 0; enemy1 .y = 0; stage.addChild(enemy1); Using this code, I want to show an alert every time the user clicks on it: enemy1.on("click"

问题 In testing out an endpoint for CORS capability and I'm curious if someone can explain the following difference in results while using curl: First, I tried the following: $ curl -i https://api.github.com -H "Origin: http://github.com" -X OPTIONS Which resulted in a successful response giving me what I'd expect in regards to an Access-Control-Allow-Origin header, among others. Secondly, I tried this: $ curl -i https://api.github.com -H "Origin: http://jamesdh.github.com" -X OPTIONS Which
