![]() The problem is, I would like to avoid making a G-WAN servlet for returning static HTML, just to add the header. ![]() If you need to enable CORS on the server in case of localhost, you need to have the following on request header. A simple fix is to add the header: Access-Control-Allow-Origin: to the HTTP response. So, instead of using XMLHttpRequest we have to use HTML tags, the ones you usually use to load JavaScript files, in order for JavaScript to get data from another domain. JSONP is really a simple trick to overcome the XMLHttpRequest same domain policy. To do so, you need to cross domain boundaries. You’re on domain, and you want to make a request to domain t. JSONP ( JSON with Padding ) is a method commonly used to bypass the cross-domain policies in web browsers. To fix - in the API Gateway configuration - go to 'Gateway Responses', expand 'Default 4XX' and add a CORS configuration header there. You need to do something different when you want to do a cross-domain request. Also - if you happen to be getting a status code of 0 or 1 from a request running through API Gateway, this is probably your issue. So the browser is blocking it as it usually allows a request in the same origin for security reasons. You are doing an XMLHttpRequest to a different domain than your page is on. This is especially useful for authentication, and setting sessions. For every HTTP request to a domain, the browser attaches any HTTP cookies associated with that domain. CORS header ‘Access-Control-Allow-Origin’ missing'. This is happening because of the CORS (Cross Origin Resource Sharing). Your OPTIONS response should also include the header Access-Control-Allow-Headers: origin, content-type, accept to match the requested header. This should not be a huge effort nor should it be expensive (as you will only pay-per-use). You should include the header Access-Control-Allow-Credentials: true on the POST response as well. It is also the end-user that decides to install your P2 add-on, and as such, accept that it will proxy content from a 3rd party service (you should be clear about that in your add-on description).įor cloud add-ons, if you want to get content from a 3rd party service into your integration, you can use “serverless” products like AWS Lamba or GCP Cloud Functions to implement a proxy server using many popular coding languages. You can only make client-side requests to the same domain because this is the only way the browser can determine that the resources is loaded from a connection that is trusted by the end-user (because they decided to load the application from that domain). This is a basic security issue which all browsers have implemented, and it helps keep the internet safe. This is just how XmlHttpRequest (and in extend maybe the internet) works. So… the problem is actually not specific to Jira.
