To let browsers check this field, the web server must explicitly specify this header as exposed.</p> <p>This can be enabled in the configuration of the CORS filter for sal-rest-connector. See attached diff.</p> <p>Operating System: Linux<br/> Platform: PC</p> CONTROLLER-278

Unable to use websocket notifications from browsers

After GET request on stream link I got following response</p> <p>HTTP/1.1 200 OK<br/> Server: Apache-Coyote/1.1<br/> Cache-Control: private<br/> Expires: Thu, 01 Jan 1970 01:00:00 CET<br/> Location: <a href="http://localhost:8185/opendaylight-inventory:nodes/datastore=CONFIGURATION/scope=BASE" class="external-link" target="_blank" rel="nofollow noopener">http://localhost:8185/opendaylight-inventory:nodes/datastore=CONFIGURATION/scope=BASE</a><br/> Content-Length: 0<br/> Date: Fri, 26 Sep 2014 05:41:39 GMT</p> <p>So please specify more details about this problem or steps how to reproduce it.</p> <p>I ran the attached script in Chrome when I reported the bug. (Note, it uses d3.js).</p> <p>If I remember correctly, when calling getResponseHeader("Location"), Chrome rejected and reported that it is unsafe.</p> <p>Attachment gui2.tar.gz has been added with description: JS to reproduce the bug</p> <p>I wasn't able to replicate it via your java script. I prepared lightweight version (see below) but neither it was possible to replicate.<br/> function httpGet()<br/> {<br/> var xmlHttp = null;<br/> xmlHttp = new XMLHttpRequest();<br/> xmlHttp.open( "GET", <br/> "http://localhost:8080/restconf/streams/stream/opendaylight-inventory:nodes/datastore=CONFIGURATION/scope=BASE", <br/> true );<br/> xmlHttp.send( null );<br/> xmlHttp.onreadystatechange = function() {<br/> if(this.readyState == 2) </p> { alert(this.getAllResponseHeaders()); } <p> } <br/> }</p> <p>Therefore I prepared patch as you suggested.<br/> <a href="https://git.opendaylight.org/gerrit/11608" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/11608</a></p> <p>It's quite possible this has been fixed since; there have been so many refactorings in the past six months.</p> <p>I don't have the tools right now to test if this has been fixed or if the patch is necessary.</p> <p>If you see the bug gone, just close the ticket. If anyone experiences it again, it'll be here for reopening...</p> <p>as I wrote I couldn't replicate this issue. If you have time please test it.</p> Blocks CONTROLLER-287 CONTROLLER-451 Development External issue ID 671 External issue URL ODL SR Target Milestone Rank 0|i02jev:
