Shazron, I just noticed this in the README for the plugin:
"However, since requests are made over http, your app's activity may be visible to others on the name wi-fi network.” Is this actually true? Why would traffic to localhost leave the device and be visible over the wifi? -- tommy-carlos williams On 20 November 2014 at 08:18:28, Homer, Tony (tony.ho...@intel.com) wrote: Ugh. Thanks for the additional information, Shazron. I had previously proposed adding a hook (by which I meant a delegate method) to CDVPluginResult (that would be called from - (CDVPluginResult*)initWithStatus:(CDVCommandStatus)statusOrdinal message:(id)theMessage) so that LocalWebServer could (blindly) detect and transform urls. It seems like it would help with this case, but not be generally useful for anything else… Tony On 11/19/14, 3:23 PM, "Shazron" <shaz...@gmail.com> wrote: >Ideally a general solution like you proposed should work, but I forgot to >mention that in this case, since we are talking about WKWebView, we can't >use NSURLProtocol since it is not supported in that framework [1][2] > >The only other general way I can see is to require explicit support in >plugins, they may have to call something in the >commandDelegate/viewController to transform a url, that can be set by >another plugin, in this case LocalWebServer (my revised proposal was a >'push' this is a 'pull'). > > >[1] https://issues.apache.org/jira/browse/CB-7049 >[2] http://www.openradar.me/18492325 > >On Wed, Nov 19, 2014 at 12:00 PM, Homer, Tony <tony.ho...@intel.com> >wrote: > >> If we are just talking about CB-8032, then I can see that this approach >>is >> cleaner for the file plugin. >> >> Regarding local web server plugin in general - what about other plugins >> such as camera? >> Doesn¹t there need to be a general solution that will provide >> compatibility between local web server plugin and any plugin that >>returns >> a file protocol URL? >> >> Tony >> >> On 11/19/14, 12:19 PM, "Shazron" <shaz...@gmail.com> wrote: >> >> >I commented on Ian's comment on CB-8032: >> > >> >>https://issues.apache.org/jira/browse/CB-8032?focusedCommentId=14216403&p >>a >> >>>ge=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comm >>>en >> >t-14216403 >> > >> >My goal was to have a loose coupling of this functionality (CDVFile >>need >> >not know about LocalWebServer at all) -- and Ian's comment of this >>change >> >is that would impact all CDVFileSystem instances makes this not an >>ideal >> >solution, what if you have two Cordova WebView instances, etc. >> > >> >My revised proposal requires CDVFileSystem to have a delegate that can >>be >> >set.
