Load local file error

I cant load a local file because http is only allowed.

XMLHttpRequest cannot load file:///var/mobile/... Cross origin requests are only supported for HTTP.

How can i allow to load local files in an app? Thanks, David

The reason I ask is that there is a known issue which prevents local XHRs when using the WKWebView plugin: [CB-10143] Local file:// url XmlHttpRequests are not allowed in WKWebViewEngine - ASF JIRA

    Hi David,

    Have you enabled the WKWebView plugin for your app? If so, can you try creating a new app with this plugin disabled?

      Hi. Thanks for the example.

      When i try your code I get again the following error:

      [Error] XMLHttpRequest cannot load file:///var/mobile/Containers/Data/Application/C500078F-1FD2-43EC-A418-BBF0686E9FBB/Library/Caches/d00a72956e898ba4b1f05bd995912e49/deea684712127650165f68d34ccf76af/folio/data.json. Cross origin requests are only supported for HTTP.

      (anonymous function) (index.js:66)

      It works in the Adobe preflight app, but not in our test app.

        Hi David,

        I've put together a simple example that shows how you can read JSON data from a local file:

        GitHub - blefebvre/aemm-read-local-file: Example article that shows how you can read a local file on device

        The file being read can be found here: aemm-read-local-file/data.json at master · blefebvre/aemm-read-local-file · GitHub

        And the code which is reading it using an XHR is here: aemm-read-local-file/index.js at master · blefebvre/aemm-read-local-file · GitHub

        When you run the app via either the aemm CLI or AEM Mobile Preflight, you will see the message from the file is displayed in the app:

        Hope this helps.

          Can you paste the code that your using to try to load the content.  Also paste the URL of the content that your trying to load.
