CORS policy: Cross origin requests

[aicameron10]

Access to XMLHttpRequest at 'file:///android_asset/book.epub' from origin
has been blocked by CORS policy: Cross origin requests
Android 33

How can this be solved ?

code snippets:
val webViewState = rememberWebViewStateWithHTMLFile(
fileName = "index.html"
)

webViewState.webSettings.apply {
isJavaScriptEnabled = true
logSeverity = KLogSeverity.Debug
androidWebSettings.apply {
isAlgorithmicDarkeningAllowed = true
safeBrowsingEnabled = true
allowFileAccess = true
}
iOSWebSettings.apply { }
}

Hi! According to this post, we may need to set allowFileAccessFromFileURLs and allowUniversalAccessFromFileURLs to true. However, it is not currently open for customization. I apologize for any inconvenience caused by this issue.

Thank you for your help! I just discovered that we need to configure WKWebViewConfiguration in order to grant it access to the file.

I have fixed it and pushed to that branch. Could you please have a test on it? You just need to set webSettings like that:

webViewState.webSettings.apply {
        isJavaScriptEnabled = true
        logSeverity = KLogSeverity.Debug
        allowFileAccessFromFileURLs = true
        allowUniversalAccessFromFileURLs = true
        androidWebSettings.apply {
            isAlgorithmicDarkeningAllowed = true
            safeBrowsingEnabled = true
            allowFileAccess = true
        }
    }

Thanks for your help again!

Hi
Will this be added to 1.8.0 ?

It should be added to 1.7.2 and will be released next week.
