[GitHub] [cordova-ios] jurihahn opened a new issue #827: WkWebView break iframe working from file://
jurihahn opened a new issue #827:
URL: https://github.com/apache/cordova-ios/issues/827
# Bug Report
## Problem
if i use WkWebView loading HTML file to iframe I get error:
WebPageProxy::Ignoring request to load this main resource because it is outside the sandbox
its happened only if I try to load HTML file not from app self. I download a HTML file and start it from App-Data folder "cordova.file.dataDirectory".
### What is expected to happen?
iframe should load HTML page from "file://" protocol. May be its need an Option to allow some URL's
### What does actually happen?
Error: WebPageProxy::Ignoring request to load this main resource because it is outside the sandbox
## Information
I try to switch from UIWebView to WkWebView and this is last Problem.
I have found information about this Problem https://stackoverflow.com/questions/40123321/wkwebview-run-local-html-in-document-received-an-unexpected-url-from-the-web-p
but how can I provide my URL to this function to allow loading?
this is added to config
<allow-navigation href="*" />
<allow-navigation href="file://*" />
<allow-intent href="file://*" />
<allow-intent href="*" />
### Command or Code
create HTML File in App-Data "cordova.file.dataDirectory" and load this file in iFrame NOT InAppBrowser
### Environment, Platform, Device
iPhone iOS 13.4.1
### Version information
<!--
What are relevant versions you are using?
For example:
Cordova 9.0.0,
Cordova iOS 5.1.1,
cordova-plugin-file 6.0.2,
Xcode 11.4.1,
-->

I ran into a similar issue with migration to WkWebView. (Additionally, I needed iframes to run as same origin, despite WkWebView treating anything in file:// as unique-origin.) This is my workaround:
```
function frameEl_injectHtml(frameEl, injectHtml) {
// frameEl must exist in DOM before its contentWindow is accessible.
if (!frameEl.contentWindow) { alert("frameInjectHtml() but frameEl not (yet or anymore) in DOM."); return; }
frameEl.contentWindow.document.open('text/htmlreplace');
frameEl.contentWindow.document.write(injectHtml);
frameEl.contentWindow.document.close();
}
// Create <frame>, insert into DOM, and inject content.
var frameHtml = "<html><head></head>" +
"<body style='background-color:#eee; color:#000;'>" +
"iframe body" +
"<script>window.parent.alert('iframe even same-origin as parent.');</script>" +
"</body></html>";
var frameEl = document.createElement('iframe');
frameEl.src = "about:blank";
document.body.appendChild(frameEl);
frameEl_injectHtml(frameEl, frameHtml);
```

I ran into a similar issue with migration to WkWebView. (Additionally, I needed iframes to run as same origin, despite WkWebView treating anything loaded via `src="file://..."` as unique-origin.) This is my workaround. It inserts html content directly into the iframe rather than using `src="..."` attribute, so no references to external files.
```
function frameEl_injectHtml(frameEl, injectHtml) {
// frameEl must exist in DOM before its contentWindow is accessible.
if (!frameEl.contentWindow) { alert("frameInjectHtml() but frameEl not (yet or anymore) in DOM."); return; }
frameEl.contentWindow.document.open('text/htmlreplace');
frameEl.contentWindow.document.write(injectHtml);
frameEl.contentWindow.document.close();
}
// Create <frame>, insert into DOM, and inject content.
var frameHtml = "<html><head></head>" +
"<body style='background-color:#eee; color:#000;'>" +
"iframe body" +
"<script>window.parent.alert('iframe even same-origin as parent.');</script>" +
"</body></html>";
var frameEl = document.createElement('iframe');
frameEl.src = "about:blank";
document.body.appendChild(frameEl);
frameEl_injectHtml(frameEl, frameHtml);
