Serve webviews from the same origin
|
|
|
|
Normally webviews are served from vscode-webview.net but we would rather them be
|
|
self-hosted.
|
|
|
|
When doing this CSP will block resources (for example when viewing images) so
|
|
add 'self' to the CSP to fix that.
|
|
|
|
Additionally the service worker defaults to handling *all* requests made to the
|
|
current host but when self-hosting the webview this will end up including the
|
|
webview HTML itself which means these requests will fail since the communication
|
|
channel between the webview and the main thread has not been set up yet as the
|
|
webview itself is not ready yet (it has no HTML and therefore no script either).
|
|
Since this code exists only for the authentication case we can just skip it when
|
|
it is served from the current host as authentication is not a problem if the
|
|
request is not cross-origin.
|
|
|
|
To test, open a few types of webviews (images, markdown, extension details, etc).
