Public Sub AddWebResourceRequestedFilter (uri As String, ResourceContext As CoreWebView2WebResourceContext)

Parameters

uri

String

An URI to be added to the WebResourceRequested event.

ResourceContext

CoreWebView2WebResourceContext

A resource context filter to be added to the WebResourceRequested event.

Remarks

A web resource request with a resource context that matches this filter's resource context and a URI that matches this filter's URI wildcard string will be raised via the WebResourceRequested event.

The uri parameter value is a wildcard string matched against the URI of the web resource request. This is a glob style wildcard string in which a * matches zero or more characters and a ? matches exactly one character. These wildcard characters can be escaped using a backslash just before the wildcard character in order to represent the literal * or ?.

The matching occurs over the URI as a whole string and not limiting wildcard matches to particular parts of the URI. The wildcard filter is compared to the URI after the URI has been normalized, any URI fragment has been removed, and non-ASCII hostnames have been converted to punycode.

Specifying a nullptr for the uri is equivalent to an empty string which matches no URIs.

	URI Filter String	Request URI	Match	Notes
	*	https://contoso.com/a/b/c	Yes	A single * will match all URIs
	*://contoso.com/*	https://contoso.com/a/b/c	Yes	Matches everything in contoso.com across all schemes
	*://contoso.com/*	https://example.com/?https://contoso.com/	Yes	But also matches a URI with just the same text anywhere in the URI
	example	https://contoso.com/example	No	The filter does not perform partial matches
	*example	https://contoso.com/example	Yes	The filter matches across URI parts
	*example	https://contoso.com/path/?example	Yes	The filter matches across URI parts
	*example	https://contoso.com/path/?query#example	No	The filter is matched against the URI with no fragment
	*example	https://example	No	The URI is normalized before filter matching so the actual URI used for comparison is https://example.com/
	*example/	https://example	Yes	Just like above, but this time the filter ends with a / just like the normalized URI
	https://xn--qei.example/	https://❤.example/	Yes	Non-ASCII hostnames are normalized to punycode before wildcard comparison
	https://❤.example/	https://xn--qei.example/	No	Non-ASCII hostnames are normalized to punycode before wildcard comparison
