WebView2Response class

The response side of a WebResourceRequested event. Fill in any of StatusCode, ReasonPhrase, Headers, or one of the content properties, and the runtime returns that synthesised response to the page instead of going to the network.

If the event handler does not touch the response (no property is written), the runtime falls through to its normal fetch — the in-flight request continues unchanged.

Private Sub Form_Load()
    WebView21.AddWebResourceRequestedFilter "https://api.example.com/*", wv2All
End Sub

Private Sub WebView21_WebResourceRequested( _
        ByVal Request As WebView2Request, _
        ByVal Response As WebView2Response)

    Response.StatusCode = 200
    Response.ReasonPhrase = "OK"
    Response.Headers.AppendHeader "Content-Type", "application/json"
    Response.ContentUTF8 = "{""greeting"":""hello from twinBASIC""}"
End Sub

Properties

ContentBytes

The response body as a byte array. Reading returns Empty when no body has been set; assigning installs an in-memory stream containing the bytes. Read / write.

Syntax: object.ContentBytes [ = bytes ]

bytes

A Byte() array.

ContentUTF8

The response body as a UTF-8 String — a convenience over ContentBytes that does the StrConv round-trip for you. Read / write.

Syntax: object.ContentUTF8 [ = text ]

text

A String that is converted to UTF-8 bytes before being installed as the response body.

Headers

The response’s HTTP headers as a WebView2ResponseHeaders collection — add or inspect headers here. Read-only at the property level (the collection itself is mutable).

ReasonPhrase

The HTTP reason phrase, e.g. "OK", "Not Found". String. Read / write.

StatusCode

The HTTP status code, e.g. 200, 404. Long. Read / write.
