Members

get_Headers

The HTTP response headers as received.

public HRESULT get_Headers(ICoreWebView2HttpResponseHeaders ** headers)

get_ReasonPhrase

The HTTP response reason phrase.

public HRESULT get_ReasonPhrase(LPWSTR * reasonPhrase)

The caller must free the returned string with CoTaskMemFree. See API Conventions.

get_StatusCode

The HTTP response status code.

public HRESULT get_StatusCode(int * statusCode)

GetContent

Get the response content asynchronously.

public HRESULT GetContent(ICoreWebView2WebResourceResponseViewGetContentCompletedHandler * handler)

The handler will receive the response content stream.

This method returns null if content size is more than 123MB or for navigations that become downloads or if response is downloadable content type (e.g., application/octet-stream). See add_DownloadStarting event to handle the response.

If this method is being called again before a first call has completed, the handler will be invoked at the same time the handlers from prior calls are invoked. If this method is being called after a first call has completed, the handler will be invoked immediately.
