To handle POST data in the OnNavigate event when using Delphi TEdgeBrowser, you can use the following steps:
Here is an example code snippet:
procedure TForm1.EdgeBrowser1Navigate(Sender: TObject; const Browser: IDispatch; const frame: IDispatch; const url: OleVariant);
var
WebRequest: ICoreWebView2WebResourceRequest;
RequestData: IRequestData;
RequestDataAsStream: IRandomAccessStream;
Reader: IInputStream;
Buffer: TBytes;
Charset: string;
begin
EdgeBrowser1.CoreWebView2.Environment.GetWebResourceRequest(Browser, url, @WebRequest);
if WebRequest <> nil then
begin
if WebRequest.Method = 'POST' then
begin
RequestData := WebRequest.PostData;
if RequestData <> nil then
begin
RequestDataAsStream := RequestData.GetAsync().GetResults();
Reader := TDataReader.Create(RequestDataAsStream);
SetLength(Buffer, RequestDataAsStream.Size);
Reader.Read(Buffer, Length(Buffer), @Length(Buffer));
Charset := RequestData.Headers.GetValue('Content-Type').Split([';'])[1].Split(['='])[1];
// Process the form data as necessary
end;
end;
end;
end;
Note that you may need to adjust the code based on your specific requirements and the structure of the POST data.
