Posted on by MG-04060224-0 8
I created new table with blob field and API page for this table. Now I want to intercept POST request and convert base64 string to blob and save the record. Is there anyway to accomplish this? Or any better method for saving file in business central, custom made table from API request

    Hi,
     
    You can try this procedure when you are getting Base64 text from API url.
        local procedure ConverBase64Text(FileContent: text)
    var
        BaseConvert: Codeunit "Base64 Convert";
        TempBlob: Codeunit "Temp Blob";
        OutStr: OutStream;
        RecRef: RecordRef;
    begin
        if FileContent = '' then
            exit;
        RecRef.Open(Database::<TargetTable>);
        RecRef.GetTable(<TargetTable>);
        TempBlob.CreateOutStream(OutStr);
        BaseConvert.FromBase64(FileContent, OutStr);

        TempBlob.ToRecordRef(RecRef, <TargetTable>.FieldNo(<BlobField>));
        RecRef.SetTable(<TargetTable>);
        RecRef.Close();
    end;
