は、今私は問題が正常にデバッガによって初期化されませhConnect知っている、と私は疑問に思うなぜ失敗したか、感謝C++ NPAPI WinHttpConnectは

errcodeは12005 – bajie

です。これは 'ERROR_INTERNET_INVALID_URL'です。URLは無効です。 wcharへの変換が正しく行われていますか?また、 's2ws'の戻り値を使用している方法は少しスケッチです。それが働くことが保証されていれば私は覚えていません。 – user786653

答えて

私はPythonでこのエラーを見ましたが、解決策はutf-16エンコーディングでurl文字列を渡すことでした。

試してみるwstring uri; ワイドバージョンでは、変換する必要はありません。
