Question

ブラジルでのフライトのフライト監視ソフトウェアを開発していますが、Web サイトからフライトデータを正常に受信するのに問題があります。それは ASP.NET にあり、実際にデータを表示する前に、複数の要求を満たす必要があると思います。

私はすでに ASP.NET 固有の変数 (EVENTVALIDATION や VIEWSTATE など) を取得しており、複数の要求 (1 つは空港を送信し、もう 1 つは投稿を送信) を送信していますが、それでもうまくいきません。

空港と航空会社を選択するページはhttp://voos.infraero.gov.br/voos/index.aspxですが、データはここに表示されていますhttp://voos.infraero.gov.br/voos/index_2 .aspx .

まだデバッグ中のため、コードは最適化されていません。助けてくれてありがとう。
