アプリのログインページを作成しています。クレデンシャルの詳細は DB に保存されます。だから私はASP.Netミドルウェアサービスを作っています。
以前は、URL STRING に詳細を追加するリクエストを送信するために GET メソッドを実行していました (これは今は必要ありません)。POST メソッドを実行したいと考えています。そのための非常に良いリンクを1つ見つけましたが、正しく実行したかどうか、またはASP.netの同僚が機能していないために間違いを犯したかどうかはわかりません。
資格情報、つまりユーザー名とパスワードが正しい場合、サービスは次のような XML を返します。
<result>
success
</result>
そうでない場合は失敗します。
ですから、このコードが正しいかどうか、そうでない場合は何が間違いかを教えてください....お時間をいただきありがとうございます。
