検索してみたところ、誰かがマルチパート フォーム アップローダーを作成していることがわかりました。

1つ間違っていましたが、URLのすべての-おそらく-POST値を転送しました..Webアプリケーションが気に入らない-どういうわけか。

全部行きました

POST /index.php?page=post&s=add&title=test&tags=testtags HTTP/1.1

そして、ファイルを投稿コンテンツに追加しただけです。

私はブラウザで送信しようとしましたが、これが出てきました:

画像データのバイトを IMGDATA に置き換えて短くしました。

このアップロードは承認されました。そこで、後で紹介する VB.NET コードでこれを真似てみました。これが出てきました：

しかし、これは受け入れられませんでした。それで、何が問題だったのですか？また、2つの余分な（--）を別の場所に置いてみました..そして、結局、何も変わりませんでした。これは、送信に使用した VB.NET コードの切り抜きです。Uploader.Start は、グローバル変数を使用するスレッドを通じてアップロード プロセスを開始します。

誰でもこれで私を助けてくれることを願っています。何が悪いのかわかりません。

リダイレクトとともに「アップロード成功」メッセージを返す必要がありますが、アップロード ページ自体のみが返されます。ネットワークスニファで確認しました。

System.Net.WebClient代わりにクラスを見てみませんか？http://msdn.microsoft.com/en-us/library/system.net.webclient.aspxこの方法では、POST データのフォーマットについて心配する必要はありません。http WebClient.UploadFile(): //msdn.microsoft.comに電話するだけです。 /en-us/library/36s52zhs.aspx
