サーバーからのファイルのロード
サーバーからファイルをロードするには、サーバーへのリクエストを作成する必要があります (AppServerURL + “/FlexiCapture12/Server/FileService/v1”) 。リクエストメソッド は POST にし、contents は application/x-www-form-urlencoded 型である必要があります。結果は新しいファイルに記録する必要があります。 リクエスト本文:"Action=Load" +"&sessionId=" + session + "&objectType=" + objectType + "&projectId=" + projectId + "&batchId=" + batchId + "&objectId=" + objectId + "&version=" + version + "&streamName=" + streamName
static private CredentialCache basicAuthenticationCredentialCache = null;
public static List<byte> POSTLoadFile(string AppServerURL, int session, int projectId, int batchId, int objectType, int objectId, int version, int parentId, string streamName)
{
List<byte> result = new List<byte>();
HttpWebResponse response = null;
Stream responseStream = null;
BinaryReader reader = null;
try
{
// リクエストの作成
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(AppServerURL + "/FlexiCapture12/Server/FileService/v1");
request.Method = "POST";
// Webサービスへの接続時の認証設定
if (basicAuthenticationCredentialCache != null)

// レスポンスの受信

}

サーバーへのファイルのアップロード
既存のファイルを開き、そこからデータを読み取る必要があります (“content” 文字列は、Encoding.Default を使用してバイナリファイルから取得する必要があります) 。 ファイルを保存するには、サーバーへのリクエストを作成する必要があります (AppServerURL + “/FlexiCapture12/Server/FileService/v1”) 。リクエスト メソッドは POST、contents は multipart/form-data 型にする必要があります。 リクエスト本文："\r\n--" + requestId + "\r\ncontent-disposition: form-data; name=\"Action\"\r\n\r\nSave" +
"\r\n--" + requestId + "\r\ncontent-disposition: form-data; name=\"objectType\"\r\n\r\n" + objectType +

チェックサムの取得
チェックサムを取得するには、サーバーへのリクエストを作成する必要があります (AppServerURL + “/FlexiCapture12/Server/FileService/v1”) 。リクエストメソッドは POST、contents の型は application/x-www-form-urlencoded にする必要があります。 リクエスト本文:"Action=Checksum" + "&sessionId=" + session + "&objectType=" + objectType + "&projectId=" + projectId + "&batchId=" + batchId + "&objectId=" + objectId + "&version=" + version + "&streamName=" + streamName

分割ロード (既存ファイルの変更)
重要！ 変更できるのは、サーバー上にすでに存在するファイルのみです。 ファイルを変更するには、サーバーへのリクエストを作成する必要があります (AppServerURL + “/FlexiCapture12/Server/FileService/v1”) 。リクエストメソッドは POST で、内容の型は multipart/form-data である必要があります。 リクエスト本文:"\r\n--" + requestId + "\r\ncontent-disposition: form-data; name=\"Action\"\r\n\r\nAppend" +
