WebDav - NextCloud

[Carsten Hölscher]

Hier mal der Inhalt der dfm-Datei und 2 Beispiele wie ich eine Datei und eine Auflsitung des Serverinhalts mache:

Code:

  object IdConnectionIntercept: TIdConnectionIntercept
    Left = 512
    Top = 64
  end

  object IdSSLIOHandlerSocketOpenSSL: TIdSSLIOHandlerSocketOpenSSL
    Intercept = IdConnectionIntercept
    MaxLineAction = maException
    Port = 0
    DefaultPort = 0
    SSLOptions.Method = sslvTLSv1_2
    SSLOptions.SSLVersions = [sslvTLSv1_2]
    SSLOptions.Mode = sslmUnassigned
    SSLOptions.VerifyMode = []
    SSLOptions.VerifyDepth = 0
    Left = 456
    Top = 48
  end

  object IdWebDAV: TIdWebDAV
    Intercept = IdConnectionIntercept
    IOHandler = IdSSLIOHandlerSocketOpenSSL
    OnWork = IdWebDAVWork
    OnWorkBegin = IdWebDAVWorkBegin
    OnWorkEnd = IdWebDAVWorkEnd
    HandleRedirects = True
    ProxyParams.BasicAuthentication = False
    ProxyParams.ProxyPort = 0
    Request.CacheControl = 'no-cache'
    Request.Connection = 'Keep-Alive'
    Request.ContentEncoding = 'utf-8'
    Request.ContentLength = -1
    Request.ContentRangeEnd = -1
    Request.ContentRangeStart = -1
    Request.ContentRangeInstanceLength = -1
    Request.Accept = 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8'
    Request.AcceptCharSet = 'utf-8'
    Request.BasicAuthentication = True
    Request.UserAgent = 'Mozilla/3.0 (compatible; Indy Library)'
    Request.Ranges.Units = 'bytes'
    Request.Ranges = <>
    HTTPOptions = [hoForceEncodeParams]
    Left = 400
    Top = 32
  end
  
  
  // datei öffnen
  stream:=TMemoryStream.Create;
  ss:=TStringList.Create;

  IdWebDAV.Request.URL:=....;
  IdWebDAV.Request.Username:=....;
  IdWebDAV.Request.Password:=....;
  IdWebDAV.Request.CustomHeaders.Clear;
  
  try
    IdWebDAV.Get(<URL der Datei>, stream);
    stream.Position:=0;
    ss.LoadFromStream(stream);
  except
    on E:Exception do MessageDlg(E.Message + ' ('+<URL der Datei>+')', mtWarning, [mbOK], 0);
  end;
  ss.Free;
  stream.Free;
  
  // dateiverzeichnis abfragen
  WebDAVXml:IXMLDocument ;
  xmlResponse:=TMemoryStream.Create;  
  IdWebDAV.DAVPropFind(Serverpfad, nil, xmlResponse, '4', 1, 4); // Die '1' lädt das aktuelle Verzeichnis, die Tiefe kann hier bestimmt werden
  WebDAVXml:=TXmlDocument.Create(nil);
  try
    WebDAVXml.LoadFromStream(xmlResponse);
   ... xml analysieren
  except
    .... //xml-Fehler
  end;   
  xmlResponse.free;
