I am using ISAPI rewrite on a project and would like to know if it is possible to publish a .htaccess file from Tridion?
I have tried creating a Page Template with the .htaccess extension but can't create a page with no name.
Any ideas?
Could I use a C# TBB to change the page name?
I would also choose to use a binary to achieve this, but if you want to manage the htaccess file using text, rather than as a multimedia component, you can push a binary into your package using the following technique:
1) Push the text of the Htaccess file into the package with an accessible name (i.e. Binary_Text)
2) Use code similar to the following to create a text file from the text in the variable and add it to the package
class publishStringItemAsBinary : ITemplate
{
public void Transform(Engine engine, Package package)
{
TemplatingLogger log = TemplatingLogger.GetLogger(typeof(publishStringItemAsBinary));
TemplateUtilities utils = new TemplateUtilities();
System.IO.Stream inputStream = null;
try
{
string strInputName = package.GetValue("InputItem");
string strFileName = package.GetValue("strFileName");
string sg_Destination = package.GetValue("sg_Destination");
string itemComponent = package.GetValue("mm_Component");
inputStream = new MemoryStream(Encoding.UTF8.GetBytes(package.GetValue(strInputName)));
log.Debug("InputObject:" + strInputName);
log.Debug("Filename for binary:" + strFileName);
log.Debug("Destination StructureGroup:" + sg_Destination);
Publication contextPub = utils.getPublicationFromContext(package, engine);
TcmUri uriLocalSG = TemplateUtilities.getLocalUri(new TcmUri(contextPub.Id), new TcmUri(sg_Destination));
TcmUri uriLocalMMComp = TemplateUtilities.getLocalUri(new TcmUri(contextPub.Id), new TcmUri(itemComponent));
StructureGroup sg = (StructureGroup)engine.GetObject(uriLocalSG);
Component comp = (Component)engine.GetObject(uriLocalMMComp);
String sBinaryPath = engine.PublishingContext.RenderedItem.AddBinary(inputStream, strFileName, sg, "nav", comp, "text/xml").Url;
//Put a copy of the path in the package in case you need it
package.PushItem("BinaryPath", package.CreateStringItem(ContentType.Html, sBinaryPath));
}
catch (Exception e)
{
log.Error(e.Message);
}
finally
{
if (inputStream != null)
{
inputStream.Close();
}
}
}
}
I think the code is pretty self explanatory. This publishes a binary of type text/xml, but there should be no issue converting it to do a plain text file.
I think you can use multimedia component to store your .htaccess. Even if you will not be able to upload file without name (Windows limitation), you will be able to change filename later, by modifying BinaryContent.Filename property of multimedia component. You can then publish this component seperately, or use AddBinary method in one of your templates.
There's also a user schema where you can change some other rules: "\Tridion\bin\cm_xml_usr.xsd", but you will not be able to allow empty filenames

Mode of publishing - static
I'm trying to publish images, but the issue is whenever I publish those images, their TCM URI is appended to their name (i.e if image name is example and its TCM URI is like tcm:1-115, image filename becomes example_tcm1-115).
I have written the following code:
public void Transform(Engine engine, Package package)
{
Filter MMCompFilter = new Filter();
MMCompFilter.Conditions["ItemType"] = Tridion.ContentManager.ItemType.Component;
Folder folder = engine.GetObject("tcm:1-1-2") as Folder;
foreach (Component MMcomp in folder.GetItems(MMCompFilter))
{
Binary binary = engine.PublishingContext.RenderedItem.AddBinary(MMcomp);
String binaryurl = binary.Url;
char[] array = binaryurl.ToCharArray();
Array.Reverse(array);
string obj = new string(array);
string final = newImagepath(obj);
char[] array2 = final.ToCharArray();
Array.Reverse(array2);
string obj2 = new string(array2);
package.PushItem("Image", package.CreateHtmlItem(obj2));
}
public string newImagepath(string filePath)
{
int formatIndex =filePath.IndexOf(".");
string format= filePath.Substring(0,formatIndex);
int finalPath=filePath.IndexOf("_");
string newPath=filePath.Substring((finalPath+1));
return (format+"."+newPath);
}
}
I want to publish images without the TCM URI appended to it. Plz suggest how can it be done.
Chris Summers wrote a very nice article on this very topic http://www.urbancherry.net/blogengine/post/2010/02/09/Unique-binary-filenames-for-SDL-Tridion-Multimedia-Components.aspx
It is basically a very simple thing to fix, but can have huge consequences which you should be aware of!
You can only publish a binary with a certain file-name in a single location once (and a binary can only be published to a single location on the presentation server, unless you publish it as a variant). However, in the CMS it is very easy to create Multimedia Components with the same binary file-name in different folders, which if they get published to the same location will be in conflict. That is why by default SDL Tridion appends the TCM URI to the filename to make it unique.
Simplest is always best.
In your TBB, just push the individual images to the package:
package.PushItem(package.CreateMultimediaItem(component.Id));
Then use the "PublishBinariesInPackage" TBB to publish these images to your presentation server.
You can use the RenderedItem.AddBinary method for this goal. Some of the overloaded versions of the method allows to publish an image as a stream, and pass any file name. For example:
public Binary AddBinary(
Stream content,
string filename,
string variantId,
string mimeType
)
I have an ASP.NET MVC3 application and I want to link_to an image file (png, jpeg, gif, etc), and when user clicks on it, the file goes to download, instead of the browser shows it; is there any way to do this?
take your link something like this:
#Html.ActionLink(
"Download Image", // text to show
"Download", // action name
["DownloadManager", // if need, controller]
new { filename = "my-image", fileext = "jpeg" } // file-name and extension
)
and action-method is here:
public FilePathResult Download(string filename, string fileext) {
var basePath = Server.MapPath("~/Contents/Images/");
var fullPath = System.IO.Path.Combine(
basePath, string.Concat(filename.Trim(), '.', fileext.Trim()));
var contentType = GetContentType(fileext);
// The file name to use in the file-download dialog box that is displayed in the browser.
var downloadName = "one-name-for-client-file." + fileext;
return File(fullPath, contentType, downloadName);
}
private string GetContentType(string fileext) {
switch (fileext) {
case "jpg":
case "jpe":
case "jpeg": return "image/jpeg";
case "png": return "image/x-png";
case "gif": return "image/gif";
default: throw new NotSupportedException();
}
}
UPDATE:
in fact, when a file is sending to a browser, this key/value will be generated in http-header:
Content-Disposition: attachment; filename=file-client-name.ext
which file-client-name.ext is the name.extension that you want the file save-as it on client system; for example, if you want to do this in ASP.NET (none mvc), you can create a HttpHandler, write the file-stream to Response, and just add the above key/value to the http-header:
Response.Headers.Add("Content-Disposition", "attachment; filename=" + "file-client-name.ext");
just this, enjoy :D
Well technically your browser is downloading it.
I don't think you can directly link to an image, and have the browser prompt to download.
You could try something where instead of linking directly to the image, you link to a page, which serves up the image in a zip file perhaps - which of course would prompt the download to occur.
Yes, you can.
Now, you'll need to customize this to suit your needs, but I created a FileController that returned files by an identifier (you can easily return by name).
public class FileController : Controller
{
public ActionResult Download(string name)
{
// check the existence of the filename, and load it in to memory
byte[] data = SomeFunctionToReadTheFile(name);
FileContentResult result = new FileContentResult(data, "image/jpg"); // or whatever it is
return result;
}
}
Now, how you read that file or where you get it from is up to you. I then created a route like this:
routes.MapRoute(null, "files/{name}", new { controller = "File", action = "Download"});
My database has a map of identifiers to files (it's actually more complex than this, but I am omitting that logic for brevity), I can write urls like:
"~/files/somefile"
And the relevant file is downloaded.
I don't think this is possible but a simple message saying right click to save image would suffice I think.
Consider:
strPath= c:\images\gallery\add.gif
I need to rename this file from add.gif to thumb1.gid, and I should write one command method, whatever the file name. We need to
replace that name with this like below.
string strfilename = **"thumb"**
****Result thum.gif**
strPath= c:\images\gallery\thum.gif **
You have several problems, looking up the value in the XML file, and renaming the file.
To look up the number corresponding to Gallery2 or whatever, I would recommend having a look at Stack Overflow question How to implement a simple XPath lookup which explains how to look up nodes/values in an XML file.
To rename a file in .NET, use something like this:
using System.IO;
FileInfo fi = new FileInfo("c:\\images\\gallery\\add.gif");
if (fi.Exists)
{
fi.MoveTo("c:\\images\\gallery\\thumb3.gif");
}
Of course, you would use string variables instead of string literals for the paths.
That should give you enough information to piece it together and solve your particular lookup-rename problem.
I created a utility method to help encapsulate how to rename a file.
public class FileUtilities
{
public static void RenameFile(string oldFilenameWithPathWithExtension, string newFilenameWithoutPathWithExtension)
{
try
{
string directoryPath = Path.GetDirectoryName(oldFilenameWithPathWithExtension);
if (directoryPath == null)
{
throw new Exception($"Directory not found in given path value:{oldFilenameWithPathWithExtension}");
}
var newFilenameWithPath = Path.Combine(directoryPath, newFilenameWithoutPathWithExtension);
FileInfo fileInfo = new FileInfo(oldFilenameWithPathWithExtension);
fileInfo.MoveTo(newFilenameWithPath);
}
catch (Exception e)
{
//Boiler plate exception handling
Console.WriteLine(e);
throw;
}
}
}
I omitted several other file system checks that could optionally be done, but as #JoelCoehoorn pointed out in a comment on this page, the File System is Volatile, so wrapping it in a try-catch may be all that is necessary.
With that class in your library, now you can simply call:
var fullFilename = #"C:\images\gallery\add.gif";
var newFilename = "Thumb.gif";
FileHelper.RenameFile(fullFilename,newFilename);
I have an XML file which is being uploaded to an ASP.Net page via the normal file upload control. When it gets up, I am attempting to validate and deserialize the XML. However, the code below is really very handy for validating an XML file which references it's XSD like this:
xsi:schemaLocation="someurl ..\localSchemaPath.xsd"
However, if I upload this XML file, only the XML file gets uploaded, so ..\localSchemaPath.xsd doesn't exist, so it can't validate.
Even if I stored the XSD locally, it still wouldn't be quite right as the XML file could be written with a schema location like:
xsi:schemaLocation="someurl ..\localSchemaPath.xsd"
or
xsi:schemaLocation="someurl localSchemaPath.xsd"
or
xsi:schemaLocation="someurl ..................\localSchemaPath.xsd"
if it so wished.
Dilemma!
(For the purposes of this question, I have pinched the code below from: Validating an XML against referenced XSD in C#)
using System.Xml;
using System.Xml.Schema;
using System.IO;
public class ValidXSD
{
public static void Main()
{
// Set the validation settings.
XmlReaderSettings settings = new XmlReaderSettings();
settings.ValidationType = ValidationType.Schema;
settings.ValidationFlags |= XmlSchemaValidationFlags.ProcessInlineSchema;
settings.ValidationFlags |= XmlSchemaValidationFlags.ProcessSchemaLocation;
settings.ValidationFlags |= XmlSchemaValidationFlags.ReportValidationWarnings;
settings.ValidationEventHandler += new ValidationEventHandler(ValidationCallBack);
// Create the XmlReader object.
XmlReader reader = XmlReader.Create("inlineSchema.xml", settings);
// Parse the file.
while (reader.Read()) ;
}
// Display any warnings or errors.
private static void ValidationCallBack(object sender, ValidationEventArgs args)
{
if (args.Severity == XmlSeverityType.Warning)
Console.WriteLine("\tWarning: Matching schema not found. No validation occurred." + args.Message);
else
Console.WriteLine("\tValidation error: " + args.Message);
}
}
Here is a chunk of code I use to validate xml with a local schema:
string errors = string.Empty;
try
{
XmlSchemaSet schemas = new XmlSchemaSet();
schemas.Add(string.Empty, Page.MapPath("~/xml/Schema.xsd"));
XmlDocument doc = new XmlDocument();
doc.Schemas = schemas;
doc.Load(Page.MapPath("~/xml/sampleXML.xml"));
//use this line instead of the one above for a string in memory.
//doc.InnerXml = xmlToValidate;
ValidationEventHandler validator = delegate(object send, ValidationEventArgs ve)
{
errors += "\n" + ve.Severity + ": " + ve.Message;
};
doc.Validate(validator);
}
catch (XmlException xe)
{
errors += "\n" + xe.Message;
}
catch (XmlSchemaValidationException xe)
{
errors += "\n" + xe.Message;
}
I can't quite make out whether you are attempting a generic validate-against-any-referenced-schema, or if you have a specific schema that you validate against every time, and are just not sure how to handle the references.
If it's the latter, then make the schema public on the internet, and tell people to reference it by URI.
If it's the former, then I would suggest the following:
First the user uploads an XML file.
Parse the XML file for a schema reference. Tell them "References to yourSchema.xsd were found; please upload this file below" with a new upload box.
Then, validate the file against the uploaded schema. To do this, modify the Schemas property of your settings object, instead of modifying the ValidationFlags property.
I want to populate
Response.ContentType = "text/plain";
From somewhere in the server/web/dictionary ALL possible MIME types according to file extension:
public string GetMimeType(string extension)
{
//This is what I am looking for.
}
Also, I have to rename the file (at least if going to be downloaded, so I have to know in advance if it's going to be opened or not.
You can store the mimetype when the file is uploaded ( FileUpload.PostedFile.ContentType ) and send that when the file is requested.
Umm... why? You're not going to be returning content of every possible type, are you?
Here's a list of common types: http://www.webmaster-toolkit.com/mime-types.shtml. There is no list that would include "ALL" types simply because any application vendor can create a custom one and associate it with a custom extension.
It's going to depend on your platform. Here's one for C# and IIS: http://blog.crowe.co.nz/archive/2006/06/02/647.aspx
In Powershell it's a one-liner:
([adsi]"IIS://localhost/MimeMap").MimeMap
The code in the link posted by Richard:
// Maintain a sorted list to contain the MIME Types
SortedList sl = new SortedList();
Console.WriteLine("IIS Mime Map - c#");
Console.WriteLine();
// Serve to connect to...
string ServerName = "LocalHost";
// Define the path to the metabase
string MetabasePath = "IIS://" + ServerName + "/MimeMap";
// Note: This could also be something like
// string MetabasePath = "IIS://" + ServerName + "/w3svc/1/root";
try
{
// Talk to the IIS Metabase to read the MimeMap Metabase key
DirectoryEntry MimeMap = new DirectoryEntry(MetabasePath);
// Get the Mime Types as a collection
PropertyValueCollection pvc = MimeMap.Properties["MimeMap"];
// Add each Mime Type so we can display it sorted later
foreach (object Value in pvc)
{
// Convert to an IISOle.MimeMap - Requires a connection to IISOle
// IISOle can be added to the references section in VS.NET by selecting
// Add Reference, selecting the COM Tab, and then finding the
// Active DS Namespace provider
IISOle.MimeMap mimetypeObj = (IISOle.MimeMap)Value;
// Add the mime extension and type to our sorted list.
sl.Add(mimetypeObj.Extension, mimetypeObj.MimeType);
}
// Render the sorted MIME entries
if (sl.Count == 0)
Console.WriteLine("No MimeMap entries are defined at {0}!", MetabasePath);
else
foreach (string Key in sl.Keys)
Console.WriteLine("{0} : {1}", Key.PadRight(20), sl[Key]);
}
catch (Exception ex)
{
if ("HRESULT 0x80005006" == ex.Message)
Console.WriteLine(" Property MimeMap does not exist at {0}", MetabasePath);
else
Console.WriteLine("An exception has occurred: \n{0}", ex.Message);
}
// Convert to an IISOle.MimeMap - Requires a connection to IISOle
// IISOle can be added to the references section in VS.NET by selecting
// Add Reference, selecting the COM Tab, and then finding the
// Active DS Namespace provider
According to my googling: (lost the links, sorry)
The "Active DS IIS Namespace Provider" is part of the IIS installation.
After you install IIS you will see that in the list of options.
If you don't see it should be located at C:\windows\system32\inetsrv\adsiss.dll.
To install IIS:
click Start, Settings, Control Panel, Add or Remove Programs, Add or Remove Windows Components, select Internet Informatoin Services (IIS).
Most of the code I've seen uses some combination of these:
using System.IO;
using System.DirectoryServices; // Right-click on References, and add it from .NET
using System.Reflection;
using System.Runtime.InteropServices;
using System.Collections;
using IISOle;
using System.Collections.Specialized;
The Active DS Namespace might be under the COM tab when adding the reference.
I've written a small class based on the webmaster-toolkit.com list. This is to avoid using COM and the IIS route or any IIS references.
It uses an XML serialized list which contains about 400 mimetypes, so is usually more than enough unless you have really obscure mimetypes. In that case you can just add to the XML file.
The full solution can be found here. Here's a sample:
class Program
{
static void Main(string[] args)
{
var list = MimeType.Load();
MimeType mimetype = list.FirstOrDefault(m => m.Extension == "jpg");
}
}
