Implementation Notes

A single Expert site can store up to 5,000 attachments.

File uploads to template pages are not allowed. 

If a file with the same name already exists on the specified page, a new revision of the existing file is uploaded.  Otherwise, a new file is created.

The contents.preview element only exists if a file preview is available.  Preview generation requires the file to be an image and fall within a certain size.

C# Sample: Upload a file to a page

The following code example uploads the file "myfile.jpg" to the home page:

Plug p = Plug.New("http://help.mindtouch.us/@api/deki");
p.At("users", "authenticate").WithCredentials("admin", "password").Get();
DreamMessage msg = DreamMessage.FromFile("c:\\temp\\myfile.jpg");
msg = p.At("pages", "home", "files", "=myfile%252ejpg").With("description", "File description text").Put(msg);

Sample response indicating that the second revision of "myfile.jpg" was successfully uploaded:

<file id="456" revision="2" href="http://help.mindtouch.us/@api/deki/files/456/info?revision=2">
    <filename>myfile.jpg</filename>
    <description>File description text</description>
    <contents type="image/jpeg" size="53112" width="476" height="480" href="http://help.mindtouch.us/@api/deki/files/456?revision=2" />
    <contents.preview rel="thumb" type="image/jpeg" maxwidth="160" maxheight="160" href="http://help.mindtouch.us/@api/deki/files/456?revision=2&amp;size=thumb" revision="2" />
    <contents.preview rel="webview" type="image/jpeg" maxwidth="550" maxheight="550" href="http://help.mindtouch.us/@api/deki/files/456?revision=2&amp;size=webview" revision="2" />
    <date.created>2007-09-06T19:23:21Z</date.created>
    <user.createdby id="1" href="http://help.mindtouch.us/@api/deki/users/1">
        <nick>Admin</nick>
        <username>Admin</username>
        <email>admin@mindtouch.com</email>
    </user.createdby>
    <page.parent id="29" href="http://help.mindtouch.us/@api/deki/pages/29">
        <title>DekiWiki (Hayes)</title>
        <path></path>
    </page.parent>
</file>

Curl Sample: Upload an image to a page

The following curl command issues a PUT request to send file "foo.jpg" and upload it to page "test" under the name "bar.jpg".

Sample Code

curl -u username:password -T foo.jpg -i http://mindtouch.address/@api/deki/pages/=test/files/=bar.jpg

Implementation notes 

curl flags

-u
Basic HTTP authentication. Sends a username and password to server so it can verify whether a user is of privilege to perform specific operation.
-T
Sends a file using the PUT command.
-i
Includes the HTTP response header in the output. Useful for debugging.

 

Example

The following curl command will attach the (legal) image "patrickstewart.jpg" to Jean Luc Picard's page under the name "captain.jpg".

patrickstewart.jpg

patrickstewart.jpg

Sample Code

curl -u username:password -T patrickstewart.jpg -i http://192.168.168.110/@api/deki/pages/=Jean%2520Luc%2520Picard/files/=captain.jpg

Notes

  • The page path is double encoded. In the above example, spaces in "Jean Luc Picard" are replaced with %2520.
  • Running the command again with the same path will overwrite the stored image.
