Implementation Notes

Use GET:files/{fileid}/description to retrieve the file description.

C# Sample: Set File Description

The following code example sets the description of the file with ID 456:

Sample Code

Plug p = Plug.New("");
p.At("users", "authenticate").WithCredentials("admin", "password").Get();
DreamMessage msg = DreamMessage.Ok(MimeType.TEXT, "File description text");
p.At("files", "456", "description").Put(msg);

Sample Response from executing Code

<file id="456" href="">
    <description>File description text</description> 
    <contents type="image/pjpeg" size="53112" width="476" height="480" href="" /> 
    <contents.preview rel="thumb" type="image/pjpeg" maxwidth="160" maxheight="160" href="" /> 
    <contents.preview rel="webview" type="image/pjpeg" maxwidth="550" maxheight="550" href="" /> 
    <user.createdby id="1" href="">
    <revisions count="2" href="" /> 
    <page.parent id="29" href="">
        <title>DekiWiki (Hayes)</title> 
        <path /> 

Curl Sample: Set File Description

The following curl command will set or replace a description of a file according to its fileid (42, in the example). The description string is read out of file "description.txt".

Sample Code

curl -u username:password -T description.txt -i

Implementation notes 

curl flags

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


An image with image id 9 exists. We want to change its description to something generic, like "image 9". The file generic.txt contains the description we want to set.


Content-Type: text/plain

image 9

Sample Code

curl -u username:password -T generic.txt -i
