userdata userdata

User data from image catalog. Returns user data for the image catalog entry specified in the url path.

req=userdata[,text|{xml[, *encoding*]}|json]

UTF-8 | UTF-16 | UTF-16LE | UTF-16BE | ISO-8859-1

The contents of catalog::UserData are returned. When ‘text’ format is specified, all instances of ?? in catalog::UserDataare replaced by line terminators, and a single-line terminator (CR/LF) is appended to the end. If the URL path does not resolve to a valid catalog entry, the response consists only of a single-line terminator. Appropriate formatting is applied when ‘xml’ or ‘json’ format is requested.

Other commands in the request string are ignored.

The HTTP response is cacheable with the TTL based on catalog::Expiration.

The colon character is not allowed in userdata property key names.

Requests that support JSONP response format lets you specify the name of the JS callback handler using the extended syntax of req= parameter:

req=...,json [&handler = reqHandler ]

<reqHandler> is the name of the JS handler that is present in the JSONP response. Only a-z, A-Z, and 0-9 characters are allowed. Optional. Default is s7jsonResponse.
