Proposed Changes

• This code change allows users to pass down simple Strings to query for Content Analytics data.
• Considering the formatting of different values, a special notation must be used to specify certain parameters in the URL path.
• You can do a POST REST call using a JSON body like this one:

{
    "measures": "request.count request.totalSessions",
    "dimensions": "request.host request.whatAmI request.url",
    "timeDimensions": "request.createdAt:day:Last month",
    "filters": "request.totalRequest gt 0:request.whatAmI contains PAGE,FILE",
    "order": "request.count asc:request.createdAt asc",
    "limit": 5,
    "offset": 0
}

The following must be taken into account when putting a query together:

• Measures: Values are separated by blank spaces: request.count request.totalSessions
• Dimensions: Values are separated by blank spaces: request.host request.whatAmI request.url
• Time Dimensions: Values are separated by colons: request.createdAt:day:This month . The second parameter 'day' -- the "granularity" parameter -- is optional.
• Filters: Values are separated by colons: request.totalRequest gt 0:request.whatAmI contains PAGE,FILE . In this case, you're filtering by the number of requests, and the type of object being queried: Pages and Files.
• Order: Values are separated by colon: request.count asc:request.createdAt asc
• Limit: Value is provided as is: 50
• Offset: Value is provided as is: 0
