Using the common report collector

To send reports to the collector, configure the reporting API to POST reports to the collector's URL. This can be same- or cross- origin with the reporting document, as the collector will follow the CORS protocol.

The collector supports both CSP Level 2 (report-uri) reports as well as Reporting API reports.

A GET request can be used to retrieve stored reports for analysis.

A POST request can be used to clear reports stored in the server.

Sent credentials are stored with the reports, and can be retrieved separately.

CORS Notes:

• Preflight requests originating from www2.web-platform.test will be rejected. This allows tests to ensure that cross-origin report uploads are not sent when the endpoint does not support CORS.

Supported GET parameters:

op: For GET requests, a string indicating the operation to perform (see below for description of supported operations). Defaults to retrieve_report.

reportID: A UUID to associate with the reports sent from this document. This can be used to distinguish between reports from multiple documents, and to provide multiple distinct endpoints for a single document. Either reportID or endpoint must be provided.

endpoint: A string which will be used to generate a UUID to be used as the reportID. Either reportID or endpoint must be provided.

timeout: The amount of time to wait, in seconds, before responding. Defaults to 0.5s.

min_count: The minimum number of reports to return with the retrieve_report operation. If there have been fewer than this many reports received, then an empty report list will be returned instead.

retain: If present, reports will remain in the stash after being retrieved. By default, reports are cleared once retrieved.

Operations:

retrieve_report: Returns all reports received so far for this reportID, as a JSON-formatted list. If no reports have been received, an empty list will be returned.

retrieve_cookies: Returns the cookies sent with the most recent reports for this reportID, as a JSON-formatted object.

retrieve_count: Returns the number of POST requests for reports with this reportID so far.

Supported POST JSON payload:

op: For POST requests, a string indicating the operation to perform (see below for description of supported operations).

reportIDs: A list of reportIDs, each one a UUID associated with reports stored in the server stash.

Operations

DELETE: Clear all reports associated with reportID listed in reportIDs list.

Example usage:

# Clear reports on the server.
fetch('/reporting/resources/report.py', {
  method: "POST",
  body: JSON.stringify({
    op: "DELETE",
    reportIDs: [...] # a list of reportID
  })
});
