CSPViolationReportBody: toJSON() method

None.

A JSON object that is the serialization of the CSPViolationReportBody object.

In this example we create a new ReportingObserver to observe CSP violation reports, then return a JSON representation of the first entry.

const observer = new ReportingObserver(
  (reports, observer) => {
    const firstReport = reports[0];
    // Log JSON object
    console.log(firstReport.toJSON());
    // Log JSON object as a string
    console.log(JSON.stringify(firstReport));
  },
  {
    types: ["csp-violation"],
    buffered: true,
  },
);

observer.observe();

We call toJSON() on the firstReport, which is a Report instance, which in turn results in the toJSON() defined in this interface being called to serialize the body of the report.

For the purpose of demonstration we also call JSON.stringify() on firstReport to create a string containing the JSON data. When sending or storing report information it is more common to do this than use toJSON() directly.
