The report JSON object has a single top-level property, "csp-report", which contains an object with the following properties
blocked-uri : The URI of the resource that was blocked from loading by the Content Security Policy. If the blocked URI is from a different origin than the document-uri, then the blocked URI is truncated to contain just the scheme, host, and port. disposition : Either "enforce" or "report" depending on whether the {{HTTPHeader("Content-Security-Policy-Report-Only")}} header or the Content-Security-Policy header is used. document-uri : The URI of the document in which the violation occurred. effective-directive : The directive whose enforcement caused the violation. Some browsers may provide different values, such as Chrome providing style-src-elem/style-src-attr, even when the enforced directive was style-src. original-policy : The original policy as specified by the Content-Security-Policy HTTP header. referrer {{Deprecated_Inline}} {{Non-standard_Inline}} : The referrer of the document in which the violation occurred. script-sample : The first 40 characters of the inline script, event handler, or style that caused the violation. Violations originating from external files are not included in the report.
status-code : The HTTP status code of the resource on which the global object was instantiated. violated-directive {{deprecated_inline}} : The directive whose enforcement caused the violation. The violated-directive is a historic name for the effective-directive field and contains the same value.
