referrerPolicy
特性为
HTMLScriptElement
interface reflects the HTML
referrerpolicy
的
<script>
element and fetches made by that script, defining which referrer is sent when fetching the resource.
refStr = scriptElem.referrerPolicy; scriptElem.referrerPolicy = refStr;
A
DOMString
; one of the following:
Referer
header will be omitted entirely. No referrer information is sent along with requests.
This is the user agent's default behavior if no policy is specified. The URL is sent as a referrer when the protocol security level stays the same (e.g.HTTP→HTTP, HTTPS→HTTPS), but isn't sent to a less secure destination (e.g. HTTPS→HTTP).
https://example.com/page.html
will send the referrer
https://example.com/
.
Send a full URL when performing a same-origin request, but only send the origin of the document for other cases.
Only send the origin of the document as the referrer when the protocol security level stays the same (e.g. HTTPS→HTTPS), but don't send it to a less secure destination (e.g. HTTPS→HTTP).
Send a full URL when performing a same-origin request, only send the origin when the protocol security level stays the same (e.g. HTTPS→HTTPS), and send no header to a less secure destination (e.g. HTTPS→HTTP).
Send a full URL when performing a same-origin or cross-origin request. This policy will leak origins and paths from TLS-protected resources to insecure origins. Carefully consider the impact of this setting.
注意
: An empty string value (
""
) is both the default value, and a fallback value if
referrerpolicy
is not supported. If
referrerpolicy
is not explicitly specified on the
<script>
element, it will adopt a higher-level referrer policy, i.e. one set on the whole document or domain. If a higher-level policy is not available, the empty string is treated as being equivalent to
no-referrer-when-downgrade
.
var scriptElem = document.createElement("script");
scriptElem.src = "/";
scriptElem.referrerPolicy = "unsafe-url";
document.body.appendChild(script);
