External User Consent Flow
Introduction
Sometimes publishers want to collect user consent using external prompt UI flow with iframes. This sample demonstrates how you can use amp-consent
together with amp-iframe
to achieve this. In this sample we'll build a consent dialog from an iframe.
Setup
We need to import both, the amp-consent
...
<script async custom-element="amp-consent" src="https://cdn.ampproject.org/v0/amp-consent-0.1.js"></script>
... and the amp-iframe
extension.
<script async custom-element="amp-iframe" src="https://cdn.ampproject.org/v0/amp-iframe-0.1.js"></script>
Defining the Consent Flow
We define a basic consent flow, similar to this sample. The consent dialog is from a CORS iframe loaded with the amp-iframe
component
<amp-consent id="myUserConsent" layout="nodisplay">
<script type="application/json">{
"consentInstanceId": "iframe-consent",
"checkConsent": "remote",
"checkConsentHref": "/documentation/examples/api/get-consent",
"promptUI": "myConsentFlow",
"postPromptUI": "post-consent-ui"
}</script>
<div id="myConsentFlow" class="popupOverlay">
<div class="consentPopup">
<amp-iframe layout="fill" sandbox="allow-scripts allow-same-origin allow-popups allow-popups-to-escape-sandbox" src="/static/samples/files/external-consent-iframe.html">
<div placeholder>Loading</div>
</amp-iframe>
</div>
</div>
<div id="post-consent-ui">
<button on="tap:myUserConsent.prompt()">Update Consent</button>
</div>
</amp-consent>
Consent Dialog Iframe
The consent dialog iframe can inform the amp-consent
component user's choice through postMessages.
window.parent.postMessage({ type: 'consent-response', action: 'accept' }, '*');
Here action can be either 'accept'
, 'reject'
or 'dismiss'
.
Use data-block-on-consent
attribute to block AMP components until consent is given.
Individual AMP components can override blocking behavior and implement blocking logic themselves.
Here is an image which is blocked until consent is given:
<amp-img data-block-on-consent src="/static/samples/img/landscape_lake_300x201.jpg" width="300" height="201">
</amp-img>
إذا لم تكن الإيضاحات الموجودة في هذه الصفحة تُجيب على جميع أسئلتك، فلا تتردد في التواصل مع مستخدمي AMP الآخرين لمناقشة حالة الاستخدام المحددة لديك بالضبط.
