問題解決了，iframe設(shè)置允許就可以了

To continue to use permissions from iframes on your website...
This deprecation is expected to ship in Chrome M64 (around January 2018). At that time, if a cross-origin iframe attempts to use permission without the feature being explicitly allowed, a console warning will be logged and the feature will fail in a similar way as it would if a user had denied a permission prompt.

If you are a developer of a website which uses cross-origin iframes and you want those iframes to continue to be able to request/use one of the above features, the page that embeds the iframe will need to be changed. The simplest way to do that is to modify the <iframe> tag to include an allow attribute which specifies the name of the permission. For example, to enable geolocation and mic/camera for an iframe, the following would be specified:

<iframe src="https://example.com" allow="geolocation; microphone; camera"></iframe>

Valid values for allow include:
geolocation
microphone
camera
midi
encrypted-media
Note that if the iframe which is using the permission has the same origin as the top level page, then no changes have to be made.
