integrity 只读特性在 Request interface contains the subresource integrity value of the request.

句法

var myIntegrity = request.integrity;
					

值

subresource integrity value of the request (e.g., sha256-BpfBw7ivV8q2jLiT13fxDYAe2tJllusRSZ273h2nFSE= ).

If an integrity has not been specified, the property returns '' .

范例

In the following snippet, we create a new request using the Request.Request() constructor (for an image file in the same directory as the script), then save the request integrity value in a variable:

var myRequest = new Request('flowers.jpg');
var myIntegrity = myRequest.integrity;
