matchAll() 方法在 缓存 interface returns a Promise that resolves to an array of all matching responses in the 缓存 对象。

句法

cache.matchAll(request, {options}).then(function(response) {
  // do something with the response array
});

参数

request 可选


									Request

for which you are attempting to find responses in the


									缓存

. This can be a


								Request

object or a URL. If this argument is omitted, you will get a copy of all responses in this cache.

选项可选

An options object allowing you to set specific control options for the matching performed. The available options are:

ignoreSearch : A 布尔 that specifies whether the matching process should ignore the query string in the url. If set to true ， ?value=bar 部分在 http://foo.com/?value=bar would be ignored when performing a match. It defaults to false .
ignoreMethod : A 布尔 that, when set to true , prevents matching operations from validating the Request http method (normally only GET and HEAD are allowed.) It defaults to false .
ignoreVary : A 布尔 that when set to true tells the matching operation not to perform VARY header matching — i.e. if the URL matches you will get a match regardless of the 响应 object having a VARY header or not. It defaults to false .

返回值

A Promise that resolves to an array of all matching responses in the 缓存 对象。

注意 : Cache.match() is basically identical to Cache.matchAll() , except that rather than resolving with an array of all matching responses, it resolves with the first matching response only (that is, response [0] ).

范例

caches.open('v1').then(function(cache) {
  cache.matchAll('/images/').then(function(response) {
    response.forEach(function(element, index, array) {
      cache.delete(element);
    });
  });
})
