javascript - Angular Promise Promise Decorator 得到 Resolve

Question

我试图在 promise 解析完成时收到消息

$provide.decorator('$q', function ($delegate) {
    var defer = $delegate.defer;
    $delegate.defer = function () {
        var deferred = defer();
        console.log("defer");
        return deferred;
    };
    $delegate.resolve = function () {
        var resolved = resolve();
        console.log("resolve");
        return deferred;
    };
    return $delegate;
});

我不确定这是否完全正确，但想象一下，它看起来像这样

$provide.decorator('$q', function ($delegate) {
    var defer = $delegate.defer;
    $delegate.defer = function () {
        var deferred = defer(),
            resolve = deferred.resolve;

        deferred.resolve = function(data) {
            console.log('resolved');
            return resolve(data);
        };

        return deferred;
    };
    return $delegate;
});
