Question

首先，我有这样的工厂：

app.factory('getApiUrl', function (httpq, $q) {

    var obj = {};
    obj.getResponse = function (hurl) {
        var promise = $q.defer();

        httpq.get(hurl).then(function (data) {
            //obj = data.data;
            promise.resolve(data.data);
        })

        return promise.promise;

    }
    return obj;
});

然后我创建控制器并像这样调用工厂：

app.controller('mainController', function ($scope, httpq, $q, getApiUrl) {
    $scope.message = "Main Content";
    var namees = new Array();
    var testc = getApiUrl.getResponse(hurl);
    $scope.names = testc.data;
});

但它没有用。

getResponse方法返回promise object。您需要为响应何时解决提供回调。那么正确的用法是：

app.controller('mainController', function ($scope, httpq, $q, getApiUrl) {
    $scope.message = "Main Content";
    var namees = new Array();
    getApiUrl.getResponse(hurl).then(function(data) {
        var testc = data;
        $scope.names = testc.data;
    });
});

作为旁注，您还应该摆脱服务中的多余$q.defer，因为httpq.get(hurl)已经是一个承诺：

obj.getResponse = function (hurl) {
    return httpq.get(hurl).then(function (data) {
        return data.data;
    });
}
