Javascript AngularJS承诺返回时出错，但成功地将内容发送到db

使用

error.status

在控制台日志中获得的错误为

-1

，但我发送到数据库的数据已成功发布。数据显示在我的

ng repeat

列表中。这很奇怪，因为有5%的时候会发生

这是我的控制器：

    angular.module('app')
.controller('WebsiteCtrl', ['WebsiteService', '$scope', '$http', '$timeout', '$uibModal', function (WebsiteService, $scope, $http, $timeout, $uibModal, $uibModalInstance) {

我的服务：

    //Website Service class that executes the CRUD functionality
angular.module('app').factory('WebsiteService', ['$http', '$q', function ($http, $q) {

    var factory = {

    function deleteWebsite(id) {
        var deferred = $q.defer();
        console.log('Service: ', id);

            .then(
            function (response) {
                deferred.resolve(response.data);

        //returns a promise that function was successful or failed
        //helps control async calls
        return deferred.promise;
    };

}]);

它发生在所有与数据库相关的函数上，但我正在使用addWebsite函数获取有用的数据。当这种情况很少发生时，很难进行调试

任何帮助都将不胜感激！提前谢谢

编辑 下面是一张将错误设置为-1并显示“网络”选项卡的图片。这在不同的选项卡中，但代码相同。

---

根据angularjs文件：“介于200和299之间的响应状态代码被视为成功状态，并将导致调用成功回调。超出该范围的任何响应状态代码都被视为错误状态，并将导致调用错误回调。此外，小于-1的状态代码被标准化为零-1通常表示请求被中止，例如使用config.timeout。注意，如果响应是重定向，XMLHttpRequest将透明地跟随它，这意味着结果（成功或错误）将由最终响应状态代码决定。“请看：$http。

在我看来，问题一定出在您的api中。您可能无法从API201中获取数据，这是可能的，因为我正在Microsoft的实体框架中抛出json数据块。但是有没有什么可以确定的呢？我完全不知所措，因为我向用户显示成功和错误消息，而显示一次性错误并不专业！：（调试API或（如果适用）阅读API的日志。您可以通过查看浏览器控制台中的“网络”选项卡来确定是否有任何错误。您应该能够在chrome developer控制台中看到您请求的状态代码。更新帖子以显示错误发生的图片。同时显示网络控制台。如果错误为-1，那么我可以忽略错误吗？例如在错误函数中添加if语句，检查它是否为-1。最好不要忽略。检查它是否启动重复请求（第一个请求成功完成，第二个请求被拒绝或超时）。请尝试对您的请求使用其他超时值。也请查看您的Web服务的超时。据我所知，我没有重复的请求。我能想到的唯一原因是请求的速度。如果它触发得太快。事实上，查看有关请求的照片，似乎在超时时间结束之前它已被取消不是吗？请查看请求的“暂停”状态，并将其与超时进行比较。无论如何，请尝试增加超时，因为webservice操作涉及访问数据库等昂贵的操作。谢谢，我将对此进行研究。这在很大程度上解决了我的问题，因为我现在知道angular的状态代码。谢谢艾恩！
