我的所有示例程序都遇到了类似的问题,其中包含来自WebApi的angularJS获取数据。我认为与我的代码无关,但有些设置可能会被忽略,请帮我检查一下: 这是我的网页api: 网址:http://localhost:1883/api/Subcriber 并返回数据:
Html正文:
<div id="tblSubs" ng-controller="APIController">
<table>
<tr>
<th>ID</th>
<th>Email ID ( Double click to update)</th>
<th>Subscribed Date</th>
<th></th>
</tr>
<tbody data-ng-repeat="sub in subscriber">
<tr>
<td>{{sub.SubscriberID}}</td>
<td ng-blur="updSubscriber(sub,$event)" ng-dblclick="makeEditable($event)">{{sub.MailID}}</td>
<td>{{sub.SubscribedDate}}</td>
<td>
<input type="button" id="Delete" value="Delete" data-ng-click="dltSubscriber(sub.SubscriberID)" />
</td>
</tr>
</tbody>
</table>
<div class="form-group">
<label for="email">Sbscribe here</label>
<input type="email" class="form-control" id="email" placeholder="Enter email" [required="string" ] data-ng-model="mailid" />
</div>
<button type="button" class="btn btn-default" data-ng-click="saveSubs();">Submit</button>
</div>
<script src="Scripts/angular.js"></script>
<script src="Scripts/angular-route.js"></script>
<script src="Scripts/ApiScripers/Module.js"></script>
<script src="Scripts/ApiScripers/Service.js"></script>
<script src="Scripts/ApiScripers/controller.js"></script>
AngularJS模块:
var app;
(function () {
app=angular.module('APIModule', []);
})();
AngularJS服务:
app.service("APIService", function ($http) {
this.getSubs = function () {
var url = 'api/Subscriber';
return $http.get(url).then(function (response) {
return response.data;
});
}
AngularJS控制器:
app.controller('APIController', function ($scope, APIService) {
getAll();
function getAll() {
var servCall = APIService.getSubs();
servCall.then(function (d) {
$scope.subscriber = d.data;
}, function (error) {
$log.error('Oops! Something went wrong while fetching the data.')
})
}
})
运行后,浏览器调试窗口中没有错误信息。这太奇怪了,我是否需要将我的webapi发布到IIS然后调用它?
更新 Index.cshtml:
@{
ViewBag.Title = "Welcome";
}
<style>
table, tr, td, th {
border: 1px solid #ccc;
padding: 10px;
margin: 10px;
}
</style>
<h2>Welcome to Sibeesh Passion's Email List</h2>
<body data-ng-app="APIModule">
<div id="tblSubs" ng-controller="APIController">
<table>
<tr>
<th>ID</th>
<th>Email ID ( Double click to update)</th>
<th>Subscribed Date</th>
<th></th>
</tr>
<tbody data-ng-repeat="sub in subscriber">
<tr>
<td>{{sub.SubscriberID}}</td>
<td ng-blur="updSubscriber(sub,$event)" ng-dblclick="makeEditable($event)">{{sub.MailID}}</td>
<td>{{sub.SubscribedDate}}</td>
<td>
<input type="button" id="Delete" value="Delete" data-ng-click="dltSubscriber(sub.SubscriberID)" />
</td>
</tr>
</tbody>
</table>
<div class="form-group">
<label for="email">Sbscribe here</label>
<input type="email" class="form-control" id="email" placeholder="Enter email" [required="string" ] data-ng-model="mailid" />

.cshtml可以从webapi获取数据,但我只是将html代码复制到我无法访问数据的.html文件中。希望有人可以帮助它。代码没有任何问题,可能是我忽略了一些包含。
答案 0 :(得分:0)
请务必抛出错误,以便在控制台窗口中看到它:
function getAll() {
var servCall = APIService.getSubs();
servCall.then(function (d) {
$scope.subscriber = d.data;
}, function (error) {
$log.error('Oops! Something went wrong while fetching the data.')
//THROW error
throw error;
})
}
当promise .then
方法拒绝处理程序省略throw
语句时,处理函数返回值undefined
。这将转换被拒绝的承诺到履行承诺。
$ Q:
由于e13eea,promise的onFulfilled或onRejection处理程序抛出的错误被视为与常规拒绝完全相同。以前,它也会被传递给$ exceptionHandler()(除了以错误为理由拒绝承诺)。
答案 1 :(得分:0)
它正在工作,我需要导入一些必要的库,例如jquery和bootstrap.js。但我发现了另一个问题: 起初,我认为我的代码不起作用,可能是我错了,从webapi获取数据的速度太迟了,所以我再也看不到了。仅仅2秒后,数据全部显示成功。 所以.cshtml文件的速度比.html文件快,是什么原因引起了这个问题。是否有人与我的问题相同。
