Question

我正在向WordPress帐户发出$http.jsonp个请求，我的状态为304，看起来像这样

posts?callback=angular.callbacks._0 GET 304，

这是我在浏览器的网络部分看到的内容

这是我需要的确切对象，请参阅服务和控制器中的请求

.service('FreshlyPressed', function($http, $q) {
  return {

    getBlogs: function($scope) {
      var posts = [];
      $http.jsonp('http://urbanetradio.com/wp-json/posts?callback=JSON_CALLBACK')
        .success(function(result) {
          console.log(result);
          $scope.posts = result;
        })
    }
});

.controller('NewsCtrl', function($scope, FreshlyPressed) {

  $scope.doRefresh = function() {
    $scope.posts = FreshlyPressed.getBlogs($scope);
    $scope.$broadcast('scroll.refreshComplete');
  };
  $scope.doRefresh();
});

和html

<div ng-repeat="post in posts">
  <a ng-href="#/tabs/news/{{post.ID}}">
    <h2 ng-bind-html="post.title"></h2>
    <p>{{:: post.date | date}}</p>
  </a>
</div>

我正在用jsonp这样做，因为Access-Allow-Control-Origin。

Here is a Plunker以防你想看一看。

问题在于，如果您使用简单的$http.get，您可以在视图中看到呈现的帖子，但只能在浏览器中的本地环境中看到，但是一旦您尝试在移动设备中运行该应用，然后出现这个错误

XMLHttpRequest无法加载http://urbanetradio.com/wp-json/posts。请求的资源上不存在“Access-Control-Allow-Origin”标头。因此，不允许原点“http://localhost:8100”访问。

添加$http.jsonp会使请求变得清晰，错误不再存在，但您无法在DOM中看到数据。

修改

现在，根据我的问题，我只是在插件的Changelog视图中看到了一个文本

Add handling for Cross-Origin Resource Sharing (CORS) OPTIONS requests. Preflighted requests (using the OPTIONS method) include the headers Access-Control-Allow-Origin, Access-Control-Allow-Methods, and Access-Control-Allow-Credentials in the response, if the HTTP origin is set.

以防万一，this is the plugin I am using, WP REST API

这是什么意思？

无法将jsonp请求的内容放在视图
