[英]How to access params to get a single object in $resource?
So I am trying to get a single "post" object from a list of posts but i don't know the name of passed params object name. 因此,我试图从帖子列表中获取单个“ post”对象,但我不知道传递的params对象名称的名称。 Here's post-details component 'use strict';
这是细节后的组件“严格使用”;
angular.module('postDetail', ['ngRoute', 'postsService'])
.config(['$routeProvider', function($routeProvider) {
$routeProvider.when('/posts/:postId', {
templateUrl: 'post-detail/post-detail.template.html',
controller: 'PostDetailController'
});
}])
.controller('PostDetailController', ['$scope', '$http', 'postsService', '$routeParams', function($scope, $http, postsService, $routeParams) {
$scope.post = postsService.getPost($routeParams.postId);
}]);
Here I am passing postId to the getPost method. 在这里,我将postId传递给getPost方法。 BTW, here the value of postId is valid.
顺便说一句,这里的postId的值是有效的。
This is my Posts Service. 这是我的邮政服务。
angular.
module('postsService', ['ngResource']).
factory('postsService', ['$resource',
function($resource) {
return $resource('https://jsonplaceholder.typicode.com/posts/:postId', {}, {
getPost: {
method: 'GET',
params: {postId: '@postId'}
}
});
}
]);
But here the "@postId" expression is empty and it tries to get the list of posts. 但是这里的“ @postId”表达式为空,它试图获取帖子列表。 How can i reference the passed parameter?
如何引用传递的参数?
My post details template 我的帖子详细信息模板
<h3>{{post.title}}</h3>
<p>{{post.body}}</p>
Instead of: 代替:
$scope.post = postsService.getPost($routeParams.postId);
do: 做:
$scope.post = postsService.getPost({
postId: $routeParams.postId
});
Check out the example of how to use $resource
class methods in the documentation . 在文档中查看如何使用
