Question

我正在尝试更新客户反馈帖子，POST＆amp;删除工作，但我已经被困在PUT上几天了。任何帮助都会很棒。感谢

厂

app.factory('Post', function ($resource) {

return $resource('/api/apiPost/:id',
{ id: '@id' },
{ 'save': { method: 'POST' } },
{ 'update': { method: 'PUT' } },
{ 'query': { method: 'GET', isArray: false } });

}）;

CONTROLLER

$scope.updatePost = function (post) {
    //alert("WORKS");
    Post.update({ id: post.PostId }, $scope.post, function () {
        $scope.postArray.push(post);
        $scope.post = {
            Title: '',
            Body: ''
        };
    }, function () { });


}

ADAPTER

 public Post PutNewPost(int id, Post newPost)
    {

        Post post = new Post();
        post.PostId = newPost.PostId;
        post.Title = newPost.Title;
        post.Body = newPost.Body;
        post.Hidden = newPost.Hidden;

        db.Posts.Add(post);
        db.SaveChanges();

        return db.Posts.FirstOrDefault();
    }

API CONTROLLER

// PUT api/<controller>/5
    [Authorize(Roles = "Admin")]
    public IHttpActionResult Put(int id, [FromBody]Post newPost)
    {
        if (!ModelState.IsValid)
        {
            return BadRequest(ModelState);
        }

        return Ok(_adapter.PutNewPost(id, newPost));
    }

我认为$ resource的方法参数是错误的。将所有自定义方法返回到1个对象中，如下所示：

app.factory('Post', function ($resource) {

return $resource('/api/apiPost/:id',
    { id: '@id' },
    { 
        'save': { method: 'POST' },
        'update': { method: 'PUT' },
        'query': { method: 'GET', isArray: false }
    }
);

为什么PUT不被控制器识别？
