ajax帖子中的错误：405

Question

我构建了允许更新和上传帖子的应用程序。我通过ajax进行更新后，但出于某种原因，我收到“POST 405（方法不允许）”的错误。

我做了类似的代码来写一篇新帖子，它运行正常。您认为这是什么问题？

以下是代码：

  $("form#updata_post").submit(function(event){

    event.preventDefault();


    tinyMCE.triggerSave();

 text_body = $("#body").val();

$("#all_body").val(text_body);





      var formData = new FormData($(this)[0]);

    $.ajax({
        url: "{{Request::root(); }}/updata_post/",
        dataType: "json",
        type: "POST",
        data: formData,
       success: function(data) { 

           $(".info").hide().find("ul").empty(); 


         if (!data.success) {


          $.each(data.errors, function(index, error){

             $(".info").append("<ul>" + error + "</ul>"); 

          });

          $(".info").slideDown( "slow" );




    }

       else {

      window.location = "{{URL::to('posts')}}";



       }


      }, 

        cache: false,
        contentType: false,
        processData: false
    });

});

public function updata_post() {
   $validator = Validator::make(Input::all(), postmodel::$rules);
    if ($validator->passes()) {

   $id = Input::get('id');
    $post =  postmodel::find($id);
          $img_file = Input::file('file');
       if (!empty($img_file)) {
   $image = Input::file('file');
   $imagename = rand(1,99999).$image->getClientOriginalName();
    $upload = $image->move(public_path() . "/img/",$imagename);
    $post->main_img = $imagename;
    }

   $post->description = Input::get('description');

   $post->title = Input::get('title');
   $post->all_files = Input::get('all_files');
   $slug = Input::get('slug');
   if (!empty($slug)) {
    $post->slug = str_replace(" ", "-", Input::get('slug'));
   }
   else {
    $post->slug = str_replace(" ", "-", Input::get('title'));
   }
   $post->body = Input::get('text_body');
   $post->name = Input::get('name');
   $post->section = Input::get('section');

   $post->save();
   //return Redirect::to('posts');
   return Response::json(['success' => true]);
  }
    else {
   return Response::json(['success' => false, 'errors' => $validator->messages()->toArray()]);

}
