jquery - Spring 3 jquery ajax删除

Question

我正在尝试使用 jquery 进行 ajax 删除，但收到 http 错误 400。我正在搜索，发现jquery中的delete方法存在一些问题。

这是我的 js、 Controller (spring 3) 和来自 Chrome 的请求。

如果您现在有什么错误，请告诉我，或提供一些链接。

$.ajax({  
                url: 'additions/cancelUpload',  
                type: 'DELETE',  
                data: {filename : ui.draggable.get(0).file.name},  
                success: function (res) {  
                    alert(res);
                }  
            }); 

这里执行没有通过:

@RequestMapping(value = "cancelUpload", produces="text/html")
    @ResponseBody
    public String cancelUpload(@RequestParam("filename")String filename, HttpSession session ){ 
... 
} 

请求:

我设法收到删除请求

 @RequestMapping(value = "cancelUpload", produces="text/html" method = RequestMethod.DELETE)

但是这样做

$.ajax({  
            url: 'additions/cancelUpload',  
            type: 'POST',  
            data: {filename : ui.draggable.get(0).file.name, _method: 'DELETE'},  
            success: function (res) {  
                alert(res);
            }  
        }); 

您可以在 http://blog.springsource.org/2009/03/08/rest-in-spring-3-mvc/ 中阅读有关 _method: 'DELETE' 参数的 post 请求

如果有人现在如何发送真正删除 AJAX 请求。请告诉我
