网上有说是因为 cookie 没有传到服务器的问题 我在 swfupload 中加入了

post_params:{'session_id': '<%= cookies[:_session_id] %>','authenticity_token':'<%= form_authenticity_token.to_s %>'},

完整如下

$('#myModal #swfupload-control').swfupload({
                upload_url: "/ reply_messages/upload_ajax",
                post_params:{'session_id': '<%= cookies[:_session_id] %>','authenticity_token':'<%= form_authenticity_token.to_s %>'},

                file_post_name: 'uploadfile',
                file_size_limit : "2048",
                file_types : "*.jpg;*.bmp;*.jpeg;*.png;*.gif",
                file_types_description : "Image files",
                file_upload_limit : 5,
                flash_url : "/jquery-swfupload/js/swfupload/uploadify.swf",
                button_image_url : '/img/wdp_buttons_upload_114x29.png',
                button_width : 114,
                button_height : 29,
                button_placeholder : $('#myModal #button')[0],
                debug: false
            })

但还是相同问题 请问谁怎么要怎么改 知道的麻烦回复下感谢
