swfupload上传控件的使用

1、关于图片上传控件，flash控件的显示效果要好一些，本人使用swfupload

2、swfupload上传控件使用方式详见文档 http://www.leeon.me/upload/other/swfupload.html

3、参照文档说明和官方demo，写一个小例子是没有任何问题的，在firefox或者chrome下如碰到302错误，错误堆栈如下

看到红色文字302部分是不是很熟悉？我简单说明下为什么会出现这个问题

a 、flash上传图片时，会另起一个线程上传，这个线程中没有cookie，session等会话信息，包括自定义的全局变量，调用上传的url路径后台进行处理时，如果后台进行了权限或者登陆校验就会校验失败，后台校验失败就会重定向登录页面，flash这边就会报出302错误，但是上传界面不会发生跳转。

b、如果程序使用了系统框架，一般框架会有过滤器进行权限校验或者session校验，对于框架不熟悉的人可能不知道为什么发生302错误，也不知道在哪处理过滤，导致无法解决问题，这个需要仔细研究框架了。

c、对于swfupload的demo可以直接部署运行，而不报错，就是因为接收图片界面没有校验session或者权限

没有什么登录，我就改了个文件名随机，保存路径就出错了。。。

robbins2009 写道

问题时我不需要这些验证，但是取不到当前登录人啊

那就让系统开放一个不需要权限验证的接口出来专门做上传使用，应该是可以做到的

和你碰到一样的问题了，也是权限框架过滤了请求，直接重定向到uc
