最近2天都在搞图片上传这个东西，真是有点麻烦。

在discuz 源码中看到一图片上传的好东西，刚好可以用到项目中来。于是决定尝试下把论坛中的图片上传独立出来

黄天不负有心人。就在刚才我把它搞出来了，而且通过了测试。

先将独立出来的部分发于博客中：

通过我的观察发现原来论坛中的flash上传图片是有三个部分组成。一是前台的js文件二是flash中的as文件三是asp.net中的代码处理

原理是这样的：

根据不同的浏览器js 加载flash文件和对于的参数【这个参数是页面传入的】到flash中处理文件【这是第一步的处理，只是将图片路径和用户信息传入到-->asp.net类中】这样asp。net类中就可以得到图片路径和用户信息，在得到用户信息以后，程序判断用户是否存在，是否有权限这样做。当后台验证通过了。就上传一个临时的图片文件到项目中并且return出去。 flash得到这个返回值判断临时图片是否上传成功了，如果成功，将图片显示出来并且可以用于截图使用，这样可以截取的图片就出来了。下面的操作就是用户选择大小选择截图的位置。点击确定。这个时候flash就第二次访问asp。net中的类【这是第二次的处理，将临时文件delete将用户截取的图片上传到正式的图片中去】当asp。net中的类处理操作完成了return true。这样页面上传图片就算是成功了。

原理我明白以后下面要做的就是将这些我需要的文件搞出来，不要的果断就抛下了

前台的js 我的项目中就可以直接的使用静态的了

写法是：

注意：ucapi=http://192.168.0.101/ajaxpage.aspx\" 这是一个参数用处是：flash和哪一个asp.net的类联系。这个参数必不可少，而且必须用绝对路径，不然是要报错的。

通过上面的方法如果js没错的话应该在页面上看到：这样的效果。

下一步就对ajaxpage页面做修改。

原来的页面情况是：在flash中指定的是ajax.aspx页面而ajax页面中将处理的内容是放到一个类中的，当然我们完全可以不用它这种方式直接新建一个页面--》ajaxPage页面就行了。

页面代码和药修改的地方：

可以看到这个类少了很多以前的东西，以为我们不必要处理那么多的事件，只是一个单纯的上传图片的处理而已。

主要要修改的地方：是上传图片的路径【一个是临时文件，第二个是保持的文件路径】。
