'温馨提示:
' 在flash的参数名upload_url中可自行定义一些参数(请求方式:POST),定义后在服务器端获取即可,比如可以应用到用户验证,文件的保存名等。
' 如下代码在上传接口Upload.asp中定义了一个user=xxx的参数:
' var swf = new fullAvatarEditor("swf", {
' id: "swf",
' upload_url: "Upload.asp?user=xxx"
' });
' 在本页即可用Upload.Form("user")获取xxx。
' 本示例未作极致的用户体验与严谨的安全设计(如用户直接访问此页时该如何,万一客户端数据不可信时验证文件的大小、类型等),只保证正常情况下无误,请阁下注意。
