aardio 范例：上传文件

//上传文件
import win.ui;
/*DSG{{*/
var winform = win.form(text="web form 上传文件";right=717;bottom=524;parent=...;scroll=1)
winform.add()
/*}}*/

import web.form;
var wb = web.form( winform );//创建web窗体
string.save("/test.txt","这是测试数据" );//构建数据包

//构建上传数据包
import web.multipartFormData;
var formData = web.multipartFormData();
formData.add("username","用户名");
formData.add("password","密码");
formData.add("file1","@/test.txt") 

//httpbin.org总是会返回JSON,用FileDownload事件取消JSON下载
wb.FileDownload = function( activeDocument, cancel) {if( !activeDocument ) return true;} 
wb.post("http://eu.httpbin.org/post"
    , formData.readAll() //上传数据包 
    , formData.contentHeader()  //要添加的HTTP头
    );
winform.show() 

//也可以用inet.http上传(与web.form共享会话)
import inet.http;
import string.html;
var http = inet.http(wb.script.navigator.userAgent);
var json = http.post("http://eu.httpbin.org/post" 
    , formData.readAll() //上传数据包 
    , formData.contentHeader()  //要添加的HTTP头
    );
wb.write(string.html.fromText(json));

//启动消息循环
win.loopMessage();
