我去，看这个还不如去找几个java批量上传的例子 利用swfupload实现java文件批量上传

[心随自在飞]

看标题还说你走错门了嘞 找PHP 大神怎么来Java板块了、

[tony4geek]

你需要会php又会java的。

[_南天北落]

@执笔记忆的空白 版主能不能给我2015 12版的花。

[_南天北落]

你可以去找java上传的demo。这样多简单。何必费劲去转呢。

这个是按你每个月的专家分排名的

大神，你可以帮我把java转php么，， 这是java的一段代码，求转换 Map<String, String> params = new HashMap<String, String>(); //这是一个java李的map。。。 params.put("returnUrl","xxxxxxxxxx"); //md5加密 params.put("sign", Snippet.encode(params.get("id")+params.get("appid")+params.get("orderidinf")+params.get("totalPrice")+KEY)); //格式化成key=val&key=val&的样子（你可以省略这个，，） String data=Snippet.createLinkString1(params); String result=null; //发送https请求，获取到参数 result=Snippet.httpsSendMessage(data, URL + "service/api/controller/zitopay/topayByMc"); //转换成json，，c#我不知道叫啥，，随便搞个把 JSONObject json = JSONObject.fromObject(result); //获取到值 String signString = ID + APPID + json.get("orderidinf") + json.get("totalPrice")+KEY; //做一个验签 if (Snippet.md5check((String) json.get("sign"), signString)) { System.out.println("验签成功"); }
