发送从弯曲对象的Java Servlet [英] Send objects from flex to java servlet

问题描述

这是我的动作方法

var urlVars : URLVariables = new URLVariables();
                urlVars.myname = byteArr;
                var urlReq : URLRequest = new URLRequest('MyServlet');
                urlReq.data = urlVars;
                urlReq.method = 'post';
                navigateToURL(urlReq, '_blank');

我如何接受她的字节数组的servlet？

How do I recieve the byte array on servlet ?

另外，byteArr以上来自Java端，

Also the byteArr above comes from java side,

byte[] byteArr = aMethodWhichReturnsaPDFByteArray();
        HttpServletResponse response = FlexContext.getHttpResponse();
        ServletOutputStream os = null;
        try {
            response.reset();
            response.setContentType("application/pdf");
            response.setContentLength(byteArr.length);
            response.setHeader("Content-disposition",
                    "inline; filename=\"Report.pdf\"");
            os = response.getOutputStream();
            os.write(byteArr);
            os.flush();
os.close();

以上方法没有奏效。

The above method did not work.

推荐答案

如果你坚持要送PARAMS这样，你在一个字符串再presentation最好的连接code中的字节数组。 <一href="http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/mx/utils/Base64En$c$cr.html?filter_flex=4.1&filter_flashplayer=10.1&filter_air=2"相对=nofollow> Base64的为例。在使用 commons- codeC 脱code它在Java端。

If you insist on sending the params this way, you'd better encode the byte array in a string representation. Base64 for example. On the java side used commons-codec to decode it.

否则，请参阅本文。这是一个有点老，但仍适用。此外看到这里

Otherwise, see this article. It's a bit old, but still applies. Also see here
