Question

当我在servlet 1中调用servlet 2的URL时

URLConnection urlConnection = someURL.openConnection();

响应是XML文件附件，Content-Disposition: attachment； filename=xxxx Content-Type:XML

现在我想解析附件XML文件，我试过BufferedReader bf = new BufferedReader(new InputStreamReaderurlConnection .getInputStream()))，但是bf为null。

这是有道理的，因为如果我尝试直接在Chrome中打开链接，它会自动将此XML保存到我的本地磁盘，并且响应正文为空。在Firefox和IE中，我有机会打开它或另存为，只有在浏览器中打开时，响应才会包含XML文件。

有人能开导我一点吗？

编辑1：我尝试使用curl但似乎它不适用于https。这是一些代码：

URL qkrFileUrl = new URL(requestURL);

HttpURLConnection httpUrlConnection = (HttpURLConnection) qkrFileUrl
                .openConnection();
httpUrlConnection.setRequestProperty("Accept",
            "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8");
httpUrlConnection.setRequestProperty("Accept-Encoding",
                "gzip,deflate");
httpUrlConnection.setRequestProperty("Accept-Language:",
                "en-us,de-de;q=0.7,en;q=0.3");
httpUrlConnection.setRequestProperty("Connection:", "keep-alive");
httpUrlConnection.setRequestProperty("Host:",
                "connectionsww.demos.ibm.com");
httpUrlConnection.setRequestProperty("User-Agent",
                    Mozilla/5.0 (Windows NT 6.1; WOW64; rv:24.0) Gecko/20100101 Firefox/24.0");

httpUrlConnection.setAllowUserInteraction(false);
BufferedReader bufferedReader = new BufferedReader(
                new InputStreamReader(httpUrlConnection.getInputStream()));


        LOGGER.debug("bufferedReader Content is " + bufferedReader.toString());

        String line = null;
        String XMLFile = new String();
        while (bufferedReader.readLine() != null) {
            line = bufferedReader.readLine();
            LOGGER.debug("Line is " + line);
            XMLFile += line;
        }

        LOGGER.info("XML file from the qkr file is " + XMLFile);

，XMLFile为null。

请求属性与我在Chrome中发出请求的属性相同。如果我没有设置请求属性，我会在XMLFile中获得一些奇怪的javascript：

错误500：java.net.MalformedURLException：no protocol：if（self   ！= top）{try {// per Origin Origin Policy，尝试获得最佳位置   attributes，if（self.location.hostname！= top.location.hostname）{   top.location = self.location; }赶上（E）{   document.getElementsByTagName（'body'）[0] .style.display ='none'; }}    iContainer_skip_init = true; document.getElementsByTagName（“html”）[0] .className + =“   lotusui_ie lotusui_ie6“;＆lt; / script＆gt; document.getElementsByTagName（”html“）[0] .className + =”   lotusui_ie8“;＆lt; / script＆gt;
