使用HttpClient上传视频文件(Upload Video file using HttpClient)
我正在构建Java客户端，它将自动将文件从Java服务器上传到我使用他们的AMI安装在我的EC2云上的Panda Instance。 我正在尝试使用Apache HTTP Components上传到Panda Server（ Panda Stream ）。 它适用于我的浏览器客户端但由于某种原因我无法从该库上传。 这是我的代码：
String videoUploadUrl = "http://[panda server ip]/videos/" + getVideoID() + "/upload.xml"; File file = new File("/temp/videofile.mp4"); DefaultHttpClient httpclient = new DefaultHttpClient(); httpclient.getParams().setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1); HttpPost httppost = new HttpPost(videoUploadUrl); MultipartEntity mpEntity = new MultipartEntity(); ContentBody fBody = new FileBody(file); mpEntity.addPart("userfile", fBody); httppost.setEntity(mpEntity); System.out.println("executing request " + httppost.getRequestLine()); HttpResponse response2 = httpclient.execute(httppost); // <-- FAILS HERE System.out.println("finish executing request"); HttpEntity resEntity = response2.getEntity(); System.out.println(response2.getStatusLine()); if (resEntity != null) { System.out.println(EntityUtils.toString(resEntity)); } if (resEntity != null) { resEntity.consumeContent(); } httpclient.getConnectionManager().shutdown();这是我的错误日志。

I'm building Java client that will automatically upload file from Java server to Panda Instance that I installed on my EC2 cloud using their AMI. I'm trying to use Apache HTTP Components to upload to Panda Server (Panda Stream). It works fine with my browser client but for some reason I can't upload from that library. Here is my code:
String videoUploadUrl = "http://[panda server ip]/videos/" + getVideoID() + "/upload.xml"; File file = new File("/temp/videofile.mp4"); DefaultHttpClient httpclient = new DefaultHttpClient(); httpclient.getParams().setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1); HttpPost httppost = new HttpPost(videoUploadUrl); MultipartEntity mpEntity = new MultipartEntity(); ContentBody fBody = new FileBody(file); mpEntity.addPart("userfile", fBody); httppost.setEntity(mpEntity); System.out.println("executing request " + httppost.getRequestLine()); HttpResponse response2 = httpclient.execute(httppost); // <-- FAILS HERE System.out.println("finish executing request"); HttpEntity resEntity = response2.getEntity(); System.out.println(response2.getStatusLine()); if (resEntity != null) { System.out.println(EntityUtils.toString(resEntity)); } if (resEntity != null) { resEntity.consumeContent(); } httpclient.getConnectionManager().shutdown();And here is my error log.

Why I'm getting broken pipe. If I use same code to upload to some servlet then I work fine but not with panda Instance. Any idea?

尝试这个：
MyApp.TweetInputView = SC.View.extend({ didInsertElement: function() { console.log("I've been rendered!"); } });Try this:
MyApp.TweetInputView = SC.View.extend({ didInsertElement: function() { console.log("I've been rendered!"); } });
