eclipse - How can I retrieve a feed in JSON from a Java Servlet? -

-

I want to make a HTTP request and want to store the result in JSONObject. I have not done much work with servlets, so I am unsure what I am 1) request to be done properly, and 2) JSONObject should be made. I've imported JSONObject and JSONArray classes, but I do not know how I should use them. Here's what I have: 

  throws public zero doGet (httpPervateate request), IOException {// Try the URL {// with a single string. URL url = new URL (FEED_URL); // Server BufferedReader = Read all the text returned by the new BufferedReader (New InputStreamReader (url.openstream ()); String; While ((str = in.readLine ())! = Null {// str A line of text ; ReadLine () character of new line (s)} in.close () strips;} hold (malformedLELException e) {} catcher (IOException e) {}

My FEED_URL already It has been written so that it will return the formatted feed for JSON.

This is getting me for hours Thank you very much, you guys are a valuable resource!

Collect responses in the first string: 

  BufferedReader = in the new BufferedReader (New InputStreamReader (url.openstream ()); StringBuller FullSpons = New StringBuilder (); Letter string; while {(str = in.readLine ()) = null {fullResponse.append (str);}

After that, if the string starts with "{" You can use it: 

  JSONObject obj = new JSONObject (fullResponse.toString ()); // [1]

And if it starts with "[", then you can use it: 

  JSONArray arr = New JSONArray (FullResponse.toStrin ()); // [2]

c# - How to capture HTTP packet with SharpPcap -

-
I would like to capture all incoming HTTP packets on my machine. To do this, I am using SharpPcap which is a WinPcap The cover is. SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes.

jquery - SimpleModal Confirm fails to submit form -

-
I am trying to confirm jQuery to show yes / no confirmation when I submit a form. I had modified (in the last list) to capture and block form submissions. However, it only works with jQuery 1.2.6, a recent upgrade stops 1.3.2, if yes is clicked, then by submitting the form. But I can not understand what is wrong / inconsistent in my code now. Demo (which works in both versions of a simple window.href implementation). $ (document) .ready (function () {$ ('input.delete'). Click (function (e) {e.preventDefault (); var target = $ (e .target); Confirm ("Really delete this event?", Function () {target.click ()});});}); How about something like this? The idea of ​​catching clicks (and fire!) On the submitted event is not click event. $ (document) .ready (function () {$ ('# myForm'). Submit (function () {var f = this; Confirm (" Remove? ", Function () {$ (f). Submit ();}) Return; Return the initial session;}}}}; Hope That this is som
