node.js - Prevent direct access to html page in node js -

-

I would like to stop the user from typing directly in the URL of the page and going to the page. How do I get this functionality in node? I know that they do not have direct access to web applications in web applications to keep files under file.

If you are using, then you can check the referrer in the middleware like this in the middleware, Which you can further customize as necessary for your exact purposes: 

  var Express = requirement ('Express') var app = express () allowed lamp = ['localhost' '127.0.0.1']; // which can link here? App.use (function (req, res, next) {var i = 0, notfound = 1, referer = req.get ('referrer'); if ((req.path === '/') || (req .path === '')) Next (); // pass call '/' always if (referrer) {while ((I and LT; permission lamp lamp) & amp; amp; not; found =) (Notfound = (referer.indexOf permission linker [i]) === - 1); i ++;}} if (notfand) {res.status (403) .seend ('protected area. Enter .mysite.com ');} else {next (); // login is allowed, go to the next step in the simple path}}); App.get ('/', function (rik, ridge) {res.send ('& lt; p & gt; Hello you are on the main page. & Lt; / p & gt; & lt; a href = "page2 "& Gt; Page 2 ; ';}); App.get (' / page2 ', function (rik, ridge) {res.send (' & lt; p & gt; 2) ;);}); app.listen (3000); // test http: // localhost: 3000   
 test (and countermessor)  
 Can we get the main page?  yes     wget http: // localhost: 3000 / --2014-10-10 04: 01: 18-- http: // localhost: 3000 / resolution localhost (localhost) ... 127.0.0.1 localhost (Localhost) | 127.0.0.1 |: 3000 ... Added HTTP request sent, waiting for response ... 200 right length: 67 [text / html] Saving them: One? ??? index.html ???? / code>  
 Can we get another page directly?  No   
  wget Http: // localhost: 3000 / page2 --2014-10-10 04: 04: 34 - http: // localhost: 3000 / page2 Resolve localhost ... 127.0.0.1 from localhost Is connected. 127.0.0.1 |: 3000 ... Added HTTP request sent, waiting for response ... 403 Forbidden 2014-10-10 04:04:34 Error 403: Forbidden   
 What Can we get the second page from the first page?  Yes     wget --referer = "http: // localhost" http: // localhost: 3000 / page2 --2014-10-10 04:05: 32 - http: // localhost: 3000 / page2 Resolving localhost (localhost) ... 127.0.0.1 is linked to localhost (localhost). 127.0.0.1 |: 3000 ... Added HTTP request sent, awaiting response ... 200 right length: 24 [text / html] Saving: One Page Page 2  < / Pre> 
 Can someone learn Kiddie Wget --referer to defeat this "security" plan?  
  Yes it only blocks honest people, not a person who really wants content.

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

.net - Creating a new Queue Manager and Queue in Websphere MQ (using C#) -

-
"itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
