api - php+curl to send a post request with fields -


Trying to send post request to the API, to get an image back.

Example url: 

  https://providers.cloudsoftphone.com/lib/prettyqr/createQR.php?user=1003123&format=png&cloudid=asdasdasd& The above URL works well in the browser, if the API does not request / postes, then  
 The result of my code is always  Invalid input '.  
 Code:  
  $ url = 'https: //providers.cloudsoftphone.com/lib/prettyqr/createQR.php'; $ U = RAND (); $ P = rand (); $ Fields = array ('user' = & gt; urlencode ($ u), 'pass' => urlencode ($ p), 'format' = & gt; urlencode ('jpg'), 'cloud' = & Gt; urlencode 'test')); $ Ch = curl_init (); Curl_setopt ($ CH, CURLOPT_URL, $ url); Curl_setopt ($ CH, CURLOPT_RETURNTRANSFER, 1); Curl_setopt ($ CH, CURLOPT_POST, 1); Curl_setopt ($ CH, CURLOPT_POSTFIELDS, $ fields); Curl_setopt ($ CH, CURLOPT_SSL_VERIFYPEER, incorrect); $ Output = curl_xac ($ CH); Curl_close ($ ch); $ Echo output;   
 One note: Is there a way to debug the request to see what is being sent?   
 
 
 The URL provided is not working for the  POST  request. Here is the resulting screenshot (I have tried to use)  
 Enter image details here  
 Although it is fully working with the  GET  method, you can continue to use the GET request method to generate QR code.  
 I believe that GET is not more secure than POST method but when requesting curl user, in your case URL address (user id, password) will not be known.  Because  curl  will be sent from your web server and not from the client / user's browser.   
 Later you can only output that response image, which you received from the API.

How can I add a seperate action listener to all 14 of my buttons at once that can determine player turn?(java) -

I have a big code, for a game I'm calling Tommy's Kumamak. I know that this is not beautiful, but I am very naive and for some reasons I know from using arrays, anyway, my problem is that I can not add a variable outside the listener and within the action listener I can modify the variable (pTurn ++) from How can I go about adding a count to that variable from inside the action listener? 1 error was found: file: c: \ user \ public \ togiz_kumalak.java [line: 130] error: local variables pTurn is accessed from within internal class; Need to be declared final int pTurn = 0; Button1.addActionListener {new zero-action action (action event e) {pTurn ++; if (pTurn% 2 == 0) {display.append ("\ n Player 2 cup 1");} If ( PTurn% 2! = 0) {display.append ("\ nPlayer 1Cup 1")}}); In that case, move the contents of the functionalities into orbit and then call the action For example, display the method from: Private Zero Button Press {pTurn ++; If (pTurn% 2...
