javascript - How to output script file from remote sever on my php page using ajax -


i working on trying run script remote server , output html page using ajax user can see. have tried on local server up.sh , down.sh , works. however, when put 2 scripts on remote server, start ssh session , try output remote server, not show anything, nor give me errors. missing anything? can see hard coded '$gateway' remoteserver, later value textbox field in form.php user input. best way this?

form.php:

    <div id="gatewayinput">             <form>                     <input type="text" id="gateway" name="gateway" placeholder="gateway name"><br><br>             </form>     </div>  <div class="box1">   <form method="post">   <label class="col">up/down</label>   <span class="col">     <input type="radio" name="option" id="r1" value="1" />     <label for="r1">up</label>     <input type="radio" name="option" id="r2" value="2" />     <label for="r2">down</label>   </span>     <span class="col">       <input type="submit" class="button"/>     </span>   </form> </div>   <script src ="../../../jquerydir/jquery-3.2.1.min.js"></script> <script type="text/javascript">          $(".button").click(function(event){              if ((document.getelementsbyname("gateway")[0].value == '')) {                     alert('gateway required!');                     return false;              }              else if (document.queryselectorall('input[type="radio"]:checked').length < 1) {                     //console.log("radio button length value: " + document.queryselectorall('input[type="radio"]:checked').length);                     alert('please choose up/down value!');                     return false;              }              else {                     alert('sucess!');                     event.preventdefault();                     $.ajax({                             url:"testexe.php",                             type: "post",                             data: {option: $('input[type=radio]:checked').val()},                             datatype: "text",                             success:function(result){                             $('#div1').html(result)                             }                     });                     return true;             }        });

testexe.php

<?php  include 'res/php/functions.php'; $gateway = 'remoteserver'; $user = 'user'; $pass = 'pass';  function cleaninput($data) {     $data = trim($data);     $data = stripslashes($data);     $data = htmlspecialchars($data);     return $data; }  //when submit button clicked if ( $_server['request_method'] == 'post'){      //$gateway = cleaninput($_post['gateway']);        //create ssh connection     if ($connection = @ssh2_connect($gateway, 22)) {            ssh2_auth_password($connection, $user, $pass);             if(isset($_post['option']) && $_post['option'] == 1) {                  $output =                   shell_exec("/tmp/testscripts/up.sh");            }             if(isset($_post['option'])  && $_post['option'] == 2) {                  $output =                   shell_exec("/tmp/testscripts/down.sh");            }            //remove   if want see $output in file             echo "<pre>$output</pre>";      }  }  ?>

i fixed following:

if ( $_server['request_method'] == 'post'){      //$gateway = cleaninput($_post['gateway']);        //create ssh connection     if ($connection = @ssh2_connect($gateway, 22)) {            ssh2_auth_password($connection, $gwuser, $gwpwd);            //mkdir(/tmp/moslehpour/testscripts, 0777, true);            //ssh2_scp_recv($connection, './aust/conf/hosts', $workdir . '/hosts')            if(isset($_post['option']) && $_post['option'] == 1) {                  $stream = ssh2_exec($connection, "/tmp/user/testscripts/up.sh");                 stream_set_blocking($stream, true);                 $stream_out = ssh2_fetch_stream($stream, ssh2_stream_stdio);                 echo stream_get_contents($stream_out);             }             if(isset($_post['option'])  && $_post['option'] == 2) {                  $stream = ssh2_exec($connection, "/tmp/user/testscripts/down.sh");                 stream_set_blocking($stream, true);                 $stream_out = ssh2_fetch_stream($stream, ssh2_stream_stdio);                 echo stream_get_contents($stream_out);            }       }   }

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
