php - Fatal error: Uncaught Error: Class 'Stomp' not found -


i've downloaded library available in: https://github.com/dejanb/stomp-php

and implemented following code: 

<?php     use fusesource\stomp\stomp;    (...) $data=array($data1,$data2, $data3, $data4); $json = json_encode($data, true);   $user = getenv("activemq_user");  if( !$user ) $user = "admin";  $password = getenv("activemq_password"); if( !$password ) $password = "password";  $destination  = '/topic/event'; $messages = 10000; $size = 256;  $data = "calls"; $body = $data; for($i=0; $i< $size; $i++) {   $body .= $data[ $i % 26]; }  try {   $url = 'tcp://localhost:61613';   $con = new stomp($url, $user, $password);    for($i=0; $i< $messages; $i++) {     $con->send($destination, $body);     if( $i%1000 == 0 ) {       echo "sent ".$i." messages\n";     }   }    $stomp->send($destination, "shutdown");  } catch(stompexception $e) {   echo $e->getmessage(); } }

and error:

fatal error: uncaught error: class 'stomp' not found in /opt/lampp/htdocs/skeleton-application/test.php:80

update: reinstalled using composer suggested @ https://github.com/stomp-php/stomp-php.

i required autoloader using

<?php require __dir__ . '/../vendor/autoload.php';

and added following imports

use stomp\client; use stomp\statefulstomp; use stomp\network\connection; use stomp\transport\message;

still same error... need special activemq broker or something? ran through console... still nothing

apart confusion package use, our code has following problems:

  • you haven't imported classes using, , thus, php cannot find classes within root namespace
  • you passing in parameters constructors , other methods aren't used, or have wrong type
  • you apparently have undefined variables (for example, $stomp undefined, or it's missing code example)

i suggest tackling these problems 1 one.

using fusesource/stomp-php

import classes using

adjust list of imports (these use statements) include classes referencing in code example:

use fusesource\stomp\exception\stompexception; use fusesource\stomp\stomp;

if there more classes package code example omits, include them in imports well.

remove unnecessary parameters

when create instance of fusesource\stomp\stomp, passing in parameters constructor doesn't use.

change

$con = new stomp($url, $user, $password);

to

$con = new stomp($url);

undefined variables

you have line of code reference undefined variable $stomp, intend use $con instead.

change

$stomp->send($destination, "shutdown");

to

$con->send($destination, new message("shutdown"));

using stomp-php/stomp-php

import classes using

adjust list of imports (these use statements) include classes referencing in code example:

use stomp\client; use stomp\exception\stompexception; use stomp\statefulstomp; use stomp\transport\message;

if there more classes package code example omits, include them in imports well.

remove unnecessary parameters

the constructor of stomp\stomp\statefulstomp has different signature of fusesource\stomp.

change

$con = new stomp($url, $user, $password);

to

$con = new statefulstomp(new client($url));

adjust parameters required type

the signature of send() has changed.

change

$con->send($destination, $body);

to

$con->send($destination, new message($body));

undefined variables

you have line of code reference undefined variable $stomp, intend use $con instead.

change

$stomp->send($destination, "shutdown");

to

$con->send($destination, new message("shutdown"));

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

python Tkinter Capturing keyboard events save as one single string -

is possible store keyboard events 1 string? code below stores 1 char , prints it. card reader or bar code reader, contains collection of character/ string not 1 character @ time. goal save char pressed text variable. from tkinter import * root = tk() def key(event): text= event.char text+= event.char print ("pressed", text) def callback(event): frame.focus_set() print ("clicked at", event.x, event.y) frame = frame(root, width=100, height=100) frame.bind("<key>", key) frame.bind("<button-1>", callback) frame.pack() root.mainloop() currently, creating text variable , everytime key() function gets called, , text stores last character typed. you can define text module level variable , , use module level text inside key function - text = '' def key(event): global text text+= event.char print("pressed", text)

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
