Laravel Debugbar：Laravel 调试工具条(集成PHP Debug Bar)

Laravel Debugbar

For Laravel 4, please use the 1.8 branch!

This is a package to integrate PHP Debug Bar with Laravel 5. It includes a ServiceProvider to register the debugbar and attach it to the output. You can publish assets and configure it through Laravel. It bootstraps some Collectors to work with Laravel and implements a couple custom DataCollectors, specific for Laravel. It is configured to display Redirects and (jQuery) Ajax Requests. (Shown in a dropdown) Read the documentation for more configuration options.

Note: Use the DebugBar only in development. It can slow the application down (because it has to gather data). So when experiencing slowness, try disabling some of the collectors.

This package includes some custom collectors:

• QueryCollector: Show all queries, including binding + timing
• RouteCollector: Show information about the current Route.
• ViewCollector: Show the currently loaded views. (Optionally: display the shared data)
• EventsCollector: Show all events
• LaravelCollector: Show the Laravel version and Environment. (disabled by default)
• SymfonyRequestCollector: replaces the RequestCollector with more information about the request/response
• LogsCollector: Show the latest log entries from the storage logs. (disabled by default)
• FilesCollector: Show the files that are included/required by PHP. (disabled by default)
• ConfigCollector: Display the values from the config files. (disabled by default)

Bootstraps the following collectors for Laravel:

• LogCollector: Show all Log messages
• SwiftMailCollector and SwiftLogCollector for Mail

And the default collectors:

• PhpInfoCollector
• MessagesCollector
• TimeDataCollector (With Booting and Application timing)
• MemoryCollector
• ExceptionsCollector

It also provides a Facade interface for easy logging Messages, Exceptions and Time

Installation

Require this package with composer:

composer require barryvdh/laravel-debugbar

After updating composer, add the ServiceProvider to the providers array in config/app.php

Laravel 5.5 uses Package Auto-Discovery, so doesn't require you to manually add the ServiceProvider

If you use a catch-all/fallback route, make sure you load the Debugbar ServiceProvider before your own App ServiceProviders.

Laravel 5.x:

Barryvdh\Debugbar\ServiceProvider::class,

If you want to use the facade to log messages, add this to your facades in app.php:

'Debugbar' => Barryvdh\Debugbar\Facade::class,

The profiler is enabled by default, if you have app.debug=true. You can override that in the config (debugbar.enabled). See more options in config/debugbar.php You can also set in your config if you want to include/exclude the vendor files also (FontAwesome, Highlight.js and jQuery). If you already use them in your site, set it to false. You can also only display the js or css vendors, by setting it to 'js' or 'css'. (Highlight.js requires both css + js, so set to true for syntax highlighting)

Copy the package config to your local config with the publish command:

php artisan vendor:publish --provider="Barryvdh\Debugbar\ServiceProvider"

Lumen:

For Lumen, register a different Provider in bootstrap/app.php:

if (env('APP_DEBUG')) {
 $app->register(Barryvdh\Debugbar\LumenServiceProvider::class);
}

To change the configuration, copy the file to your config folder and enable it:

$app->configure('debugbar');

Usage

You can now add messages using the Facade (when added), using the PSR-3 levels (debug, info, notice, warning, error, critical, alert, emergency):

Debugbar::info($object);
Debugbar::error('Error!');
Debugbar::warning('Watch out…');
Debugbar::addMessage('Another message', 'mylabel');

And start/stop timing:

Debugbar::startMeasure('render','Time for rendering');
Debugbar::stopMeasure('render');
Debugbar::addMeasure('now', LARAVEL_START, microtime(true));
Debugbar::measure('My long operation', function() {
    // Do something…
});

Or log exceptions:

try {
    throw new Exception('foobar');
} catch (Exception $e) {
    Debugbar::addThrowable($e);
}

There are also helper functions available for the most common calls:

// All arguments will be dumped as a debug message
debug($var1, $someString, $intValue, $object);

start_measure('render','Time for rendering');
stop_measure('render');
add_measure('now', LARAVEL_START, microtime(true));
measure('My long operation', function() {
    // Do something…
});

If you want you can add your own DataCollectors, through the Container or the Facade:

Debugbar::addCollector(new DebugBar\DataCollector\MessagesCollector('my_messages'));
//Or via the App container:
$debugbar = App::make('debugbar');
$debugbar->addCollector(new DebugBar\DataCollector\MessagesCollector('my_messages'));

By default, the Debugbar is injected just before
