日志

composer create-project laravel/laravel log --prefer-dist "5.5.*"

# cd log
vim routes/web.php

<?php

Route::get('/', function () {
    Log::info('This is some useful information.');
    Log::warning('Something could be going wrong.');
    Log::error('Something is really going wrong.');
    return 'index';
});

echo "APP_LOG=daily" >> .env

• 测试

php artisan serve

curl localhost:8000 # 返回"index"

cat $(find storage/logs -name "[0-9a-zA-Z]*" | tail -n1)

[2018-04-27 09:29:23] local.INFO: This is some useful information.
[2018-04-27 09:29:23] local.WARNING: Something could be going wrong.
[2018-04-27 09:29:23] local.ERROR: Something is really going wrong.

#Linux
sed -i "s/APP_LOG_LEVEL=debug/APP_LOG_LEVEL=warning/g" .env

# MacOS
sed -i "" "s/APP_LOG_LEVEL=debug/APP_LOG_LEVEL=warning/g" .env

• 测试

# 更新.env配置后服务需要重启生效
php artisan serve

rm storage/logs/*.log

curl localhost:8000 # 返回"index"

cat $(find storage/logs -name "[0-9a-zA-Z]*" | tail -n1)

[2018-04-27 09:36:31] local.WARNING: Something could be going wrong.
[2018-04-27 09:36:31] local.ERROR: Something is really going wrong.

错误

composer create-project laravel/laravel bugsnag --prefer-dist "5.5.*"

注意

错误处理在app/Exceptions/Handler.php文件中

cat app/Exceptions/Handler.php| tail -25

    /**
     * Report or log an exception.
     *
     * This is a great spot to send exceptions to Sentry, Bugsnag, etc.
     *
     * @param  \Exception  $exception
     * @return void
     */
    public function report(Exception $exception)
    {
        parent::report($exception);
    }

    /**
     * Render an exception into an HTTP response.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Exception  $exception
     * @return \Illuminate\Http\Response
     */
    public function render($request, Exception $exception)
    {
        return parent::render($request, $exception);
    }
}

其中

在report函数中将错误上报到第三方错误统计平台中

在render函数中处理异常渲染HTTP响应

下面

我们将以第三方错误统计平台Bugsnag为例 来看一下错误处理的效果

# cd bugsnag
composer require "bugsnag/bugsnag-laravel:^2.0"

vim config/app.php

return [
    'providers' => [
        /*
         * Package Service Providers...
         */
        Bugsnag\BugsnagLaravel\BugsnagServiceProvider::class,
    ],
];

echo "BUGSNAG_API_KEY=***" >> .env

这里的BUGSNAG_API_KEY是在Bugsnag注册后得到的

vim app/Providers/AppServiceProvider.php

<?php

namespace App\Providers;

use Illuminate\Support\ServiceProvider;

class AppServiceProvider extends ServiceProvider
{
    public function boot()
    {
    }

    public function register()
    {
        $this->app->alias('bugsnag.logger', \Illuminate\Contracts\Logging\Log::class);
        $this->app->alias('bugsnag.logger', \Psr\Log\LoggerInterface::class);
    }
}

vim routes/web.php

<?php

use Bugsnag\BugsnagLaravel\Facades\Bugsnag;

Route::get('/', function () {
    Bugsnag::notifyException(new RuntimeException("Test error"));
    return 'index';
});

• 测试

php artisan serve

curl localhost:8000 # 返回"index"

此时 打开bugsnag管理后台可以看到错误报告如下
