如何在CakePHP 3.2中获取上次运行的查询? [英] How to get last run query in CakePHP 3.2?
问题描述
我想在CakePHP 3.2中获得最后执行的查询,我之前在CakePHP 2.x中使用了以下内容:-
I want to get the last executed query in CakePHP 3.2, I have used the following in CakePHP 2.x before:-
function getLastQuery() {
Configure::write('debug', 2);
$dbo = $this->getDatasource();
$logs = $dbo->getLog();
$lastLog = end($logs['log']);
$latQuery = $lastLog['query'];
echo "<pre>";
print_r($latQuery);
}
如何在CakePHP 3.x中做到这一点?
How can i do it in CakePHP 3.x?
推荐答案
简而言之:您只需要修改 config/app.php
In plain English: All you need to do is modify config/app.php
找到Datasources
配置并设置'log' => true
'Datasources' => [
'default' => [
'className' => 'Cake\Database\Connection',
'driver' => 'Cake\Database\Driver\Mysql',
'persistent' => false,
'host' => 'localhost',
...
'log' => true, // Set this
]
]
如果您的应用程序处于调试模式,则当页面显示SQL错误时,您现在将看到SQL查询.如果没有启用调试模式,则可以通过添加以下内容将SQL查询记录到文件中:
If your app is in debug mode, you will now see the SQL query when your page displays a SQL error. If you do not have debug mode on, you can log the SQL queries to a file by also adding the following:
config/app.php
找到Log
配置并添加新的日志类型:
Find the Log
configuration and add a new log type:
'Log' => [
'debug' => [
'className' => 'Cake\Log\Engine\FileLog',
'path' => LOGS,
'file' => 'debug',
'levels' => ['notice', 'info', 'debug'],
'url' => env('LOG_DEBUG_URL', null),
],
'error' => [
'className' => 'Cake\Log\Engine\FileLog',
'path' => LOGS,
'file' => 'error',
'levels' => ['warning', 'error', 'critical', 'alert', 'emergency'],
'url' => env('LOG_ERROR_URL', null),
],
// Add the following...
'queries' => [
'className' => 'File',
'path' => LOGS,
'file' => 'queries.log',
'scopes' => ['queriesLog']
]
],
您的SQL查询现在将被写入一个日志文件,您可以在/logs/queries.log
Your SQL queries will now be written to a log file which you can find in /logs/queries.log
