在 Yii 2.0 报错：PHP Warning: strpos(): Empty needle in E:\wwwroot\pcs-api\vendor\yiisoft\yii2\log\Target.php on line 243 的分析解决
1、执行命令，报错：PHP Warning: strpos(): Empty needle in E:\wwwroot\pcs-api\vendor\yiisoft\yii2\log\Target.php on line 243，如图1

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 | PS E:\wwwroot\pcs-api> ./yii cmc-console-user/syncException 'yii\web\ServerErrorHttpException' with message 'Framework Service Console HTTP request failed: 租户信息不存在'in E:\wwwroot\pcs-api\common\services\CmcConsoleUserService.php:102Stack trace:#0 E:\wwwroot\pcs-api\console\controllers\CmcConsoleUserController.php(62): common\services\CmcConsoleUserService::httpGetUserList(Array)#1 [internal function]: console\controllers\CmcConsoleUserController->actionSync()#2 E:\wwwroot\pcs-api\vendor\yiisoft\yii2\base\InlineAction.php(57): call_user_func_array(Array, Array)#3 E:\wwwroot\pcs-api\vendor\yiisoft\yii2\base\Controller.php(157): yii\base\InlineAction->runWithParams(Array)#4 E:\wwwroot\pcs-api\vendor\yiisoft\yii2\console\Controller.php(148): yii\base\Controller->runAction('sync', Array)#5 E:\wwwroot\pcs-api\vendor\yiisoft\yii2\base\Module.php(528): yii\console\Controller->runAction('sync', Array)#6 E:\wwwroot\pcs-api\vendor\yiisoft\yii2\console\Application.php(180): yii\base\Module->runAction('cmc-console-use...', Array)#7 E:\wwwroot\pcs-api\vendor\yiisoft\yii2\console\Application.php(147): yii\console\Application->runAction('cmc-console-use...', Array)#8 E:\wwwroot\pcs-api\vendor\yiisoft\yii2\base\Application.php(386): yii\console\Application->handleRequest(Object(yii\console\Request))#9 E:\wwwroot\pcs-api\yii(23): yii\base\Application->run()#10 {main}PHP Warning: strpos(): Empty needle in E:\wwwroot\pcs-api\vendor\yiisoft\yii2\log\Target.php on line 243PHP Warning: strpos(): Empty needle in E:\wwwroot\pcs-api\vendor\yiisoft\yii2\log\Target.php on line 243PHP Warning: strpos(): Empty needle in E:\wwwroot\pcs-api\vendor\yiisoft\yii2\log\Target.php on line 243PHP Warning: strpos(): Empty needle in E:\wwwroot\pcs-api\vendor\yiisoft\yii2\log\Target.php on line 243 |
2、查看 \console\runtime\logs\app.log
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 | 2019-04-02 14:03:05 [-][-][-][warning][yii\log\Dispatcher::dispatch] Unable to send log via yii\log\DbTarget: PHP Warning 'yii\base\ErrorException' with message 'strpos(): Empty needle' in E:\wwwroot\pcs-api\vendor\yiisoft\yii2\log\Target.php:243Stack trace:#0 [internal function]: yii\base\ErrorHandler->handleError(2, 'strpos(): Empty...', 'E:\\wwwroot\\pcs-...', 243, Array)#1 E:\wwwroot\pcs-api\vendor\yiisoft\yii2\log\Target.php(243): strpos('yii\\base\\Applic...', '')#2 E:\wwwroot\pcs-api\vendor\yiisoft\yii2\log\Target.php(124): yii\log\Target::filterMessages(Array, 0, Array, Array)#3 E:\wwwroot\pcs-api\vendor\yiisoft\yii2\log\Dispatcher.php(189): yii\log\Target->collect(Array, false)#4 E:\wwwroot\pcs-api\vendor\yiisoft\yii2\log\Logger.php(177): yii\log\Dispatcher->dispatch(Array, false)#5 E:\wwwroot\pcs-api\vendor\yiisoft\yii2\log\Logger.php(124): yii\log\Logger->flush()#6 [internal function]: yii\log\Logger->yii\log\{closure}()#7 {main}2019-04-02 14:03:05 [-][-][-][info][application] $_GET = []$_POST = []$_FILES = []$_COOKIE = []$_SERVER = [] |
3、在命令行中编辑
1 2 | var_dump(strpos("Fabio", 'b'));exit; |
1 2 | PS E:\wwwroot\pcs-api> ./yii cmc-console-user/syncint(2) |
4、在命令行中编辑，在控制台命令行中一旦抛出异常，写入日志时，就会报错：PHP Warning: strpos(): Empty needle，如图2
图2
1 2 | var_dump(strpos("Fabio", ''));exit; |
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 | PS E:\wwwroot\pcs-api> ./yii cmc-console-user/syncPHP Warning 'yii\base\ErrorException' with message 'strpos(): Empty needle'in E:\wwwroot\pcs-api\console\controllers\CmcConsoleUserController.php:37Stack trace:#0 [internal function]: yii\base\ErrorHandler->handleError(2, 'strpos(): Empty...', 'E:\\wwwroot\\pcs-...', 37, Array)#1 E:\wwwroot\pcs-api\console\controllers\CmcConsoleUserController.php(37): strpos('Fabio', '')#2 [internal function]: console\controllers\CmcConsoleUserController->actionSync()#3 E:\wwwroot\pcs-api\vendor\yiisoft\yii2\base\InlineAction.php(57): call_user_func_array(Array, Array)#4 E:\wwwroot\pcs-api\vendor\yiisoft\yii2\base\Controller.php(157): yii\base\InlineAction->runWithParams(Array)#5 E:\wwwroot\pcs-api\vendor\yiisoft\yii2\console\Controller.php(148): yii\base\Controller->runAction('sync', Array)#6 E:\wwwroot\pcs-api\vendor\yiisoft\yii2\base\Module.php(528): yii\console\Controller->runAction('sync', Array)#7 E:\wwwroot\pcs-api\vendor\yiisoft\yii2\console\Application.php(180): yii\base\Module->runAction('cmc-console-use...', Array)#8 E:\wwwroot\pcs-api\vendor\yiisoft\yii2\console\Application.php(147): yii\console\Application->runAction('cmc-console-use...', Array)#9 E:\wwwroot\pcs-api\vendor\yiisoft\yii2\base\Application.php(386): yii\console\Application->handleRequest(Object(yii\console\Request))#10 E:\wwwroot\pcs-api\yii(23): yii\base\Application->run()#11 {main}PHP Warning: strpos(): Empty needle in E:\wwwroot\pcs-api\vendor\yiisoft\yii2\log\Target.php on line 243PHP Warning: strpos(): Empty needle in E:\wwwroot\pcs-api\vendor\yiisoft\yii2\log\Target.php on line 243PHP Warning: strpos(): Empty needle in E:\wwwroot\pcs-api\vendor\yiisoft\yii2\log\Target.php on line 243PHP Warning: strpos(): Empty needle in E:\wwwroot\pcs-api\vendor\yiisoft\yii2\log\Target.php on line 243 |
5、编辑 \console\config\main.php，调整日志组件的配置
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 | 'components' => [ 'log' => [ 'traceLevel' => YII_DEBUG ? 3 : 0, 'targets' => [ 'file' => [ 'class' => 'yii\log\FileTarget', 'levels' => ['error', 'warning'], ], 'db' => [ 'class' => 'yii\log\DbTarget', 'except' => ['*'], 'prefix' => function () { $url = !Yii::$app->request->isConsoleRequest ? Yii::$app->request->getUrl() : null; $user = Yii::$app->has('user', true) ? Yii::$app->get('user') : null; $userId = $user ? $user->getId(false) : '-'; return sprintf('[%s][%s][%s]', Yii::$app->id, $url, $userId); }, 'logVars' => [], ] ], ],], |
调整为：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | 'components' => [ 'log' => [ 'traceLevel' => YII_DEBUG ? 3 : 0, 'targets' => [ 'file' => [ 'class' => 'yii\log\FileTarget', 'levels' => ['error', 'warning'], ], 'db' => [ 'class' => 'yii\log\DbTarget', 'levels' => ['error', 'warning'], ], ], ],], |
6、在控制台命令行中一旦抛出异常，写入日志时，报错：PHP Warning: strpos(): Empty needle 的问题已经得到解决
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 | PS E:\wwwroot\pcs-api> ./yii cmc-console-user/syncPHP Warning 'yii\base\ErrorException' with message 'strpos(): Empty needle'in E:\wwwroot\pcs-api\console\controllers\CmcConsoleUserController.php:37Stack trace:#0 [internal function]: yii\base\ErrorHandler->handleError(2, 'strpos(): Empty...', 'E:\\wwwroot\\pcs-...', 37, Array)#1 E:\wwwroot\pcs-api\console\controllers\CmcConsoleUserController.php(37): strpos('Fabio', '')#2 [internal function]: console\controllers\CmcConsoleUserController->actionSync()#3 E:\wwwroot\pcs-api\vendor\yiisoft\yii2\base\InlineAction.php(57): call_user_func_array(Array, Array)#4 E:\wwwroot\pcs-api\vendor\yiisoft\yii2\base\Controller.php(157): yii\base\InlineAction->runWithParams(Array)#5 E:\wwwroot\pcs-api\vendor\yiisoft\yii2\console\Controller.php(148): yii\base\Controller->runAction('sync', Array)#6 E:\wwwroot\pcs-api\vendor\yiisoft\yii2\base\Module.php(528): yii\console\Controller->runAction('sync', Array)#7 E:\wwwroot\pcs-api\vendor\yiisoft\yii2\console\Application.php(180): yii\base\Module->runAction('cmc-console-use...', Array)#8 E:\wwwroot\pcs-api\vendor\yiisoft\yii2\console\Application.php(147): yii\console\Application->runAction('cmc-console-use...', Array)#9 E:\wwwroot\pcs-api\vendor\yiisoft\yii2\base\Application.php(386): yii\console\Application->handleRequest(Object(yii\console\Request))#10 E:\wwwroot\pcs-api\yii(23): yii\base\Application->run()#11 {main} |
