最近在調試RESTful API示例時，出現以下錯誤：
1 { 2 "name": "Exception", 3 "message": "Class yii/web/JsonParser does not exist", 4 "code": -1, 5 "type": "ReflectionException", 6 "file": "/Users/Desktop/workspaces/php/yii2-ims/vendor/yiisoft/yii2/di/Container.php", 7 "line": 426, 8 "stack-trace": [9 "#0 /Users/Desktop/workspaces/php/yii2-ims/vendor/yiisoft/yii2/di/Container.php(426): ReflectionClass->__construct(‘yii/web/JsonPar...‘)", 10 "#1 /Users/Desktop/workspaces/php/yii2-ims/vendor/yiisoft/yii2/di/Container.php(364): yii\\di\\Container->getDependencies(‘yii/web/JsonPar...‘)", 11 "#2 /Users/Desktop/workspaces/php/yii2-ims/vendor/yiisoft/yii2/di/Container.php(156): yii\\di\\Container->build(‘yii/web/JsonPar...‘, Array, Array)", 12"#3 /Users/Desktop/workspaces/php/yii2-ims/vendor/yiisoft/yii2/BaseYii.php(345): yii\\di\\Container->get(‘yii/web/JsonPar...‘, Array)", 13 "#4 /Users/Desktop/workspaces/php/yii2-ims/vendor/yiisoft/yii2/web/Request.php(531): yii\\BaseYii::createObject(‘yii/web/JsonPar...‘)", 14 "#5 /Users/Desktop/workspaces/php/yii2-ims/vendor/yiisoft/yii2/rest/CreateAction.php(51): yii\\web\\Request->getBodyParams()", 15"#6 [internal function]: yii\\rest\\CreateAction->run()", 16 "#7 /Users/Desktop/workspaces/php/yii2-ims/vendor/yiisoft/yii2/base/Action.php(94): call_user_func_array(Array, Array)", 17 "#8 /Users/Desktop/workspaces/php/yii2-ims/vendor/yiisoft/yii2/base/Controller.php(157): yii\\base\\Action->runWithParams(Array)", 18 "#9 /Users/Desktop/workspaces/php/yii2-ims/vendor/yiisoft/yii2/base/Module.php(528): yii\\base\\Controller->runAction(‘create‘, Array)", 19 "#10 /Users/Desktop/workspaces/php/yii2-ims/vendor/yiisoft/yii2/web/Application.php(103): yii\\base\\Module->runAction(‘deptinfo/create‘, Array)", 20 "#11 /Users/Desktop/workspaces/php/yii2-ims/vendor/yiisoft/yii2/base/Application.php(386): yii\\web\\Application->handleRequest(Object(yii\\web\\Request))", 21 "#12 /Users/Desktop/workspaces/php/yii2-ims/api/web/index.php(10): yii\\base\\Application->run()", 22 "#13 {main}" 23 ] 24 }
其實，這是自己給自己挖的一個坑，結果把自己給陷進去了，下面是配置文件的代碼：
‘request‘ => [ ‘class‘ => ‘yii\web\Request‘, ‘parsers‘ => [ ‘application/json‘ => ‘yii/web/JsonParser‘, ], ],
問題就在於配置時將 “yii/web/JsonParser”寫錯了，正確的是 “yii\web\JsonParser”，命名空間應以反斜杠“\”分割，看似很小的問題，結果調試了很長時間才找到原因，所以在寫代碼配置的時候一定要認真仔細，以免被自己誤導，浪費寶貴的時間。
