Codeception例外：json_encode（）：類型不受支持

當試圖運行任何測試，我得到以下錯誤：Codeception例外：json_encode（）：類型不受支持

json_encode（）：類型不受支持，編碼爲空

我使用的是2.0版0.1

測試代碼：下面

$I = new ApiTester($scenario); 
$I->wantTo('get a list of all users'); 
$I->haveHttpHeader('Content-Type','application/x-www-form-urlencoded'); 
$I->sendGET('users'); // <-- error happens here 
$I->seeResponseCodeIs(200); 
$I->seeResponseIsJson(); 
$I->seeResponseContains('{ result: ok}');

輸出示例：

    I have http header "Content-Type","application/x-www-form-urlencoded" 

    I send get "users" 
    [Request] GET http://api.myapp.com/users

我也得到錯誤的Laravel默認的歡迎頁面簡單的驗收測試：

$I = new AcceptanceTester($scenario); 
$I->wantTo('see the Laravel welcome page'); 
$I->amOnPage('/'); 
$I->shouldSee('You have arrived.');

向我們展示您的測試用例代碼 – Unnawut

感謝@Unnawut，添加了測試代碼。 – Adamski

你確定你需要'$ I-> haveHttpHeader（'Content-Type'，'application/x-www-form-urlencoded'）;'？也許嘗試刪除該行。國際海事組織，做一個簡單的'GET'不應該需要，它可能會影響你的代碼是如何編碼/解碼JSON數據。 – Unnawut

這竟然是與沒有在php.ini中設置時區的問題。我添加了相關的行到/etc/php.ini，它現在可以工作。

例/etc/php.ini中：（PHP 5.4.19）

date.timezone = "Europe/London" 
error_reporting = E_ALL 
display_errors = On 
html_errors = On 

zend_extension=/usr/lib/php/extensions/no-debug-non-zts-20100525/xdebug.so 

extension=mcrypt.so
